# Tariff & HS Code Duty Finder

Find candidate tariff codes and the duty for UK and US imports. It is free, with no sign-up and no key.

Also known as: Tariff Code Finder, HS Code Finder, HTS Duty Finder, Customs Code Lookup.

## What it does

Find an HS code, HTS code or customs code, and read the customs duty or import tax. Ask "what is the tariff code for a ceramic flower pot in the UK?", "what is the US duty on HTS 8507.60.00?" or "what duty applies to code 6914100000 from Vietnam in the UK?".

Tariff and HS Code Duty Finder reads the official schedules published by governments: the UK Trade Tariff (HM Revenue & Customs) and the US Harmonized Tariff Schedule (US International Trade Commission). Describe the product and it lists the codes whose descriptions match, with the headings above each one so a line that only says "Other" can be read in context. Give a code and it returns the description, the duty rate and, for the UK, the VAT rate, the preferential rate for the country the goods come from and other measures that apply. People also call it Tariff Code Finder.

Use it for a Harmonized System code, an HTS classification or a customs classification. Schedule B export codes often share the first digits of an HTS code, but this tool reads the import schedules, not the Schedule B export list. It does not search the EU TARIC list.

The codes it finds are candidates, not a classification. Which code is right depends on what the product is, what it is made of and how it is used, and customs decides. Check a candidate against the schedule's notes and confirm with customs or a licensed customs broker before you declare goods. For a binding answer, ask customs for a ruling.

The duty it shows is the rate in the schedule for that code. It does not add every extra duty, quota, anti-dumping measure or trade remedy. For the US, additional duties under chapter 99 of the schedule are not included. Rates change on published dates, so check the schedule on the day you ship.

It covers imports into the United Kingdom and the United States only. It stores nothing about you: answers are cached for up to 6 hours, and the only lasting record is a daily count of calls per tool.
