Hunan Sentai Biotechnology ships sodium carboxymethyl cellulose (CMC), polyanionic cellulose (PAC) and sodium carboxymethyl starch (CMS) from its plant in Xiangtan, China, to buyers in Latin America, including customers in Chile, Peru and Argentina. Orders start at 1 t for industrial grades, are quoted FOB Guangzhou or CFR and CIF to your port, and ship with a certificate of analysis for every lot. This page brings together what Latin American buyers usually ask: which grades suit the region's industries, how shipping and documents work, and how to order samples.
Grades for Latin American industries
| Industry | What CMC does | Sentai product family |
|---|---|---|
| Mining (copper, iron ore) | Depresses silicate gangue in flotation and binds iron-ore pellets | Mining-grade CMC |
| Detergents and cleaning products | Anti-redeposition in laundry powders; thickening in liquid detergents | Detergent-grade CMC |
| Food and beverages | Stabilises acidified milk drinks, ice cream, sauces and bakery fillings | Food-grade CMC (GB 1886.232-2016) |
| Oil and gas drilling | Fluid-loss control and viscosity in water-based muds | PAC-LV / PAC-HV and drilling CMC |
| Pulp and paper | Wet-end retention, surface sizing and coating colours | Paper-grade CMC and CMS |
| Ceramic tiles | Binds the green body and keeps glazes in suspension | Ceramic-grade CMC |
Chile and Peru are among the world's leading copper producers, Argentina, Mexico and Brazil drill for oil and gas, and Brazil and Mexico are large producers of ceramic tiles. Sentai's grades are specified for each of these uses, and its engineers can recommend a grade from your current specification.

Documents, duties and certificates of origin
Each shipment travels with the commercial invoice, packing list, bill of lading and a certificate of analysis for every lot, plus the TDS and SDS of the grade. CMC and PAC are classified under HS 3912.31 and CMS under HS 3505.10.
China has free-trade agreements with several Latin American countries, including Chile, Peru and Costa Rica, under which a certificate of origin can lower the import duty. Sentai's standard certificates of origin are CO, Form A and Form E; tell us which form your customs broker needs when you order.
Inspection before loading by SGS, BV or another third party appointed by the buyer is welcome.
Payment and ordering
- Minimum order: 1 t for industrial grades; battery grade negotiable.
- Payment: T/T with 30 % deposit and 70 % against a copy of the bill of lading; L/C at sight and D/P for established customers.
