Jute content threshold reduced for tariff exemption, narrowing eligibility for blankets, mats, carpets and related fabrics under central excise. The notification substitutes the previous jute fibre or yarn content threshold for jute blankets, mats, carpets, felt and printed, bleached and dyed jute fabrics with a lower threshold, thereby altering which products meet the stated tariff classification or exemption under Notification No. 50/90 Central Excises.
