Selling on Best Buy Marketplace: who can sell, fees, FCC and UL certification, e-waste fees, entity and tax set-up (2026)

Best Buy Marketplace is the third-party seller platform on BestBuy.com and the Best Buy app. It opened on August 19, 2025, on Mirakl's software. It is curated: you apply and get reviewed. In its first year it accepted only sellers with a U.S. physical presence; in fiscal Q3 2026 Best Buy began adding international sellers.

Best Buy announced the marketplace on January 16, 2025 and launched it in August, calling it the largest expansion of its assortment ever: online selection more than doubled, with new or larger categories in gaming and mobile accessories, small appliances, floor care, furniture, seasonal décor, toys, musical instruments and movies. Best Buy earns from seller commissions and fees and from Best Buy Ads.

Description: read top to bottom; each row is a milestone, what happened, and what it means for sellers.

• Separate from Canada: Best Buy Canada (bestbuy.ca) has run its own marketplace for years under different rules; for example, Canadian marketplace items can't be returned in stores. This guide covers the U.S. site.
• Where international onboarding stands: on the August 27, 2026 call, management said it would begin adding international sellers "later this quarter" (the quarter ended in early November 2026). As of November 9, 2026 Best Buy had not published which countries or categories are open; Q3 results are expected in late November.
• The rules move: commission rates, product attributes and performance metrics were all updated in 2025 and 2026. Check the Seller Hub (partners.bestbuy.com/seller-hub) before applying.

Applications start at BestBuy.com/Marketplace and run through four steps: contact information, business information, product information, and fulfillment and delivery. Best Buy reviews before it offers a seller agreement; after approval come know-your-customer and credit checks, registration with the payment provider, and a certificate of insurance. U.S. sellers generally apply with a U.S. company; foreign sellers follow the international seller terms added in July 2026, which require them to act as importer and ship from a U.S. warehouse.

The first step asks for your name, title, e-mail, phone and your relationship to the company (direct employee or independent rep group); Best Buy says the title routes the application to the right review team. Later steps cover the company, brands, categories, SKU count and fulfillment capability.

Description: each row is a requirement, with how it applies to U.S. sellers and to international sellers (not resident or incorporated in the U.S.). The international terms come from the addendum in the July 2026 seller standard terms.

Requirement	U.S. seller	International seller
Entity	U.S. LLC or corporation; nothing published on individual sellers	Foreign company; Best Buy may ask for proof of brand ownership or authorization
Tax form	Generally a W-9 (EIN or SSN)	The terms require a W-8 (generally W-8BEN-E)
Payouts	U.S. bank account, registered with Best Buy's payment provider	An account that accepts USD wire transfers, also registered with the provider
Fulfillment	Own warehouse or a 3PL; Best Buy provides no storage	Must ship from a U.S. warehouse; the seller is importer of record, and Best Buy is never importer or consignee
Returns	To the seller's warehouse or business address	A U.S. return address; customers can't be asked to ship abroad
Customer service	Reply within 1 business day, in English	Also a U.S. toll-free number; warranty, logistics and support performed in the U.S. must be done by a U.S. resident or U.S. company
Warranty	At least 1 year on new products; 90 days on pre-owned and refurbished	A warranty valid in the U.S., or an equivalent one from the seller
Insurance	Commercial general liability from $1,000,000, $2,000,000 or $5,000,000 by category, with Best Buy as additional insured	Same; coverage territory includes the U.S. and Canada
Compliance	U.S. product safety, labeling and environmental fees are the seller's job	Same, plus country of origin, English descriptions, and possible supplier code of conduct self-assessments and audits

• Everything has to match: the company name, address and EIN must agree across state formation documents, the IRS EIN letter (CP 575 or 147C), the bank account, the W-9 and the insurance policy, and the insured has to be the company that onboards.
• Brand authorization: selling another company's brand needs a chain of authorization, and the standard terms bar relisting products bought from other marketplaces to fill orders.
• Sanctions and export controls: sellers represent that they are not in a comprehensively sanctioned jurisdiction, not on the Commerce Entity List or OFAC lists, and not 50% or more owned by listed parties.
• What the review looks at: Best Buy publishes no scorecard. From public materials: fit with Best Buy's brand and assortment, complete product data, fulfillment and service capacity, and competitive pricing (the terms ask for prices competitive in the aggregate with similar marketplaces).

