Exemption for crust leather: specified tariff codes now attract nil export duty under amended customs notification. The notification amends an earlier customs notification by substituting descriptive entries for specified serial numbers covering tanned hides and skins of bovine, equine, sheep, lambs and other animals (excluding E.I. tanned leather), and inserts a new serial entry identifying tariff headings for crust leather, with a nil export duty applicable to those headings; the amendment is enacted under customs authority and comes into force on the stated commencement date.
