Activity in the UK Global Tariff on 24 June was dominated by a vast number of updates to customs duties for iron and steel. Over 1,800 changes were detected, overwhelmingly concentrated in HS Chapters 72 and 73, though these did not include any new trade defence measures. In a separate development, regulators loaded three new tariff rate quotas applicable to all origins, which are scheduled to take effect on 1 July 2026.
The themes
The dominant theme on 24 June was a large-scale update to the tariff structure for iron and steel. Of more than 1,800 change records detected, nearly all were concentrated in HS Chapters 72 (Iron and steel) and 73 (Articles of iron or steel). The changes primarily involved adding new measures and components to the existing tariff framework, suggesting a significant administrative restructuring rather than a simple shift in duty rates.
Notably, this wave of activity did not include any new anti-dumping or countervailing duties. Beyond the steel sector, the day’s changes were minimal, consisting of a handful of duty suspensions, minor nomenclature updates, and three new tariff quotas.
Headline items
Three new tariff rate quotas were established, applicable to imports from all countries. While the specific products covered were not detailed in the data feed, these quotas are a significant development for importers, creating new opportunities for reduced-duty access to the UK market. They are scheduled to become active next week.
The sheer volume of changes in the steel sector, while not tied to trade defence, represents the day's other major event. This appears to be a foundational update to customs duty measures affecting a broad range of iron and steel products.
Coming into force
No new measures took effect on 24 June.
Looking ahead, the most significant measures loaded are the three new tariff quotas, which will become effective on 1 July 2026.
What to watch
The immediate priority for firms trading in iron and steel will be to review the updated tariff landscape to ensure their product classifications and duty calculations remain accurate. The high number of 'already in effect' changes suggests these may be corrections or consolidations of existing rules. For other importers, the key development is the opening of the three new global tariff quotas next week; details of the specific products and quota volumes will be critical to watch for.
