What is a Certificate of Analysis (CoA)?

If you are a consumer or a retailer in the rapidly growing CBD market, it is essential to have a thorough understanding of the CBD you are buying or selling.

Probably the best way you an do this is by looking at the CoA for the product.

What is a COA for a CBD Product?

A Certificate of Analysis (CoA) is an official document provided by an accredited laboratory that details the composition of a particular product.

In the context of CBD products, a CoA contains information about the cannabinoid profile, terpenes, and the presence of any contaminants such as heavy metals, pesticides, or residual solvents.

The primary purpose of a CoA is to show whether the product meets industry standards and regulations.

It also serves as a guarantee to consumers that they are getting a safe and high-quality product.

Why is a COA Important?

A CoA is vital for several reasons:


CBD products should be free of harmful contaminants. A CoA confirms that the product has undergone rigorous testing and is safe for consumption.


A CoA provides complete transparency into the contents of the product, allowing consumers to make informed decisions based on accurate information.

Regulatory Compliance

Many countries and states have strict regulations governing the production and sale of CBD products. A CoA ensures that the product complies with these regulations and avoids any legal issues for both the manufacturer and the consumer.

Quality Assurance

A CoA guarantees that the product meets the highest quality standards. This is particularly important when it comes to the concentration of CBD and other cannabinoids, as well as the absence of THC (the psychoactive component found in cannabis) in products labeled as THC-free.

How to Find Out if a CBD Product Has a COA

To determine if the CBD product you’re interested in has a CoA, follow these steps:

Check the Product Label

Many reputable manufacturers include a QR code or a batch number on their product labels.

Scanning the QR code or entering the batch number on the manufacturer’s website should lead you to the relevant CoA.

Visit the Manufacturer’s Website

If you can’t find a QR code or batch number on the label, visit the manufacturer’s website.

Most responsible companies will have a dedicated section for CoAs where you can search by product type or batch number.

Contact the Manufacturer

If you still can’t find the CoA, reach out to the manufacturer directly.

Reputable companies should have no issue providing the CoA upon request.

If a company is hesitant or unable to provide a CoA, it may be a red flag, and you should consider looking for an alternative product.

Does having a COA means that the product is FDA approved?

No, having a CoA for a CBD product does not mean that it is FDA approved.

A Certificate of Analysis (CoA) indicates that the product has been tested by an accredited laboratory for its composition, safety, and quality.

The U.S. Food and Drug Administration (FDA) has not yet approved most CBD products, except for Epidiolex, a prescription medication used to treat certain rare forms of epilepsy.

The FDA is still in the process of evaluating the safety and efficacy of CBD gummies and other products and has not established clear guidelines or regulations for their approval.

It is essential for consumers to be aware that while a CoA can provide valuable information about a product’s safety and quality, it does not guarantee FDA approval.

Always exercise caution and do thorough research before purchasing and using any CBD product.

How do I read the COA?

Reading a CoA for a CBD product can be confusing if you’re unfamiliar with the terminology and information presented.

However, understanding a CoA is crucial in determining the quality, safety, and efficacy of a CBD product.

Here’s a step-by-step guide to help you read and interpret a CoA:

1.Verify the Laboratory

Check the name and accreditation of the laboratory that performed the testing.

The lab should be an independent, third-party facility with ISO/IEC 17025 accreditation, ensuring that it follows industry standards.

2.Check the Product Information

Verify that the product name, batch number, and manufacturing date on the CoA match the information on the product label.

3.Cannabinoid Profile

This section lists the various cannabinoids present in the product, such as CBD, THC, CBG, and others.

Ensure that the CBD concentration listed matches the advertised amount on the product label.

For products labeled as THC-free or with less than 0.3% THC, confirm that the THC level is within the legal limit.

4.Terpene Profile (optional)

Some CoAs may include a terpene profile, which details the aromatic compounds found in the product.

Terpenes can contribute to the overall effects and benefits of CBD products.

5.Contaminant Testing

This section is vital to ensure the safety of the product.

It typically includes tests for:

  • Heavy Metals
  • Pesticides
  • Residual Solvents
  • Microbial Contaminants

6.Pass/Fail Results

The CoA may include a pass/fail result based on the laboratory’s criteria and applicable regulations. Ensure that the product has passed all tests.

7.Date of Analysis

Verify that the testing date is relatively recent, usually within the past year, to ensure the information is up-to-date.

By understanding how to read and interpret a CoA, you can make informed decisions about the CBD products you purchase and use.

Always look for products from reputable manufacturers that provide CoAs from accredited laboratories, ensuring quality, safety, and transparency.

Simple but Significant

A Certificate of Analysis (CoA) is an essential tool for ensuring the safety, quality, and regulatory compliance of CBD products.

As a consumer or retailer, always make sure to verify the existence of a CoA BEFORE purchasing or selling a CBD product.

This is much easier than buying a bad product and trying to return it later.
