What Is an HTS Code? How to Find the Right One for Your Product

An HTS (Harmonized Tariff Schedule) code is a 10-digit number assigned to every product imported into the United States that determines the duty rate you'll pay. Getting the right HTS code is arguably the most consequential decision in importing — it affects not only how much you pay in duties (potentially thousands of dollars per shipment) but also whether your product requires licenses, quotas, or other regulatory controls. Yet misclassification is one of the most common compliance errors, accounting for a significant portion of CBP penalties each year.

Understanding HTS Code Structure

The HTS code is built in layers, each adding specificity:

• Chapters (2 digits) — The broadest category. There are 99 chapters organized by material or industry. Chapters 1-24 cover agriculture, 25-27 minerals, 28-38 chemicals, 39-40 plastics/rubber, 41-43 leather, 44-49 wood/paper, 50-63 textiles, 64-67 footwear, 68-71 stone/ceramic/glass, 72-83 metals, 84-85 machinery/electrical, 86-89 vehicles, 90-92 instruments, and 93-99 miscellaneous.
• Headings (4 digits) — Narrow the category. For example, Chapter 85 (Electrical machinery) contains Heading 8517 (Telephone apparatus, including smartphones).
• Subheadings (6 digits) — The internationally harmonized level. Every country uses the same first 6 digits. 8517.13 = smartphones specifically.
• US-specific (8 digits) — The statistical suffix added by the US. 8517.13.00 for smartphones.
• Full HTS (10 digits) — The reporting code. 8517.13.0000 is the complete code for cellular phones.

How to Find Your HTS Code

There are several methods, from free government tools to AI-powered solutions:

1. USITC HTS Search (hts.usitc.gov) — The official source. Search by keyword or browse chapters. Free but requires knowledge of classification rules.
2. CBP CROSS Database — Search past classification rulings. If CBP has ruled on a similar product, the same logic should apply to yours.
3. Schedule B Search (census.gov) — For export codes, which mirror HTS for the first 6 digits.
4. Camtom AI Classifier — Describe your product in plain language and get the correct HTS code in seconds, with confidence scoring and duty rate estimates.
5. Customs broker — Your broker classifies products as part of their service, but you as the importer of record are ultimately responsible for correct classification.

The General Rules of Interpretation (GRI)

When a product could fit under multiple HTS codes, the six General Rules of Interpretation (GRI) determine which one is correct:

• GRI 1 — Classification starts with the heading text and section/chapter notes. This is the starting point and handles most products.
• GRI 2(a) — Incomplete or unfinished articles are classified as the finished article if they have the essential character. A car without an engine is still classified as a car.
• GRI 2(b) — Mixtures and combinations of materials are classified by their essential character, or by the material that gives the product its primary function.
• GRI 3 — When two or more headings could apply, the most specific heading wins (GRI 3a). If equally specific, the heading for the material giving essential character wins (GRI 3b). If still tied, the last heading in numerical order wins (GRI 3c).
• GRI 4 — Products with no comparable heading are classified under the heading for the most similar goods.
• GRI 5 — Rules for containers and packing materials.
• GRI 6 — Classification within a heading follows the same rules at the subheading level.

Common HTS Classification Mistakes

• Classifying by use instead of material — The HTS generally classifies by what a product IS, not what it's used FOR. A steel shelf bracket is classified under iron/steel articles, not under furniture.
• Ignoring Section and Chapter Notes — These notes override heading text. Always read them first.
• Using foreign HTS codes — Your Chinese supplier's HS code may not translate directly to a US HTS code at the 8- and 10-digit level.
• Not updating classifications — HTS codes change annually. The USITC publishes revisions every year effective January 1.
• Relying solely on product description — Two products with similar descriptions ("plastic container") can have very different HTS codes depending on size, material composition, or intended commercial use.

When to Request a Binding Ruling

A binding ruling from CBP gives you legal certainty about your product's HTS classification. Request one when: the duty rate difference between possible codes is significant, your product is novel or doesn't clearly fit one category, you've received inconsistent classifications from different ports, or you want protection from penalties in case of a future audit. Submit a ruling request through CBP's eRulings system at erulings.cbp.gov. Include photos, technical specifications, and material composition. Rulings typically take 30-120 days and are legally binding on CBP.
