China will continue to impose anti-dumping duties on imports of single-mode optical fibre from India, according to a report by the Economic Times. The decision follows a sunset review initiated a year ago, which concluded that terminating the anti-dumping measures could lead to the continuation or recurrence of dumping and harm to China's domestic optical fibre industry. The duties, which were first implemented in August 2014 and extended for five years in 2020, will remain in effect with the same tax rates, ranging between 7.4% and 30.6% across different Indian exporters.
Sunset review findings
The Economic Times reported that the sunset review concluded that ending the anti-dumping regime would likely cause the continuation or recurrence of dumping. The review also identified potential harm to China's domestic optical fibre industry. Based on these findings, the measure is being maintained. The review was initiated one year ago relative to the August 13, 2026, report date.
Duty schedule for Indian exporters
The duty rates will remain unchanged from previous rulings, according to the Economic Times. Sterlite Technologies is named in the report with a duty rate of 7.4%. Aksh Optifibre and Finolex Cables are both named with a duty rate of 30.6%. The report states that the range across different Indian exporters is 7.4% to 30.6%.
| Indian Exporter | Duty Rate |
|---|---|
| Sterlite Technologies | 7.4% |
| Aksh Optifibre | 30.6% |
| Finolex Cables | 30.6% |
According to the Economic Times, all three companies are among the Indian exporters affected by the duties, and the rates listed are unchanged from the previous rulings.
Chronology of the measure
- August 2014: China first implemented anti-dumping duties on Indian single-mode optical fibre.
- 2020: The duties were extended for a five-year period.
- 2026: Following the latest sunset review, China decided to keep the duties in place with unchanged rates.
Key finding from the review
The Economic Times reported that terminating the anti-dumping measures could lead to the continuation or recurrence of dumping and harm to China's domestic optical fibre industry.
This finding was the basis for keeping the duties in force. The report does not indicate any changes to the scope of products, the list of exporters, or the applicable rates.
What this means for trade professionals
For importers and customs brokers, the practical implication is that anti-dumping duties on Indian single-mode optical fibre entering China will continue to be collected at the existing rates. Exporters covered by the measure need to maintain their classification for duty assessment. The rate spread between the lowest (7.4%) and highest (30.6%) remains wide, and the specific rate assigned to each Indian exporter determines the final duty paid. Since the duties have now been in place since 2014, with an extension in 2020 and a continuation in 2026, the measure spans more than a decade of bilateral trade between China and India in this product category.
