Compound Amino Acid Powder, Hydrolysed And Spray Dried In Suzhou
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.
- 35%, 45% and 80% total amino acid grades
- 75.37% free amino acids verified by Eurofins on the 80 grade
- 4,000 tons a month from a 20,000 m² plant
- Batch COA with every shipment, 30-day lead time
Three Ranges: Amino Acid Powders, Protein Powder, Complementary Inputs
The amino acid powders and the protein powder are made in our own plant. The complementary inputs are partner-supplied and consolidated into the same container, which is stated openly on every one of their pages.

Every production lot is analysed by Eurofins (Chengdu), a CNAS-accredited laboratory, under national standard GB/T 18246-2019. Free amino acids are the fraction that is immediately plant-available, which is the number a formulator can put behind a label claim.

| Amino Acids 45 | 41.93% | AR-26-Y3-008790-02 | GB/T 18246-2019 | 29-Apr-2026 |
| Amino Acids 50 | 48.22% | AR-26-Y3-008792-02 | GB/T 18246-2019 | 29-Apr-2026 |

One Raw Material, Four Stages, Three Concentrations
01 Controlled Hydrolysis
Duck feathers undergo precisely controlled hydrolysis, breaking keratin protein down into individual amino acid chains.
02 Purification
Purification removes impurities so the amino acid profile stays consistent from lot to lot.
03 Concentration
The purified solution is concentrated to the target amino acid density for each grade specification.
04 Spray Drying
Instant spray drying preserves the amino acid fraction and produces a free-flowing, fully water-soluble powder.

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.
From A 1 kg Retail Pouch To A 20 kg Distribution Bag
A white stand-up zip pouch with green side panels for vegetable-market distributors and fruiting-crop retailers, and a heavy-duty kraft bag with a PE inner moisture barrier for wholesale and farm supply. OEM and ODM artwork, multi-language labels and 25 kg woven bags or custom sizes are available on request.
