Welcome!
What is a COA?COA stands for Certificate of Analysis. Harmony CBD vaping oils test every single batch of CBD with independent, third-party laboratories to ensure outstanding quality. They also periodically test finished products for their cannabinoid content. The certificates below apply to the vaping CBD oils we offer on our website which are manufactured by Harmony CBD.
It is easy to get a little bit confused when looking at our analysis results and seeing numbers that seem to be lower or higher than what they should be according to our packaging. But don’t worry, there is an explanation and, of course, we make sure you get the right amount of CBD in each of our products!
For your convenience, our packaging always tells you how much CBD is in the whole product container and how much is in 1 mL of product, so you don’t have to use a scale to find your perfect dose.
However, 1 mL of liquid can have a weight different from 1 g, depending on the type of product. At the same time, analysis labs report their results in weight or percentages.
To save you from the headache of doing lengthy calculations, we created some handy conversion tables for all our CBD products for you.

| CBD mg / mL | CBD mg / g | CBD % |
