AI HS Code Finder
Every product that crosses a border carries a Harmonized System (HS) code — and that code drives the duty rate, the customs paperwork, and whether your shipment clears smoothly. Describe your product and our AI-assisted classification narrows it to the right chapter and candidate codes, with the reasoning shown. A human specialist then verifies the classification as part of your RFQ, before you rely on it.

How the finder works
1 · Describe the product
What it is, what it is made of, and what it does. Material and function — not the marketing name — decide the classification, so a precise description matters more than a part number alone.
2 · AI-assisted candidates
The classification logic walks the HS structure — section, chapter, heading, subheading — and produces candidate codes with the reasoning for each, so you can see why a code fits and where the close calls are.
3 · Human verification
AI suggestions are a starting point, not a ruling. Our sourcing team verifies the classification against your exact product and destination as part of your RFQ, and confirms it in writing before you order.
How HS codes are built
The HS is maintained by the World Customs Organization and used by 200+ economies. The first six digits are international; countries add their own digits for national rates and statistics.
| Level | Digits | Example — steel screws |
|---|---|---|
| Chapter | 2 | 73 — Articles of iron or steel |
| Heading | 4 | 7318 — Screws, bolts, nuts and similar articles of iron or steel |
| Subheading | 6 | 7318.15 — Other screws and bolts, whether or not with their nuts or washers |
| National extension | 8–10 | Added by each importing country for its own duty rates and statistics |
Examples on this page are educational. The correct code for a specific product depends on its exact material, function, and form — which is why step 3, human verification, exists.
Common products, typical headings
A few well-established classifications to show how the system thinks. Yours may differ — variants, materials, and added functions move products between headings.
| Product | Typical heading | Why |
|---|---|---|
| Lithium-ion batteries | 8507 | Electric accumulators are classified by function, including lithium-ion types |
| Cotton T-shirts | 6109 | Knitted apparel — fibre content and knit/woven construction decide the heading |
| Plastic enclosures & housings | 3926 | Other articles of plastics, when no more specific heading covers the item |
| Ball bearings | 8482 | Classified by mechanical function, whatever machine they end up in |
| LED lamps | 8539 | Electric lamps — light-source technology is specified at subheading level |
Mistakes that cost money
"Bracket" is not a classification. Customs classifies what an item is made of and what it does — two parts with the same name can sit in different chapters.
Exporters sometimes use their own country's extension or an approximate code. The importing country's customs makes the final call — and the importer carries the risk.
A change of material, a built-in battery, or an added function can move a product to a different heading with a different duty rate.
Honest limits
This finder provides classification guidance, not a binding ruling — only customs authorities issue those. Classifications and duty treatment can change, and the correct code depends on the exact product and destination. That is why every classification we work on is verified by our team and confirmed in writing with your RFQ before you commit to an order.
