FAQs
Do you supply dye intermediates such as H-acid and vinyl sulfone?
Yes, these are sourced from producers in Gujarat's dye clusters. Specifications and purity are confirmed on the quotation and batch COA.
How is sodium hydrosulfite shipped?
It is a self-heating solid (UN 1384) and ships under IMDG rules in moisture-proof packaging, stowed away from heat and incompatible cargo.
Can you help with restricted-substance list (RSL) compliance?
We supply a COA and GHS SDS with every batch and can request additional composition statements from the manufacturer. Final RSL compliance depends on your process and brand requirements.
What order sizes are typical for textile chemicals?
Commodity auxiliaries usually move in full container loads, while intermediates and specialty items can be shipped in smaller drum or bag quantities.
