Product Overview
Cotton-linter grades built for high-purity downstream uses
C Series covers high-purity grades made from cotton linters, with tightly controlled ash and iron content for sensitive esterification and other purity-critical routes. The linters go through alkaline cooking, multi-stage washing and bleaching, and an extended purification step to a bright, uniform pulp. Purity is tracked in-process every shift, and every batch ships with its own certificate of analysis.
- ✓Controlled ash & iron — tight impurity profile for sensitive esterification
- ✓Batch-to-batch consistency — process parameters logged every shift
- ✓COA per batch — α-cellulose, viscosity, ash, iron, whiteness and moisture reported
- ✓Custom grade matching — send your target viscosity or current TDS and our lab matches it

C Series — frequently asked questions
Quick answers on grades, documents and sampling. The full FAQ library lives in Resources.
Can you match a target viscosity or an existing grade?
Yes. Send us the viscosity window you need, or a TDS from your current supplier, and our lab will identify the closest C series grade. The match is confirmed with a pre-shipment sample and its batch COA before you commit to a volume order.
Is a TDS available before we place an order?
Yes. The C series TDS is issued on request with your inquiry, and the SDS is publicly available per regulatory requirements. A sample COA is also available so you can see exactly which parameters are reported batch by batch before you order.
How do samples and trials work?
After we agree on a candidate grade, sample bales are shipped with the matching batch COA so your trial results stay fully traceable. Tell us your application, estimated quantity and destination port, and our export team will handle sample logistics and documentation.
