A Certificate of Analysis (COA) is an official document issued by a third-party laboratory that provides detailed information about the composition, quality, and safety of a product. In the context of hemp-derived products, COAs are commonly used to verify the potency of cannabinoids (such as THC and CBD), the presence of contaminants (such as pesticides, heavy metals, and residual solvents), and other important parameters.

COAs typically include the following information:

  1. Product information: This section identifies the product being tested, including its name, batch or lot number, and any other relevant details.
  2. Test results: The COA provides quantitative data on the levels of cannabinoids present in the product, usually expressed in percentages or milligrams. This includes major cannabinoids like THC and CBD, as well as other cannabinoids like CBG, CBC, and CBN, depending on the product.
  3. Contaminant analysis: The COA also includes results for various contaminants that may be present in the product. This can include tests for pesticides, heavy metals (such as lead, arsenic, cadmium, and mercury), microbial contaminants (such as bacteria, yeast, and mold), residual solvents (if applicable), and mycotoxins.
  4. Safety and compliance: COAs often include information about whether the product meets safety and compliance standards set by regulatory authorities. This includes limits for THC concentration based on legal requirements.
  5. Date of analysis: The COA indicates the date when the product was tested and the analysis was performed. This helps ensure that the information provided is up-to-date and relevant.
  6. Laboratory information: The COA also includes details about the laboratory that conducted the analysis, including its name, address, accreditation status, and contact information.
