HS Codes Explained (Plain English)

If you import products, your HS code affects duty rates, restrictions, and what paperwork you need. This guide shows how HS classification works — and what info you should collect before you guess.

What is an HS code?

HS stands for Harmonized System. It’s a standardized way governments classify traded products. Your HS code helps determine the duty rate, taxes, and whether your item needs permits or special controls.

How HS codes are structured (simple)

  • First 2 digits: Chapter (broad product category)
  • First 4 digits: Heading (more specific group)
  • First 6 digits: Subheading (internationally standardized)
  • Beyond 6 digits: Country-specific extensions (varies by country)

Why small details change the HS code

Classification is based on what the product is, what it’s made of, and how it’s used — not how it’s marketed.

The 10 details that matter most

  • Materials: plastic vs metal vs textile, % composition
  • Function: what it does (primary purpose)
  • How it works: manual, electric, battery, heated, etc.
  • End use: consumer, industrial, medical, food-contact
  • Size/capacity: wattage, volume, dimensions can matter
  • Set vs single item: sold as kit or individual product
  • Part vs complete good: replacement part or finished item
  • Brand/model: sometimes helps identify technical function
  • Packaging/retail presentation: can matter for “sets”
  • Country rules: each import country may add extra digits

Common HS code mistakes that cost money

  • Choosing a code based on a supplier’s listing without verifying details
  • Using a “closest match” keyword instead of describing function/materials
  • Not separating parts vs complete goods
  • Ignoring restrictions (food-contact, medical, batteries, chemicals)
  • Assuming the same HS code works for every import country
