Sourcing IVD Raw Materials Without a GMP Certificate

Not every supplier holds GMP. These are the questions that separate a capable raw-material supplier from one whose paperwork will not hold up.

Understand What You Are Buying

Many suppliers of research and IVD-development raw materials do not hold GMP manufacturing certification, and the absence of GMP is not by itself disqualifying. GMP status describes a manufacturing framework, not the quality of a specific lot. What matters is whether the material is fit for purpose and whether its quality can be demonstrated and maintained. Check the stated intended use, the release testing and the lot-to-lot consistency. A clear answer about limitations is more useful than a vague assurance of quality. A supplier who can describe the process clearly is often more informative than a certificate alone.

Questions to Ask Before Ordering

Ask what the material is intended for, whether it is produced under any formal quality system, and how lot release is defined. Ask how identity is confirmed and which method is used for purity. Ask whether a Certificate of Analysis accompanies each lot and what it contains. Ask how changes to the manufacturing process are communicated, and whether historical lot data or retention samples are held. Ask about stability data and the recommended storage and shipping conditions. The answers show how well the material is controlled.

What Documentation Should Accompany the Material

A practical pack includes a lot-specific Certificate of Analysis, a material safety data sheet where applicable, and a datasheet describing handling, storage and reconstitution. For cross-border shipment, documents such as a commercial invoice, packing list and certificate of origin may also be required. Confirm before ordering which documents the supplier can provide and in which format, because obtaining them after dispatch is slow. Treat documentation as part of the product specification rather than an afterthought.
