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:
Submitting takes less than 5 minutes. Most projects turn around in 5–10 business days from sample receipt.
Send a brief project description — sample type, quantity, and timeline. We confirm turnaround and quote within one business day.
We'll send a submission form and our San Diego shipping address. Most samples ship ambient or cold depending on stability requirements.
Results are delivered as a signed PDF COA within the agreed turnaround. Rush service (2–3 business days) is available for urgent timelines.
Send us your samples and receive an ISO 17025 accreditation pending Certificate of Analysis. Results in 5–10 business days.
