1	China PR	40-50%	15-25%	$ 440 / MT

Key Findings –

1. The Authority restricted the review to China PR, as imports from Korea RP had ceased and there was no likelihood of recurrence of dumping and injury from Korea RP.
2. The product under consideration was same as determined in the final findings of the original investigation.  
3. Demand for the subject goods increased over the injury period.
4. The volume of imports was negligible during the period of investigation due to presence of anti-dumping duty but increased significantly post – POI period. As a result, the production, capacity utilisation and sales of the domestic industry improved after the imposition of anti-dumping duty and the industry remained profitable.
5. The Authority concluded that expiry of anti-dumping duties is likely to result recurrence of dumping and injury to the domestic industry.
6. The Chinese imports increased significantly post – POI on an annualised basis, in anticipation of the expiry of duty.
7. Chinese producers have a tendency of dumping subject goods in India, evident from the significant dumping margins determined in the past.
8. The Chinese producers are engaging in significant dumping in third countries as well, and are also exporting the goods at injurious prices to such countries.
9. India is an attractive market for Chinese imports. The volume of dumped and injurious Chinese exports to third countries were at prices lower than prices offered to India.
10. Chinese producers have significant production capacities which are likely to be diverted to India in the absence of anti-dumping duty.
11. Continuation of duties will ensure fair competition in the market.
12. SHS is merely a chemical additive, and continuation of duties would have negligible impact on downstream users.
