Customs duty schedule amendment revises tariff entries and exemption conditions to reallocate concessional import treatment for specified inputs. Amendment revises the exemption notification by substituting preamble text, modifying provisos on effective dates, omitting multiple Table entries, and replacing or inserting numerous tariff lines with new duty treatments tied to use or grade. It deletes specified Annexure Conditions, omits selected Lists, and expands List 3 by inserting multiple pharmaceutical substances and diagnostic items, thereby realigning concessional import eligibility toward defined manufacturing and medical inputs under the amended exemption framework.
