They have also raised the issue with Finance Minister Arun Jaitley and Steel Minister Narendra Singh Tomar.
The manufacturers, including L&T, Godrej, Thermax, Praj Industries, Aker Solutions, Toyo Engineering, ThyssenKrupp Industrial Solutions (India) have expressed serious concern at the "perpetual protectionist environment" in favour of the steel sector without consulting capital goods players.
"India is in the process of globalising its manufacturing base through establishment of capital equipment and downstream industries in MSME to generate employment as well as boost 'Make in India' through competitiveness of Indian products," PPMAI secretary VP Ramachandran was quoted as saying in a release.
Ramachandran pointed out that the recent proposal of the government to impose minimum import price (MIP) on steel products "without discussing all the stakeholders" will further create confusion.
