BIS FMCS stands for Foreign Manufacturers Certification Scheme, a program introduced by BIS to allow overseas manufacturers to use the ISI mark on their products. Under this scheme, foreign companies can obtain BIS Certification for Foreign Manufacturer and legally sell their products in India. The scheme ensures that products manufactured outside India comply with Indian Standards (IS) before entering the market. It is mandatory for several product categories such as electronics, cement, chemicals, and household appliances.
