Anti-dumping duty continuation on Styrene Butadiene Rubber imports extended under domestic tariff law by government notification after review. The Central Government amends the principal customs notification to extend the continuation of anti-dumping duty on Styrene Butadiene Rubber (SBR) 1900 series imports originating in, or exported from, Japan, Korea RP and the United States by adding a clause that the notification shall remain in force up to and inclusive of the specified terminal date unless revoked earlier, thereby preserving the existing anti-dumping regime following the statutory review and request for extension.
