QUALITY PROCESS
How quality is maintained.
Supplier qualification
Raw material suppliers are qualified against a defined approval procedure. Incoming raw materials are tested against specification on every delivery. Non-conforming materials are quarantined and rejected.
In-process control
Documented manufacturing instructions govern each production batch. In-process checkpoints verify intermediate product at defined stages. Deviations trigger investigation before the batch proceeds.
Final batch release
Every batch is tested against the full specification listed in the TDS — viscosity, refractive index, specific gravity, appearance, active content, and applicable identity tests. The batch is not released until all values are within specification.
Certificate of Analysis
A Certificate of Analysis is generated for each released batch, listing the measured values for all tested parameters. CoA is available on request for every shipment and is retained in the batch record for 24 months.
Retain samples
Retain samples from every batch are held for 24 months from date of manufacture. Available for testing or investigation if required by the customer.
Internal audit
Internal quality audits are conducted to the ISO 9001:2015 schedule. Management reviews confirm system effectiveness. Continuous improvement actions are tracked to closure.
