ABB — abnormal fixation of price regardless of international price

We are working in a government organized power sector. While trying to procure any items from mnc companies like abb or siemens india limited firms, they quote abnormal price against those products. While comparing those prices with international market, it has huge marigin (Variation may be 3 times higher than the actual cost). They are simply reasoning the importing procedure that lead to that much cost.
Is there any regulation to fix the price for commodity?
Who are governing those mncs?
By this way they are completely scrubbing indian money
As a indian i could not tolerate it.
You please take it as a common complaint against all international companies in india and make arrangement to regularize price marigin to those companies.
