Does Amazon FBA require an HS code?

Amazon does not assign HS codes for you. Your inbound shipment crosses a border, so the commercial invoice your freight forwarder or carrier files needs an HS code for customs to assess duty. Get it wrong and the shipment can be held or hit with a surprise duty bill before it ever reaches the fulfillment center.

Who is responsible for the HS code on an FBA shipment?

You are, as the importer of record. Many sellers let their freight forwarder auto-classify, but the legal responsibility for an accurate code sits with the importer. Forwarder auto-classification is wrong often enough to cause five-figure surprise bills, so it pays to confirm the code yourself.

What happens if my FBA shipment has the wrong HS code?

Three things, often together: you overpay duty if the wrong code carries a higher rate, the shipment gets held while customs resolves the discrepancy (which can trigger storage fees and missed restock windows), and you risk penalties for a pattern of misclassification.

Amazon FBA HS Code: Classify Imports Before You Ship

Does Amazon FBA need an HS code?

Yes, on every inbound shipment that crosses a border. Amazon does not classify your products for you. When your freight forwarder or carrier files the commercial invoice, customs uses the HS code on it to decide the duty. Amazon just receives the boxes once they clear. The classification, and the responsibility for getting it right, sits with you as the importer of record.

The freight-forwarder auto-classification trap

Most FBA sellers never pick a code. They hand the forwarder a packing list and the forwarder auto-classifies. That is convenient, and it is wrong often enough to hurt. We have seen a single shipment land a $7,500 surprise bill because a forwarder dropped a product into a higher-duty heading. The forwarder is not the importer of record. You are. The bill, and any penalty for a pattern of misclassification, lands on your account.

Why this got worse in 2025

The de minimis exemption ended. US imports under $800 used to clear duty-free. That is gone, so even small replenishment parcels now need a declared HS code and owe duty.
Tariffs spiked. Effective rates on common categories climbed from 31.5% in late 2023 to 176.5% by April 2025. A wrong code at the higher rate is no longer a rounding error, it is a margin killer.
Holds cost more than duty. A held shipment can blow past your restock window, drive your listing out of stock, and rack up storage fees while customs resolves the discrepancy.

Common FBA categories and where they classify

These are typical 6-digit subheadings for popular FBA products. Treat them as starting points, not final answers: the exact code turns on material and construction, so confirm each one with a lookup before you file.

How to classify an FBA shipment

List every SKU. Pull the description for each product in the inbound shipment. Note material, function, and intended use. "Knitted cotton t-shirt" beats "shirt".
Classify each one. Run the descriptions through HS Mate. You get the 6-digit code plus the chapter and heading it sits under, with the reasoning.
Put the code on the commercial invoice. Give your forwarder the codes instead of letting them guess. Customs clears at the right rate, and there are no surprises at the border.

On the €99/mo business plan you can bulk-classify your whole catalog over the API, so every new SKU has a code before it ever ships. See pricing.

Already shipped? Check past imports for a refund

If you paid Section 301 or IEEPA tariffs on FBA imports in 2024 or 2025, some of those payments may be recoverable after recent court rulings. HS Mate audits your past shipments, finds the refund opportunities, and files the paperwork. We charge 15% contingency, so if CBP does not pay you, neither do we. See our duty refund audit.
