A Certificate of Authenticity or COA is as much for the customer as it is for the company to double-check the quality of their work for quality assurance purposes. With CBD oil, this is especially important as there’s an unfortunate problem of companies mislabeling products. Protect yourself from fake or low-quality products by doing your due diligence by always checking the Certificate of Authenticity (COA). If the company does not provide one, it might be best to steer clear.

What is a Certificate of Authenticity (COA)?

A Certificate of Authenticity, is a document from an accredited laboratory that shows the quantity of various cannabinoids in a product. Manufacturers of CBD products should send every batch of every product they make to a lab for testing, to protect their customers and prove that their products have the correct marked amount of CBD as they advertise. Since we are a smaller company that makes all of their products in small batches, we try to have all of our products tested every 3 months, when our batches run low and we produce new ones.

Always check the COA before using a CBD product

COAs aren’t always easy to get your hands on before buying a product, and you may need to reach out to the company to request it. Some companies offer QR codes on the label that you can scan and be taken to a webpage with the product’s COA. However, for us all of our COAs are posted on our website and can be accessed here.

If you can’t get a COA from the manufacturer’s website, customer service, or the product label, that’s not a good sign. This usually means that these companies are trying to mislabel or hide what is truly in their products. A quality CBD company will always get their products lab tested.

4 Red Flags to look for in a COA

Once you get a Certificate of Authenticity, inspect it thoroughly. Here are a few things to watch out for.

  1. Too much THC

To be considered hemp oil, by law, it cannot contain THC levels above 0.3%. If it contains more, then it’s considered marijuana and may not be legal in your state. Also, if your product is advertised as containing no THC, then reading the COA is a good way to verify that claim.

  1. Less CBD than advertised

This one is obvious, but for good measure, we’re mentioning it. It’s very important to make sure the COA reflects the actual advertised CBD content on your product’s label.

  1. Missing cannabinoids

If a CBD product is marketed as full spectrum, broad spectrum, or PCR, that means it contains a variety of cannabinoids. The COA should show the product contains at least small amounts of CBDa, CBG, CBC, CBN, and/or other cannabinoids, in addition to CBD.

  1. Tested in-house

When buying a car from a stranger, you don’t take their word for the condition they claim the car is in. You check it out or bring someone with you that knows what to look for. That thought process should be similar when it comes to testing CBD products. If the COA came from the company themselves, meaning they tested it in-house, they might be telling the truth —but it’s not as reassuring as an unbiased professional performing the test. Unless you really trust a company, it’s a good idea to make sure their COAs come from an accredited third-party lab. If they don’t, ask if they can provide one as they may have both available.

How to read a COA lab test

COAs are not always easy to read, and there are many different formats.

Typically, you’re going to see COAs that show the results in one of the following three ways:

Milligrams (mg) of CBD in the full product

Milligrams (mg) of CBD per gram (g)

Milligrams (mg) of CBD per milliliter (ml)

Note that we are using CBD as an example, but the same goes for all other cannabinoids in the COA.

That first type of result means you don’t need to do any work or calculations, as it already shows you the total amounts of each cannabinoid in the product. However, for the others, you will need to know one thing about the product in order to make your calculations.

Before explaining those two test result formats, we should refresh our memory on units of measurements. A milliliter (ml) is a measurement of volume. So even though most liquid CBD products will show the size in ounces (oz), you can easily convert that knowing, 1oz will always equal 30ml. However, grams (g) is a weight. Two 30ml tinctures will not weigh the same in grams, as the weight is affected by each ingredient in the product’s unique formulation.

MG per G

If the results show the amount of cannabinoids per gram, then you need to know the total weight of the product in grams. The weight does not include the packaging, just the product itself. Most products do not show their weight in grams on the label, so you may need to ask or check if the COA contains that information. For example, a product weighing 25 grams with an advertised 300mg of CBD should have 12mg of CBD per gram.

MG per ML

If the results show the amount of cannabinoids per milliliter, then it’s a little easier. However, this type of measurement only (easily) works for liquids. Simply take the total milliliters of the product and multiply it by the amount of CBD per milliliter. Liquid tinctures will always tell you their size, such as 1oz (30ml) or 2oz (60ml).

So, for example, a 1oz (30ml) tincture with an advertised 300mg CBD should contain 10mg of CBD per milliliter.

Other Types of Lab Tests

In addition to the standard cannabinoid profile, it’s also common to find full-panel lab tests. These show the cannabinoid profile and terpene analysis, as well as checking for any molds, pesticides, or heavy metals that could be harmful over certain levels.
