Taiwan MOENV Issues Non-Animal Testing Guidance for Skin Sensitisation Under Taiwan REACH
In May 2026, Taiwan’s Ministry of Environment issued new and updated guidance allowing chemical registrants to use non-animal alternative methods for skin sensitisation, skin irritation/corrosion and eye irritation testing under Taiwan’s chemical registration regime. This clarifies how OECD-aligned NAMs will be accepted in practice, reducing animal testing burdens while preserving compliance for future registrations and encouraging earlier investment in validated methods for Taiwan-bound products.
TaiwanSouth Korea Establishes Public–Private Task Force to Promote Animal-Free Chemical Hazard Assessment
In May 2026 South Korea created a 22-member public–private task force to accelerate animal-free methods for chemical hazard assessment and develop a national new approach methodologies (NAMs) strategy through 2035. This signals a strategic shift in Korean chemicals regulation toward validated non-animal data, so companies relying on traditional animal studies for regulatory hazard assessments should anticipate future legislative changes, new guidance, and capacity-building initiatives favouring NAMs.
South KoreaMinnesota House Introduces Bills on Tire Producer Stewardship and Severe Animal Testing Ban (HF 5129, HF 5131)
On 11 May 2026 the Minnesota House introduced bills to create a producer-funded tire recycling programme and to prohibit certain severe animal research procedures, both currently at first-reading stage. If enacted, these measures would tighten waste and research governance in Minnesota, requiring tire producers to finance end-of-life management and research organisations to redesign or relocate high-pain animal studies.
United StatesPortugal Adopts Decree-Law 96/2026 Transposing EU Rules on Animals Used for Scientific Purposes
Portugal has adopted Decree-Law 96/2026, published on 4 May 2026, amending its national framework and transposing Commission Delegated Directive (EU) 2024/1262 on the protection of animals used for scientific purposes.

European UnionUK Updates Animal Research Licensing Guidance On Batch Quality Control Naming
The UK Home Office has updated its animal research licensing guidance under the Animals (Scientific Procedures) Act 1986 to add a section on naming products and substances in batch quality control and regulatory toxicology testing, with subsections reorganised for clarity. Organisations running animal-based regulatory studies should review project licence applications and templates to ensure products and substances are named in line with the referenced policy so that authorisations, audits, and compliance assessments are not delayed or challenged.
United KingdomUK Parliament Bill Would Ban Animals in Medical Research From 2035
A UK Private Member’s Bill would require regulations to ban the use of animals in medical research from 1 January 2035 and mandate non-animal methods for testing medicines and medical devices. If progressed, this would force a substantial redesign of UK preclinical testing and regulatory evidence requirements, accelerating investment in non-animal methodologies and potentially disrupting existing R&D pipelines ahead of the 2035 cut-off.
United KingdomEU Commission Confirms 2029 Ban on Animal-Tested Detergents and Plans Chemical Testing Roadmap
The European Commission has confirmed that the revised EU Detergents and Surfactants Regulation will, from 23 September 2029, ban placing on the market detergents and surfactants that were tested on animals to meet its requirements, and will publish a roadmap in Q2 2026 to phase out animal testing for chemical safety assessments. This strengthens long-term expectations that REACH, the Biocidal Products Regulation and related frameworks will progressively remove animal testing, requiring companies to plan earlier for alternative data and non-animal safety assessment methods.
European UnionUK Government Confirms Removal of Rabbit Pyrogen Test and Clarifies MHRA/Home Office Policy
In April 2026, UK parliamentary written answers confirmed that the rabbit pyrogen test was removed from the British Pharmacopoeia in 2025 and set out MHRA and Home Office positions that restrict its use in the UK to tightly controlled, exceptional cases for non-UK regulatory requirements. This reinforces a wider shift towards non-animal testing methods for medicines and devices, signalling that companies should plan for alternative pyrogen and preclinical testing strategies and expect closer scrutiny of any remaining rabbit-based protocols.
