Everything for Amazon Sellers—in One Base.

Selling cosmetics on Amazon in the US now sits on two layers: the Modernization of Cosmetics Regulation Act of 2022 (MoCRA), which FDA summarizes as facility registration, product listing, safety substantiation, and 15-business-day serious adverse event reporting, and Amazon’s own Beauty approval, which lists “Modernization of Cosmetics Regulation Act (MoCRA) compliance documentation” among the documents a seller may need to provide (FDA MoCRA page, content current as of Aug 10, 2026; Amazon, How to sell beauty products, dated Feb 17, 2026; both checked 2026-10-07). ...

You can put an unqualified “Made in USA” on an Amazon listing or package only if the product is “all or virtually all” made in the U.S.: final assembly or processing in the U.S., all significant processing in the U.S., and all or virtually all ingredients or components made and sourced in the U.S. That is the Federal Trade Commission’s standard, and it covers online marketing as well as the box. Short of it, a qualified claim such as “Made in USA of U.S. and imported parts” works only if it is truthful, substantiated, and the product has significant U.S. content or processing. ...

Amazon clothing label requirements in the US start with federal law, not with Amazon. Under the FTC’s rules for the Textile and Wool Acts, a garment label has to show three things: the fiber content, the country of origin, and either the company name or the company’s Registered Identification Number (RN). A separate FTC rule adds a care label with washing or drycleaning instructions, and when you sell online, the product description itself needs a clear statement that the item is “made in U.S.A.,” “imported,” or both. ...

FTC Mail Order Rule for FBM Sellers: The 30-Day Rule, Delay Notices, and Refunds The FTC’s Mail, Internet, or Telephone Order Merchandise Rule (16 CFR Part 435) says a merchant needs a “reasonable basis” for any shipping time it states, and, when it states none, a reasonable basis for believing it can ship within 30 days. If the order cannot ship on time, the FTC’s business guide says the merchant must either get the buyer’s consent to the delay through a “delay option notice” or cancel and refund. As of 2026-10-07, the guide lists civil penalties of up to $53,088 per violation. ...

Under US federal law, a UV sanitizer, an ultrasonic pest repeller or a bug zapper sold on Amazon is usually an EPA pesticide device, not a registered pesticide: it carries an EPA Establishment Number and no EPA Registration Number. EPA’s consumer guide states that the establishment number “does NOT indicate that the product has been reviewed for safety or efficacy by EPA” (Pesticide Devices: A Guide for Consumers, checked 2026-10-07). Once a product adds a chemical to do the pest-killing, or a listing promises that it “kills germs,” the rules change, and the claims on the page become the thing EPA reads first. ...

To find the HTS code for your Amazon product, you classify it yourself under the Harmonized Tariff Schedule of the United States (HTSUS): pick the 4-digit heading whose legal text and notes describe the product, apply the six General Rules of Interpretation (GRIs) in order, narrow down to the 8-digit tariff line, then add the 2-digit statistical suffix to reach 10 digits. Before you commit, search CBP’s CROSS database for rulings on similar goods, and if real doubt remains, ask CBP for a binding ruling. Under 19 U.S.C. 1484 the legal duty to classify sits with the importer of record, not with Amazon, your supplier, or a code-lookup website. ...

Duty drawback is the US customs program that refunds duties you paid on imported goods once those goods (or qualifying substitutes) are exported or destroyed. For an Amazon FBA seller, that means duty drawback can return up to 99 percent of the eligible duties on inventory you imported and later shipped out of the US or destroyed under customs rules, as long as you file in ACE within five years of the import date (19 CFR 190.51 and CBP’s drawback page, data checked 2026-10-06). Duties on goods you sold to US customers do not come back. ...

CPSC eFiling is the requirement, in effect since July 8, 2026, that importers of CPSC-regulated consumer products electronically file certificate of compliance data with U.S. Customs and Border Protection (CBP) at entry. It covers any finished product that needs a certificate, which means General Certificates of Conformity (GCCs) for non-children’s products as well as Children’s Product Certificates (CPCs). The importer supplies seven data elements, or three certificate identifiers from CPSC’s Product Registry, and the customs broker transmits them. Shipment value does not matter: CPSC’s FAQ says there is no de minimis exemption. ...

Amazon FBA lithium battery requirements come down to three things: complete battery information at listing, a UN 38.3 test summary at ASIN setup, and a battery exemption sheet uploaded to Manage dangerous goods classification. Amazon’s lithium battery help page states all three, and attaches one consequence to the first: “If the battery information that you provide is incomplete, inaccurate, or otherwise conflicting, your product may be blocked for sale through FBA” (Requirements for lithium batteries and products powered by lithium batteries, checked 2026-10-06). On top of the paperwork sits a size limit: whether a cell or battery is accepted depends on its watt-hours and on the marketplace. ...

Amazon Attribution for Sellers: What It Measures, Who Is Eligible, How to Build Tags, and How to Read the Metrics Amazon Attribution is Amazon’s free tool for measuring what happens on Amazon after a shopper clicks a link you placed somewhere else — a Google ad, a TikTok post, an email, an influencer’s review. You build a tagged URL for each campaign tactic, put it in place of your plain Amazon link, and Amazon reports the detail page views, add-to-carts, purchases, sales, and new-to-brand orders that followed the click within a 14-day window. Professional sellers need a brand enrolled in Amazon Brand Registry to use it. ...

Prop 65 on Amazon comes down to two documents: California’s warning regulations, which put the warning duty mainly on the manufacturer, producer, packager, importer, supplier, or distributor, and Amazon’s own help page, which tells every seller to “Determine if the product needs a Prop 65 warning” and submit it through the listing’s Compliance attributes (Amazon Seller Central, G202141960, checked 2026-10-05). The same Amazon page states that this applies “even if you have fewer than 10 employees, and even if someone else is selling the same product.” ...

Short answer: if your FBA inventory travels to the United States by ocean, someone has to send CBP an Importer Security Filing (ISF, also called “10+2”) before the container is loaded at the origin port. The legally responsible party is the “ISF Importer” — usually you, the brand owner buying the goods — even when a freight forwarder or customs broker presses the button. Eight of the ten data elements are due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port, and CBP’s mitigation guidelines allow a $5,000 liquidated damages claim per late ISF (CBP ISF FAQ, May 2023 edition, checked 2026-10-05). Air and express shipments are outside the rule. ...
