What an HTS code is
Ten digits that decide what your goods cost to import. Chosen once, applied to every entry after, and expensive to have had wrong.

An HTS code is the ten-digit number that identifies your product in the Harmonized Tariff Schedule of the United States. It determines the duty treatment, whether trade remedies apply, and which other agencies take an interest. It is the single most consequential decision in an entry, and it is made before the goods ship.
Key takeaways
- The first six digits are international. The last four are American and decide duty.
- Classification follows what the article is, not what the invoice calls it.
- A supplier's code is a starting point, never an answer.
- The same code applies to every subsequent entry, so an error compounds.
- Trade remedy exposure is triggered by the code and the origin together.
What the code actually describes
Classification asks what the thing is: what it is made of, what it does, and how it is presented at the border. It does not ask what it is called, what it will be used for after import, or what your purchase order says.
This is why two products that look identical in a catalogue can classify differently, and why a description like 'accessories' or 'spare parts' on a commercial invoice is not enough to work from.
Why the supplier's code isn't enough
Suppliers routinely provide a six-digit code, and six digits are genuinely shared internationally. But the digits that set the United States duty rate are the seventh and eighth, and your supplier does not have them.
A code copied from a foreign document is a code chosen under a different country's rules for a different purpose. It may point at the right area. It is not a classification.
Where it gets expensive
The importer of record is responsible for the classification, not the supplier and not the freight forwarder. Where a code understates duty, the exposure is not limited to the shipment in front of you. It reaches back across entries already made.
Trade remedies raise the stakes further. Antidumping scope and additional tariff measures attach by code and origin together, and a product that falls inside scope can carry exposure exceeding the value of the goods.
How a ten-digit code is built
A supplier who gives you a six-digit code has given you a starting point, not an answer. The digits that decide duty are the ones they do not have.
How it works
-
01
Describe the article properly
Material, function, and how it arrives at the border.
-
02
Find the candidate headings
Usually more than one looks plausible.
-
03
Apply the rules in order
The classification rules resolve competing headings; preference does not.
-
04
Check origin against the code
Trade remedies attach to the pair, not to either alone.
-
05
Document the reasoning
So the same answer is defensible on the hundredth entry.
Common mistakes
- Using the supplier's code as given. It was chosen under different rules.
- Classifying by end use. The code follows what the article is at import.
- Choosing the lower rate where two headings fit. The rules decide, not the outcome.
- Treating it as a one-off. The code repeats on every entry that follows.
- Leaving it to the invoice description. 'Parts' is not a classification.
Questions
Is an HTS code the same as an HS code?
The first six digits are the international Harmonized System code. The full ten-digit HTS code is the United States version, and the extra digits are where the duty rate and the reporting detail live.
Who is responsible if the code is wrong?
The importer of record. Not the supplier, not the forwarder, and not the person who suggested the code. That responsibility is why the decision is worth making deliberately.
Can I get a binding answer in advance?
Yes. A binding ruling can be requested before importing, which is worth doing where the classification is genuinely arguable and the volume is significant.
Does the code affect anything besides duty?
Yes. It signals which other agencies have an interest in the shipment, and it is one half of what triggers trade remedy exposure. Origin is the other half.