Commissions run from 8% to 15% by category, applied to item price plus the shipping you charge, and each store pays a $29.99 monthly platform fee once its first sale happens. Finished devices (computers, TVs, phones, tablets, game consoles, cameras, major appliances) are mostly 8%; accessories, batteries and power, software, drones, home goods and toys mostly 15%; small appliances 12%. The Seller Hub table is for reference; the Marketplace Portal controls.

Description: each row is a category and its rate. Commission = rate × (item price + shipping fee). The Marketplace Portal has the full, binding list.

Category	Commission
Computers, tablets, eReaders, computer components, data storage, networking	8%
TVs, projectors, players, headphones, speakers and other A/V components	8%
Phones, radios, wearables, telephones	8%
Game console hardware; cameras and lenses; major appliances; security; printers; dash cams	8%
Small appliances; 3D printers; printer ink; car audio and automotive accessories	12%
Computer, mobile, A/V and tablet accessories; game controllers and accessories; software	15%
Batteries and power; drones; health and beauty; home, outdoor and seasonal; toys; musical instruments; pet	15%
Furniture	15% on the first $200 of price, 10% above $200
Lawn and garden, generators, power stations	15% at an average price of $500 or less, 8% above $500

• Shipping is commissioned too: the base includes the shipping you charge. Free-shipping listings pay commission on price only.
• Commission may not come back on returns: if you give partial refunds or handle returns outside the policy, Best Buy can keep the commission; if a returned item sits unprocessed for 4 business days, Best Buy refunds the customer, debits you, and may keep the commission.
• Platform fee: one per store, non-refundable; if payouts don't cover it, Best Buy asks for payment within 15 business days.
• Ads: Best Buy Ads self-service spend is deducted from your account. Best Buy has said ads and marketplace commissions both drive its gross margin; keep ad spend in its own account in your books.
• Payouts: invoiced weekly and paid 14 days after the invoice by EFT; refunds, chargebacks and return freight are deducted immediately. Best Buy can require a reserve and hold disputed amounts. Disputes over deductions must be filed within 60 days of the payment date.

Best Buy collects payment, carries card fraud, and takes in store returns; the seller handles inventory, shipping, delivery, service, warranty and recalls. Orders generally ship within 2 business days, may be canceled if not marked shipped in 3, and should arrive within 7 days. The return window is 15 days, and sellers can't charge restocking fees.

Description: each row is a metric, its threshold and what it measures. Business hours follow the store's business days and hours set in Mirakl.

Metric	Threshold	What it measures
Acceptance rate	At least 95%	Orders accepted and committed
Acceptance time	Within 8 business hours	Average time from order to acceptance
Cancellation rate	At most 4%	Accepted order lines with a cancellation
Late shipment rate	At most 5%	Orders shipped after the deadline
Tracking rate	At least 95%	Orders with valid tracking
Late delivery rate	At most 10%	Orders delivered after the promise date, last 30 days
Incident rate	At most 4%	Order lines with an incident
Return rate	At most 15%	Order lines with at least one return
Response time	Within 10 business hours	Average reply time to order messages

• How returns flow: for online returns Best Buy issues a prepaid label and the customer ships to you, with freight deducted from your payout. For store returns the store refunds the customer and ships the item back on Best Buy's account, again at your cost. Process returns in the portal within 1 business day of receipt; after 2 business days they may be refunded automatically. Large or LTL items can't be returned in stores; you coordinate those with the customer.
• No member extension: the 60-day window for My Best Buy Plus and Total members doesn't apply to marketplace items, and opened software, movies and games can't be returned.
• Warranty: new products with a mechanical or electrical component carry at least one year, with the seller covering any gap in the manufacturer's warranty; pre-owned and refurbished products carry 90 days under separate guidelines.
• Recalls: notices, CPSC reporting and all costs belong to the seller, including Best Buy's costs for returns, disposal and customer goodwill; corrected units need a new UPC.
• Chargebacks: Best Buy carries card fraud when you ship exactly per the order; non-fraud chargebacks, or missing proof of delivery within 2 business days, fall on you.
• Service: answer Best Buy and customer inquiries within 1 business day; repeated delays can suspend the account.

