AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and limited company located in Xi'an, China, with four employees and a valid import/export license. It reports ODM and OEM capabilities, sample-based customization, new product launches during the past year, and export sales representing 71%–90% of total sales. However, its overseas service infrastructure is limited: it has no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Service-management documentation is also weak, with no written assessment or corrective-action procedures and no written complaint-handling records. Financial information is limited to references to 2020–2022 financial and cash-flow records without performance figures, so financial credibility cannot be fully assessed. No certification information, production-scale evidence, or customer case evidence is provided.

Product Q&A

Q:What is PDRN?

PDRN stands for polydeoxyribonucleotide, INCI name sodium DNA. It is a DNA fragment purified from the testes of deep-sea salmon. It has a 98% homology with human DNA and is extremely biocompatible.

Q:What is the source of the raw materials? Is there a risk of animal allergies?

The raw materials are extracted from Pacific salmon milt and undergo multiple purification processes to remove protein impurities. Only DNA nucleotide fragments are retained; no intact cells are present. The allergenicity is extremely low, and there is virtually no risk of allergic reactions. It is safe for use by those with sensitive skin and those who have undergone cosmetic procedures.

Q:Can you provide testing reports?

Yes, we can provide third-party HPLC purity testing, microbial, endotoxin, and protein residue testing reports. We also support export qualification documents.
