About HS-Code.net: Who Makes It and How

HS-Code.net helps importers, sellers and freight forwarders find the right HS code for a product and see why it is right: the official tariff text, the duty from official data, and the customs rulings that classified similar goods.

Why this site exists

Most HS code lookups give you a code and nothing else. Codes copied from a supplier, an old spreadsheet or an AI chat answer are often outdated or simply do not exist, and a wrong code can mean the wrong duty, a held shipment or a penalty. We think a code is only useful if you can check it. So every guide shows its evidence and says plainly when the answer depends on facts only you know about your goods.

Who runs it

HS-Code.net is an independent project by Anders Lee, a developer who builds reference tools from official public data. It is not a customs broker, law firm or government service, and it is not affiliated with U.S. Customs and Border Protection, the U.S. International Trade Commission, HMRC or any other authority. The site is free to use and has no paid placements.

How guides are made

Questions come from the tariff, not from guesswork. Each guide asks only the questions that the legal text uses to separate similar goods: material, construction, use, who it is for.
Codes and rates come from official data. US codes and rates from the USITC Harmonized Tariff Schedule (currently Revision 22 (2026)), UK rates from the UK Trade Tariff and EU rates from the EU tariff as published in the UK Trade Tariff for Northern Ireland. Nobody types a rate by hand.
Rulings are quoted word for word. Where U.S. Customs has ruled on similar goods, the guide quotes the ruling and links to it. The build checks every quote against the ruling text and drops rulings that have been revoked or modified.
Checks run every day. A new tariff revision, a code that disappears or a quote that no longer matches stops the site from being rebuilt until it is fixed. Read the full method.

There are 23 product guides so far, and new ones are added every week, starting with the products people search for most.

What it is not

Only customs can classify your goods. The guides show the most likely code and the reasoning behind it; for certainty on an important shipment, ask a licensed customs broker or request a binding ruling from CBP or HMRC. The US rate shown is the base rate: extra duties under Chapter 99, such as Section 301 or 232, depend on the country of origin.

Corrections and contact

If you find a wrong code, rate or quote, email hi@hs-code.net with the page and what you found. A ruling number or a link to the official tariff helps us check it quickly. Corrections are listed on the methodology page with their date.

Tariff revision updates are posted on Bluesky. The same US schedule is available offline as the hts-lookup Python package and as a browser extension for Chrome, Edge and Firefox.