Selling electronics on Best Buy means at least four checks: safety certification by an NRTL (a lab recognized by OSHA, such as UL, Intertek ETL or CSA) for every electronic product; FCC authorization for devices that emit radio frequency; hazmat-compliant shipping for lithium batteries, with Best Buy accepting only installed or packed lithium-ion batteries under 300 watt-hours; and at least a one-year warranty on new products. Labs and lawyers handle certification and labeling; the cost goes into product cost.

• NRTL safety certification: Best Buy's safety standards page requires every consumer electronic product to be certified to applicable safety standards by an NRTL. Have certificates and test reports ready; Best Buy can ask for supporting documents within 5 calendar days.
• FCC authorization: intentional radiators such as Wi-Fi and Bluetooth devices need certification through a TCB and an FCC ID; many other digital devices use a Supplier's Declaration of Conformity (SDoC). Labels and manuals must match the authorization.
• New FCC lab rules: since 2025 the FCC no longer recognizes test labs and certification bodies controlled by "prohibited entities." On October 29, 2026 the FCC voted to stop recognizing, from December 1, 2028, labs located in countries without a mutual recognition agreement with the U.S., which includes China. Those labs stay recognized during the transition, but plan testing for new products early. Rely on the final text as published by the FCC.
• Drones: since December 22, 2025, foreign-produced drones and critical components are on the FCC Covered List, so new models generally can't get new FCC authorizations; existing authorizations stand. Talk to a lawyer before listing drones.
• Lithium battery shipping: lithium batteries need UN38.3 testing and DOT hazmat packaging and marking. Best Buy's excluded products list bars hazardous materials except lithium-ion batteries contained in or packed with equipment (UN3481) under 300 watt-hours each, lithium metal batteries in or with equipment (UN3091) under 25 grams of lithium, and non-spillable wet batteries (UN2800). A separate hazmat addendum applies.
• Other items: children's products need third-party testing and a CPC, and regulated imported consumer products require electronic certificate filing at import from July 8, 2026; California sales may need Prop 65 warnings; Best Buy has attributes for flame-retardant chemicals and Washington cookware restrictions. Don't claim the U.S. Cyber Trust Mark unless the product qualifies.
• Insurance: product liability coverage is a condition of selling. Computers, tablets, TVs, phones, batteries, cameras, game consoles and appliances need $2,000,000; e-mobility devices, generators, products with batteries of 300 watt-hours or more, humanoid robots and similar need $5,000,000; policies must be written on an occurrence basis.

Some states add recycling fees to electronics on top of sales tax. California charges its e-waste fee on covered video display devices ($4, $5 or $6 by screen size) and, from January 1, 2026, a covered battery-embedded fee on products whose batteries can't easily be removed (1.5% of price, capped at $15 per item). Best Buy's tax page lists these among the fees it collects, which depends on sellers setting product attributes correctly. Brand owners may also have to register with state electronics recycling (EPR) programs and pay annual fees, which the platform doesn't do for you.

Description: each row is a state fee or registration, with what it covers, the amount, who collects, and what the seller does. Amounts follow the latest state notices.

Item	Covers	Amount	Who collects	Seller's job
California e-waste recycling fee	Covered video display devices (TVs, monitors, laptops and similar)	$4 for 4" to under 15"; $5 for 15" to under 35"; $6 for 35" and up (readopted for 2026)	On Best Buy's list of fees it collects	Set screen size and category correctly
California covered battery-embedded (CBE) fee	Products whose battery can't be removed with common household tools (e-waste-fee devices excluded)	1.5% of price, up to $15 per item (2026 rate)	On Best Buy's list of fees it collects	Set "Contains Embedded Battery" to Yes or No in the listed categories; errors can block California sales, and Best Buy passes resulting costs to the seller
North Carolina white goods disposal tax	Refrigerators, washers and other major appliances	$3 per item per Best Buy's page	On Best Buy's list of fees it collects	Set major appliance attributes correctly
Prepaid wireless E911 and similar fees	Prepaid phones and similar	Varies by state	On Best Buy's list of fees it collects	Set category attributes correctly
Electronics EPR registration	"Manufacturers" selling electronics under their own brand	State registration and recycling fees	The seller registers and pays the state	Check CA, CT, IL, MN, NJ, NY, OR, PA, SC, TX, VT, WA and other states

