Every batch we quote has a current third-party certificate of analysis. This page explains what the certificate covers, how to read it, and what we check before controlled cannabinoids are released.

What the certificate of analysis covers

The certificate (COA) is issued by an independent laboratory, not by the producer. Which panels apply depends on the format of the material.

Panel What it shows Applies to
Cannabinoid potency Full cannabinoid profile by HPLC: the target cannabinoid in percent by weight, plus CBD, THC and the main minors. All materials
Residual solvents Ethanol, heptane, pentane and other process solvents, reported against USP <467> limits. Distillates, isolates, solvent-extracted concentrates
Heavy metals Lead, arsenic, cadmium, mercury by ICP-MS. All materials
Microbials Total aerobic count, yeast and mould, E. coli, Salmonella. Edibles, pre-rolls, water-soluble grades, concentrates
Pesticides Multi-residue screen on the plant input. Where reported by the producer for the batch

The COA you receive with a quotation is for the batch we would ship. If a batch changes between quotation and dispatch, you receive the new certificate before the goods leave.

Reading the potency line

Isolates are typically reported above 99 % of the target cannabinoid. Distillates are reported as a full profile: the target cannabinoid, the remaining minors, and any THC content. For CBD distillates sold as broad spectrum, THC is reported as not detected at the laboratory’s limit of quantification. For THC-analogue products, the certificate also reports the Δ9-THC content, which is what most EU customs and licensing rules turn on.

Compliance checks before release

Cannabinoids sit in very different regulatory boxes across the EU. CBD, CBG, CBN, CBC and CBT are generally not controlled. THCa converts to THC on heating and is treated as a THC product almost everywhere. HHC, THCp and the THC isomers and homologues are controlled substances in a growing list of member states and, for HHC, internationally since December 2025.

For those groups we quote only to buyers who can show the authorisation required in their country, and we keep that check on file with the order. The buyer remains responsible for the legality of the material at destination and for any import licence.

Regulatory status is stated on every product page and category. It is a summary, not legal advice; confirm the current position in your own country before ordering.

Storage and handling

Distillates ship in sealed glass or food-grade containers and should be kept cool and dark; warm gently before dispensing. Isolates are hygroscopic and should be resealed after use. Concentrates and terpenes ship cold and should be refrigerated on arrival. A short handling note is printed on each product page under “Handling and storage”.
