Find the HTS code. Then calculate the duty that applies now.
Search the current U.S. tariff schedule by code or product description, review the complete statistical suffix, and carry the result into an origin- and date-aware duty calculation.
Data note: The Trade Lab tariff service is currently versioned to 2026HTSRev13. The official USITC schedule remains the filing authority; always use the revision and legal measures effective on the entry date.
A defensible lookup workflow
A code match is the beginning of the analysis
Classification, origin, and entry facts work together. Treating a keyword match as a final rate is how outdated or incomplete duty estimates happen.
02
Confirm the legal text
Resolve the full 10-digit suffix and check the General Rules of Interpretation plus applicable Section and Chapter notes.

Frequently asked questions
What is an HTS code?
An HTS code is the U.S. 10-digit tariff classification used for customs reporting and duty treatment. The first six digits follow the international Harmonized System; the remaining digits are U.S.-specific.
Is an HTS search result a final classification?
No. A search result is a starting point. Final classification can depend on composition, function, principal use, condition as imported, General Rules of Interpretation, and Section or Chapter notes. Confirm the complete 10-digit code before filing.
Does one HTS code always have one duty rate?
No. The base rate is only one part of the analysis. Origin, entry date, trade-program claims, product scope, exclusions, and Chapter 99 measures can change the result.
How are current Section 301 duties handled?
Section 301 is no longer a China-only analysis. Current actions can produce an additive rate, an MFN-plus-Section 301 ceiling, or an exemption. The exact result must be resolved from the HTS code, origin, entry date, and applicable program data.