• The contract puts environmental costs on you: the standard terms make sellers responsible for recycling, packaging and environmental fees and registrations arising from their sales, whatever the law says about allocation; if Best Buy pays, it can charge you. The international terms also ask foreign sellers to register in the U.S. where needed so Best Buy isn't held liable.
• These fees aren't your revenue: recycling fees Best Buy collects, like sales tax, are collected for the state; they are neither your income nor your expense. EPR registration and recycling fees you pay as a manufacturer are your business expense.
• CBE scope: phones, earbuds, fitness bands and electric toothbrushes with non-removable batteries can all be covered; display devices already paying the e-waste fee are excluded. CalRecycle sets each next year's rate by October 1, so the 2027 rate may change.

Best Buy calculates, collects and remits sales tax and certain fees on marketplace orders as a marketplace facilitator in every state with a sales tax, and sellers may not add tax to orders themselves. Best Buy also issues 1099-Ks by January 31 to sellers over the threshold. Off-platform sales, income and franchise tax in inventory states, and state registrations for your own brand are not the platform's job.

• Coverage: Best Buy's tax page lists every state with a sales tax; Delaware, Montana, New Hampshire and Oregon have none, and Alaska has local tax only. The seller terms add that Best Buy's determination governs "regardless of" the seller's location, order origin or sales volume in a state.
• Exempt orders: Best Buy may accept exemption certificates from eligible customers; refunded tax is passed to the seller and offsets the next payment.
• 1099-K: the federal threshold is more than $20,000 and more than 200 transactions a year (restored retroactively by OBBBA in July 2025); some states use lower thresholds. The 1099-K is gross, including shipping, before commissions and returns, and must reconcile to the weekly settlements (see yclcpa.com/1099k).
• Backup withholding: the terms let Best Buy withhold taxes it is legally required to. A missing W-9, or a name and TIN that don't match IRS records, means 24% withheld from payouts.
• Off-platform sales: sales tax on your own site, wholesale and in-person sales is yours; tools like Stripe Tax calculate it, but registration and returns are still on you (see yclcpa.com/stripetax). For North Carolina, see yclcpa.com/salestax.
• Inventory states: with a 3PL, wherever your goods sit you have physical presence. Federal P.L. 86-272 generally doesn't protect sellers with inventory in the state and doesn't reach gross-receipts taxes like the Texas franchise tax or Washington B&O (more at yclcpa.com/fba).

U.S. residents usually start with a single-member LLC and look at S corporation status once profits are steady. A single-member LLC owned by one foreign person is disregarded for tax, files pro forma 1120 + 5472 every year and tends to get the W-9 versus W-8 question wrong, so larger sellers often use a C corporation or have the LLC elect corporate treatment on Form 8832. A Chinese factory can onboard through a U.S. subsidiary or, now that Best Buy is opening up, directly as an international seller; the tax results differ.

Description: each row is a type of seller, with the usual entity, the form given to Best Buy, the federal filings and what to watch. Every case needs its own review.

Your situation	Usual entity	Form to Best Buy	Federal filings	Watch for
U.S. resident (citizen, green card holder, resident alien)	Single-member LLC; S corporation once profits are steady	W-9 (a disregarded LLC uses the owner's information)	Schedule C; 1120-S for an S corporation; 1120 for a C corporation	15.3% self-employment tax; an S corporation pays a reasonable salary (yclcpa.com/scorp)
U.S. LLC owned by one foreign individual	Wyoming or Delaware LLC	Per the W-9 instructions the foreign owner gives a W-8 (W-8ECI for effectively connected income); if the platform only offers a W-9, ask first	Pro forma 1120 + 5472; the owner files 1040-NR if there is effectively connected income	U.S. inventory and sales raise ECI risk; Form 8832 can elect corporate treatment, generally locked for 60 months
Chinese company with a U.S. subsidiary	Delaware or Wyoming C corporation	W-9	Form 1120 (21% federal) + 5472	Intercompany pricing under §482; imported inventory cost capped at customs value (§1059A); dividends 30% withholding, generally 10% under the treaty
Chinese company onboarding directly as an international seller	The Chinese company	W-8BEN-E	Form 1120-F if there is ECI; a treaty no-PE position generally still means filing and disclosing on Form 8833	You are the importer; U.S. warehousing and support must be done by U.S. third parties; state obligations separately
Multi-platform seller (Amazon, Walmart, Best Buy, own site)	One U.S. company, or one per brand	The same W-9 details on every platform	One combined return per company	Combine inventory states across platforms; one set of books by channel

