HS classification for stamped and deep drawn parts
Buyers often treat HS classification for stamped parts as the supplier’s job. It is not. The importer declares the code, and the supplier’s only task is to describe the goods so accurately that you can defend the code. Get that description right and the rest follows.
| What the classifier asks | Why it changes the code | What we supply |
| What metal is it. | Base metal sets the chapter. | Grade and standard, as ordered. |
| Is it a finished article or a part. | A finished article and a loose part take different codes. | Drawing revision and function note. |
| What does it do in the end product. | A part of a machine can travel with the machine. | Where the part is fitted, in plain words. |
| Is it coated or plated. | A coating can move the goods. | Finish specification, stated separately. |
| How was it made. | Process rarely decides, and it can matter. | Process route: stamped or deep drawn. |
Material sets the chapter, and nothing else does
The Harmonized System is organised by material first. Steel parts begin in one place, aluminium parts in another, and copper parts somewhere else again. Therefore the grade matters before the shape does, and a drawing that names the grade saves an argument later.
However, the material only chooses the starting point. After that, the question is whether the part is a finished article in its own right or a part of something larger. That single distinction moves more classifications than any other.
Why the process usually does not decide
A stamped bracket and a machined bracket can land in the same heading when they are the same article. The system classifies what the thing is, not how someone made it. In practice, this surprises buyers who expect the process to drive the code.
Deep drawing is a good example. A deep drawn cup and a fabricated cup of the same metal and the same purpose can share a heading, even though the routes are completely different. Consequently, process detail belongs in the description and not in the code argument.
The description your broker needs
First, name the base metal and the grade, because that anchors the whole file. Second, say whether the part is sold on its own or as part of an assembly. Third, name the finish, since a plated part is not the same as a bare one.
Next, attach the drawing revision. Then add one plain sentence about what the part does, in the buyer’s own words rather than in shop language. Finally, state the process route, because that helps a broker understand the goods even when it does not change the heading. That single sentence often prevents a customs query several weeks later.
Compare that list against the records we keep for HS classification for stamped parts, which log the grade and the tolerance class on every job.
How to confirm the code, and who to ask
Three official routes exist, and each is free. You can read the tariff schedule itself, ask the customs authority for a written ruling, and check the destination union’s own database. For a US import, that means the schedule published by the United States International Trade Commission.
For an EU import, that means the union’s tariff database, which changes continuously. In addition, the World Customs Organization explains how the six-digit system is structured, which is useful when someone argues about the first four digits.
However, none of those routes replaces a ruling on your own goods. When the value at stake is real, ask for one. Our role is to give you the facts the request needs.
What we write on the invoice
We describe the goods in the same words on every shipment, because a stable description is easier to defend than a fresh one. Furthermore, we keep the invoice description aligned with the drawing revision, so the two never contradict each other.
We also state the material standard and the finish as separate fields. That helps your broker see which facts are which, rather than reading one long sentence. Our quality system holds ISO 9001:2015 certification, and we keep the records behind each line. You can also ask us for a short technical note on any part, written for a broker rather than for a shop floor.
Frequently asked questions
These are the questions importers ask most often about this classification split.
Will you put an HS code on our invoice?
We will state the goods description and the material facts that a code builds on. The declared code belongs to the importer, so we will not present a guess as a determination.
Does stamping change the classification?
Rarely on its own. The system classifies what the article is, and a stamped bracket can share a heading with a machined one. Process detail supports the description without deciding the heading.
Where do we get an authoritative answer?
Ask the customs authority in the country of import for a written ruling. That is the only route that binds the authority to an answer for your goods.
What if our part is assembled into a machine?
Then two readings are possible, and the function decides between them. Tell us where the part is fitted, and we will describe it in those terms on the invoice.
