How do you handle quality complaints or disputes?

We follow a 48-hour response protocol with retained samples: investigate against the batch COA/GC-MS, agree a remedy (replacement, credit or rework), and implement corrective action.

Complaint Handling Process

StepActionTimeframe
1Complaint logged with batch number + evidence (photos/COA)Day 0
2Investigation vs retained sample & GC-MS records48 hours
3Root cause & remedy proposal5 working days
4Remedy execution (replacement/credit/rework)10 working days
5Corrective & preventive action (CAPA) reported30 days
Every batch is backed by a retained sample stored for 36 months, so disputes are resolved against objective evidence rather than argument. If the fault is ours, we replace or credit at no cost; transport damage is covered via insurance claim with our logistics support.

A single named quality manager handles your account for consistency. Report any issue with the batch number and we will open a case within 4 working hours.
