What changed on October 7, 2026: The battery rules now name the state and city laws that ban uncertified packs and the hazardous materials rules for shipping them. Recalled items and speed unlock devices join the always-prohibited list.
In plain words: Most parts are welcome. Batteries are the serious one: some places ban uncertified packs, and most e-bike packs ship as hazardous materials, so only list packs you can sell and ship legally. Recalled items, speed unlocks, stolen goods, counterfeits and anything illegal get removed and can end a shop. This summary is here to get you oriented. The full text below is the binding version.
Lithium batteries (restricted, read this before listing)
State the certification. Every battery listing must state the pack’s certification honestly (UL 2271, UL 2849, UL 2580 or Uncertified, as the listing form asks). Hiding or misstating it breaks this policy. Packs must be UN38.3 tested, and a pack listed without UN38.3 testing can’t go live.
Where the law requires certification. California, New York State and New York City ban the sale of e-bike batteries that aren’t certified by an accredited testing lab to a standard their laws accept, such as UL 2271 or UL 2849. UL 2580 is a standard for electric vehicle batteries and isn’t one those laws name. Don’t sell an uncertified pack to a buyer in those places. If one orders it, don’t ship: email support@ionxsupply.com and we cancel the order and refund the buyer.
Shipping. Packs must ship under the US Department of Transportation’s hazardous materials rules (PHMSA, 49 CFR). A pack over 100 watt-hours, which is most e-bike packs, is fully regulated hazardous material (UN3480, Class 9). USPS won’t take it. Ship it by ground with a carrier hazmat account (such as UPS or FedEx Ground), by someone with hazmat training, with the Class 9 label and the required paperwork. Never ship a standalone pack by air.
Never allowed: damaged, swollen, water-exposed or repacked-cell packs; packs under a recall; homemade packs without a battery management system (BMS).
Always prohibited
Stolen goods (we may ask for serial numbers and work with law enforcement); anything under a recall by its maker or the US Consumer Product Safety Commission; speed unlock devices, dongles, apps or firmware that let an e-bike go faster than its class allows, however they are described; anti-theft or lock bypass tools; odometer tampering devices; counterfeit or IP-infringing items; and items you don’t have the right to sell.
Honest grading
Condition must be graded honestly (New, Like new, Used or For parts). “For parts” listings must say what’s wrong. Cracked frames, water-damaged electronics and crash-history components must say so in the description and photos.
Enforcement
First offense: the listing is removed. Repeat or serious offenses: the shop is suspended. Stolen, recalled or dangerous goods: the shop is closed at once and payouts not yet sent are held.
