Dear Expert, I have a query please help me. For Eg: Mr A gives the order for 100 grams Jewellery to Mr. B, and the same was given as Job work to Mr. C. Here Mr. B supplies the 100 grams & other stones required to Mr. C. After jewellery making Mr. C returns the jewellery which weights 92 grams and 8 grams as wastage in making. On how many grams do I apply excise duty? Now how do I show the wastage in the excise return.
