The Official Journal L series for 21 April 2026 carries five substantive acts. The most commercially significant measure is the adoption of a new Technology Transfer Block Exemption Regulation, which renews the competition law safe harbour for patent and know-how licensing just as the previous regulation expired. Alongside it, a new implementing regulation opens the first tariff quotas under the EU-Mercosur trade deal, effective 1 May 2026. A chemical restriction under REACH targets a carcinogenic compound found in a range of industrial articles. An emergency decision updates avian influenza restriction zones in Denmark and Poland. Two delegated regulations complete the set, preserving existing technical classification systems in the construction and financial sectors.
New Technology Transfer Block Exemption Regulation (Commission Regulation (EU) 2026/877)
The Commission adopted a new TTBER replacing Regulation No 316/2014, which expired 30 April 2026. Competitors benefit from the block exemption up to a 20 percent combined market share; non-competitors up to 30 percent each. The regulation runs until 30 April 2038, with a transitional period until 30 April 2027 for existing agreements. Technology pools and licensing negotiation groups fall outside the scope.
First Mercosur Quotas Open as Trade Deal Takes Effect on May (Commission Implementing Regulation (EU) 2026/888)
Opening quotas cover infant formula (334 MT for 2026, 5,000 MT/year ceiling by 2036, duty-free), Mercosur rum (267,000 litres for 2026, 2.4 million litres/year from 2031, 100% reduction), and Paraguayan biodiesel (33,333 MT for 2026, 50,000 MT/year from 2027, 100% reduction). All quotas are first-come, first-served and require Mercosur origin certificates.
Cancer-Linked Chemical 2,4-DNT Banned From Consumer and Professional Products (Commission Regulation (EU) 2026/859)
Articles containing 2,4-dinitrotoluene at or above 0.1% by weight are banned for consumers and most professional users from 10 May 2027. Exemptions apply for explosives, military and police ammunition, medical devices, food contact materials, and toys. Automotive safety components (seat belt pretensioners, bonnet actuators) already on the market benefit from a 36-month transitional period running to May 2030.
ANIMAL HEALTH AND AGRICULTURE
Bird Flu Worsens After New Outbreaks Hit Denmark and Poland (Commission Implementing Decision (EU) 2026/896)
New outbreaks confirmed at a holding near Guldborgsund, Denmark (protection zone to 7 May 2026, surveillance zone to 16 May 2026) and across 10 holdings in three Polish voivodeships: Mazowieckie, Warminska-Mazurskie, and Wielkopolskie. Restriction zones now cover eight Member States: Bulgaria, Czechia, Denmark, Germany, France, Italy, the Netherlands, and Poland.
Hungary Anti-LGBTQ+ Law Violates EU Values: Full Court Upholds All Six Pleas (Case C-769/22, Full Court)
Sitting in its highest formation, the Court condemned Hungary’s 2021 law restricting content depicting homosexuality and gender identity for under-18s. The Full Court found breaches of Directive 2010/13 (audiovisual media), Directive 2000/31 (e-commerce), Directive 2006/123 (services), the GDPR, Articles 1, 7, 11 and 21 of the Charter, and (in a landmark first) Article 2 TEU itself. The Court ruled that Article 2 TEU is legally binding and actionable under Article 258 TFEU where a Member State commits a manifest and particularly serious breach incompatible with the Union’s identity as a common legal order.
Tobacco ISO Emission Standards: Access Defeats Non-Publication Argument (Case C-155/24, Grand Chamber)
The Grand Chamber answered the first of seven referred questions from the Dutch Supreme Administrative Court for Trade and Industry, holding that parties who in fact accessed the official and authentic versions of the ISO measurement standards referenced in Article 4(1) of Directive 2014/40 cannot invoke non-publication in the Official Journal to demand alternative cigarette emission testing. The remaining six questions were rendered unnecessary to answer. The Court confirmed that ISO standards made mandatory by EU law must in principle be freely accessible to individuals whose interests those laws protect.
Euroclasses Fire Classification Re-established Under New CPR Commission Delegated Regulation (EU) 2026/331
The fire performance classification system (A1-F, FL, L, and cable variants Aca-Fca) is carried over unchanged from Delegated Regulation (EU) 2016/364 and given a new legal basis under the replacement Construction Products Regulation (EU) 2024/3110. No retesting or reclassification is required.
Market Cap Methodology Defined for FASTER Withholding Tax Relief Commission Delegated Regulation (EU) 2026/110
Market capitalisation is calculated as outstanding shares multiplied by the volume-weighted average price of the last 100 transactions in the final five minutes of the last trading session of the year on the most liquid EU venue. The market cap ratio for each Member State equals that state’s total issuer capitalisation divided by total EU capitalisation. Issuers are attributed by their GLEIF legal address.
