Third-Party Analysis

Free Amino Acid Content Measured By Eurofins

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.

How It Is Made

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.

Why Buy Direct

What Is Actually 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.

Packaging

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.

Water-soluble compound amino acid powders at 35%, 45% and 80% total amino acids, hydrolysed from duck feather protein, plus a hydrolysed cattle bone Protein Powder at ≥ 90% crude protein. They are B2B fertilizer and feed raw materials, not consumer products.

Are you a factory or a trading company?

A manufacturer. The plant in Suzhou, Jiangsu covers 20,000 m² with 80+ workers and 4,000 tons of monthly capacity, shipping to more than 20 countries.

How is the amino acid content verified?

Every production lot is analysed by Eurofins (Chengdu), a CNAS-accredited laboratory, under 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.

Can I get a sample before ordering?

Yes. Free samples of 200 to 500 g ship with a batch COA for formulation testing, by courier worldwide.

What are the lead time and shipping terms?

30-day lead time for regular orders, FOB Shanghai or Qingdao, with around 50 forty-foot high-cube containers of capacity per month. T/T, L/C, D/P and O/A terms are available to qualified partners.
