What “Verified Indian Manufacturer” means on this page

Every company listed above is confirmed as the shipper of record for the goods shown against it in Indian customs export data, covering Indian customs export records, 2023–25. That is a verification of export activity, not an OZIANT audit of the factory. IEC, GST registration and the full company profile are held by OZIANT and sent by e-mail when a buyer asks about a specific company. Companies that register and submit IEC and GST directly carry the separate OZIANT Verified Exporter badge. Listing last rebuilt 15-08-2026.
