01

Start with source species and origin

Animal-derived ingredient RFQs should state bovine, porcine, chicken, fish or marine source preferences, plus any origin-country restrictions.

02

Match assay method before comparing price

Collagen peptide and chondroitin sulfate prices cannot be compared unless assay method, protein or active content, molecular-weight range and document scope are aligned.

03

Confirm allergen and BSE/TSE documents early

Allergen statement, source statement, BSE/TSE support, halal or kosher availability and contaminant limits should be checked before sample or bulk quotation.
