How to Find Your HTS Code: 4 Methods That Actually Work

April 7, 2026 · 6 min read

Getting the wrong HTS code means overpaying duties or triggering a customs audit. Here are four ways to find the right one — from quick searches to legally binding rulings.

Method 1: Search Online (Fastest)

The fastest way to find your HTS code is to search by product name or HS number. Our free HTS Code Lookup searches 18,000+ codes from the official USITC database and shows duty rates instantly.

How to search effectively:

  • Start broad: search "shirt" not "men's long-sleeve cotton dress shirt"
  • Try the material: "cotton" or "polyester" often narrows results quickly
  • If you know the first 4-6 digits from your supplier, search by number
  • Review multiple results — the right code depends on material, use, and construction

Best for: Quick lookups, initial research, verifying supplier-provided codes.

Method 2: Browse the USITC Official Schedule

The US International Trade Commission publishes the official Harmonized Tariff Schedule at hts.usitc.gov. This is the legal reference that customs brokers and CBP use.

How to use it:

  1. Identify the correct chapter (e.g., Chapter 62 for clothing)
  2. Read the chapter notes — they contain critical classification rules
  3. Navigate to the heading (4 digits) that best describes your product
  4. Apply the General Rules of Interpretation (GRI) to find the subheading
  5. Drill down to the 8- or 10-digit statistical line

Best for: Complex products, situations where multiple codes could apply, understanding the legal basis for classification.

Method 3: Ask a Licensed Customs Broker

For high-value products or complex classifications, a licensed customs broker is worth the investment. They classify products professionally and take responsibility for the accuracy.

When to use a broker:

  • Product value exceeds $10,000 per shipment
  • Multiple possible HTS codes apply
  • Product is a combination of materials (e.g., leather and fabric)
  • You're importing for the first time
  • You've received a penalty notice or audit from CBP

Cost: Most brokers include classification as part of their entry filing fee ($75-200 per entry). Standalone classification consultations typically run $100-500.

Best for: First-time importers, high-value goods, regulated products.

Method 4: Request a Binding Ruling from CBP

For maximum certainty, you can request a formal classification ruling from US Customs and Border Protection. A binding ruling is legally binding — CBP must honor it at the port of entry.

How it works:

  1. Submit a ruling request via the CBP CROSS system (rulings.cbp.gov)
  2. Include detailed product description, photos, composition data, and intended use
  3. CBP reviews and issues a ruling (typically 30-90 days)
  4. The ruling is valid for 3+ years and applies to all ports

Best for: Ongoing imports of the same product, products where classification is disputed, products with AD/CVD exposure.

Common Classification Pitfalls

  • Don't rely solely on your supplier's code — Their HS code is for their country's tariff schedule. The first 6 digits should match, but verify the US-specific digits.
  • Material matters more than you think — A "cotton" blend with 51% polyester classifies as synthetic, which often has a higher duty rate.
  • Read the section and chapter notes — They override the plain text of headings and can change classification entirely.
  • Sets and kits have special rules — GRI 3 covers goods put up in sets. The classification follows the component that gives the set its essential character.
