Do you test for heavy metals and pesticide residues?

Yes — every batch is tested for heavy metals and arsenic against GB 1886.264-2016 limits, and supplementary pesticide/mycotoxin screening can be arranged on request.

Heavy-metal results are printed on the batch COA before release, so your inbound QC can rely on the document instead of re-testing every lot. For cosmetics or food-export programs that demand extended panels, we coordinate third-party testing (e.g., SGS-style reports) against your target market's limits — EU, FDA, or Gulf standards.

The raw flowers come from managed plantations with controlled picking windows, which keeps heavy-metal and residue levels naturally low. Tell us which contaminant panel your destination market requires and we will quote the third-party testing cost and lead time within 24 hours.
