Is the hydrosol tested for heavy metals and pesticide residues?

Yes — every batch is tested for lead, arsenic, mercury and cadmium, with pesticide residue screening available per destination requirements, and results reported on the COA.

Because the raw material is fresh flowers distilled within hours, contamination risk is inherently low — but we still verify each batch and keep the results traceable. Where your market demands independent evidence, third-party testing can be arranged with SGS or Intertek.

Ask for the latest batch COA to review the actual heavy-metal and microbial values.
