International Timeline Comparison for Battery Rules

Battery rule timelines differ by jurisdiction, and there is no single global deadline for battery passports, because the EU has a fixed passport date, the UK has no matching passport duty stated, and US states have stewardship and fee dates that vary by state and by law. A timeline that states a single global date for battery passports misstates all three systems, and a business that plans to a single date will be early in one jurisdiction, late in another and unprepared in a third. The comparison in this guide therefore keeps the timelines apart, with a jurisdiction label and a status label on every date, so that a fixed date is never confused with an expected date, and an expected date is never confused with a fixed date.

The scope is a timeline comparison at system level, as checked on 28 October 2026, with the EU dates stated from the Regulation summaries, the UK position stated as no passport duty, and the California dates stated as summarised in the sources consulted.

What is the EU timeline?

The EU timeline starts with the Regulation entering into force in August 2023 and applying since 18 February 2024, with individual provisions phased in on their own dates, and with the battery passport duty in Article 77 applying from 18 February 2027 for electric vehicle batteries, light means of transport batteries and industrial batteries over 2 kWh. Other EU dates, including labelling, carbon footprint, recycled content and due diligence dates, phase in on separate timetables, some dependent on delegated or implementing acts, and the due diligence start was delayed by a later amendment. The EU timeline should therefore be read as a fixed passport date inside a phased framework, with the phased dates checked against the current consolidated text rather than treated as fixed.

What is the UK timeline?

The UK timeline, as far as the sources consulted state, has no battery passport date, because the UK framework of the 2008 and 2009 regulations contains no matching passport duty for Great Britain. The UK timeline is therefore a timeline of producer responsibility, registration and collection duties under the existing regulations, with no passport milestone to plan to. A UK timeline that copies the EU passport date into the UK column misstates the UK position, and a business that plans a UK passport for 18 February 2027 on the strength of the EU date will have prepared for a duty that the UK sources do not state. The UK column should be left without a passport date, with a note that the position is stated as checked on 28 October 2026 and should be rechecked if UK law changes.

What is the US timeline?

The US timeline is a set of state timelines, with California as the worked example, where AB 2440 stewardship programmes are described as beginning no later than 1 April 2027, SB 1215 point of sale fees are described as applying from 1 January 2026, and SB 1215 reporting is described as applying from July 2027, all as summaries record. Other states have their own start dates, and rulemaking for new laws may still be in progress, so the US timeline cannot be stated as a single line. A US timeline should be kept as a state register, with each state, each law and each start date labelled, and with a recheck date for states where rulemaking is incomplete. The California dates in this guide are labelled as summarised dates, not as verified rulemaking outcomes.

What does a timeline comparison table look like?

A timeline comparison table keeps fixed, phased and summarised dates apart, with a status label on every date. The table below states the positions in general terms.

How should a business plan across timelines?

A business should plan across timelines by working to the earliest fixed date that applies to its placings, while keeping phased and summarised dates as planning assumptions with recheck dates, rather than as fixed deadlines. The EU passport date is the earliest fixed date for EU placings, and preparation for that date should start with scope, category and data collection, as the implementation cluster describes. The US state dates should be planned state by state, with the state register updated as rulemaking progresses. A single project plan with a single deadline will fail to capture the different status of the dates, and the plan should therefore be kept as a dated register, not as a single timeline graphic.

What is uncertain in international timelines?

Uncertainty in international timelines arises from phased EU provisions that depend on further acts, from UK law that may change, and from US state rulemaking that is still in progress. Each uncertainty should be recorded with the jurisdiction, the provision, the uncertain point and the recheck date, rather than being resolved by treating an expected date as fixed. A timeline register that records uncertainty is more useful than a timeline that states every date with equal confidence, because a later reader can see which dates can be relied on for a placing decision and which dates are planning assumptions only. The register should be rechecked at the recheck dates, and the recheck should be recorded.

What limits apply to timeline comparisons?

The limits are that timelines change, and this comparison states the position as checked on 28 October 2026. This guide gives general educational information only and is not individual legal advice. A business with a specific placing should check the current text for that jurisdiction as checked on 28 October 2026 before acting.
