Do you provide a Certificate of Analysis (COA) for every batch?

Yes — a COA is issued for every batch, covering sensory, physico-chemical, microbiological and safety parameters, plus batch traceability.

COA SectionTypical Parameters
IdentityBotanical name, INCI, product code, batch no.
SensoryAppearance, color, aroma
Physico-chemicalpH, specific gravity, refractive index
MicrobiologicalTPC, yeast & mold, pathogens
SafetyHeavy metals summary, allergen notes
TraceabilityHarvest date, origin, production date
COAs are provided in a bilingual format (English/Chinese) by default, and we can adapt the template to your spec sheet or retailer requirements. If your formula has tight acceptance windows, we align the COA limits to your specification before production.

Share your COA template and we will fill it per batch with your reference number.
