How to Classify Products for Customs (HS Code Classification)
"How do I classify my product?" is one of the most common questions from new importers and exporters — get the HS code wrong and you risk the wrong duty rate, delayed clearance, or even penalties.
Start with what the product is, not what it's for
Classification is based on the product's material composition and function, not its intended use. A cotton bag classified as "luggage" versus "textile article" depends on construction, not on what you plan to put in it.
Use the General Rules of Interpretation (GRI)
The Harmonized System has six General Rules that determine classification order: first look at the heading text and section/chapter notes; if goods could fit multiple headings, the most specific description wins; mixed or composite goods are classified by their essential character.
Work from chapter to heading to subheading
HS codes are hierarchical: a 2-digit chapter (broad category), a 4-digit heading (more specific group), and a 6-digit subheading (globally standardized). Countries then add further digits for national tariff and statistical purposes.
When in doubt, request a binding ruling
Most customs authorities offer binding tariff information (BTI) — an official, legally binding classification decision for your specific product, valid for a set period. This is the safest option for high-value or ambiguous products.
Frequently asked questions
Can two similar products have different HS codes?
Yes — small differences in material, function, or how a product is packaged/presented can genuinely change its classification and duty rate.
Who is responsible if my HS code is wrong?
The importer of record is ultimately responsible, even if a supplier or freight forwarder suggested the code — always verify classification independently for anything unusual or high-value.

Conclusion
Correct classification is a process, not a guess — start from what the product actually is, apply the General Rules in order, and request a binding ruling when the value or the ambiguity justifies it.
