Common questions

What is the HS code for air purifiers?

Products described as air purifiers are usually classified under HS heading 8421, subheading 8421.39. Confirm the full national code in the importing country's tariff.

Is the HS code the same in every country?

The first 6 digits are the same in every country that uses HS 2022, and national codes are built on them: the EU's CN, the US HTS, India's ITC-HS and HSN codes and Brazil's NCM all start with these digits. Each country adds its own digits (usually to 8 or 10) and sets the duty rate, so check the destination country's tariff.

What if my product is different?

Materials, function and how the product is put up can change the heading. Search your own description in the HS code lookup, read the chapter notes, and ask a customs broker or the customs authority for a ruling when in doubt.
