How to Read a Certificate of Analysis (COA) Before Stocking Hemp Products

As hemp products become more popular in retail, wholesalers and store owners face an important responsibility: stocking safe, compliant, and high-quality items. One of the most reliable tools for ensuring this is the Certificate of Analysis (COA). A COA is more than just a lab report—it’s the key to protecting your business, building customer trust, and demonstrating compliance with both state and federal hemp laws.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis is a third-party laboratory report that verifies the cannabinoid content, safety, and compliance of a hemp-derived product. For wholesalers, this document proves that the product matches its label, is free from harmful contaminants, and is legal to sell under both state and federal guidelines.

The FDA’s consumer update on CBD stresses the importance of transparency in CBD and hemp markets. By requiring COAs, retailers can make sure the products they sell meet safety standards and consumer expectations.

Why Retailers Should Always Check COAs

Verifying COAs isn’t just good practice—it’s essential. Retailers who skip this step risk stocking non-compliant or unsafe products, which could lead to fines, liability issues, or damaged customer trust.

Beyond compliance, COAs act as a powerful marketing tool. Consumers increasingly want assurance that what’s on the label matches what’s in the product. A clearly published COA demonstrates transparency and builds loyalty.

The FDA’s warning letters show how costly ignoring compliance can be for businesses that mislabel or sell untested hemp products.

How to Read a COA Step by Step

Reading a COA may feel technical at first, but breaking it into steps makes it straightforward:

Step 1: Verify Product Information
Check the product name, batch or lot number, and testing date. These should match what’s on the product packaging.

Step 2: Cannabinoid Profile
Review the levels of CBD, THC, and other cannabinoids. For compliance in Virginia, THC must remain within legal limits, and labeling should reflect the actual content.

Step 3: Safety Tests
Look for testing results on heavy metals, pesticides, microbial contaminants, and residual solvents. These ensure the product is safe for consumers.

Step 4: Lab Credentials
Confirm the COA comes from an accredited third-party lab with ISO certification. Pure Shenandoah partners with trusted labs like Green Valley Analytics and ECC Testing Labs to guarantee accuracy and credibility.

Red Flags to Watch For

When reviewing a COA, be cautious if you notice:

  • Missing safety tests (pesticides, heavy metals, solvents).

  • Cannabinoid levels that don’t align with the label.

  • Outdated COAs

  • Reports from labs without accreditation or independent verification.

If you see these warning signs, think twice before stocking that product.
