After a four-year investigation and two rounds of rulings, the trade environment for China's pure terephthalic acid (PTA) exports to Pakistan has fundamentally changed. On June 12, 2026, Pakistan's National Tariff Commission issued the final determination in case ADC70, imposing anti-dumping duties on Chinese PTA for five years, with rates differentiated by company: 4.17% and 9.50%. This means that from January 4, 2026, all covered PTA exports to Pakistan must pay additional duties at the corresponding rates, signaling the end of the low-price, high-volume era for Chinese chemical fiber feedstock in the Pakistani market.
Background
The final ruling covers pure terephthalic acid under Pakistan Customs tariff code 2917.3610. The rate structure is clearly tiered: INEOS Aromatics Asia Limited and its affiliated producer INEOS Zhuhai Chemical Co., Ltd. benefit from a lower 4.17% rate, while Zhejiang Dushan Energy Co., Limited and all other non-individually determined exporters and producers face a uniform 9.50% rate. This differentiation is not arbitrary; it is based on each company's export pricing and dumping margins during the investigation period from April 1, 2024, to March 31, 2025.
Tracing the case timeline, Pakistan initiated the investigation on August 16, 2025, with an injury assessment period spanning April 1, 2022, to March 31, 2025. A preliminary affirmative determination on January 4, 2026, triggered provisional duties for four months, now replaced by the final measures with retroactive effect. From initiation to final ruling, the case took less than ten months—a notably faster pace than most trade remedy cases—reflecting Pakistan's urgency to protect its domestic PTA industry.
Industry Impact
The tiered rates have divergent effects on Chinese companies. The 4.17% rate means INEOS Aromatics and its Zhuhai plant face limited cost increases, preserving their price competitiveness. In contrast, the 9.50% rate burdens most small and medium exporters, adding roughly $40–60 per ton in tariff costs based on current international PTA prices, directly squeezing profit margins. For firms relying on Pakistan as a core market, this may force order repricing or even loss of low-margin orders.
Structurally, the impact runs deeper. Pakistan is a major overseas buyer of Chinese PTA, and this five-year measure shifts competition from price to compliance. Low-duty companies gain a stable tariff advantage through standardized pricing and transparent trade practices, while high-duty firms must choose between absorbing costs or pivoting to other markets. Public trade data show China's PTA capacity exceeds 80 million tons, with slowing domestic demand making overseas markets increasingly vital. The Pakistani policy shift may accelerate diversification into Southeast Asia, the Middle East, and Africa.
Practical Recommendations
For Buyers - Recalculate total landed costs including duties, and clarify with suppliers who bears the anti-dumping tax to avoid unexpected charges at the port. - Prioritize suppliers with lower duty rates (e.g., INEOS Aromatics) to lock in cost advantages. - Monitor Pakistani customs enforcement details for tariff code 2917.3610, ensuring complete documentation and smooth clearance.
For Trading Companies - Review order pricing for Pakistan against the final rates and adjust quotes to prevent margin erosion. - Strengthen export compliance, maintain thorough pricing and transaction records, and prepare evidence for potential reviews or new investigations. - Diversify market exposure by expanding into Southeast Asia, the Middle East, and Africa to reduce dependence on a single market.
The five-year anti-dumping duty serves as a mirror, reflecting both the rough edges of China's PTA exports and the resilience of compliant firms. In an era of normalized trade friction, treating compliance as a core competitive advantage is the key to standing firm behind tariff walls.
