A Chain of Custody (CoC) is an unbroken, chronological record documenting the intake, custody, transfer, processing, and distribution of a material. In the hemp industry, a CoC tracks a cannabinoid extract backward through every processor and batch test to a legal, compliant harvest.
It is required because once a plant is extracted and refined, the final material cannot inherently prove whether it originated from compliant hemp (0.3% Delta-9 THC or less at harvest) or a controlled substance. The documentation serves as the sole legal proof of origin and compliance.
Why Hemp Requires a Chain of Custody
Under federal law, Cannabis sativa L. with a Delta-9 THC concentration of 0.3% or lower on a dry-weight basis at harvest is legal hemp. Any concentration above this threshold is a controlled substance.
Once biomass is extracted, refined, and processed into a cannabinoid concentrate, distillate, or isolate, nothing in the final material inherently confirms which side of the legal line it started on. A complete CoC connects the final extract directly back to the original, compliant harvest biomass, providing the necessary proof of legal status.
Core Components of a Hemp Chain of Custody Packet
A standard, fully compliant hemp CoC packet contains four essential documents for every stage of production:
- Batch-Specific Certificate of Analysis (COA): Verifies the potency, purity, and safety profile of the final material.
- Lab Accreditation Certificate: Demonstrates that the testing facility is ISO/IEC 17025 accredited.
- State Processor License: Confirms the manufacturing facility is state-authorized to handle hemp.
- Nested Extract Traceability: Documents each intermediate step from biomass to raw material.
Typical CoC Processing Stages
| Extract Type | Required Intermediate COA Milestones |
|---|---|
| Distillate | Harvest Biomass → Crude Extract → Mother Liquor (Optional) → Refined Distillate |
| Isolate | Harvest Biomass → Crude Extract → Purified Isolate |
PD's Emulsion Certificate of Analysis (COA)
Perfectly Dosed tests all of its finished emulsion products with an accredited third-party lab. These full panel test results (potency, heavy metals, residual solvents, pesticides, microbials, and mycotoxins) can all be accessed via the QR code on your product's back label.
What to Look for in a Chain of Custody
A complete Chain of Custody traces back to biomass, includes a license for every intermediate processor, and comes from a lab accredited for the specific tests it ran. Be sure to read carefully and inquire with your supplier about anything that looks off.
How to Request a Chain of Custody
Every Perfectly Dosed order automatically includes a full physical compliance packet containing:
- Compiled Chain of Custody
- Batch COA
- Product Specifications Sheet
- Finished Product Quality Report
