FAQ Header

Do you test for heavy metals and pesticide residues?

Yes. Every production lot is tested for heavy metals (lead, arsenic, mercury, cadmium) and pesticide residues before release, with limits aligned to international food-flavor and cosmetics safety requirements.

Testing Program

TestMethod / ReferencePurpose
Heavy metals (Pb, As, Hg, Cd)ICP / AASSafety compliance for cosmetics and food use
Pesticide residuesGC-MS/MS multi-residue screenCovers common agricultural residues on flower crops

MicrobiologicalTPC, yeast & moldHygiene for cosmetics and food applications
Results appear in the COA, and full third-party reports (SGS/BV/Intertek) can be arranged before shipment at your cost. Lavender is a field-grown crop, so residue screening is standard for our entire essential-oil line.

Request the latest heavy-metal and pesticide test results and we will send them with the current COA.
