Anti-dumping duty extension on Fluoroelastomers from China maintains duty and revises tariff classification under Customs Tariff Act powers. The Central Government, under sub-sections (1) and (5) of section 9A of the Customs Tariff Act and rules 18 and 23, amends the principal notification to substitute tariff figures '3904 90 00' with '3904 90 90' and inserts a paragraph providing that the anti-dumping duty on Fluoroelastomers from China shall remain in force up to and inclusive of the specified extended date unless revoked, superseded or amended earlier.
