Mandatory BIS standards for imports require specified goods to meet listed product standards under the amended import schedule. Amendment amends Schedule I (Imports) of the ITC(HS) Classification by revising Appendix III to prescribe Applicable BIS Standards for specified import items. The Appendix lists product categories-food and beverage items, cements, household electrical appliances and components, medical instruments, steel tubes, oil stoves, gas cylinders and fittings, LPG containers, diesel engines and related goods-each paired with a BIS standard number, thereby tying import classification and regulatory compliance to the listed BIS specifications.
