British Beauty Brands Now Face Three Different Rulebooks, and That's Before the Tariffs

A cream that clears UK shelves can still sit blocked at customs bound for the EU, and the reason has nothing to do with the formula. It comes down to paperwork that didn't exist five years ago.

Before Brexit, a single filing through the EU's Cosmetic Products Notification Portal cleared a product for sale across the whole bloc, UK included. Great Britain now runs its own system, the Submit Cosmetic Product Notification service, overseen by the Medicines and Healthcare products Regulatory Agency. A brand selling into both Great Britain and the EU has to notify the same product twice, through two separate portals, and appoint a UK-based Responsible Person to handle the GB filing on top of whatever representation it already holds in the EU.

The ingredient rules behind those filings are starting to diverge as well. Great Britain banned the UV filter 4-methylbenzylidene camphor under SI 2026/23, a restriction the EU doesn't carry in the same form. Each divergence like this means a formulator checks a product against two rulebooks instead of one. Some brands now run two versions of the same formula to stay compliant in both markets.

Northern Ireland adds a third layer. Under the Windsor Framework, the EU's Cosmetics Regulation (EC 1223/2009) continues to apply there even as Great Britain follows its own rules, according to guidance from the Cosmetic, Toiletry and Perfumery Association. A brand based in Manchester selling into Belfast is, for regulatory purposes, exporting into an EU-rules market. Whether cosmetics will eventually carry the 'Not for EU' labelling already applied to food and drink under the Windsor Framework is still unsettled. Brands are waiting on further guidance from the Department for Business and Trade before they commit to relabelling runs.

Oxford Economics, in analysis commissioned by the British Beauty Council, put the cumulative toll of this new border on UK beauty exports to the EU at more than £850m lost since the 2016 referendum. The Council called the result one that should make the government blush, pointing to customs delays and added compliance costs as the drivers rather than any drop in demand for British products abroad.

Then came the tariffs. The United States applied a 10 percent baseline tariff on UK goods in April 2025, and the British Beauty Council flagged a complication specific to this industry. Much of UK beauty manufacturing runs through supply chains that pass through the EU, China, Japan, South Korea and Southeast Asia before a finished product ever reaches a US shelf. The Council has pressed the Treasury on three open questions: whether the US tariff stacks on top of existing duties, how 'substantial transformation' gets defined for a product assembled across several countries, and whether the de minimis import threshold will be reformed to stop cheaper foreign goods flooding the US market duty-free while UK shipments pay in full.

A second, quieter tariff problem sits with Canada. The UK-Canada trade continuity arrangement let UK exporters use EU-origin ingredients and components while still claiming zero tariffs, under a cumulation clause carried over from the UK's old EU membership. That clause is set to expire. A UK brand that formulates with EU-sourced ingredients and ships finished product to Canada could face full most-favoured-nation tariffs on exports that cleared duty-free a year earlier, with no change to the product itself.

None of this falls evenly across the industry. Beauty Independent's reporting on US tariff exposure describes large multinationals absorbing new costs through diversified manufacturing bases and pricing power built up over decades. A small indie brand formulating in a single facility, filing through a single Responsible Person, and selling direct to US customers at a fixed retail price doesn't have the same room to move. For that brand, a 10 percent tariff lands directly on margin, and a second SCPN filing for a new EU ingredient restriction lands directly on legal fees it has to pay before a single unit ships.
