Import Chitosan — Buy in Bulk from Supplier in China

Chitosan is a natural biopolymer obtained by de‑acetylating chitin, a fibre found in crustacean shells. The product listed by Hangzhou New Asia International Co., Ltd. shows a purity level of over 90%, which is suitable for food and pharmaceutical uses. It is supplied in two physical forms - a fine powder and pre‑filled capsules - allowing manufacturers to choose the format that fits their processing line. Each batch is sealed in an airtight, moisture‑proof container and the supplier cites ISO and FDA certifications as evidence of compliance with international standards.

In the broader market, chitosan typically exhibits a degree of deacetylation between 80 % and 95 %, influencing its solubility profile. The molecular weight of commercial grades usually ranges from 50 kDa to 200 kDa, giving rise to viscosities of 100‑500 cP at a 1 % solution. Standard specifications also call for a moisture content of 8‑12 % and a colour ranging from white to off‑white, which affect handling and end‑product appearance. Buyers should compare these typical ranges with the batch data provided by the supplier to ensure alignment with formulation requirements.

Primary users of this chitosan include nutraceutical manufacturers, cosmetic formulators and food processors seeking a natural fat‑blocking or stabilising agent. The supplier mentions flexible minimum order quantities and offers both CIF and FOB shipping options from ports in China. Importers are advised to confirm the exact incoterm, lead time and payment terms directly with the supplier before finalising the contract. Requesting a current Certificate of Analysis and a copy of the ISO/FDA documentation will help verify that the product meets the stated purity and safety criteria.
