50% Steel Tariffs, India FTA & HMRC's Customs Overhaul
Sometimes the biggest customs changes don't arrive with months of warning.
They arrive on the first day of the month.
This week in The Customs Watch UK, UK businesses face one of the most significant changes to steel imports in recent years.
From 1 July, the UK's new steel trade measure is now fully operational. Tariff-free quotas have been reduced by more than half, while imports exceeding the available quota now face a 50% tariff; double the previous rate.
At the same time, businesses trading with India have less than two weeks to prepare for one of the UK's largest Free Trade Agreements before it enters into force on 15 July.
Meanwhile, HMRC has quietly published perhaps its most important customs policy update of the year, setting out eleven measures that will modernise customs over the coming years through AI border checks, digital trade documentation and mandatory intermediary registration.
What Is Covered In This Week's The Customs Watch UK?
🚨 UK Steel Rules Have Changed Overnight
The UK's steel safeguard regime has officially ended.
In its place comes an entirely new steel trade measure that significantly reduces tariff-free quota volumes while increasing above-quota duties to 50%.
For businesses importing steel, landed cost calculations may already have changed.

🇮🇳 UK–India FTA Arrives on 15 July
One of the UK's largest trade agreements is almost here.
The UK–India Free Trade Agreement enters into force on 15 July, liberalising 99% of UK tariff lines and creating significant opportunities for importers and exporters.
Businesses wishing to claim preferential treatment should ensure they are prepared before implementation day.

🤖 HMRC Signals the Future of UK Customs
HMRC's 2026 Tax Update contains much more than administrative changes.
It outlines eleven measures that could reshape UK customs over the coming years.
These include:
AI-assisted border checks
Electronic Trade Documents
Digital trade credentials
Mandatory customs intermediary registration
Low-value import reforms
The Customs Watch UK this week offers perhaps the clearest indication yet of where UK customs administration is heading.
🇺🇸 U.S. Anti-Dumping Registration Raises New Risks
Importers of U.S. polyethylene now face a new compliance challenge.
The UK has introduced registration requirements for certain polyethylene imports while anti-dumping investigations continue.
Should definitive measures eventually be imposed, duties could potentially apply retroactively for up to 90 days.
