How do you handle complaints and quality disputes?

A 48-hour response commitment and batch-traceable resolution process. Because every batch keeps retained samples for 3 years, disputes are resolved on evidence, not argument.

Complaint Process

StepAction
1. ReportSend order/batch number, photos and issue within 15 days of receipt
2. ReviewWe check the retained sample and batch records
3. AnalysisThird-party lab test if needed (shared cost or per agreement)
4. ResolutionReplacement, credit or refund per fault assessment
5. CorrectionRoot-cause action logged in our quality system
Transport-damage claims follow the same route with the B/L and photos. Legitimate supplier faults are settled by replacement or credit — our goal is your next order, not a one-time sale.

Log a complaint with your batch number and we will respond with a resolution plan within 48 hours.
