Are your products food grade?

Yes, we offer food-grade sodium bisulfite and sodium metabisulfite that comply with FDA and international food safety standards.

What packaging options do you offer?

We provide 25kg multi-wall paper bags with inner polyethylene liners, as well as bulk packaging options upon request.

Can you provide certificates of analysis?

Yes, we provide CoA, MSDS, and other documentation for every shipment to ensure traceability and compliance.
