Duty drawback rates for silk products adjusted, specifying new unit-based rates and applied retrospectively to earlier exports. Amendment to Notification No.29/2001-Cus.(N.T.) revises unit-based duty drawback rates for silk goods: it substitutes the Chapter 50 entry to fix a per square metre rate for fabrics made wholly or predominantly of silk (allocated to all customs) and inserts Chapter 62 entries setting unit-based rates for natural silk readymade garments with embroidery, handloom/powerloom silk lungies, and made-up silk articles. The notification deems the changes effective from 26th November, 2001.
