In today’s competitive hemp marketplace, quality and compliance aren’t optional—they’re everything. As brands race to meet demand for cannabinoid-infused products, verifying the purity and integrity of your bulk ingredients is what separates reputable manufacturers from risky ones.
That’s where the Certificate of Analysis (COA) comes in. It’s your most important document when sourcing hemp distillates, isolates, or other raw materials. Let’s break down what to look for and how to identify truly reliable suppliers.
🔍 What Is a COA and Why Does It Matter?
A Certificate of Analysis (COA) is a third-party lab report verifying the contents and safety of a hemp-derived ingredient. It confirms that the product meets compliance, potency, and purity standards before use in manufacturing.
Every batch of distillate or isolate should come with a COA that details:
- Cannabinoid potency (mg/g or % concentration)
- THC content (<0.3% to meet federal compliance)
- Residual solvent testing (ensures clean extraction)
- Heavy metals (safety verification)
- Microbial contaminants (E. coli, yeast, mold, etc.)
- Terpene profile (optional but valuable for product differentiation)
Each ingredient in our Hemp-Derived Ingredients Collection is backed by a verified COA and full traceability from source to shipment.
🧪 How to Read a Hemp COA
Understanding how to interpret a COA is critical for any formulator or procurement lead.
1. Potency Section
Shows the concentration of each cannabinoid. Look for:
- CBD, CBG, CBN, CBC, and minor cannabinoids
- Total Δ9-THC content below 0.3% (for hemp compliance)
- A consistent cannabinoid profile that matches your formulation goals
2. Residual Solvents
Indicates whether harmful solvents like ethanol, butane, or hexane remain post-extraction.
- Should read “ND” (Not Detected) or below federal action limits.
3. Heavy Metals & Pesticides
Ensures the extract was sourced from clean, well-managed hemp biomass.
- Watch for lead, arsenic, cadmium, and mercury.
- Pesticide levels should be well below detection thresholds.
4. Microbial Testing
Verifies that no yeast, mold, or pathogenic bacteria are present—essential for consumable and topical products.
5. Batch & Lot Identification
A trustworthy COA always includes batch numbers and matching product codes that trace back to production and shipment records.
Low Gravity Hemp maintains batch-level traceability and provides COAs for every order—ensuring transparency and confidence at every step of your supply chain.
🧭 How to Verify Supplier Integrity
Even a perfect COA isn’t enough if your supplier isn’t operating transparently. When evaluating bulk hemp ingredient vendors, look for these key indicators:
✅ 1. Third-Party Testing
Always request independent lab results—not internal documents. The testing lab should be ISO-accredited.
✅ 2. Consistent Documentation
Each new lot or production run should come with an updated COA. If you’re sent a “recycled” document or one with mismatched batch numbers, that’s a red flag.
✅ 3. Compliance Transparency
Reputable suppliers readily provide information about their hemp source, extraction method, and testing process.
✅ 4. GMP and Handling Standards
Suppliers should follow Good Manufacturing Practices (GMP) to prevent contamination and ensure product consistency.
✅ 5. Clear Communication
Trustworthy partners offer responsive customer support, technical documentation, and flexible logistics for B2B buyers.
