What is an HTS Code?

An HTS (Harmonized Tariff Schedule) code is a standardized numerical code used to classify every product imported into the United States. The code determines:

  • The duty rate you'll pay
  • Whether any special tariffs apply (like Section 301)
  • Statistical tracking of trade flows
  • Eligibility for trade agreement preferential rates

Understanding HTS Code Structure

HTS codes follow a hierarchical structure:

  • Chapters (2 digits): Broad product categories (e.g., Chapter 85 = Electrical Machinery)
  • Headings (4 digits): More specific groupings (e.g., 8517 = Telephone sets)
  • Subheadings (6 digits): International standard level (e.g., 8517.13 = Smartphones)
  • US-specific (8-10 digits): The full statistical suffix (e.g., 8517.13.00.00)

The first 6 digits are standardized worldwide under the Harmonized System (HS). The remaining digits are US-specific.

Step 1: Identify What Your Product IS

Before searching for a code, clearly define:

  • What is the product made of? (material composition matters)
  • What is its primary function?
  • Is it a finished product, component, or raw material?
  • How is it used?

Step 2: Start with the Section and Chapter

The HTS is organized into 21 Sections and 97 Chapters. Start broad:

  • Animal products → Sections I-II (Chapters 1-14)
  • Chemicals → Section VI (Chapters 28-38)
  • Textiles → Section XI (Chapters 50-63)
  • Machinery → Section XVI (Chapters 84-85)
  • Electronics → Chapter 85

Step 3: Narrow Down to Heading and Subheading

Within your chapter, read through the headings. HTS classification follows the General Rules of Interpretation (GRI):

  • GRI 1: Classification is determined first by the terms of the headings and section/chapter notes
  • GRI 2: Incomplete or unfinished articles are classified as the finished article if they have its essential character
  • GRI 3: When goods appear classifiable under two or more headings, use the most specific description

Step 4: Use Our Search Tool

Use the VatCheck HTS code search to quickly find codes by product description. Enter keywords describing your product and browse the results.

Step 5: Verify with CBP Ruling Letters

For high-value or ambiguous products, search CBP's CROSS (Customs Rulings Online Search System) database for binding rulings on similar products.

Common Mistakes to Avoid

  • Classifying by intended use alone: Material composition often takes precedence
  • Using a competitor's code without verification: Different products may look similar but classify differently
  • Ignoring chapter and section notes: These can override seemingly obvious classifications
  • Not updating codes: HTS codes change periodically

When to Get Professional Help

Consider hiring a licensed customs broker when:

  • Your product is valued over $100,000
  • Classification is ambiguous
  • You're importing regularly
  • Your product may be subject to anti-dumping or countervailing duties
