Manufacturing and trading

using seperate place of business and godowns for trading goods is preferred, 

as under excise, where the goods are manufactured, no duty paid goods are allowed to enter, which are not to be used in manufacturing, department may lead to conficsation of such goods if found within the area of manufacturing. 

as excise is matter of manufacturing mainly, so its always better not to do trading with same establishment, however if the assessee want to do so, then its must not to use the manufacturing yard for trading purpose.

Mr. Pandey,

There is single problem in your case that you can do trading and manufacturing  in under the same floor, but can do one another thing that you made another firm on which you send you raw material for job work pupose and take back after that you can do trading of the same product as per this you doest be registered and trade your manufactured product
