HS Code Lookup for ecommerce imports
Find the right Harmonised System (HS) tariff code for any product you import. Wrong HS codes cause customs delays, surprise duty bills, and seizure — Forthsource's free lookup keeps your declarations clean.
TL;DR
An HS code (Harmonised System code) is the 6–10 digit international tariff code customs uses to classify your product, calculate import duty, and apply quotas. Forthsource's free HS code lookup matches plain-English product descriptions to the most likely chapter, heading, and 6-digit code, with a destination-country duty estimate so you know what to expect at customs before the container leaves the factory.
Why HS codes matter
An HS code is the 6-digit tariff classification used by every WTO customs authority. Country-specific 8 or 10 digit extensions add destination-level granularity. Use the wrong code and you can pay 15% duty on something that should have been 4%, get the shipment held at port, or trigger a customs audit.
How to read an HS code
- Chapter (2 digits) — broad product family, e.g. 61 = knitted apparel.
- Heading (4 digits) — narrower group, e.g. 6109 = T-shirts & vests.
- Subheading (6 digits) — specific product, e.g. 610910 = cotton t-shirts.
- National (8–10 digits) — country-specific extension, e.g. US HTS 6109.10.0040.
Once you have the code, plug it into the landed-cost calculator with the duty rate from your destination country's tariff schedule.
