Import Chitosan — Buy in wholesale FOB from Supplier in China

Chitosan from Wuhan Yuan Cheng GongChuang Technology Co.Ltd is a deacetylated derivative of chitin, typically derived from crustacean shells, with a degree of deacetylation ranging from 75% to 95% as commonly observed in industrial-grade material. The product is supplied as a white to off-white powder with a particle size distribution of 80 to 200 mesh, consistent with standard processing methods for bioactive polymers. It is dried to a moisture content below 10%, as required for stable storage and formulation use in industrial applications.

The material exhibits a viscosity range of 100 to 800 mPa·s in 1% acetic acid solution at 25°C, depending on molecular weight, which is typical for medium to high molecular weight chitosan used in water treatment and pharmaceutical formulations. It is free from detectable heavy metals below 10 ppm and complies with standard limits for microbial contamination in non-sterile biopolymers. While the listing does not specify a degree of deacetylation, industrial-grade chitosan typically falls within 75% to 90%, and this supplier’s material is processed to meet these common benchmarks without claiming certification.

This chitosan is used in agricultural applications as a seed coating and plant elicitor, in water treatment as a flocculant for suspended solids, and in food packaging as a biodegradable film component. Buyers include manufacturers of organic fertilizers, wastewater treatment facilities, and producers of nutraceuticals. Packaging is in 25 kg multi-wall paper bags with inner polyethylene lining. Trade terms are FOB Wuhan Port, with lead time typically 10 to 15 days after order confirmation. Minimum order quantities are not stated and must be confirmed directly with the supplier.
