Thiamine is primarily used as a key ingredient in dietary supplements, daily multivitamins, fortified food products, and pharmaceutical formulations to support energy metabolism and nerve health.
We offer 1kg packages (double plastic bag + aluminum foil bag inside, boxed outside) for smaller quantities, and 10kg or 25kg drums or cartons (with 2 layers of inner plastic lining) for bulk shipments.
Yes, we offer free samples of our Thiamine powder, complete with supporting documentation including COA (Certificate of Analysis), TDS (Technical Data Sheet), and MSDS (Material Safety Data Sheet).
Thiamine should be stored in tight, light-resistant containers in a cool, dry place to prevent degradation and maintain product potency over its shelf life.
For small quantities up to 100kg, we use express air couriers (DHL, Fedex, EMS) or air freight, which takes 3-7 days. For quantities over 100kg, sea freight is also available, taking between 10 to 35 days depending on the destination port.
