Lab Testing & Certificate of Analysis (COA) Policy
Last Updated: July 2025
At Bulk Weed UK, we believe that every buyer — whether in the UK, EU, or Canada — deserves full transparency. That’s why all of our THCA flower, CBD concentrates, and bulk cannabinoid products are lab-tested by third-party accredited laboratories.
This policy outlines how our Certificate of Analysis (COA) system works, what you can expect on delivery, and how we maintain compliance with UK cannabinoid regulations.
🧪 Why Lab Testing Matters in Cannabis Wholesale
In the legal hemp and THCA space, especially under UK and EU law, lab testing is not optional — it’s essential. Here’s why:
- Confirms cannabinoid content and purity
- Detects any presence of THC, pesticides, or heavy metals
- Confirms the product meets UK Misuse of Drugs Act 1971 THC thresholds
- Validates novel food exemption for non-ingestible industrial products
- Protects B2B clients from enforcement or import/export risk
- Enhances search engine visibility through science-backed trust content
✅ What You’ll Receive with Every Order
Every product shipped from bulkweed.co.uk is batch-linked to a COA which includes:

⚠️ Legality + Mislabeling Disclaimer
Some resellers in the UK falsely advertise THCA flower as legal based solely on low THC readings. This is incorrect and dangerous.
Bulk Weed UK complies with actual UK law, which prohibits flower that can be converted into THC (via heat/decarboxylation), regardless of initial THC content.
We sell THCA flower as novelty products only, with appropriate legal warnings and COAs to support that claim.
