Actually, I am not satisfied to this answer. I also want to 
know the details answer of the same Q.

commercial invoice and excise invoice also maintain excise 
and vat. But also excise modvat, vat(local)  on take excise 
invoice and commiercial invoice take vat do not take excise.

Excise Invoice gives the entire details of tax as in if i 
am purchasing goods from a trader 100 nos., but he had 
purchased 1000nos. from manufacturer. My excise invoice 
will show even the details regarding the no. of goods 
purchased by the trader which is 1000 nos. & excise duty 
charged to him by the manufacturer & of which same will be 
charged to me for 100 nos. i.e. the trader will recover 
excise of the same amt. from me which he had paid to the 
manufacturer. These details of Trader is not shown on the 
commercial invoice.
