Buyer Decision Guide
Specify Oyster peptide by the declared basis, the delivered form and the certificate of analysis. For this grade the basis is Protein >=90%; average molecular weight below 1,000 Da and the delivered form is Fine off-white powder. Confirm the destination market requirements, the intended use category and the required documentation before approval. This material is offered as an industrial raw material for further processing, not as a finished consumer product, and no health or medical claim is made.

How This Grade Differs
Oyster peptide is listed as Crassostrea gigas with protein >=90% and average molecular weight below 1,000 Da. Linked abalone and sea-cucumber peptides come from different species, while oyster whole powder is a different fraction. Compare species, assay basis and current batch documents before substitution.

How is identity confirmed on the COA?
Identity is confirmed against Crassostrea gigas (Pacific oyster), with the plant part recorded as declared on the specification.
Which safety parameters are tested every lot?
Moisture <=5.0%; result 4.20%, ash <=5.0%; result 3.80%, heavy metals and microbiology against the approved specification.
How is appearance checked?
Fine off-white powder, compared against a retained sample from the approved batch.
Which specification figure should the purchase order reference for Oyster Peptide Powder?
The figure Protein >=90%; average molecular weight below 1,000 Da, measured by Kjeldahl and SEC-HPLC.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
How is the material shipped?
