MVAT Schedule Rate on Domestic LPG Gas

The MVAT Rate of LPG Cylinders for Sale in Maharashtra upto 31/03/2006 was 12.50%.  But from April 2007 the manufacturer i.e. HPCL, BPCL, IOCL has started collecting VAT @ 4% on this products.  But I did not find any Entry in Schedule C for this product.

Can enbody help me in this respect.  Because in VAT Audit Report we have to report the Schedule Entry Number of the product sold.  The Company is not in position to clarify the matter.

Thanks in Advance
