How to find the right HS code for your product

Classify in three passes: narrow the product to a heading in the official US HTS (hts.usitc.gov), search CBP’s CROSS database for binding rulings on genuinely similar products, then confirm the line with your customs broker before the first entry. The GSS (General Rules of Interpretation) decide close calls — function beats marketing names, which is why a “dog toy” can file under the toy heading and a “kitchen scale” under weighing machinery.

Browse typical codes by product

Pass 1 — narrow it in the official HTS

Start at hts.usitc.gov and search by plausible material words: the HTS is organized by material and function (plastics 39, textiles 61–63, ceramics 69, toys 95).
Read the chapter and heading notes: they exclude and redirect more often than beginners expect (e.g. many sports goods live outside 9506).
Land on a 10-digit statistical line and note its General duty rate — that is your MFN.

Pass 2 — verify with CROSS rulings

CBP’s CROSS database contains thousands of binding classification rulings. Search for your product described the way CBP would describe it (material, function, use — not brand names), and read two or three rulings for products genuinely like yours. If rulings cluster on one line, you have your answer; if they split, the distinguishing feature in the rulings tells you which side yours falls on.

Pass 3 — confirm with your broker

Give the broker the invoice, spec sheet, and product photos — classification is a service they perform as part of entry.
For high-volume or high-duty-rate products, a binding ruling request to CBP costs nothing and pins the classification.
Treat supplier-supplied HS codes as hints: factories guess, and the importer of record owns the classification, not them.

Shortcuts that misfire

Copying a competitor’s tariff code from their shipping records — their product may differ in a decisive detail.
Classifying by marketing name (“smart plug” files under 8536 apparatus, not under anything with “smart” in it).
Assuming one code covers a mixed SKU: multi-packs and sets classify under GRI 3(b) by essential character, sometimes surprisingly.

Questions people ask

Is the HS code the same in every country?

The first six digits are internationally harmonized; everything after that is national. The US HTS adds four statistical digits; the UK and EU maintain their own 8–10 digit tariff lines. A code from your Chinese supplier is usually a 6–8 digit hint at best.

What happens if I classify wrong?

Undeclared duty gets collected with penalties; willful misclassification is where fines get serious. Honest mistakes are fixable — brokers file corrections and prior disclosures. The expensive version is years of entries at a wrong, lower rate discovered at audit.

Do I need a different code for every SKU?

You need the right line per product as customs sees it: materially identical colors share a line, a different material or function does not. Classification is per product, not per listing variant.
