01
Specification sheets, per customer
Limits are agreed before the first order and become the release criteria for every batch that follows.
Quality Assurance
Tested before dispatch, documented on arrival
Quality assurance at NPE is a release gate, not a certificate. Material moves only when measured values sit inside the specification agreed with your team.
Laboratory
In-house testing across every product family
Testing covers chemistry, particle size and density, with third-party verification available on request.
- Incoming feedstock qualification before processing
- In-process checks at drying, milling and classification
- Batch release testing against the agreed specification
- Retained samples held for post-dispatch traceability
Test schedule
Checks and reported outputs
The checks applied to a grade are fixed with the customer, so each consignment is assessed the same way. Measured values are issued on request.
| Check | Stage | Reported output |
|---|---|---|
| Feedstock identification | Intake | Lot recorded and released for processing |
| Moisture | In process | Recorded before milling and packing |
| Particle size / grain band | In process | Measured distribution for the grade |
| Chemistry | Release | Values reported on the certificate of analysis |
| Density | Release | Measured value for the consignment |
| Appearance and packing check | Release | Verified against the packing specification |
