Home / Glossary / What is an HTS Code | United States (HTS)

The Harmonized Tariff Schedule of the United States (HTSUS), also known as the HTS code system, is a standard for classifying goods imported into the United States.

The HTS code is important for setting import duty rates, ensuring shipments comply with customs rules, and handling trade paperwork. Each product brought into the U.S. needs the correct HTS code, which depends on its materials, description, and intended use.

HTS Code Structure for Tariff Classification

The HTS system is a 10-digit tariff classification code system used to categorize imported products in detail.

HTS Code Breakdown:

  • Chapter (2 digits): Broad product category (e.g., textiles, machinery, chemicals)
  • Heading (4 digits): Specific product group within a chapter
  • Subheading (6 digits): International harmonized classification level
  • U.S. tariff code (8–10 digits): Final level used for import duty calculation in the United States

HTS code 0902.10.1015 example :

HTS Code Segment What it Means Example Description
09 Chapter Coffee, tea, maté and spices
0902 Heading Tea, whether or not flavored
0902.10 Subheading Green tea (not fermented) in immediate packings of a content not exceeding 3 kg
0902.10.10 Subheading (e.g. Flavored) – establishes the U.S. customs duty rate
0902.10.1015 Subheading (e.g. Certified Organic) – provides additional statistical information

The first six digits are international and consistent across most countries. The last four digits are U.S.-specific and determine duty rates and trade treatment.

What Is a HTS Number Used For?

HTS numbers are used to describe goods brought into the United States from other countries. The HTS number helps customs officials find goods, determine the duties to charge, and ensure that U.S. import rules are followed.

HTS numbers are used by importers, customs brokers, freight forwarders, and government agencies to correctly process international shipments and determine their costs.

1. Determining Import Duty Rates

HTS numbers help determine the import fees and taxes for a product. Customs officers use the tariff rates for each category to figure out how much duty is owed on imported goods.

2. Customs Clearance

Products entering the U.S. must have the correct HTS code before Customs will allow them in. Using the right code helps you avoid delays, extra inspections, and fines.

3. Trade Compliance

Importers use HTS numbers to comply with U.S. trade laws and regulations. The correct classification makes sure your goods meet all requirements, limits, and reporting needs for imports.

4. Identifying Trade Agreement Benefits

Some free trade agreements or special programs lower or remove duties on certain goods. If your shipment qualifies, the HTS number will show this benefit.

5. Import Documentation and Reporting

Many import documents, such as customs reports and entry forms, require HTS numbers. In international trade, these numbers make it easy to identify goods.

6. Trade Statistics and Market Analysis

The government uses HTS codes to track imports, study trade trends, and create U.S. trade data. Companies rely on this information to explore markets and find new suppliers.
Why Accurate HTS Classification Matters

Using the wrong HTS number can lead to:

  • Incorrect duty payments
  • Customs delays and examinations
  • Fines and penalties
  • Compliance issues with U.S. Customs
  • Missed opportunities for duty savings

For this reason, importers should carefully verify the correct HTS classification for every product they bring into the United States.

How to Look Up U.S. HTS Codes

Knowing how to determine the correct U.S. HTS code is crucial for accurate import and export declarations. Several resources can aid in this process.

  • Online Databases: The U.S. International Trade Commission (USITC) website offers a comprehensive HTS code search tool. Additionally, the U.S. Customs and Border Protection (CBP) website provides resources and rulings that can assist in code determination.
  • Customs Brokers: For complex classifications, consulting a licensed customs broker is highly recommended. These experts possess in-depth knowledge of HTS codes for shipping and can provide professional guidance.
  • Product Descriptions & Technical Specifications: Detailed product descriptions, technical specifications, and manufacturer information can offer valuable clues for accurate classification.
  • CBP rulings: The CBP website provides a database of rulings. Reviewing these rulings can provide clarification on how similar products have previously been classified.
