Product description: Para-Tertiary Butyl Phenol or PTBP, inclusive of molten and flaked forms.
Uses: PTBP is mainly used to manufacture a perfumery raw material para tertiary butyl cyclo hexyl acetate (PTBCHA). Also used to manufacture a range of resins including epoxy, polycarbonate resins and phenolic resins.
HS Code: Under Chapter 29 (29071940)
Countries: China PR and Taiwan
Applicant: Vinati Organics Limited
Date of initiation: 26 June 2025
Period of Investigation: 01.04.2024 to 31.03.2025
Injury Period: 2021-22, 2022-23, 2023-24 and the period of investigation
Recommended duties and ranges –
| Producers | Dumping Margin (%) | Injury Margin (%) | Duty ($/MT) |
| Any producer/exporter (China PR) | 10-20 | 0-10 | 115 |
| Any producer/exporter (Taiwan) | 5-15 | 0-10 | 28 |
Key Findings –
- The product under consideration is “Para-Tertiary Butyl Phenol” or “PTBP”, conforming to CAS No. 98-54-4, inclusive of both molten and flaked forms.
- The Domestic Industry was materially retarded from establishing itself due to past effects of dumping from USA, Singapore and South Korea. Duties were imposed on these sources on 14.03.2024.
- Post imposition of duties on earlier sources, imports of PTBP from subject countries increased by 287% from base year to the POI.
- The cost of sales increased over the injury period whereas selling price declined and had been below the cost of sales throughout the injury period.
- Landed price of subject imports was below non-injurious price and prevented Domestic Industry from increasing its selling price.
- There is a demand-supply gap, however, domestic industry was prevented from selling higher volumes due to imports from subject countries and was therefore, forced to export to other countries.
- Despite increase in demand, inventory levels increased by 30% over the injury period.
- The Domestic Industry incurred losses, cash losses and significant negative return on capital employed throughout the injury period.
- The dumping and injury margin determined from producers/exporters from subject countries is positive and significant.
- Impact of recommended duty on the downstream perfumery and resin industry is less than 0.1%
