HTS Code Lookup: Search Tariff Codes, Duty Rates, and Section 301 Surcharges with AI
TL;DR
- Look up the USITC Harmonized Tariff Schedule live through the HTS Tariff MCP server — 99 chapters, roughly 12,000 classifiable lines — by keyword or HTS code.
- Returns general, special, and column-2 duty rates plus Section 301/232 surcharge cross-references, so import ops can estimate landed duty and sourcing-country differences before broker review.
- Not legal classification advice: a fast, traceable first pass that saves tab-hopping when someone asks what code and what duty apply to this product?
If you are responsible for imports, landed-cost estimates, product classification, or customs review, HTS lookup is not an academic exercise. A wrong code changes margin, delivery timing, and compliance risk.
The first question is usually simple: "What HTS code should we use for this product?" Then the real questions start. Is the description close enough? Is there a more specific subheading? What is the general duty rate? Does a Section 301 surcharge apply? Is the result reliable enough to quote from, or does it need broker review?
The HTS Tariff MCP server is built for that first-pass classification workflow. Your agent can search tariff entries, inspect the hierarchy, pull duty fields, notice surcharge references, and turn the result into a short explanation your team can actually use.
