🔍 What Is a Hemp COA?
A COA (Certificate of Analysis) is a lab report issued by an independent, certified testing facility. It breaks down what’s in the product, including cannabinoid potency, Delta 9 THC levels, and potential contaminants like pesticides or heavy metals. For THCA flower and other hemp-derived cannabinoids, a COA is essential to show that the product is:
-
Farm Bill compliant (less than 0.3% Delta 9 THC by dry weight)
-
Accurately labeled in terms of potency
-
Free from contaminants that could harm consumers
🧠 Why It’s Important to Know How to Read a Hemp COA
Too many smoke shop owners assume a product is compliant just because it looks good or sells well. But if you get caught selling non-compliant flower, it’s your business on the line, not the supplier’s. Understanding a COA helps you:
-
Protect your shop from regulatory issues
-
Avoid fake or inflated lab results
-
Gain customer trust by showing transparency
-
Ensure you're buying real THCA flower, not D8-sprayed mids
📊 How to Read a Hemp COA (Section by Section)
Here’s what to look for when reviewing a COA, especially for THCA flower.
1. Cannabinoid Potency Table
This section shows how much of each cannabinoid is present, often in % by weight or mg/g. Key ones to look for include:
-
THCA – You want 20%–35%+ for premium flower
-
Delta 9 THC – Must be under 0.3% to be compliant
-
CBD, CBG, CBN – Optional, but can affect the entourage effect
Example: If your THCA is 28.3% and Delta 9 THC is 0.19%, it’s compliant.
2. Total THC Calculation
Some labs calculate Total THC using this formula:
Total THC = Delta 9 + (THCA × 0.877)
If this value is under 0.3%, the product meets the legal definition of hemp. But watch out: Some states interpret the rules differently. Even if federally legal, you must check your state’s stance on Total THC vs. Delta 9 only.
3. Testing Date & Batch Number
Always confirm that the testing date is recent (ideally within the last 3–6 months), the batch ID matches the product packaging, and the lab is DEA-registered or ISO-accredited. If this info is missing or outdated, don’t trust it.
4. Contaminant Testing (Bonus)
Good suppliers will go the extra mile and provide full-panel testing for:
-
Pesticides
-
Residual solvents
-
Heavy metals
-
Microbial contaminants
Look for a status like “Pass” or “ND” (Not Detected) in these columns.
