Pakistan Lifts Anti-Dumping Duties on Sulphonic Acid Imports

Pakistan’s National Tariff Commission (NTC) has formally lifted anti-dumping duties on sulphonic acid imports from China, India, Indonesia, Iran, Korea and Chinese Taipei, effective immediately, after concluding a sunset review.

The move was made under Section 58 of the Anti-Dumping Duties Act, 2015, in conjunction with Chapter VI of the Anti-Dumping Duties Rules, 2022.

The review focused on imports of Linear Alkyl Benzene Sulphonic Acid and was launched on May 23, 2025, following petitions submitted by local manufacturers Tufail Chemical Industries Limited and Ittehad Chemical Limited.

According to the NTC, the investigation evaluated market conditions over a three-year period spanning January 1, 2022 to December 31, 2024. The findings showed no likelihood of continued or renewed dumping by the subject countries if the duties were withdrawn.

The Commission further concluded that the domestic industry would not suffer material injury without the anti-dumping protection. Consequently, it determined that the continuation of duties was unwarranted.

Sulphonic acid, falling under Pakistan Customs Tariff Heading 3402.3100, is an essential input for manufacturing detergent powders, dishwashing liquids and various industrial cleaning products.

Based on these conclusions, the NTC directed the immediate termination of anti-dumping duties on sulphonic acid imports from the concerned countries.
