Certificate of Analysis and Documentation
A certificate of analysis (CoA) is a document confirming that a specific batch of a raw material meets its agreed specification, listing the tested parameters and the results for that batch. Indock confirms a CoA, the specification sheet, and supporting batch records per shipment, checking each against your spec before the material ships, so you receive a verified input rather than buying on trust.
What a certificate of analysis contains
A CoA ties a physical batch to a documented set of results. Typical contents include:
- Material identity and grade
- Tested parameters such as purity, assay, particle size, or composition
- The result for each parameter against the specification
- A batch or lot reference you can trace back
What Indock confirms per shipment
We do not just pass paperwork through. For every shipment we confirm:
- Certificate of analysis (CoA): the batch meets its specification on tested parameters
- Specification sheet: the agreed grade and properties for the material
- Batch or mill records: for metals, a mill test report per heat; for chemicals, a safety data sheet alongside the CoA
Each document is checked against your spec, not just collected. The same standard applies whether you source metals and alloys, industrial chemicals, or minerals.
Why lot-to-lot consistency matters
Raw materials are only as reliable as the batch in front of you. A material that meets spec on one order and drifts on the next can change how your product performs and force you to re-qualify the input. Confirming documentation per shipment keeps each lot inside the spec you approved, which is what lets you stand behind your own product and keep your process stable. It connects directly to EU compliant raw material sourcing, where this documentation supports placing materials on the market.
Frequently asked questions
A certificate of analysis (CoA) is a document confirming that a specific batch of a raw material meets its agreed specification. It lists the tested parameters, such as identity, purity, assay, or particle size, and the results for that batch.
We confirm a certificate of analysis, the specification sheet, and where relevant batch or mill records, checking them against your spec before the order proceeds. For metals this includes a mill test report, and for chemicals a safety data sheet.
If a raw material drifts outside spec between batches, it can change how your product performs and force re-qualification. Confirming documentation per shipment keeps each lot inside the spec you approved, so your process stays stable.
