Frequently Asked Questions
What is the HTSUS?
HTSUS means Harmonized Tariff Schedule of the United States. It is the US tariff classification system for imported goods and is used to determine the duty rate, reporting unit, and tariff programs that apply to a shipment.
What is an HTS code?
An HTS (Harmonized Tariff Schedule) code is a 10-digit classification number used by US Customs and Border Protection to identify imported goods and determine the applicable duty rate. The first 6 digits are standardized internationally, while the last 4 are US-specific.
How do I look up an HTS code?
Type a product description in the search box above. Our AI searches across 35,571 HTS codes and returns the best matches with full duty rates. You can also search by partial HTS number (e.g. '7304.19') or browse by chapter.
Are HTS codes the same as HS codes?
HS (Harmonized System) codes are the first 6 digits shared internationally. HTS codes are the US extension — 10 digits total. For US imports, you need the full 10-digit HTS code.
How do I find a 10-digit HTS code?
Start with a product description, identify the most likely HTS chapter, then compare headings and subheadings until you reach the 10-digit US statistical suffix. Material, use, construction, and country of origin can all affect the correct code.
What duty rates are shown with each HTS code?
Each result shows the MFN (Most Favored Nation) base rate plus any applicable overlays: Section 301 (China), Section 232 (steel/aluminum), Section 122 (temporary global surcharge), and the total estimated duty rate.
