SSI and MSME are the same. Earlier industries that were into manufacturing products, providing services, and producing goods on a small scale were allowed to carry out the Small-scale industries (SSI) registration.  The government and respective authorities passed the MSME (Micro, Small, and Medium Enterprises) Act in 2006. As a result, all the small and micro industries were placed under the MSME Act.  Because of the bill passed by the government, both SSI and MSME became the same. By implication, the government enlarged the scope of the SSI and termed it MSME.
