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
