How do you handle inspection and quality control?

QC is applied at raw material intake, during distillation, and before every shipment — with third-party inspection welcome.

QC StageCheck Items
Raw materialFlower grade, freshness, pesticide residue screening
In-processDistillation parameters, temperature, yield
Finished batchAppearance, pH, SG, aroma, GC-MS fingerprint
MicrobiologyTPC, yeast & mold, pathogens per batch
Pre-shipmentPackaging, labeling, seals, lot traceability
We support third-party inspections (SGS, Bureau Veritas, Intertek) before shipment — you may specify the inspection standard and lab. Inspection reports and photos are provided on request.

Tell us if your contract requires a specific inspection company — we will arrange it with the order.
