Advance-ruling jurisdiction under section 97(2) does not extend...

Advance-ruling jurisdiction under section 97(2) does not extend to eligibility for refund of unutilised input tax credit arising from an inverted duty structure; that question is therefore not admissible. Heading 4504 covers agglomerated cork with or without a binding substance, without limits on the binder's quantity or nature. Cork sheets formed from agglomerated cork granules held together by a polymer system, rather than cork used merely as a rubber filler, fall under tariff item 4504 10 10 and qualify for the concessional GST entry. The bar applies only where the same question is pending or decided in proceedings concerning the applicant; absent such proceedings, classification and rate questions remain admissible.
