EU Battery Regulation 2023/1542 + PAS 63100:2025 Protective Case B2B Guide
EU Battery Regulation 2023/1542 entered force August 2023, with phased requirements through 2027-2030. PAS 63100:2025 specifies safety requirements for protective cases used to transport lithium-ion batteries by road, rail, sea, and air. Below is the 2026 B2B buyer + manufacturer guide covering scope, UN 38.3 testing, recycled content thresholds, carbon footprint reporting, and protective case design requirements.
EU Battery Regulation 2023/1542 Scope
Regulation (EU) 2023/1542 replaces the 2006 Battery Directive. Covers all battery types including LMT, EV, industrial, SLI, stationary, with phased requirements.
Effective: 17 August 2023 (entered force), with phased application 2024-2030+. Replaces Battery Directive 2006/66/EC.
Scope: All battery types placed on EU market — portable, LMT (Light Means of Transport = e-bikes / scooters), EV (electric vehicle), industrial, SLI (starter/lighting/ignition), stationary energy storage.
Lithium-ion batteries: Most relevant to protective case B2B buyers since Li-ion is dominant in portable electronics, power tools, medical devices, EVs.
Phase-in dates (2026 status): Carbon footprint declaration (LMT/portable Li-ion) by 2026. Recycled content minimums (Li-ion: 16% Co, 6% Li, 6% Ni by 2031) phased from 2027. Battery passport requirement for EV/industrial/LMT from 2027. Removal of portable batteries from collection scope update.
B2B relevance: EU-bound B2B orders of any lithium-ion product now require carbon footprint declaration. From 2027, battery passport (digital record) mandatory for industrial / EV / LMT.
Customs: Non-compliant batteries may be refused entry at EU border. EU Commission has enforcement guidance for customs.
Penalties: Member states set national penalties, typically 1-5% of annual turnover or EUR 100,000-500,000 per violation.
B2B recommendation: For 2026 EU-bound orders with Li-ion, verify carbon footprint data is on hand + recycled content disclosure.
UN 38.3 Lithium Battery Transport Testing
UN 38.3 (UN Manual of Tests and Criteria, Part III, sub-section 38.3) is the global mandatory test for lithium battery transport. Required for all lithium batteries shipped by air, sea, road, or rail.
UN 38.3 test series: T1 altitude simulation + T2 thermal test + T3 vibration + T4 shock + T5 external short circuit + T6 impact + T7 overcharge + T8 forced discharge. All must pass.
Altitude simulation (T1): 11.6 kPa for 6+ hours. Simulates air transport at altitude. Tests pressure differential effect on cells.
Thermal test (T2): 72°C ±2°C for 6 hours, then -40°C ±2°C for 6 hours, repeated 10 times. Tests extreme temperature cycling.
Vibration (T3): Sine sweep 7-200 Hz, then 12 cycles in 3 perpendicular axes. Tests structural integrity under vibration.
Shock (T4): Half-sine 150 G / 6 ms (or 50 G / 11 ms for large cells). 3 shocks per axis, 6 axes total = 18 shocks. Tests impact survivability.
External short circuit (T5): <0.1 ohm external resistance. Tests thermal runaway prevention under short.
Impact (T6): 9.1 kg weight from 61 cm onto cell. Tests internal short circuit prevention. Only for cells (not batteries).
Overcharge (T7): 2x manufacturer recommended charge current for 24 hours. Tests overcharge protection. Only for rechargeable batteries.
Forced discharge (T8): 12V DC, 1x capacity for 12 hours. Tests deep discharge behavior. Only for rechargeable cells.
Test report: Must be issued by accredited lab (UN Manual lists labs). Test summary required on shipping documents.
UN 38.3 vs IEC 62133: UN 38.3 is transport safety. IEC 62133 is product safety. Both usually required for Li-ion products.
B2B recommendation: Require UN 38.3 test summary from battery supplier for every shipment. Verify lab accreditation.
PAS 63100:2025 Protective Case Safety Standard
PAS 63100:2025 (Publicly Available Specification) is the new BSI standard for protective cases used to transport lithium-ion batteries. Published 2025.
PAS 63100:2025: Publicly Available Specification published by BSI (British Standards Institution) in 2025. Covers protective packaging for lithium-ion cells / batteries during transport.
