HS code vs. U.S. HTS code: classify before you calculate
A supplier’s HS code can be a research clue, but U.S. import duties use the applicable U.S. HTS classification. The first six digits follow the international HS structure; U.S. subdivisions and statistical digits require their own review. Search the current schedule, read the legal text and notes, and resolve ambiguity before calculating.
Understand which digits travel
| Level | Use | Practical limit |
|---|---|---|
| HS six-digit base | Internationally harmonized starting point | Does not resolve U.S. subdivisions |
| U.S. HTS ten-digit line | U.S. import tariff/statistical reporting | Requires product facts, notes and applicable edition |
| Supplier’s foreign extension | May describe its own country’s reporting | Do not copy into a U.S. entry |
Classify from the product, not the keyword
For a hypothetical electronic device, collect its function, components and technical sheet first. Search likely HTS headings by description, then read the heading text, legal section and chapter notes, and the relevant rules of interpretation. A keyword hit can point to several competing headings; compare what each legally covers. Do not use this exercise to infer any actual television code.
- Match the exact goods and configuration at import, including sets or accessories.
- Check the HTS edition relevant to the planned entry date and any Chapter 99 provisions separately.
- Keep a short written rationale and source links; if two headings remain plausible, consult CROSS or request expert/ruling guidance.
Validate the code before entering it
Ask the supplier what product facts support its code, not merely for the digits. A customs broker can review the U.S. classification and evidence when the value of an error is material. Separately investigate additional duties and AD/CVD: a correct ordinary HTS line does not prove those are absent.
Assumptions and limits
Assumptions
- You have a technical product description and are classifying for a U.S. import, not an export declaration in another country.
Costs and duties not included
- No product is classified in this article; a search result is not a binding ruling.
Prepare your own estimate
Use your shipment details to open the existing calculator.
Use digits and a dot, with up to two decimals (for example, 1200.50).
Opening the calculator prepares these inputs. Only pressing Calculate uses a calculation from your plan.
You will need to select the correct HTS code in the calculator before it can estimate duties.
Common questions
Can I use the Chinese supplier’s ten-digit code?
Use it as a lead only. U.S. subdivisions must be validated against the U.S. HTS and the actual goods.
Does finding a code settle all duties?
No. Review entry date, origin, Chapter 99, other applicable measures and separate AD/CVD scope.
