Start with the product and the route
Define the material before building a shortlist: cannabis flower, a particular extract, an active pharmaceutical ingredient or a finished medicine. Record the intended application, target specification, required quantity, packaging and delivery location. Two materials sold under a similar general name may have different compositions, documentation and permitted uses.
Draw a simple route from the producer through any processor, importer, distributor and receiving organisation. Identify who takes possession, who invoices, where the material is stored and who makes the relevant quality decisions. A clear route makes gaps easier to spot before an order is placed.
Verify the exact partner and activity
Ask for the legal entity name, operating address and the permissions relevant to the proposed role. Check that the company named in an authorisation is the company you intend to contract with, and that the site and activity match the arrangement. BfArM’s trader application guidance illustrates the site, responsible-person and product information involved in medical cannabis permissions.
Treat a certificate sent by email as evidence to review, rather than a substitute for verification. Resolve discrepancies in entity names, addresses, product descriptions or document dates with the issuing body or the partner before proceeding.
Read quality evidence in context
Compare the current product specification with a representative batch Certificate of Analysis. Ask how batch identity, methods, limits and results relate to the exact grade under consideration. Review manufacturing evidence separately. The EMA’s GMP guidance describes the EudraGMDP database and the authorisations, certificates and non-compliance information it contains.
A batch test report and manufacturing-site evidence answer different questions. Avoid transferring an approval for one site, operation or material to another without checking its scope. Ask how the supplier handles a result outside specification, a material change or a complaint.
Agree how the material will move
Discuss storage conditions, transport responsibilities, packaging, handover records and the process for a delayed or damaged shipment. Set out who reviews any temperature excursion or other deviation and how a delivery is held while an issue is assessed.
Use a written responsibility matrix for outsourced activities. The European Commission’s EudraLex Volume 4 includes guidance on pharmaceutical quality systems, documentation and outsourced activities; the applicable requirements depend on the product and activity.
Test communication before committing
Request a small, complete documentation package and agree a realistic response date. A useful response identifies what is available, what remains outstanding and who will resolve it. Unexplained document mismatches, pressure to bypass qualification or unclear ownership of stock are reasons to pause and ask further questions.
Compare partners against the same brief. Record the outcome of document checks, the open actions and the decision-maker responsible for accepting any residual uncertainty. This is more useful than choosing on a single headline claim.
Build a relationship that can be reviewed
Qualification is a starting point. Agree how updated documents, changes in manufacturing arrangements, complaints and delivery performance will be communicated. Schedule a review that fits the importance and complexity of the supply relationship.
Dronivia can discuss your sourcing brief and the product or documentation questions you need to raise. The organisations carrying out each regulated activity remain responsible for their own authorisations, quality decisions and obligations.
