Yes, you can resell branded products in most cases. A legal principle called the first sale doctrine says that once a genuine branded item has been lawfully sold, the buyer can resell it without the brand owner’s permission. That protection is broad, but it isn’t unconditional. How you source the product, whether you change it in any way, how you describe it to buyers, and whether you handle taxes properly all decide whether your resale stays legal.
Why Reselling Is Legal in the First Place
The first sale doctrine is the foundation. In trademark law, courts have consistently held that a brand owner’s control over a product ends after the first authorized sale. The Ninth Circuit has said that reselling a trademarked product under the producer’s trademark “and nothing more” is not actionable misrepresentation. For copyrighted works like books, music, and software, the same idea is codified: once you own a lawfully made copy, you can sell it without the copyright holder’s consent.1Office of the Law Revision Counsel. 17 USC 109 – Limitations on Exclusive Rights: Effect of Transfer of Particular Copy or Phonorecord
Focus on the phrase “and nothing more.” The doctrine protects you when the product you resell is genuine and in the same condition the brand sold it in. Once you change the product, remove something a buyer would expect, or advertise it in a way that suggests you’re connected to the brand, the protection starts to fall away.
When You Lose First Sale Protection
The most common way resellers lose the doctrine’s protection is by offering products that are “materially different” from what the brand sells through its authorized channels. Courts have set the bar for materiality low. In Davidoff & CIE, S.A. v. PLD International Corp., the Eleventh Circuit described a material difference as anything a consumer would “consider relevant to a decision about whether to purchase a product,” and said even subtle differences count.2vLex. Davidoff and CIE v PLD Intl Corp, 263 F3d 1297 (11th Cir 2001) In that case, removing batch codes from perfume bottles was enough.
Missing Warranty Coverage
Most manufacturer warranties only apply when the product was bought from an authorized retailer. If you resell a product and your buyer can’t get warranty service, courts have repeatedly treated the missing warranty as a material difference on its own. In Patagonia, Inc. v. McHugh (2020), otherwise genuine Patagonia products were found materially different for that reason alone. Survey evidence in a related case showed 85% of consumers said a warranty made them more likely to buy.
Repackaging, Relabeling, and Storage
Physical changes create risk. Removing labels, rebundling items sold as sets, transferring products into new containers, or mishandling temperature-sensitive goods can all count as material alterations. In Warner-Lambert Co. v. Northside Development Corp., the court upheld a brand’s right to enforce quality standards on resold products, meaning modifications or improper handling that affect quality can eliminate first sale protection.3Justia. Warner-Lambert Co v Northside Dev Corp
The practical rule: keep the product exactly as you received it. Save receipts and documentation showing where it came from. If storage conditions matter, document that you met them.
Gray Market Goods
Gray market goods are genuine branded products originally intended for sale in another country. They aren’t counterfeits, but they can still cause legal problems. A brand might sell a European version with different ingredients, different packaging, instructions in another language, or no U.S. warranty coverage. When those products come into the U.S. and get resold, the differences between the foreign version and the authorized domestic version can support a trademark infringement claim.
Courts look at whether the imported goods are materially different from the domestic ones. Formulation, packaging language, included accessories, warranty availability, and regulatory compliance can all qualify. Risk climbs sharply when the imported version fails U.S. regulatory standards, which can trigger fines, seizures at customs, and in extreme cases criminal charges for willful import violations.
If you buy from overseas suppliers, confirm the goods are identical in every meaningful way to the U.S. version. Get supplier documentation on origin and specifications. When in doubt, compare the product side by side with the authorized version before listing it.
How You Advertise the Product
Even genuine, unaltered products can create trademark liability if you market them badly. The question is consumer confusion: does your listing suggest you’re the brand, or an authorized dealer when you aren’t?
Federal trademark law prohibits using a registered mark in a way likely to confuse consumers about the source or sponsorship of goods.4Office of the Law Revision Counsel. 15 USC 1114 – Remedies; Infringement; Innocent Infringement by Printers and Publishers You can use the brand name to describe what you’re selling. You can’t use logos, trade dress, or language that implies affiliation. Putting a brand’s logo across your store banner, calling yourself an “authorized retailer” when you’re not, or copying the brand’s packaging style all cross the line.
Courts weigh the likelihood of confusion using a multi-factor test from Polaroid Corp. v. Polarad Electronics Corp., considering things like the strength of the mark, similarity between uses, and actual confusion evidence.5Justia. Polaroid Corp v Polarad Electronics Corp, 287 F2d 492 (2d Cir 1961) The practical lesson is simple: be transparent that you’re an independent reseller, and use brand names only to identify the product accurately.
Using the Brand’s Product Photos
Many resellers copy a brand’s professional images for their listings. Those photos are protected by copyright from the moment they’re taken.6U.S. Copyright Office. What Photographers Should Know About Copyright Using them without permission can add a copyright claim on top of any trademark issue. Brands with registered photos can sue in federal court or bring claims before the Copyright Claims Board for damages up to $30,000 per proceeding.
Take your own photos of the actual item you’re selling. That also helps prove authenticity if a listing is ever challenged.
