On June 24, 2026 the Consumer Product Safety Commission published a proposed mandatory safety standard for lithium‑ion batteries used in micromobility products. Requests for oral presentation were due July 24. Written comments closed on August 24 — three days ago. The rule is now in the Commission's hands, and the final text is unknown.
That gap is the most useful window an importer is going to get, and most of them will spend it waiting.
What the rule actually reaches
The scope is wider than the headline suggests. It covers electric bicycles, electric scooters, and other light electric vehicles — but it also reaches electrical system components, replacement battery packs sold separately, and conversion kits. If you sell a spare pack or a kit that turns an analog bicycle into an electric one, you are inside this rule, not adjacent to it.
The proposed requirements build on and modify the existing UL voluntary standards rather than replacing them wholesale:
- Tamper‑resistant battery enclosures
- Post‑discharge testing to address overheating after a pack is run down
- Reverse‑polarity testing
- Protection against incompatible chargers — the failure mode behind a meaningful share of the fires that drove this rulemaking
- Expanded and revised warning label requirements
- Third‑party testing and certification for products intended for children
Once the final rule publishes, manufacturers get 180 days to comply. An anti‑stockpiling provision closes the obvious back door of building ahead and selling through the transition.
Why 180 days is shorter than it sounds
Having sat on the OEM side of supplier change control, I would tell you the calendar is not the constraint. The constraint is that most brands in this category do not know, in any documented way, what is inside the pack they are selling.
A compliance deadline is a documentation problem before it is an engineering problem. You cannot certify what you cannot describe.
The typical light‑electric‑vehicle brand in the United States is an importer, not a manufacturer. The pack came from a supplier who sourced cells from another supplier. The BMS firmware version that shipped in March may not be the one that shipped in September. The charger was qualified once, by someone who has since left. None of that is unusual and none of it is disqualifying — but all of it takes longer than 180 days to reconstruct after a deadline lands.
The work that actually fits in the window, in order:
- Establish the real configuration. Cell chemistry and supplier, pack architecture, BMS hardware and firmware revisions, enclosure and fastener design, charger part numbers, and which SKUs and model years each applies to.
- Find the change history. Every supplier substitution, firmware revision, and running change since launch, with dates. This is the piece nobody has and everybody needs.
- Test against the proposed requirements now, not the final ones. Post‑discharge and reverse‑polarity behavior are unlikely to disappear from the final rule. If a pack fails those today, that is a design cycle, not a paperwork cycle.
- Read your existing warnings against the proposal. Labeling is the cheapest thing on this list and the first thing a plaintiff's expert will hold up.
- Inventory the conversion kits and replacement packs. They are in scope and they are usually managed by whoever handles accessories, which means nobody.
The exposure that isn't on the compliance calendar
Compliance is forward‑looking. Litigation is not.
Every unit sold before this rule takes effect stays in service — in garages, in apartment hallways, on charge overnight. When one of them fails, the proposed rule becomes an exhibit. Not because it was binding at the time of sale, but because it establishes what was known, when it was known, and what the industry was told to do about it.
That is the mechanism in most failure‑to‑warn and design‑defect claims, and it does not require the rule to be final. A published NPR, the docket behind it, and the UL standards it builds on are all evidence of notice. The question in the case will not be whether a company met a deadline that had not arrived. It will be what a reasonable product organization did with the information available.
Which is a product management question, and it has a documented answer or it doesn't.
What to watch next
The Commission now reviews the comment record. This rulemaking already took an unusual route — the notice was pulled back through interagency review in 2025 before it ever reached the Federal Register — so the interval between comment close and a final rule is genuinely uncertain. It may be months. The scope may narrow.
None of that changes what a brand should be doing in the meantime, because every item on the list above is work you need anyway, rule or no rule. The deadline is just the thing that finally makes it urgent.
