2.39%-15.00%! Pakistan’s final anti-dumping ruling on Chinese polyester staple fiber takes effect, continuing a decade-long dispute for another five years

Chronology of Investigation

As early as April 2015, Pakistan initiated an anti-dumping investigation on this type of polyester staple fiber. In October of the same year, it began imposing anti-dumping duties ranging from 2.82% to 11.51%, with the first round valid for five years. Upon the expiration of the duty period, two major domestic synthetic fiber manufacturers in Pakistan, Lucky Core Industries Limited and Ibrahim Fibers Limited, submitted a review request. The Pakistan Tariff Commission launched the first sunset review in 2020, simultaneously combining it with a changed circumstances review. In 2021, a ruling was made to maintain the original duty rates, extending the anti-dumping measures for another five years, while terminating the changed circumstances investigation due to insufficient supporting materials.

As the previous duty cycle neared its end, these two domestic enterprises again submitted a review request at the end of July 2025. Pakistan officially filed the case on September 20 of the same year, marking the second sunset review. After nearly a year of investigation and evaluation, Pakistan ultimately issued a positive final ruling, continuing the anti-dumping measures and updating the applicable duty rates. This ruling also includes a practical arrangement: for orders cleared after October 2, 2025, if there is a discrepancy in duty rates, domestic exporters can notify Pakistani importers to apply for a refund with the local customs. Enterprises need to proactively coordinate with overseas clients and local customs channels, organize complete documentation including shipping orders, customs declarations, and tax payments, and promptly process tax refunds to minimize unnecessary capital occupation and additional costs.

Impact on the Textile Industry

Pakistan’s textile industry is a pillar of its national economy, and domestic polyester staple fiber production capacity is concentrated in a few leading factories. Manufacturers repeatedly apply for sunset reviews, with the core purpose of using tariffs to raise the import cost of Chinese products and protect the domestic raw material market share. The involved 2 denier and below polyester staple fibers are basic spinning raw materials, with a high degree of product homogeneity, making them naturally prone to trade remedy investigations.

Subsequent quotations to Pakistan must take tariff factors into account. Compared to suppliers from other countries, our price advantage is significantly weakened, and many low-margin orders will face a risk of loss. Although Pakistan has traditionally been a destination for exported domestic polyester staple fibers, under the backdrop of prolonged trade protection measures, the business risk of relying on a single market is continuously rising. Enterprises cannot keep focusing solely on this market and need to steadily develop other overseas markets such as the Middle East and Southeast Asia to diversify export risks. The fact that anti-dumping duties were maintained in two consecutive sunset reviews also sends a very clear signal: as long as the domestic industry raises demands, a review may be initiated again even after the five-year period expires.

Strategic Response & Action Plan

Faced with this situation, export enterprises must first accurately grasp the boundaries of the products involved in the case, clearly distinguish between tariff codes and fineness indices, and avoid having products that are not within the scope of the current investigation mistakenly taxed during customs clearance. In business contracts, they should also predetermine terms related to the bearing of tariffs and cooperation on tax rebates, clearly defining the rights and responsibilities with overseas clients to prevent subsequent disputes.

For existing customers, enterprises can communicate flexibly based on order profitability; high-quality, stable long-term customers can negotiate to share tariff pressures, while small orders with thin or volatile profits should be undertaken cautiously, avoiding blind acceptance of orders. The industry can also maintain information exchange to promptly update on the latest developments in filings and rulings. In the event of future reviews, joint defense efforts among peers often prove more effective than dealing with cases individually.

Overall, the ADC33 case is not a temporary short-term restriction but a continuation of trade protection measures spanning over a decade. In the short-term business operation, the focus should be on risk control. In the long term, it is still necessary to rely on export market diversification and product structure upgrades to gradually offset the impact of such persistent trade barriers.
