Client: SwissVital AG (Switzerland) A premium Swiss dietary supplement and beauty raw material enterprise specializing in salon-grade hair care serums, high-end compound vitamin tablets and natural skincare active ingredients, distributed to high-end pharmacies and private health institutions across Switzerland, Germany and France. The firm strictly adheres to EP, USP, cGMP and REACH standards, representing a quality-centric mid-to-high-end client.
The client purchased high-purity D-biotin (Vitamin B7) from China for the first time as the core raw material for its premium hair care line and oral nutrition tablets. Lacking familiarity with China’s D-biotin brand landscape, product grades and quality tiers, the client initially contacted three leading manufacturers for quotations, yet faced fragmented, biased information: each factory only promoted its own products and avoided objective competitor comparisons. Manufacturer A highlighted its 99% high-purity grade, Manufacturer B emphasized pharmaceutical compliance credentials, and Manufacturer C focused on customized powder services—none provided neutral cross-brand benchmarking data, stalling the client’s procurement process. The client commissioned HiSiaddi to deliver neutral brand research, model screening and tailored end-to-end recommendation services.
HiSiaddi formed a raw material research team that conducted factory site visits, reviewed third-party test reports and industry reputation data, and aligned brand performance with client requirements to shortlist five domestic manufacturers capable of mid-to-high-end supply.
