A five-year trade barrier has been finalized. In June 2026, Pakistan's National Tariff Commission issued a final affirmative anti-dumping ruling on Chinese purified terephthalic acid (PTA), imposing duties ranging from 4.17% to 9.50%, retroactively effective from January 4, 2026. This means that for the next five years, Chinese PTA exports to Pakistan will carry an additional cost burden, and the differential rates among companies serve as a benchmark for export compliance.
Background
The final ruling concludes the ADC70 case, which began on August 16, 2025, when Pakistan initiated an anti-dumping investigation into Chinese PTA. The investigation period was clearly defined: the dumping probe covered April 2024 to March 2025, while the injury assessment extended from April 2022 to March 2025, a three-year span intended to fully evaluate the impact of imports on the domestic industry. On January 4, 2026, Pakistan issued an affirmative preliminary determination and imposed provisional duties, which were replaced by the final measures four months later.
The duty structure adopts a company-specific approach. INEOS Aromatics Asia Limited and its affiliated producer INEOS Zhuhai Chemical Co., Ltd. face a lower rate of 4.17%; Zhejiang Dushan Energy Co., Limited was assigned 9.50%; and all other non-individually-examined exporters and producers are subject to the same 9.50% rate. The product scope covers PTA under Pakistan HS code 2917.3610, with clear definitions.
Industry Impact
PTA is a core raw material for the polyester chain, and China is the world's largest producer and exporter. Pakistan is a key South Asian market for Chinese PTA. The anti-dumping duty directly raises the price of Chinese PTA in Pakistan, weakening its competitiveness. In the short term, profit margins for exporters—especially SMEs facing the 9.50% rate—will shrink, with per-ton costs rising by tens of dollars, eroding price advantages.
More profound is the reshaping of the industry landscape. Companies with lower duties, such as the INEOS affiliates, have gained a competitive edge through standardized pricing and complete responses to questionnaires. Higher-duty firms face a dilemma: absorb costs or redirect exports to other markets. This differentiated tariff structure effectively uses trade remedies to push Chinese PTA exporters toward better compliance, transparent pricing, and more rigorous trade procedures.
For buyers, downstream Pakistani users—producers of polyester filament, staple fiber, and bottle chips—will face higher raw material costs. In the short term, some costs may pass through to finished textiles, affecting the existing division of labor in the China-Pakistan textile chain. In the long run, Pakistan's domestic PTA industry may gain breathing room, but if its capacity and quality cannot effectively substitute imports, downstream industries will continue to bear the burden.
Practical Recommendations
For Exporters - Immediately verify the applicable duty rate (4.17% or 9.50%) for your PTA shipments to Pakistan to avoid customs delays or underpayment penalties. - Recalculate contract costs to include the anti-dumping duty, adjust pricing models, and consider sharing the burden with buyers or modifying payment terms to hedge against exchange rate and tariff risks. - Monitor NTC's subsequent administrative review or judicial appeal procedures; if you believe the ruling has procedural flaws, consider filing a joint review request with industry associations within the specified timeframe.
For Buyers - Pakistani PTA buyers should evaluate alternative supply sources, such as the Middle East or Southeast Asia, while considering logistics lead times and quality stability to avoid over-reliance on Chinese supplies. - For long-term contracts, include tariff adjustment clauses to address price changes if new measures are imposed, reducing contractual uncertainty. - Watch for shifts in Chinese exporters' strategies; some may redirect capacity to other markets, potentially tightening supply in Pakistan, so build safety stocks in advance.
Overall, this final ruling sets new rules for China-Pakistan PTA trade. Over the next five years, compliance capability will become a core competitive advantage, while market diversification and supply chain collaboration will be long-term strategies to navigate trade barriers.
