The US Department of Commerce issued a preliminary anti-dumping determination on 4 November 2026 on N-cyclohexylbenzothiazole-2-sulfenamide (CBS) from China.
The preliminary dumping margin for Chinese producers and exporters is 285.94%, with a cash deposit rate of 281.69% after offsetting subsidies. The product falls under US HTS code 2934.20.8000.
A final determination is scheduled for 12 January 2027. Commerce initiated the anti-dumping and countervailing duty investigations on 28 May 2026.
CBS is a rubber accelerator used in tyre and rubber processing. The high preliminary margin significantly raises cost for US buyers sourcing Chinese material.
