The European Union’s customs tariff saw a week of sharp contrasts, defined by a dual narrative of liberalisation and targeted restriction. While a massive, scheduled expiration of long-standing anti-dumping duties on chemicals and fish took effect, new regulatory activity was intensely focused on tightening controls in strategic sectors. Over 2,600 trade defence records were logged as regulators introduced new surveillance measures and duties for steel and plastics, primarily targeting imports from China and Türkiye.

The week in brief

The week's high volume of regulatory movement, with over 3,400 change records detected and nearly 4,000 measures taking effect, was driven by two opposing forces. On one hand, a significant liberalising shift occurred as a large number of anti-dumping regimes expired on 1 June, opening the market for key chemicals and Turkish trout. On the other, the EU demonstrated a highly focused tightening posture in strategic industries. The iron and steel sector was the overwhelming center of new regulatory action, seeing thousands of updates aimed at managing imports, while the plastics sector saw swift new protective measures, indicating a clear policy of strategic realignment rather than a simple shift toward or away from protectionism.

What mattered most

Three key developments defined the week's activity:

  • Mass Expiry of Anti-Dumping Duties: A major liberalising event occurred as numerous long-standing anti-dumping measures expired on 1 June. This removed duties on a range of industrial chemicals, including adipic acid from China and acrylates from multiple origins such as China, the United States, and South Africa. Duties also lapsed on various presentations of trout originating in Türkiye, reshaping import conditions for these products.

  • Intensified Scrutiny on Steel: The iron and steel sector was the subject of a concerted regulatory campaign. New surveillance measures, in the form of information requirements, were imposed on steel grill, netting, and fencing from China, Türkiye, and on an all-countries basis, effective 3 June. In parallel, regulators loaded significant future anti-dumping duties on hot-rolled steel products from Türkiye, with rates as high as 7.3% set to take effect on 1 July. This tightening was balanced by the introduction of new 0% duty tariff quotas for a range of flat-rolled steel products from South Korea.

  • Rapid Action on Chinese Plastics: Regulators moved with unusual speed to control imports of certain aliphatic-aromatic copolyesters (PBAT and PBSeT) from China. An information notice requiring the registration of imports from China and all countries took effect on 4 June, a common precursor to a formal investigation. This was immediately followed by a new 6.5% customs duty on the same products from all origins, which became effective on 5 June.

Threads to watch

The week's actions set several key storylines in motion for the coming months. The implementation of broad surveillance on specific steel products is a strong signal of increased scrutiny, and such measures are often the first step toward definitive duties. Importers of these goods from China and Türkiye should anticipate more rigorous compliance demands. The 1 July effective date for the updated Turkish steel duties is the next critical milestone for operators in that supply chain. Similarly, the rapid escalation from surveillance to a definitive duty on copolyesters suggests that plastics and chemicals remain a high-priority area for EU trade defence, and the market reaction to the expired duties on other chemicals will be closely monitored by authorities.
