Expert Chitosan Manufacturer Solutions You Can Trust
Turning what was once considered waste into a high-value product reflects both resourcefulness and responsibility. This is especially true for the production of chitosan, a biopolymer that has achieved international recognition for its versatility and sustainability. Global demand for high-quality chitosan has been steadily rising thanks to its role in medical devices, supplements, food, and agriculture.
Few companies can truly claim the combination of reliable scale, certified quality, and continual innovation. There’s a distinct advantage when expertise meets meticulous sourcing, production, and compliance, a characteristic found in manufacturers committed to exceeding both regulatory requirements and client expectations.
EU-certificate plant No. 502.09.A/B/C
PT. Fresh On Time Seafood, Indonesia
Our primary human consumption products are seafood, including crab meat products. Raw materials of our Chitosan products are from the by-products (crab shells) of seafood products.
With raw materials, we use snow crab (Opilio crab and Alaska/King crab) shells from our GMP food processing factory. Our raw material meets the requirements of Regulation (EU) no. 722/2012 (Medical Devices Risk Management and Controls to Prevent Spreading Certain Animal-borne Diseases to Users of Their Products). Our Chitosan products are under EU-manufacturer certification
Bridging Seafood Excellence with Innovative Biopolymer Manufacturing
The foundation of exceptional chitosan is rooted in the quality of the raw material. In this case, the raw materials—snow crab shells from Opilio and Alaska/King crab—are not just byproducts; they're a testament to a lineage of thoughtful, responsible seafood processing. Originating from a GMP food processing factory, these shells represent a sustainable source, directly tied to primary human food consumption, particularly premium crab meat products.
Operating under the umbrella of PT. Fresh On Time Seafood in Indonesia, a plant boasting the EU-certificate No. 502.09.A/B/C, the transition from seafood to biopolymer represents advanced risk management and stringent controls. Because the material meets Regulation (EU) no. 722/2012, it aligns perfectly with the highest medical device risk standards, minimizing animal-borne disease risk—a requirement especially critical for pharmaceutical and medical device manufacturers.
The harmony between resource utilization and safe, high-quality bioproducts sets a global benchmark. This commitment ensures that the chitosan is not just sustainable but also meticulously managed for traceability and purity.

Setting Standards for Traceability and Food Safety
Traceability is more than a buzzword; it's a necessity for manufacturers serving the food and pharmaceutical industries. BIO21’s chitosan supply chain is designed for full-backward tracking: from the seafood factory’s fresh crab inputs right up to each bag of processed biopolymer.
This practice supports not only regulatory compliance but also customer confidence. By maintaining an unbroken chain of custody, manufacturers can instantly validate the origin, processing, and quality status of every shipment.
Food safety is meticulously maintained through:
| • Systematic documentation at every production stage. |
Decades of Mastery: STABLE, SCALABLE, RELIABLE
Two decades of dedicated chitosan production translate to unparalleled consistency and scale. BIO21, since 2005, has stood at the forefront of industrial-scale manufacturing, consistently delivering more than 60 MT per year. This record of supply cements trust with customers whose operations depend on an uninterrupted, quality-assured chitosan inventory.
A monumental step in innovation came in 2023, with BIO21’s strategic partnership with PT Fresh On Time Seafood, an EU-certified, GMP/HACCP facility. This collaboration augmented both quality systems and production capacity, fueling the ability to deliver more than 100 MT per year—across the full spectrum of food, supplement, medical, agricultural, and industrial specifications.
