About PMDTC HTS Lookup

Written by the PMDTC editorial teamLast reviewed August 19, 2026Editorial policy

PMDTC HTS Lookup is a free reference tool for the US Harmonized Tariff Schedule. It exists because the official schedule is a legally precise document that is genuinely difficult to read: 29,847 tariff lines published as nested PDFs and spreadsheets, where the wording of any single line only makes sense once you have read the categories above it.

Who publishes this

PMDTC HTS Lookup is published by PMDTC. We are not a customs broker, a freight forwarder, or a government agency, and we have no commercial relationship with any broker or carrier — nothing on this site is a paid placement or a lead-generation funnel. The site is maintained as a public reference: the data is the official USITC export, and the explanatory writing around it is ours.

You can reach us at hello@pmdtc.org or through the contact form. Corrections get priority over everything else in the inbox.

What the site does

  • Search by product or by code. Fuzzy matching across every official description and the resolved category path, so everyday wording finds the right line even when the tariff schedule uses different language.
  • Decode a code you were given. Paste a full or partial number and see the description, the duty columns, and what each pair of digits controls.
  • Estimate duty. A calculator that reads the published general and special rate text for a code and applies it to a declared customs value.
  • Show the hierarchy honestly. All 99 chapters are browsable as nested reference pages, and each of the 19,949 filing-ready 10-digit codes shows the parent line its duty rate is legally set at.

What it deliberately does not do

It does not classify goods for you. Classification is a legal determination that depends on the composition, function and condition of the specific article, and only CBP can settle it — through a binding ruling. It does not issue advice, it does not file entries, and it does not track antidumping, countervailing, Section 232 or Section 301 actions line by line — those change faster than a tariff revision and belong with your broker.

Data and currency

Every figure on the site comes from the USITC Harmonized Tariff Schedule, 2026 Basic Edition, Revision 16. The methodology page documents exactly how that export is processed, what we derive, and what we leave untouched. Our editorial policy covers review cadence and corrections.
