Raw blossoms come from controlled fields with reduced chemical input, and pre-harvest residue monitoring is part of our supplier management. In case your market has stricter thresholds (e.g. EU MRLs, California Prop 65), we test against those limits before shipment.

Provide your target market's limit list and we will issue a conformity statement with supporting lab data in your required format.
