What is a COA (Certificate of Analysis)?
A COA is the third-party lab report that shows cannabinoid potency, terpene breakdown, and safety testing (heavy metals, mycotoxins, pesticides, residual solvents). Always match the batch number on the COA with the product page.
Quick COA Checklist (preview)
- Batch number on COA matches product page.
- THCA % listed and Delta‑9 < 0.3% (check local rules yourself).
- Terpene panel present (helps pick flavor).
- No elevated heavy metals or solvent residues in safety panels.
- Lab name and accreditation visible (third-party lab).
- Harvest & pack dates on product page — freshness matters for flavor.
How to compare two batches
- Confirm batch numbers & COA date.
- Compare THCA concentrations and terpene percentages.
- Check safety panels for fail flags (any ‘Detected’ in banned pesticide lists).
- Prefer more recent pack dates for aromatic terpene preservation.
