🎓 Understanding Finished Product COAs: What Manufacturers Should Check Before Shipping

Introduction

Finished-product COAs are one of the most important documents in hemp manufacturing. They validate product integrity, demonstrate compliance, support retailer onboarding, and build consumer trust.

This article breaks down exactly what manufacturers should look for before approving a batch for sale.


📌 1. Potency Consistency With Label Claims

COA potency must match the label within acceptable tolerance.

Check:

  • mg per serving
  • mg per container
  • Total cannabinoids
  • Cannabinoid ratios

If the COA doesn’t match the labeled values, the batch cannot be released.


🧪 2. Total THC Calculation

Verify that total THC = Δ9-THC + (THCA × 0.877) is compliant.

Even if your SKUs are THC-free, this number must be clear.


🧫 3. Microbial Safety

Ensure the COA includes:

  • Yeast & mold
  • Total aerobic count
  • Pathogens (E. coli, salmonella)

These must pass current safety standards.


♨️ 4. Residual Solvent Screen

Check for:

  • Ethanol
  • Butane
  • Propane
  • Hexane
  • Heptane

Values should be ND (not detected) or well below action limits.


⚛️ 5. Heavy Metals

Your COA should show levels below detection or below federal guidelines for:

  • Lead
  • Arsenic
  • Cadmium
  • Mercury

📝 6. Packaging COAs (Optional but Valuable)

Packaging COAs confirm:

  • Child-resistant certification
  • Material compliance
  • Shelf-life compatibility

Retailers appreciate this additional layer of documentation.


🔗 7. Match COA, Label, BPR & Ingredient Inputs

Before releasing a product, verify alignment across:

  • Finished-product COA
  • Batch Production Record
  • Ingredient COAs
  • Labeling statements

This is where many brands gain or lose retailer trust.


🔚 Final Thoughts

Finished-product COAs aren’t just paperwork — they’re proof of consistency, safety, and professionalism. Brands who maintain strong COA alignment across every stage of production win more retailer trust and operate more efficiently.

Low Gravity Hemp provides clean, clear cannabinoid inputs that make COA alignment simple.
