Manufacturing & lot review
Manufacturing-document scope is reviewed against the supplied product’s label, lot and expiry. Manufacturing information is provided on a product-specific basis.
Product documentation
Request specifications, labeling / IFU, applicable finished-product CoA and registration documents. Document availability is confirmed for the product and destination market.
Market availability
Tell us your destination country and importing entity. Availability is confirmed after review of product-specific registration and import requirements.
Displayed specifications follow brand-provided information. Verify the current supply label and specifications when ordering.
Quality, reviewed through specific criteria.
We review raw-material and finished-product documentation according to the product’s characteristics and applicable specifications.
Composition & properties
Material identity, composition, concentration, pH and product-specific physical specifications
Finished-product testing
Applicable sterility or microbial, endotoxin and residual-substance test parameters
Lot traceability & packaging
Lot number, expiry, fill volume, package integrity and storage conditions
For HA products, we also review applicable residual BDDE specifications for cross-linked formulations, viscoelasticity and osmolality.
We publish certifications and test values only when valid supporting documents have been verified for the relevant product, model, manufacturing site or lot. We check the issuer, issue date and scope, and distinguish raw-material results from finished-product results.
These are product-specific review criteria, not a statement that every product has completed every test or holds a certification.
