If you're importing goods into the United States, one of the first things you need is the correct HS code (Harmonized System code) for your product. This 6-digit international code determines your tariff rate, trade statistics classification, and customs documentation requirements.
What is an HS Code?
The Harmonized System is an international product classification maintained by the World Customs Organization (WCO). It covers over 5,000 commodity groups, each identified by a 6-digit code. Nearly every country in the world uses HS codes for customs and trade statistics.
In the U.S., HS codes are extended to 10 digits:
- HTS codes (Harmonized Tariff Schedule) — used for imports, determines duty rates
- Schedule B codes — used for exports, required for AES filings
Both share the same first 6 HS digits. The last 4 digits are U.S.-specific.
How HS Code Structure Works
HS codes follow a hierarchical structure:
- Chapter (2 digits) — Broadest category. Example: Chapter 09 = Coffee, Tea, Spices
- Heading (4 digits) — Narrows the category. Example: 0901 = Coffee
- Subheading (6 digits) — Specific product. Example: 090111 = Coffee, not roasted, not decaffeinated
Step-by-Step: Finding Your HS Code
1. Use Our Free HS Code Lookup Tool
The fastest way to find your code is our HS Code Lookup tool. Search by product name (like "coffee beans" or "steel pipes") or by a partial code number. Results show the code, description, and current U.S. import value.
2. Start Broad, Then Narrow Down
If you're not sure where to start, browse by HS chapter. Find the chapter that matches your product category, then drill into headings and subheadings.
3. Verify with the Official HTS
For binding classification rulings, always verify with the USITC HTS database. Our tool provides the 6-digit HS code — the full 10-digit HTS code includes tariff-specific detail.
Common Mistakes to Avoid
- Using the wrong level — A 4-digit heading is too broad for customs. You need at least 6 digits.
- Confusing HS and HTS — The 6-digit HS code is international. The 10-digit HTS code is U.S.-specific and includes the duty rate.
- Ignoring material composition — Many HS codes depend on what a product is made of, not just what it looks like.
- Not checking country-specific rates — The same HS code can have different duty rates depending on origin country. Use our Tariff Rate Lookup to check.
What to Do After Finding Your Code
Once you have your HS code, you can:
- Look up the effective duty rate for your product
- Estimate your total landed cost including duties, freight, and insurance
- Check trade balance data by country for your product category
- Browse trade opportunities in related product categories