Counterfeits: Where Civil Law Turns Criminal
Selling counterfeits is a different category of risk. A counterfeit isn’t just an unauthorized copy. It’s a product bearing a fake version of a registered trademark, designed to make buyers think it’s the real thing. The penalties are severe, and they matter even to honest sellers because an unreliable supplier can put counterfeits in your inventory without your knowledge.
On the civil side, brand owners can pursue statutory damages of $1,000 to $200,000 per counterfeit mark per type of goods, and up to $2,000,000 per mark if the counterfeiting was willful.7Office of the Law Revision Counsel. 15 USC 1117 – Recovery for Violation of Rights Those figures stack when multiple products or marks are involved.
Federal criminal penalties are harsher. A first offense carries up to $2,000,000 in fines and up to 10 years in prison for an individual, or up to $5,000,000 in fines for a business entity. Repeat offenders face doubled maximums: up to $5,000,000 and 20 years for individuals, and up to $15,000,000 for entities.8Office of the Law Revision Counsel. 18 USC 2320 – Trafficking in Counterfeit Goods or Services
Buy only from suppliers you can verify. Keep invoices, certificates of authenticity, and any correspondence documenting origin. If a deal looks too good to be true from an unfamiliar overseas source, it usually is.
Cease-and-Desist Letters
Brands sometimes push back on resellers even when the products are genuine and properly marketed. A cease-and-desist letter from a brand’s law firm often lists trademark infringement, unfair competition, and false designation of origin. The volume of claims can be intimidating, but many of them fall apart when the reseller is offering genuine, unaltered goods and clearly disclosing that they aren’t an authorized dealer.
One claim tends to carry weight regardless of authenticity: tortious interference with contract. If a brand has contracts with its authorized distributors restricting resale to unauthorized third parties, and you knowingly benefit from a breach of those contracts, the brand may have a real case. Knowing your supplier isn’t allowed to sell to you is the key ingredient.
Getting a cease-and-desist letter doesn’t mean you broke the law. It means someone’s lawyer wants you to stop. Ignoring it is risky, because a later lawsuit can use your silence against you. Immediate capitulation isn’t required either. For letters involving significant dollar amounts or threats of litigation, a trademark attorney is worth the fee.
Platform Rules on Amazon and eBay
Selling on major marketplaces adds a private layer of enforcement on top of the law. Platforms don’t need a court order to shut you down.
Amazon’s Brand Registry lets trademark owners report suspected infringement, and enrolled brands can use tools like Project Zero to remove listings immediately.9Amazon. Amazon Brand Registry Amazon also runs a Counterfeit Crimes Unit that works with law enforcement. When a listing is flagged, the reseller usually has to prove the product is genuine with invoices, supplier letters, or other sourcing documents. Slow or incomplete responses often end in listing removal or account suspension.
eBay’s VeRO (Verified Rights Owner) program works similarly for rights holders. Platform enforcement is fast and discretionary, and appeals are notoriously hard. Organized sourcing records are your best defense against losing selling privileges.
Taxes on Resale Income
Reselling is a business, and the IRS treats it that way. Every dollar of profit is taxable, and once your operation reaches scale, tax forms make the income harder to overlook.
Form 1099-K
Payment processors and online marketplaces send a Form 1099-K when gross payments exceed $20,000 across more than 200 transactions in a calendar year.10Internal Revenue Service. Understanding Your Form 1099-K That’s gross revenue, not profit, so thin-margin sellers can trigger it. You owe tax on your net profit whether or not you receive the form. The form just means the IRS also knows.
Deducting Costs
You can deduct your cost of goods sold, which directly reduces taxable income. Buy something for $50 and sell it for $80, and you’re taxed on the $30 profit, less other deductible business expenses such as shipping, platform fees, and supplies. Most small resellers qualify for a simplified inventory method if their average annual gross receipts are $30 million or less: deduct the purchase cost of each item in the year it sells, without formal inventory valuations.
Report the activity on Schedule C of your federal return. Keep receipts for every purchase. Track sales and expenses throughout the year rather than trying to reconstruct them at tax time. Platform sales reports help but miss costs incurred off-platform.
Sales Tax and Resale Certificates
When you buy inventory to resell, you generally don’t owe sales tax on those purchases. A resale certificate tells your supplier the goods are for resale, exempting the transaction from sales tax. You then collect sales tax from the buyer when you sell at retail and remit it to the state.
Using a resale certificate usually requires a sales tax permit from your state. Most states issue these for free; a few charge small registration fees. Fill the certificate out accurately and keep it on file. Using one to buy items for personal use is tax fraud.
Online sellers also face economic nexus rules. Since the Supreme Court’s 2018 Wayfair decision, states can require out-of-state sellers to collect sales tax after crossing a sales threshold in that state. Most states set it at $100,000 in annual sales, though some go higher. Five states have no general sales tax at all. For the rest, tracking sales by state and registering where required is part of running a legitimate resale business.
Most resellers who get in trouble aren’t selling fakes. They’re selling genuine products but cutting corners on sourcing, storage, marketing, or paperwork. Careful records and honest advertising head off most of the problems before they start.
