CBIC has issued Instruction No. 12/2026-Customs directing Customs formations to provisionally assess imports of “Insoluble Sulphur” originating in or exported from China pending the outcome of an anti-absorption review initiated by the Designated Authority. The instruction follows Notification No. 13/2026-Customs (ADD), issued under the Anti-Dumping Rules, 1995. The Designated Authority has indicated, on a prima facie basis, that an increase of approximately USD 170–180 per metric tonne over the existing anti-dumping duty may be warranted. Accordingly, Customs officers have been instructed to obtain sufficient guarantees from importers to cover any potential increase in anti-dumping duty during provisional assessment. The guarantee is to be furnished in addition to the anti-dumping duty already imposed under Notification No. 13/2025-Customs (ADD), which will continue to be levied. CBIC has also directed field formations to sensitize officers and ensure strict compliance with the instruction until the review is concluded.
