Margins and recommended duties

Key Findings:

1. The product under consideration is Phthalic Anhydride
2. The present review investigation has established the continuation of dumping of the product, and the findings indicate that dumping is likely to persist should the duties be allowed to lapse.
3. The current position of the domestic industry is vulnerable due to dumping from subject countries.
4. Dumped imports from China PR and Korea RP are priced below the selling price of the domestic industry resulting in positive price undercutting.
5. Dumped imports have constrained the domestic industry’s ability to raise prices in line with rising costs. The resultant decline in domestic prices demonstrates the price-depressing effect of such imports on the domestic industry.
6. During the period of investigation, the domestic industry recorded financial losses, including losses before interest, cash losses, and a negative return on capital employed.
7. Producers in the subject countries except Thailand are operating with significant surplus capacities, indicating a strong likelihood of import volumes increasing upon expiry of the measures.
8. Subject Imports entering the domestic market except Thailand are likely to exert a price-suppressing and price-depressing effect on the domestic industry.
9. Third-country exports from the subject countries are also priced below their associated normal values.
10. Substantial quantity of exports from China PR and Korea RP to third countries are below the Non-Injurious Price.
11. There is no evidence to suggest that the duties in force have had any adverse impact on downstream industries. In fact, demand for the product has grown steadily over the period during which measures have been in place.
12. The continuation of measures is expected to have a negligible effect on downstream industries.
13. The anti-dumping duties have ensured a level playing field, which has catalysed substantial capacity investment in the domestic market. The historic demand-supply gap has since been bridged, with the industry having invested approximately ₹1,900 crore in new capacity.
14. Given that the domestic industry has suffered continued injury during the period of investigation, the extension of anti-dumping duties from China PR and Korea RP is warranted.
