Why this affects your quote
Anti-dumping and related trade measures apply to specific products from specific origins, defined by classification and product description. Steel, fabricated metal and certain finished metal goods are categories where such measures are encountered in Brazil. If a supplier describes your part loosely for export and your broker classifies it differently on arrival, the applicable measures can change — and so can the landed cost.
That is why the question belongs at the enquiry stage, not at the port. This page is about the documents and checks a buyer can control in China; it does not list measures, rates or case numbers, and it is not legal advice.
Documents to request before production
| Document | What it tells you |
|---|---|
| Full technical description and drawing | Material, process, dimensions, finish and intended use — the basis of classification. |
| Material certificate / mill certificate | The actual grade and origin of the raw material, traceable to the batch. |
| Manufacturing process statement | Where the substantial transformation happened and which factory did it. |
| Declaration of origin naming the producer | The legal entity behind the goods, not just the trading company on the invoice. |
| Business licence and registered scope | That the named producer is legally permitted to make the product. |
| Test report for the exact model | That the assessed product is the one being shipped. |
A supplier that cannot produce a material certificate or name the mill is not necessarily dishonest, but it is not ready for a shipment where classification and origin will be examined. How we verify a factory.
The link to classification
Classification follows the real product. A bracket, a stamped component and a machined assembly may be described by a factory as “metal parts” but fall under different tariff lines. Ask your broker to confirm the NCM against the drawing and the material certificate, then make sure the commercial invoice, packing list and origin evidence all use that description. Our drawing and tolerance notes and quote cost breakdown explain why a precise specification is also a commercial control.

When to get written advice
If the product sits near a category boundary, if the supplier changes the material or process, or if the broker flags a possible measure, get a written opinion before the order is placed. Do not rely on a freight forwarder’s blog, a forum answer or a supplier’s assurance that “this code is fine”. Keep the written advice with the order file, alongside the approved sample and the document set.
Where this meets our metal parts work
Custom metal parts, CNC machined components and fabricated assemblies are the most mature category on this site, and the one where documentation discipline pays off most. Start with the custom metal parts guide, the sourcing agent page and the landed cost guide. The RFQ checklist shows how to put material, process and documentation requirements into the enquiry itself.
