What Buyers Need to See
Procurement teams and formulation chemists require specific documentation before placing an order. Here's what we provide -- without you having to ask twice.
Every batch ships with a full CoA. Technical Data Sheets include viscosity, purity, functional group content, and application guidance -- available for each product before you commit.
Request CoA / TDS →GHS-compliant SDS in English available for all products. Multi-language versions on request if necessary. Required for import clearance, workplace safety compliance, and downstream regulatory filings.
Request SDS →REACH registration numbers (or pre-registration status) and TSCA compliance statements provided for all core materials. Required for EU and US import and end-product compliance declarations.
Request Compliance Docs →From 1 gram to 5 kg, lab-scale samples dispatched within days of request. Formulation chemists can benchmark directly against current reference materials before any purchase commitment.
Request Lab Sample →All three production sites operate under ISO 9001 certified quality management systems. Supplier audit reports and factory qualification packages available upon request for procurement qualification.
Request Supplier Package →Two synthesis labs and two analytical labs (GC-MS, FTIR, NMR, viscometers). End-to-end development from gram-scale concept through ton-scale commercial production. Conflict-free -- we don't compete in downstream formulations.
