How are quality complaints or discrepancies handled for tangerine oil?

Complaints are handled against the lot data, not against opinion.

Process

  1. Notify G4S in the validity window with the lot number, COA reference and the issue.
  2. The retained sample and the batch COA are reviewed.
  3. If a real non-conformance is confirmed, G4S offers replacement, credit or refund per the contract.
  4. For contested results a third-party lab (SGS, Eurofins) can be engaged, costs allocated by outcome.

Keep the original pack sealed where possible so the material can be verified.
