Electronics Regulation Compared: EU vs UK vs US

One of the most consistent sources of electronics compliance risk is the assumption that certification or approval in one market transfers to another. It does not. The EU's CE marking framework, the UK's post-Brexit regulatory landscape, and the US FCC and CPSC regime are built on fundamentally different legal structures, conformity assessment procedures, and enforcement mechanisms. Understanding the distinctions before market entry is considerably less expensive than resolving them after a market surveillance action or border rejection.

The comparison below covers the eight most commercially significant compliance dimensions for electronics manufacturers entering or already operating across the EU, UK, and US. Where the 2025-2026 regulatory changes materially affect a category, these are noted.

At a Glance: EU vs UK vs US Electronics Compliance

The Critical Differences That Create Compliance Risk

CE Marking Does Not Satisfy FCC Requirements - and Vice Versa

The most common structural misunderstanding in electronics market entry planning is treating CE marking and FCC authorisation as equivalent or interchangeable. They are not. CE marking under EU directives certifies conformity with European harmonised standards. FCC authorisation under 47 CFR Part 15 certifies conformity with US radiofrequency emission limits and, for intentional radiators, requires pre-market approval through an FCC-recognised Telecommunications Certification Body. A product with CE marking cannot be placed on the US market without separate FCC authorisation. A product with FCC certification cannot be CE marked on that basis. Both processes must be completed independently, typically in parallel during product development.

UK CE Recognition Has No Guaranteed End Date - But Is Not Permanent

The UK government's indefinite extension of CE mark recognition for Great Britain is pragmatic but carries risk for long-term planning. "Indefinitely extended" does not mean permanently guaranteed - the government can change its position, and manufacturers who have relied entirely on CE marking without maintaining UKCA-compatible technical documentation could face a compliance gap if the policy changes. Northern Ireland requires CE marking under the Windsor Framework regardless of any GB policy changes. The safest approach is to maintain documentation that satisfies both CE and UKCA requirements simultaneously, even if only CE marking is currently required for the GB market.

Cybersecurity Is Now Mandatory in the EU and UK, Voluntary in the US

The EU RED cybersecurity requirements (Articles 3.3(d)(e)(f), activated by Delegated Regulation (EU) 2022/30) entered into force on 1 August 2025 and are mandatory for all radio equipment newly placed on the EU market. The UK's PSTI Act 2022 has imposed three baseline cybersecurity requirements on connectable consumer products since April 2024. By contrast, US federal IoT cybersecurity requirements remain largely voluntary as of early 2026 - the FCC Cyber Trust Mark is a market differentiation tool, not a compliance obligation. Manufacturers targeting the EU and UK markets must plan and budget for mandatory cybersecurity conformity assessment; those targeting only the US have significantly less prescriptive obligations at federal level.

RoHS Has No US Federal Equivalent

EU RoHS (2011/65/EU) restricts 10 hazardous substances in EEE, with mandatory compliance as part of CE marking. UK RoHS (SI 2012/3032) mirrors the EU framework with independent enforcement by OPSS. The United States has no equivalent federal legislation. California's Proposition 65 requires consumer warnings for products containing listed chemicals, and state-level electronic waste schemes impose take-back obligations, but there is no national RoHS-equivalent mandatory substance restriction. Manufacturers exporting to the EU and UK must maintain full RoHS compliance documentation; those selling only into the US do not face the same federal substance restriction framework, though state-level rules require monitoring.

What Changes in 2025-2026

The August 2025 RED cybersecurity enforcement date is the most significant recent change to the EU compliance landscape. Products with any radio functionality - Wi-Fi, Bluetooth, Zigbee, cellular, or other - that are newly placed on the EU market must now have cybersecurity conformity assessed and documented against harmonised standards EN 18031-1/2/3, published January 2025. Products CE-marked before August 2025 that continue to be manufactured and sold require updated Declarations of Conformity to include the cybersecurity provisions.

The RoHS exemption non-renewals (Delegated Directive EU 2025/2364 — 6(a) for lead in steel, expiring December 2026; 6(b) for lead in aluminium, expiring through to June 2027) are the second most significant change, creating reformulation obligations for manufacturers using these materials in mainstream EEE product categories. The Cyber Resilience Act (Regulation EU 2024/2847)'s December 2027 applicability date means that manufacturers investing in RED cybersecurity compliance now should plan that compliance programme with CRA transition in mind - the scope expands from radio equipment to all products with digital elements.
