Frequently Asked Questions
What is the Harmonized Tariff Schedule?
The Harmonized Tariff Schedule of the United States (HTSUS) is the official classification system used by US Customs and Border Protection (CBP) to determine the duty rate on every product imported into the United States. It contains approximately 35,571 individual tariff lines organized into 99 chapters.
What is HTSUS?
HTSUS is the abbreviation for the Harmonized Tariff Schedule of the United States. It is the US version of the global Harmonized System and is used for import classification, duty rates, reporting units, special tariff programs, and legal notes.
How is the HTS organized?
The HTS is organized into 22 sections and 99 chapters, progressing from raw materials (animals, plants, minerals) through processed goods (chemicals, textiles, metals) to finished products (machinery, electronics, vehicles). Each chapter contains headings (4-digit), subheadings (6-digit), and statistical suffixes (8-10 digit) for increasingly specific product descriptions.
Is an HS code the same as an HTS code?
No. An HS code is the international 6-digit product classification. A US HTS code extends that HS code to 10 digits for US import duty rates, statistical reporting, and tariff programs.
How do I find a 10-digit HTS code?
Start with the product's material, use, construction, and function, then browse the relevant HTS chapter from heading to subheading to the 10-digit statistical suffix. For a faster first pass, use the HTS code lookup and verify the final classification before entry.
Who maintains the HTS?
The US International Trade Commission (USITC) publishes and maintains the HTS. The underlying 6-digit Harmonized System (HS) is maintained by the World Customs Organization (WCO) and used by over 180 countries. The US adds its own 4 additional digits for statistical and duty rate purposes.
How often is the HTS updated?
The HTS is updated periodically through presidential proclamations, trade legislation, and USITC revisions. Major updates include new tariff programs (like Section 301 or 232), trade agreement implementations, and the HS revision cycle (every 5 years). We update our database within 24 hours of any change.
What is the difference between HTS and Schedule B codes?
HTS codes are used for imports. Schedule B codes are used for exports. They share the same first 6 digits (the international HS code), but the remaining digits differ. If you're importing, use HTS codes. If you're exporting, use Schedule B codes from the Census Bureau.
