Certificates of Analysis
COAs can be found in the COA tab on the product page. Match the lot number of your product to the lot number in the COA tab and click on View COA.
Please email firstname.lastname@example.org if you cannot find the COA for a particular product.
A Certificate of Analysis, or COA, is a document from an accredited laboratory that tells you exactly what is and isn’t in the product. These reports include product information such as the lot number, the manufacturing date, and active and inactive ingredients. You’ll also see an analysis of the bulk oil and its CBD content, terpenes, and physical attributes of the hemp oil.
If you didn’t get a COA from the supplier’s website, customer service, or the product label (QR code), that would be a “red flag.” A quality CBD company will always have its products lab tested. COAs are vital to double-check the quality and compliance of products and for consumer transparency.
Here are a few things to understand in COA reports
This is a look at the isomers of CBD and THC. Some labs report non-detectable or ND for THC content. Other labs use Limit of Quantitation or <LOQ, meaning the test product doesn’t contain enough of the ingredient for sensitive lab equipment to measure. Whether it’s indicated as ND or <LOQ, it means the product is THC-free.
Like THC measurement, you’ll see a reporting of ND or <LOQ if no pesticides are present. This pesticide testing covers 59 different pesticides.
This covers microbial contamination, particularly yeast, mold, salmonella, and E. coli. This testing looks at current contamination and the ability for those microbes to grow in the future. These tests abide by USP regulations for limits on microbial.
This includes arsenic, cadmium, lead, and mercury, which are all heavy metals that can be found in soil and be present on manufacturing equipment. This testing adheres to California’s rules, which are the strictest in the country.
What to look for in a COA
THC levels: To be considered hemp oil, by law, it cannot contain more than 0.3% THC. If the THC levels are higher, then the FDA considers it marijuana and may not be legal in your state.
Amount of CBD on the label: It’s essential to inspect the Certificate of Analysis for the CBD level and make sure it matches the level of CBD on the title of the purchased product.
Advertised cannabanoids: If a CBD product is marketed as Full Spectrum or Broad Spectrum, that means it contains a variety of cannabinoids. The COA should show the product has at least small amounts of other cannabinoids extracted from the hemp plant, in addition to CBD.
Third party tested: The certificate of analysis must come from a lab other than the product's manufacturer. This will ensure no biases in the testing process and the results.
