EU imposes anti-dumping duties of up to 24.1% on terephthalic acid imports
10 August 2026
On 10 August 2026 the European Commission confirmed definitive anti-dumping duties on EU imports of terephthalic acid from South Korea and Mexico. Duties on Korean imports range from 6.1% to 13.3%, while Mexican imports face a 24.1% duty. The case is a strong protectionism example because it shows a targeted tariff-style measure intended to defend EU producers from dumped imports while creating potential costs for downstream users.

What happened
The European Commission imposed definitive anti-dumping duties after an investigation concluded that terephthalic acid from South Korea and Mexico had been entering the EU at dumped prices and causing injury to EU producers. The Commission set duties of 6.1% to 13.3% on Korean imports and 24.1% on Mexican imports. The EU market is worth about €1.4 billion and the domestic industry directly employs around 600 people in Belgium, Poland and Spain.
Why it matters
Anti-dumping duties are a form of protectionism designed to raise the price of selected imports when authorities conclude that foreign producers are selling below a fair benchmark and injuring domestic industry. For students, the case is useful because the policy has a clear benefit-cost trade-off: EU producers may gain market share and preserve employment, while manufacturers using terephthalic acid to make PET packaging, bottles and fabrics may face higher input costs.

Chain
Dumped imports enter at unusually low prices → anti-dumping duties raise the landed price of affected imports → EU producers become more price-competitive → domestic output may rise and imports may fall → downstream users face higher input costs → the welfare effect depends on whether correcting injurious dumping outweighs the costs of protection
Evaluation
Anti-dumping duties can protect domestic producers from unfairly low-priced imports, but they can also raise costs for firms using the protected product as an input. The net effect depends on demand and supply elasticities, alternative suppliers, the persistence of dumping and whether protection weakens competitive pressure over time.
