Registration and duty liability for articles of precious metals on job work now require assessees to register, account and file quarterly returns. Amendments require persons who get articles of precious metals produced on job work basis (excluding EOUs and SEZ units) to obtain registration, maintain accounts, pay duty leviable on such goods and comply with all relevant provisions as if they are assessees; rule 12's fourth proviso is revised to mandate quarterly returns of production and removal within ten days after quarter end for assessees availing specified exemptions, with transitional filing dates for certain quarters in 2016.
