This guide supports Extramet’s U.S. tungsten carbide manufacturer by answering the practical engineering and purchasing questions that usually come before an RFQ.
Quick Answer
- Quality documentation should be stated before quoting.
- Material certs and dimensional reports answer different questions.
- Traceability requirements can affect process planning and lead time.
| Document | What it supports | When to request |
|---|---|---|
| Material cert | Grade and material traceability | Regulated or critical applications |
| Inspection report | Dimensional conformance | Tight-tolerance finished parts |
| ISO certificate | Quality system verification | Supplier qualification |
Why documentation matters
Carbide components often live inside high-value tooling, production equipment, and regulated supply chains. Documentation gives buyers evidence that material, dimensions, and processes match the purchase requirements.
Do not wait until shipment
If a buyer needs certs, inspection reports, or customer-specific QA paperwork, those needs should be listed on the RFQ and purchase order. Late documentation requests can delay shipment.
Inspection and technical review
For tight-tolerance carbide parts, inspection planning is part of manufacturability. Define datums, critical dimensions, surface finish, and reporting format early.
What to Include in an RFQ
- required certs
- inspection report format
- critical dimensions
- traceability or customer-specific QA clauses

Frequently Asked Questions
Is ISO certification the same as a part inspection report?
No. ISO relates to the quality management system. Inspection reports document measured part dimensions or characteristics.
Should cert requirements be on the PO?
Yes. Put documentation requirements on the RFQ and purchase order.
Can documentation affect price?
It can, because reporting, inspection, and traceability add process time.