• Foreign-owned single-member LLC: disregarded for income tax, but it files pro forma 1120 + 5472 by April 15 each year, by fax or mail, at $25,000 per missed form (see yclcpa.com/5472). Under the W-9 instructions, a disregarded entity with a foreign owner doesn't give a W-9 as a U.S. person; the foreign owner gives a W-8 (see yclcpa.com/w8ben).
• Effectively connected income risk: with inventory in U.S. warehouses sold through a U.S. platform to U.S. customers, a foreign owner may be engaged in a U.S. trade or business, making the income ECI reportable on 1040-NR or 1120-F. Under the U.S.–China treaty, business profits without a permanent establishment are generally not taxed in the U.S., but independent 3PLs, U.S. employees and agents who conclude contracts all change the answer; this needs a case-by-case review.
• Form 8832: an LLC can elect to be taxed as a corporation, becoming a C corporation for tax purposes at 21% federal with Form 5472 on the 1120, which also straightens out the W-9. Under Reg. §301.7701-3(c)(1)(iv), after a change in classification you generally can't change again for 60 months. Whether and when a foreign-owned LLC should elect is analyzed in full at yclcpa.com/walmart; C corporation pros and cons are at yclcpa.com/ccorp.
• No S corporation: foreign individuals and companies can't be shareholders.
• A U.S. subsidiary: the price the factory charges the U.S. subsidiary drives both U.S. income tax and customs value and duty, and the two need to line up (see yclcpa.com/subsidiary). A foreign person forming a U.S. company with 10% or more of the vote files BEA's BE-13 within 45 days.
• State: compare formation states at yclcpa.com/llc and entity types at yclcpa.com/entity. Inventory in California or crossing its doing-business thresholds brings the $800 minimum franchise tax; the Texas franchise tax no-tax-due threshold for 2026 and 2027 reports is $2,650,000, with an information report still due below it.
• ITIN: a foreign owner who must file 1040-NR without an SSN applies for an ITIN with the return; YCL is an IRS Certifying Acceptance Agent, so the passport doesn't go to the IRS (see yclcpa.com/itin).

International sellers on Best Buy must be the importer of record; Best Buy is never the importer or consignee. U.S. sellers buying from China decide the importer through their purchase terms. As of November 2026, Section 301 tariffs on Chinese-origin electronics remain (25% or 7.5% on most lists), with another 12.5% added from July 24, 2026; non-EV lithium-ion batteries are at 25% from 2026 and semiconductors at 50%. Duties, inbound freight and brokerage all go into inventory cost.

• Tariff layers: for electronics the usual layers are the general duty (zero for many electronics), Section 301 (the 2018 lists, the 2024 increases and the 2026 forced-labor action) and Section 232 duties on certain advanced chips. IEEPA tariffs were stopped by the Supreme Court on February 20, 2026, and importers of record can claim refunds. The full layer table is Figure 3 at yclcpa.com/aigo.
• De minimis: the $800 exemption has been suspended for all countries since August 29, 2025; Best Buy requires shipping from U.S. warehouses anyway, so the direct-parcel model doesn't work here.
• Importer duties: a U.S. company acting as importer registers with CBP, and formal entries (generally over $2,500) need a customs bond; the broker prepares HTS codes, origin and value, and the importer is responsible for them. Under DDP the forwarder is importer and holds the duties and any refunds; your inventory cost still needs the actual duty documents.
• Inventory cost: purchase price, inbound freight, duties, brokerage and delivery to the warehouse go into inventory and become cost of goods sold when sold; keep year-end quantities and values. More at yclcpa.com/fba.

A vendor (1P) sells wholesale to Best Buy, which becomes the seller, sets the retail price and collects tax from customers. A marketplace seller (3P) sells on BestBuy.com as the seller of its own goods, ships its own orders, and pays commission while Best Buy collects sales tax. Vendors work through the Best Buy partner portal (partners.bestbuy.com) under Best Buy's standard terms, EDI, product data management (PDM) and inbound shipping standards; the bar is higher than for the marketplace.

