Introduction
Certificates of Analysis (COAs) are essential for retail acceptance, compliance, and consumer trust.
Before submitting your products to retail buyers, you must audit every COA for accuracy and compliance.
🧾 Step 1 — Verify Identity
Check:
- Product name
- Lot number
- Batch number
- Extraction type
- Spectrum classification
🧪 Step 2 — Potency Panel Analysis
Confirm:
- Total cannabinoids
- CBD/CBG concentration accuracy
- Δ9-THC <0.3%
- Total THC = Δ9 + (THCA × 0.877)
Retailers increasingly require total THC compliance, not Δ9-only.
🔬 Step 3 — Contaminant Panels
Retail-ready COAs must include:
- Residual solvents
- Heavy metals
- Microbial safety
- Pesticides
📄 Step 4 — Date & Accreditation
Check:
- COA date ≤ 12 months old
- ISO/IEC 17025 accreditation
- Signature or digital verification from lab
🧩 Step 5 — Label Match
Your COA must match:
- QR code
- Packaging potency
- Serving size conversion
- Total cannabinoids
Summary
Retailers expect fully verifiable COAs that demonstrate compliance, transparency, and accuracy.