Scope: Outer packaging (cases, boxes, crates, drums) used to contain Li-ion cells / batteries during road, rail, sea, air transport. Applies to manufacturer + distributor + logistics provider.
Construction requirements: Case must contain any thermal runaway event for minimum 30 minutes without propagation to outer packaging. Tested via cell-level thermal abuse + observation.
Thermal runaway containment: Test 1 cell within case at 100% SOC, induce thermal runaway (nail penetration or heater). Case must not rupture, vent flame externally, or propagate to additional cells for 30 min.
Vibration: Case must pass UN 38.3 T3 vibration while loaded with batteries. No lid release, no cell shift >2 mm.
Shock: Case must pass UN 38.3 T4 shock while loaded with batteries. No rupture, no cell ejection.
Pressure equalization: If case is sealed, pressure relief valve required to prevent pressure buildup from thermal runaway gas.
Marking: Case must be marked "PAS 63100:2025 compliant" or "Lithium battery transport case - PAS 63100:2025" + date + manufacturer code.
Documentation: Manufacturer must issue PAS 63100:2025 Declaration of Conformity (DoC) with each shipment.
Relation to UN 38.3: UN 38.3 tests cells / batteries. PAS 63100:2025 tests the OUTER protective case. Both required for Li-ion transport in case.
B2B recommendation: For B2B orders of Li-ion transport cases, verify case is PAS 63100:2025 compliant. DoC must be issued by case manufacturer.
Recycled Content Requirements 2027-2031
EU Battery Regulation 2023/1542 mandates minimum recycled content for lithium-ion batteries, phased from 2027 onward.
Recycled content thresholds (Li-ion, by 2031): 16% cobalt from recycling, 6% lithium from recycling, 6% nickel from recycling, 90% lead from recycling (already mature).
2027 thresholds (50% of 2031): 8% cobalt, 3% lithium, 3% nickel.
Calculation: Recycled mass / total mass of specific metal. Verified via chain of custody documentation from battery manufacturer.
Reporting: Battery manufacturer must publish recycled content percentage per model year. Available in technical documentation.
Documentation required: Recycling stream identification, mass balance calculation, audit trail, conformity assessment.
B2B relevance: Protective case manufacturer typically does not need to verify battery recycled content — but B2B buyer of batteries + case must request recycled content documentation from battery manufacturer.
Non-compliance: Battery cannot carry CE mark without recycled content declaration. Customs may refuse entry. Distributor may be liable.
Transition: From 2027, Li-ion battery products in EU market MUST declare recycled content. Pre-2027 batteries in stock may continue until sold.
Cost impact: Recycled content adds 2-5% to Li-ion battery cost in 2027, rising to 5-10% by 2031. Expect slight price increases for EU-bound products.
B2B recommendation: Request recycled content percentage from Li-ion battery supplier. Confirm DoC includes recycled content compliance.
Carbon Footprint Declaration 2026
From 2026, EU Battery Regulation requires carbon footprint declaration for LMT (e-bike / scooter / light EV) and portable Li-ion batteries.
Carbon footprint: Total CO2-equivalent emissions per kWh battery capacity over full lifecycle (raw material extraction + manufacturing + use + end-of-life).
PEF (Product Environmental Footprint) method: EU recommended method for battery carbon footprint. Aligns with ISO 14067.
Scope (2026): LMT batteries first, portable Li-ion batteries second (2027), EV batteries third (2025 reporting already started).
Calculation: Manufacturer must use PEF methodology + verified emission factors. Verified by accredited third party.
Performance classes (planned): A-G class system based on carbon footprint per kWh. Class A is best, G is worst.
Threshold values (planned 2026-2027): Maximum allowed carbon footprint per kWh. Above threshold = cannot be sold in EU.
Documentation: Carbon footprint declaration must accompany battery + be published on EU product database.
B2B relevance: EU-bound B2B orders of Li-ion batteries must include carbon footprint DoC. From 2027, threshold values enforced.
Cost impact: PEF study adds EUR 5,000-15,000 per battery model. Typically amortized over production volume.
B2B recommendation: Verify Li-ion battery supplier has carbon footprint DoC ready for 2026 EU-bound orders.
