COA Requirements for Consumable Hemp Products

Certificate of Analysis: an ISO/IEC 17025 accredited third party lab must verify each of your final products. A Certificate of Analysis is needed for each final product.

The COA for a consumable hemp product includes a 5-panel test that reports on all cannabinoids, pesticides, solvent residues, heavy-metal contaminants, microbiological contaminants listed in Rule to Implement Provisions of Act 498.

 The COA for floral hemp material (flower) includes a 4-panel test that reports on all cannabinoids, pesticides, heavy-metal contaminants, and microbiological contaminants listed in Rule to Implement Provisions of Act 498.

The COA must include:

  • The batch identification number, date received, date of completion, and the method of analysis for each test conducted
  • A potency test of the final product indicating the serving size, total THC per serving, total number of servings, and total THC per package, identified as milligrams per gram
  • Cannabinoid profile:
    • A cannabinoid profile listing all major phytocannabinoid constituents by percentage of dry weight
    • No consumable hemp product may contain more than .3% delta-9 THC or one percent total THC on a dry-weight basis. Except for floral hemp material, no consumable hemp product may contain more than 8 milligrams of THC per serving.
  • Category I and II Pesticides
    • The amount of any detected pesticide residues in the product in parts per million must be stated
    • Refer to Emergency Rule to Implement Provisions of Act 498 pages 2982-2983 for Maximum Containment Levels for detected pesticide residues
  • Solvent residues (not necessary for floral hemp material)
    • The amount of any detected residual solvent in the product must be stated in parts per million
    • Refer to Emergency Rule to Implement Provisions of Act 498 page 2982 for detected residual solvent thresholds for non-floral hemp
  • Heavy-metal contaminants
    • The amount of any detected heavy metal trace in the product must be stated in parts per million
    • Refer to Emergency Rule to Implement Provisions of Act 498 page 2982 for the threshold of microbiological contaminants allowed in the product
  • Microbiological contaminants
    • The amount of any microbiological contaminants in the product must be stated in colony-forming units
    • Refer to Emergency Rule to Implement Provisions of Act 498 page 2982 for the threshold of microbiological contaminants allowed in the product
