Questions & answers

Yes. We export worldwide by sea and air, on FOB, CFR or CIF terms, and also deliver within India by road.

Yes. Request a sample on any product page; we send it with a datasheet so you can test it.

It depends on the product, usually from 500 kg to one 20-ft container. Each product page shows its minimum order.
