For customs brokers and importers
Every Chapter 99 duty code for any HTS number. In seconds.
Paste your HTS numbers, pick the country of origin, and get every Section 301 and Section 232 heading, forced-labour provision, exemption and PGA requirement that applies — with the total additional duty rate worked out for you.
Tariff layers change faster than anyone can track by hand
CBP publishes constantly
New CSMS bulletins revise headings, add exemptions and carve out countries. A list you exported last month is already behind.
One line can hit five programmes
A single HTS number can carry Section 301, a Section 232 metals heading, a forced-labour provision and an exemption at the same time.
A missed code is a correction
Filing without the right Chapter 99 heading means post-summary corrections, penalties and delays that land on you.
How it works
Paste your codes
Up to ten at a time, in any format. Dots optional, and a leading zero dropped by a spreadsheet is restored automatically.
Choose the origin
Country of origin decides which headings actually apply, including the note 52 blanket headings and per-country carve-outs.
Read the table
One row per code, one column per programme, every Chapter 99 heading listed with its rate and the total additional duty.

Questions
- How current is the data?
- The dataset tracks CBP's CSMS bulletins and Federal Register notices and is updated as they are published. Every heading records the source it came from.
- What happens when I cancel?
- Automatic billing stops immediately and you keep access until the end of the period you have already paid for. There are no partial refunds.
- Can I look up as much as I like?
- The service is built for verifying and filing entries, not for bulk export, so fair-use limits apply — see the Terms of Service. Normal broker workloads sit comfortably inside them.
- Is this a substitute for the HTSUS?
- No. It is a research tool that gets you to the right headings quickly. Always verify against the official HTSUS and CBP guidance before you file.
