Everything for Amazon Sellers—in One Base.

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. ...

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). ...

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. ...

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. ...

For most US sellers, the first Amazon marketplace to expand to is Canada, Mexico or Brazil, because all three sit inside the account you already have. Amazon’s global expansion guide says a US seller needs a “Professional North America and Brazil unified account, which you can use to sell in the US, plus Canada, Mexico, and Brazil” (sell.amazon.com, data checked 2026-10-04). Europe, the Asia-Pacific and the Middle East each need another account. That split, plus one fee rule for linked accounts, sets the order of the decision. The demand data in the Sell Globally dashboard and Marketplace Product Guidance then tells you which country inside that order is worth the work. ...

To sell on Amazon Europe from the US, you create a regional Europe account — from your Amazon.com Professional account if you already have one, or through the Sell Globally dashboard after opening a North America and Brazil unified account if you are new. Amazon says a business outside Europe “may not be required to form a Europe-based company to sell your products in Europe” (data checked 2026-10-04). Then you choose FBA or merchant fulfillment, and before your first unit ships you answer the VAT question, because storing or selling goods in an EU country can require a VAT registration there. ...

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. ...

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 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. ...

To sell on Amazon Japan from the US, you open a Japan account through Amazon’s Sell Globally program — from your existing Amazon.com Professional account, or after creating a North America and Brazil unified account if you are new — then pick FBA in Japanese fulfillment centers or merchant fulfillment, and clear Japan’s product rules before you list. Amazon says a business outside Japan “may not be required to form a Japan-based company” (data checked 2026-10-03). That “may not” is where the real work sits: importing, consumption tax and regulated products each bring their own Japanese requirement. ...

To sell on Amazon India from the US, you add an India account to your Amazon.com Professional account through the Sell Globally dashboard, then choose between FBA and shipping orders yourself (FBM). The catch is FBA: Amazon’s US page says that “To sell in India using FBA, you will first need to connect with a trade compliance consultant using our Service Provider Network” (data checked 2026-10-03). The reason sits on Amazon.in, not on the US page: “The Indian regulations do not permit global entities to engage in direct B2C (business to customer) retail.” ...
