Hemp-derived CBD products — oils, capsules, gummies, and topicals — require comprehensive third-party testing to comply with state regulations, retailer COA requirements, and FDA enforcement priorities. Residual solvents from CO₂ and ethanol extraction, heavy metals from soil, pesticide residues, and mycotoxins from improper storage are the four critical safety parameters.
Hemp is a phytoremediator — it actively absorbs metals from soil. Combined with solvent extraction, potential pesticide use, and moisture-prone storage, CBD products face a unique multi-hazard testing challenge that generic supplement COAs do not address.
CO₂ extractions can carry trace hydrocarbons; ethanol and butane extractions require Class 1 and Class 2 solvent testing. ICH Q3C limits apply.
Hemp absorbs cadmium, lead, arsenic, and mercury from agricultural soil. California Prop 65 and FDA action levels require ICP-MS verification per lot.
Licensed hemp cultivation may still carry pesticide carryover from previous agricultural use of the same land. Multi-residue GC/MS and LC/MS/MS screening covers 200+ compounds.
Improperly dried or stored hemp is susceptible to aflatoxin and ochratoxin A contamination. Mycotoxin screening is required by EU import regulations and many US retailers.
Most state hemp programs require third-party COA for all finished product lots. We format COAs to satisfy state board, retailer, and distributor documentation requirements.
Water activity (Aw) analysis for gummy and soft-gel CBD products predicts microbial growth risk and shelf stability — often required alongside microbiological testing.
Standard hemp/CBD product testing:
