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. ...

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. ...

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. ...

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. ...

A Children’s Product Certificate (CPC) is a written certificate, issued by the US manufacturer or, for anything made abroad, the importer, stating that a children’s product passed testing at a third-party, CPSC-accepted laboratory against every children’s product safety rule that applies to it. For an Amazon seller importing kids’ goods from an overseas factory, the certifier is the importer of record, not the factory: CPSC’s FAQ, read on 2026-10-05, says “an importer cannot simply pass along a foreign manufacturer’s certificate of conformity.” Amazon asks for a CPC through its compliance requests and lists what the certificate must carry. ...

If you import food into the US for Amazon FBA, two FDA filings sit in front of the shipment: the factory that makes or packs the food must hold an FDA food facility registration, and someone must submit FDA Prior Notice for each shipment before it reaches the US port. According to FDA’s guidance What You Need to Know About Prior Notice of Imported Food Shipments (data checked 2026-10-05), Prior Notice is due no less than 2 hours before arrival by road, 4 hours by rail or air, and 8 hours by water, and “any individual with knowledge of the required information” can submit it. Food with inadequate Prior Notice “is subject to refusal and, if refused, must be held at the port of entry” unless directed to another location. ...

To sell supplements on Amazon you clear two separate systems: federal law, where FDA does not approve your product before launch but you carry full responsibility for its safety and label, and Amazon’s own dietary supplements policy, which requires every listed product to be verified through an Amazon-authorized third-party testing, inspection, and certification (TIC) provider. FDA states plainly that “Under DSHEA, FDA does not have the authority to approve dietary supplements before they are marketed” (Questions and Answers on Dietary Supplements, checked 2026-10-05). Amazon, on its side, writes: “To list on Amazon, you must work with a direct product validation authorized third-party testing, inspection, and certification (TIC) service provider to verify all notified ASINs” (Dietary supplements policy, checked 2026-10-05). ...

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. ...

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.” ...

Amazon Automate Pricing is the free repricing tool built into Seller Central: you pick a rule, set a minimum price (and optionally a maximum), and Amazon changes your price for you within those limits. It is free with the Professional selling plan, it offers three rule types (competitive, sales-based, and business price), and Amazon says price updates on existing rules are “usually processed in less than 15 minutes” (sell.amazon.com, data checked 2026-10-04). What it cannot do is win the Featured Offer on price alone, because Amazon also weighs inventory, fulfillment, and customer service. ...

Amazon Growth Opportunities is a free Seller Central dashboard that ranks product-level recommendations — run an ad, add A+ Content, enroll in Vine, fix a listing, cut a cost — by their estimated impact on your sales. You open it from Growth → Growth Opportunities in the Seller Central main menu, and it sorts every recommendation into four types: Sell New Products, Improve Sales, Reduce Cost, and Drive Traffic (Amazon’s tool page, checked 2026-10-04). The tool is free to use, but many of the actions it recommends — advertising, Vine, some fulfillment programs — cost money. ...

Amazon View in 3D lets shoppers rotate, pinch and zoom a 3D model of your product in the Amazon shopping app, and View in Your Room uses augmented reality to place it in their own space. Amazon states that “There is no cost for adding 3D models and augmented reality to your Amazon product listings” (checked 2026-10-04). You can get a model three ways: upload your own GLB or glTF file through Image manager, scan the product with the Amazon Seller app’s Create 3D Models feature, or hire a 3D modeling provider through the Service Provider Network. ...
