HTS Code Lookup: How to Find Your Harmonized Tariff Code in 2026

Every product imported into the US needs a Harmonized Tariff Schedule (HTS) code. Get the wrong code and you'll pay the wrong duty rate — sometimes thousands of dollars too much. This guide shows you exactly how to find the right code and check your current duty rate.

What Is an HTS Code?

The Harmonized Tariff Schedule (HTS) is the US version of the international Harmonized System (HS). It classifies every importable product with a numeric code that determines:

How HTS Codes Are Structured

DigitsLevelExample (Ceramic Tiles)
First 2Chapter69 — Ceramic products
First 4Heading6907 — Ceramic flags, tiles
First 6Subheading (international)6907.21 — Tiles, absorption ≤0.5%
8-10US-specific tariff line6907.21.1010 — Specific tile type with duty rate

The first 6 digits are internationally standardized. The last 4 digits are US-specific and determine your exact duty rate.

How to Look Up Your HTS Code: Step by Step

Step 1: Start broad — identify the chapter

The HTS has 99 chapters organized by material/type. Common ones: Chapter 39 (plastics), 61-62 (clothing), 73 (steel), 84-85 (machinery/electronics), 94 (furniture).

Step 2: Narrow to the heading (4 digits)

Within your chapter, find the 4-digit heading that best describes your product's material and function.

Step 3: Find the subheading (6 digits)

The 6-digit subheading adds specificity — size, composition, processing method, etc.

Step 4: Get the full HTS number (8-10 digits)

This is the US-specific tariff line with the exact duty rate. Use our HTS browser to find it, or search the official USITC database.

⚠️ Pro Tip: Don't guess your HTS code. An incorrect classification can result in penalties up to 4x the duty owed. When in doubt, file a binding ruling request with CBP — it's free and takes 30 days.

Common HTS Classification Mistakes

  1. Classifying by use instead of material. HTS classifies primarily by what something IS, not what it's FOR. A plastic phone case is classified under plastics (Chapter 39), not phones (Chapter 85).
  2. Using the wrong country of origin. Duty rates vary by country. USMCA (Mexico/Canada) often means 0% duty. China usually means Section 301 surcharges.
  3. Ignoring sets and kits. A gift set with multiple items follows special classification rules (General Rule of Interpretation 3).
  4. Not checking for updates. HTS codes change annually. A code valid in 2025 might be split or renumbered in 2026.

Frequently Asked Questions

How many digits is an HTS code?

US HTS codes are 8-10 digits. The first 6 are internationally standardized (HS code). The last 2-4 are US-specific and determine your exact duty rate.

What's the difference between HS code and HTS code?

HS (Harmonized System) is the international 6-digit standard used by 200+ countries. HTS (Harmonized Tariff Schedule) is the US-specific version that adds 2-4 more digits for duty rate determination. The first 6 digits are the same.

Can I get fined for using the wrong HTS code?

Yes. CBP can impose penalties of up to 4x the duty owed for negligent misclassification, and up to 8x for fraud. They can also seize goods. If you're unsure, request a free binding ruling from CBP.

How do I find the duty rate for my HTS code?

Once you have the 8-10 digit HTS code, look up the "General" duty rate column. This is the rate for most countries. "Special" rates may apply if there's a free trade agreement. Check our HTS browser for the easiest lookup.
