I'm reaching out to inquire about chitosan, a versatile biopolymer widely used across various industries. I'm interested in understanding the different forms and specifications of chitosan you offer. Specifically, I'd like to know about the particle sizes, viscosity levels, and any modifications available. Additionally, please share your quality standards and certifications related to the production process. Furthermore, it would be great if you could provide information on your pricing structure, minimum order quantities, and lead times for delivery. I'm also curious about the packaging options you have available for shipping. Any samples you can provide would be highly appreciated to assess the quality. Looking forward to your prompt response so we can explore potential collaboration opportunities!