• Both can run in parallel: the partner portal separates the marketplace application from the vendor login, and registering as a prospective vendor doesn't guarantee business.
• The tax difference: as a vendor you make a wholesale sale to Best Buy, and the delivery terms set where title passes and who imports; as a marketplace seller you sell directly to U.S. consumers, so income and state obligations sit closer to the U.S. A Chinese factory that only supplies Best Buy and does nothing else in the U.S. is in a very different U.S. income tax position from one selling on the marketplace; review it first.

Best Buy's customer base centers on electronics and appliances, stores take returns, and the bar is high (safety certification, insurance, warranty); sellers ship their own orders and there is no FBA-style program. Amazon and Walmart bring more traffic and platform warehouses; Wayfair buys wholesale from suppliers; Etsy is handmade and niche; TikTok Shop runs on content and creators. Rules change; the table is as of November 2026.

Description: each row is a platform, with who the seller is, main fees, fulfillment, who can join, sales tax, 1099 and payouts. Rates are typical for common categories.

Platform	Seller of record	Main fees	Fulfillment	Who can join	Sales tax	1099	Payouts
Best Buy Marketplace	Seller	8%–15% commission (on price plus shipping) + $29.99/month per store	Seller-fulfilled; no Best Buy storage	Application; U.S. presence required until international sellers began in fiscal Q3 2026	Best Buy collects	Best Buy issues 1099-K	Weekly invoice, paid 14 days later
Amazon	Seller	Professional plan $39.99/month + 8%–15% in most categories	FBA or seller-fulfilled	Open registration, including Chinese sellers	Amazon collects	Amazon issues 1099-K	Generally every 14 days
Walmart Marketplace	Seller	No monthly fee; most referral fees 6%–15%, electronics mostly 8%	WFS or seller-fulfilled	Application; Walmart lists China among eligible countries	Walmart collects	Walmart issues 1099-K	Settlement cycle (see yclcpa.com/walmart)
Wayfair	Wayfair (suppliers sell wholesale to it)	No commission; wholesale cost	Supplier drop-ship or CastleGate	Supplier application, including overseas suppliers	Wayfair collects from customers	Generally no 1099-K for wholesale proceeds	Supplier payment terms (see yclcpa.com/wayfair)
Etsy	Seller	$0.20 listing + 6.5% transaction + payment processing	Seller-fulfilled	Open, including sellers abroad	Etsy collects	Etsy issues 1099-K	Etsy Payments schedule
TikTok Shop	Seller	About 6% in most categories + creator commissions	Platform logistics or approved warehouses	Local stores need a U.S. entity; cross-border usually by invitation	TikTok collects	TikTok issues 1099-K	Settlement cycle (see yclcpa.com/tiktok)
Shopify store	You	Plan fee + payment processing	You or a 3PL	Anyone	You register and collect	Shopify Payments issues 1099-K	Processor schedule

• Same 1099-K threshold: over $20,000 and over 200 transactions federally, with the platform as filer. One company selling on several platforms gets one 1099-K from each, and together they reconcile to the books.
• The electronics mix: many electronics brands sell on Amazon, Walmart, Best Buy and Newegg together (see yclcpa.com/newegg). Because Best Buy is seller-fulfilled, one 3PL can ship self-fulfilled orders for several platforms; combine inventory states for state tax.
• Best Buy's trade-off: store returns, brand standing and an electronics audience on one side; higher insurance, certification, warranty and return freight costs, and 15% commission on accessories, on the other.

Best Buy invoices weekly and pays 14 days later, net. Book gross sales, then commissions, the platform fee, ads, return freight, chargebacks and reserves separately. Sales tax and recycling fees Best Buy collects are not revenue. Cost inventory by unit, including duties and inbound freight.

• Revenue at gross: item price and shipping you charge are revenue; sales tax, e-waste and battery fees collected by Best Buy are not.
• Separate expenses: commission, the $29.99 platform fee, Best Buy Ads, return labels, 3PL storage and delivery, insurance, certification testing and EPR fees each get their own account.
• Returns and warranty: returns reduce revenue; resalable units go back to inventory and the rest are written off; warranty repairs and replacements are booked as incurred, with larger expected costs estimated at period end (for tax, generally deducted as incurred).
• Reserves and deductions: a reserve Best Buy holds is your receivable, not an expense; dispute deductions within 60 days and record the outcome.
• Reconciliation: match each weekly settlement to bank deposits and the year to the 1099-K; multi-platform sellers keep one set of books by channel.
• Annual filings: a C corporation files 1120 (with 5472 if 25% or more foreign-owned); a foreign-owned single-member LLC files pro forma 1120 + 5472; an S corporation files 1120-S; state returns and annual reports follow each state's dates.

