Supplier qualification is a documented decision that a supplier can consistently meet defined requirements. It is not a collection of certificates or a single clean COA. The depth of review should match the ingredient, application, market and risk.
Build the requirement before sending a questionnaire
Define identity, composition, microbiological, elemental impurity, ingredient-specific, packaging, storage and shelf-life requirements. Identify which methods, units and limits are mandatory. A supplier cannot be meaningfully approved against an undefined target.
Review the specification and COA together
The specification states what is acceptable; the lot COA reports what was found. Confirm the same product name, units and methods appear across both. Ask how out-of-specification results are investigated and whether results come from in-house or external laboratories.
Map traceability
Request the lot coding structure and a high-level chain from cultivation or raw material through processing, packing and shipment. Ask whether the supplier can perform a mock trace and how quickly it can identify affected lots. Traceability must include rework and repacking where applicable.
Evaluate the quality system
For Canadian natural health product activities, Health Canada requires licensed sites and good manufacturing practices for activities such as manufacturing, packaging, labelling and importing. The current site-licensing information is a starting point; the buyer must still verify which site and activity a document covers.
- Document control and training
- Supplier and raw-material controls
- Sanitation and pest control
- Calibration and maintenance
- Deviation, complaint and recall systems
- Release authority and retained samples
Check change control
Ask what changes require notification: production site, organism or source, extraction, carrier, test method, specification, package or shelf life. Put notification timing and approval responsibilities into the quality agreement where appropriate.
Monitor after approval
Track incoming results, document completeness, delivery, deviations, complaints and changes. Set a requalification interval based on risk and performance. Approval is a maintained status, not a permanent badge.
Assign a risk tier
Risk can rise with vulnerable consumers, high use level, long supply chains, limited downstream processing, complex claims or a history of deviations. Higher-risk suppliers may need an on-site or remote audit, more frequent testing or tighter change control. Lower risk should be justified by evidence, not simply by a long commercial relationship.
Keep an approval trail
The supplier file should show who reviewed each document, which gaps were accepted, what conditions remain open and who authorized approval. Link the approval to the exact product and site. If a certificate expires or a site changes, the file should trigger reassessment instead of silently carrying the old approval forward.
Make the next supplier conversation more useful
AimGrow supplier qualification should be based on the documents currently available for the exact product and lot. Review AimGrow Spirulina Powder, then send the required-document list. A website statement should never replace the buyer’s own approval process.
