Suzhou Everwell Biotechnology Co., Ltd.
We hydrolyse duck feather keratin into fully water-soluble amino acid powder, so fertilizer formulators, importers and distributors can buy organic nitrogen and free amino acids by the container with a batch COA against every shipment.
Suzhou Everwell Biotechnology Co., Ltd. supplies compound amino acid powders to B2B fertilizer formulators, importers and distributors worldwide. Production runs from a 20,000 m² facility in Suzhou, Jiangsu with 80+ workers and 4,000 tons of monthly capacity, shipping roughly 50 forty-foot high-cube containers a month.
The powders are produced from duck feathers through controlled hydrolysis, purification, concentration and spray drying. That four-stage route delivers consistent quality across the 35%, 45% and 80% amino acid grades, plus a cattle-bone Protein Powder at ≥ 90% crude protein for feed and agricultural use.
Every production lot is analysed by Eurofins (Chengdu), a CNAS-accredited laboratory, under national standard GB/T 18246-2019. The April 2026 reports record 41.93% free amino acids for Amino Acids 45, 48.22% for Amino Acids 50 and 75.37% for Amino Acids 80. Each shipment is verified against the agreed specification and supplied with a batch-specific COA.
We support OEM and private-label packaging, from a 1 kg retail stand-up pouch to 20 kg multi-wall kraft bags, with multi-language labels on request. Regular orders ship on a 30-day lead time FOB Shanghai or Qingdao, with T/T, L/C, D/P and O/A terms available to qualified partners.

What Is Behind The Quotation
Factory, not a trading desk
The powder is hydrolysed, spray-dried and bagged in our own Suzhou plant, so the specification you agree is the specification the line runs to.
Third-party verified
Eurofins (Chengdu), CNAS-accredited, tests each production lot to GB/T 18246-2019. The free amino acid figures on this site are quoted from those reports.
Documentation with every batch
Batch-specific COA on every shipment; TDS and SDS available before you order. Free 200–500 g samples with their own COA for formulation testing.
Container-scale logistics
4,000 tons a month and around 50×40'HQ containers, FOB Shanghai or Qingdao, on a 30-day lead time for regular orders.