Get five things in place before you apply: the entity and EIN records matching, the right W-9 or W-8, NRTL and FCC documentation for the products, insurance that meets category requirements, a U.S. warehouse and return address, and a bookkeeping method with inventory costing settled.

Description: each row is a task, the documents it needs, and who does it.

Task	Documents	Who does it
Entity	State formation documents, EIN letter (CP 575 or 147C), good standing; Form 5472 filed for foreign-owned companies	YCL helps
Tax form	W-9 or W-8BEN-E / W-8ECI, with name and TIN matching IRS records	YCL helps
Bank and payouts	U.S. bank account in the company's name (international sellers: a USD wire account); payment provider registration	You, with YCL checking the details
Product certification	NRTL safety certification, FCC authorization, UN38.3 test summary, CPC for children's products, Prop 65 review	Test labs and lawyers
Brand	Trademarks, authorization chain	Trademark lawyer
Insurance	Product liability at $1,000,000 / $2,000,000 / $5,000,000 with Best Buy as additional insured	Insurance broker
Warehouse and returns	U.S. warehouse (own or 3PL), U.S. return address, 2-business-day handling	You and your 3PL
Imports	Importer of record, customs broker, bond, HTS codes and duty estimates	Customs broker; YCL puts it into cost
State obligations	Inventory-state review; electronics EPR registrations; California attributes (screen size, embedded battery)	YCL on the tax side; you or a service provider for EPR

Example (hypothetical numbers, to show the method): Mr. Chen owns a wireless earbud factory in Shenzhen with its own brand and has sold on Amazon for two years. In 2026 he wants to add Best Buy and has two routes: A, wait for Best Buy's international program and onboard the Shenzhen company directly; B, form a Delaware C corporation that buys from the factory and onboards as a U.S. seller.

First, margin on one pair (price $59.99, free shipping, A/V components at 8%):

On California orders the customer also pays sales tax and the battery-embedded fee ($59.99 × 1.5% ≈ $0.90), collected by Best Buy; it is neither Mr. Chen's revenue nor his cost, but the "Contains Embedded Battery" attribute must be set to Yes.

Then the tax difference between the routes (12,000 pairs a year):

Neither route wins outright. A skips the U.S. company and Form 5472 but makes the factory the importer, leaves permanent establishment and state tax questions open, and depends on Best Buy actually accepting it. B is cleaner for W-9, banking and insurance and lets one U.S. company serve every platform, at the cost of a corporate return and intercompany pricing documentation each year. The choice depends on volume, whether profit should stay in the U.S., and whether you'll hire in the U.S.

Start with whether you have a U.S. entity and whether its filings are clean, then decide which role you want on Best Buy. Common situations:

• Situation A: a U.S. resident already selling electronics accessories on Amazon or Walmart. Apply with your existing LLC or company with matching records and W-9; work out margins after Best Buy's commission, return freight, insurance and certification; review inventory states across platforms together.
• Situation B: a Chinese owner with a U.S. LLC used for Amazon. Check that pro forma 1120 + 5472 has been filed every year and that the W-9 or W-8 was right; consider a Form 8832 election or a C corporation before applying to Best Buy.
• Situation C: a Chinese factory with its own brand that wants to sell directly. Watch the scope of Best Buy's international program, and compare onboarding directly with forming a U.S. subsidiary: importer duties, tariffs, permanent establishment, Form 5472 and intercompany pricing.
• Situation D: becoming a Best Buy vendor (1P). Go through the partner portal and prepare EDI, product data and inbound standards; settle delivery terms and the importer first, then decide whether you need a U.S. company.
• Situation E: already selling, with an IRS or state letter or a platform document request. Submit the letter at yclcpa.com/notice and we check the deadline and amount; for company and tax documents the platform wants, work from the pre-onboarding checklist.
