Are heavy metals and pesticide residues tested on every batch?

Yes — heavy metal screening and pesticide residue checks are part of the routine batch quality control, in addition to pH, specific gravity, microbial limits and sensory evaluation.

Contract farming and controlled picking practices reduce the residue baseline at the source, and the results are documented in the batch COA. For your destination market, we can arrange expanded third-party testing (e.g., EU/US pharmacopeia limits, specific MRL lists) against your specification.

Send your required limits or destination standard and we will confirm coverage on the next batch.
