The European Commission has doubled its anti-dumping duties on optical fibre cables from China, following an investigation which found that Chinese exporters of optical fibre cables were attempting to impede the effects of the original measures. Commission Implementing Regulation (EU) 2025/1135 of 10 June 2025 imposing a definitive countervailing duty on imports of optical fibre cables originating in India and amending Implementing Regulation (EU) 2024/3014 imposing a definitive anti-dumping duty on imports of optical fibre cables. China has slapped American fibre-optic firms with anti-dumping tariffs – a move announced hours after the US Treasury imposed sanctions on a Guangzhou-based chemical firm, over fentanyl claims. The duties, ranging from 33. 2 per cent, went into immediate effect and are to remain in place. On September 3, the Ministry of Commerce announced the ruling on the anti-circumvention investigation into imports of certain cut-off shifted single-mode optical fiber originating from the United States. The companies involved include Corning, Draka Communications, and OFS-Fit. The ministry said in a notice that it has learned that.
