The supplier operates three production lines, reports 6–10 R&D engineers and 6–10 quality-control staff, and provides testing capabilities covering chemical, physical, heavy-metal, pesticide-residue, and microbiological parameters. Export activity is substantial, with 90% of sales reportedly from exports, exporting experience since 2012, and markets spanning multiple global regions. Evidence supports raw-material supply, premix blending, and OEM services, but no customer names, project references, or independently verified performance data are provided. Financial credibility cannot be assessed because financial information is excluded.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and operates as a limited company in Changsha, Hunan, China. This supports classification as a direct manufacturing supplier rather than only a trader or service intermediary.

CertificationsThe supplier reports ISO 9001, ISO 22000, GMP, and HACCP certifications, while its chemical production line also cites ISO 22000, ISO 9001, Kosher, and Halal certifications.

After-Sales capabilityThe supplier states that it provides considerate, timely, and professional service and will accept responsibility and provide a full refund if product quality does not comply with customer specifications. This is explicit evidence of a stated quality-related remedy, but no service response metrics or documented case history are provided.

R&D capabilityThe supplier reports 6–10 R&D engineers, multiple extraction technologies including multifunctional and continuous countercurrent extraction, and broad testing capabilities covering assay, purity, residues, heavy metals, and microbiological indicators. These facts support technical development and process capability, but no patents, new-product records, or quantified R&D outcomes are provided.

Production capacityThe supplier operates three production lines for yeast products, chemicals, and plant extracts, with stated annual outputs including 80 tons of glutathione, 480 tons of active feed yeast, 120 tons of L-theanine, 65 tons of indole-3-carbinol, and 180 tons of yeast beta glucan.
