What is an HTS code?

An HTS code (Harmonized Tariff Schedule of the United States, or HTSUS) is the 10-digit code the US uses to set the import duty on a product. It is maintained by the US International Trade Commission. The first six digits are the international Harmonized System (HS) code used worldwide; the US adds four more digits for its own tariff and statistical detail.

HTS code vs HS code: the difference

People use the terms interchangeably, but they are not the same thing, and on a US customs entry the difference matters:

  • HS code (6 digits). The global base, identical in 200+ countries. Example: 8471.30 for portable computers.
  • HTS code (10 digits). The US version: the same 6-digit base plus 4 US-specific digits. Example: 8471.30.0100. This is what CBP wants on your entry, and it determines your exact duty rate.

Every valid HTS code starts with a valid HS code. So the fastest way to your HTS code is to nail the 6-digit base first, then add the US extension. That is exactly what the tool above does for the base, with the reasoning shown.

How to read a 10-digit HTS code

Take 8471.30.0100:

  • 84: chapter (machinery and mechanical appliances)
  • 8471: heading (automatic data-processing machines)
  • 8471.30: international HS subheading (portable, under 10 kg)
  • 8471.30.01: US tariff line (sets the duty rate)
  • 8471.30.0100: US statistical suffix (for trade data)

How to find your HTS code

  1. Describe your product in the box above. Include the material, what it does, and how it is used. The finished article is what gets classified.
  2. Get the 6-digit HS base with an audit-trail explanation: which chapter, which heading, and why this code over the alternatives.
  3. Add the US extension. Browse the matching chapter and heading to find your full 10-digit HTSUS line, or get a written report and have your broker confirm the last four digits.

Why your HTS code matters more in 2026

  1. The de minimis exemption ended. Through August 2025, US imports under $800 were duty-free. That is gone. Every parcel now needs a declared HTS code, including Amazon FBA replenishment and Shopify orders. See what changed.
  2. Tariffs spiked. Effective US rates on common categories rose sharply in 2024-2025, so the cost of a wrong code went from annoying to serious.
  3. Some tariffs are being refunded. The Supreme Court struck down the 2025 IEEPA tariffs and CBP is refunding them now. The Section 301 China tariffs were not struck down and remain in force. If you imported in 2025, check your IEEPA refund.

Paid US tariffs in 2024 or 2025?

The Supreme Court struck down the 2025 IEEPA tariffs and CBP is refunding them now. You may be owed money back. The audit is free and we only get paid when you do.
