Magnetic cubes, fidget balls and stick figures: what US magnet rules require, and three CPSC actions

In the space of a week, the US Consumer Product Safety Commission (CPSC) acted on three magnetic products sold online. On October 29, 2026, it issued product safety warnings about magnetic sensory fidget balls sold on SHEIN.com and magnetic robot stick figures sold on Amazon.com. On November 5, it announced a recall of Magnetopia magnetic building cubes and blocks sold through the brand's own website. The three products differ, but the agency describes the same danger in all three notices: small, strong magnets that a child could swallow.

The three products

The Magnetopia cubes come in sets of 60, 100, 150 and 200 and snap together into 3D scenes, in themed designs such as Darkgrass, Farmday and Seafight. The recall lists 15 style and model combinations, by our count, with model numbers MAT-030 to MAT-040 and T009, T025, T076 and T078, printed on the back of the packaging. The fidget balls are a set of four silicone balls about 1.18 inches across, each in a different shade of green and texture, kept in a round black case; the CPSC says they also come in sets of eight. The stick figures are robot-shaped, sold in packs of five or 10 in five colors, with a small magnet in each hand and foot. The code X004N3MGCB is printed on the back of their packaging.

The fidget ball warning's title refers to the mandatory standard for magnets, while its text says the balls violate the mandatory safety standard for toys. The Magnetopia recall does not say the cubes break a standard; it describes magnets that can come loose.

Why the CPSC treats swallowed magnets as serious

Each notice explains the risk in the same terms. According to the CPSC, swallowed high-powered magnets can be drawn to one another, or to other metal objects, and lodge in the digestive system; the agency lists perforated, twisted or blocked intestines, blood poisoning and death among the possible results.

The agency set out its injury evidence when it published its magnet rule in September 2022. Using its national sample of hospital emergency departments, it estimated 26,600 emergency room visits for swallowed magnets from 2010 through 2021, 2,800 of them in 2021. About 5,000 of those patients, or 20%, were hospitalized or transferred to another hospital. CPSC staff were also aware of seven deaths from swallowed hazardous magnets between November 24, 2005, and January 5, 2021, two of them outside the US.

The CPSC also wrote that ingestions fell significantly in the years when an earlier rule on magnet sets, issued in 2014, was announced and in force. That rule took effect in April 2015 and was vacated by the US Court of Appeals for the Tenth Circuit in November 2016. The agency's estimates for all magnet ingestions averaged about 1,300 a year in 2014 through 2016, against about 2,300 a year in 2010 through 2013 and 2,400 a year in 2017 through 2021.

Two rules, depending on what the product is

Which US rule applies depends on whether a magnet product counts as a toy. The CPSC's toy standard, which incorporates the ASTM F963 toy safety standard, covers objects designed, made or marketed as playthings for children under 14. Magnet products that are not toys come under the Safety Standard for Magnets, 16 CFR part 1262, if they are designed, marketed or intended for entertainment, jewelry (children's jewelry included), mental stimulation or stress relief. That rule applies to products made after October 21, 2022. Products sold only to school educators, researchers, professionals or commercial and industrial users are excluded, and toys covered by the toy standard are exempt from it.

Under the magnet rule, every loose or separable magnet that fits entirely within the CPSC's small parts cylinder must have a flux index, a measure of its strength, below 50 kG² mm². Testing follows the method set out in sections 8.25.1 to 8.25.3 of ASTM F963, the toy standard itself. The CPSC's FAQ adds that the rule covers single magnets as well as sets, and that a component which holds a magnet but still fits in the cylinder is also in scope. Makers or importers must certify compliance, with a Children's Product Certificate for children's products or a General Certificate of Compliance for general-use products.

In a November 2022 letter to retailers and sellers, the CPSC's Office of Compliance and Field Operations said the rule makes it unlawful to sell non-compliant magnet products made after October 21, 2022, urged them to review their listings, and warned that failing to comply could lead to enforcement action and civil penalties.

What the CPSC tells owners

For the Magnetopia cubes, the recall tells owners to stop using them at once and contact Magnetopia, which provides a prepaid label to send them back for a full refund. For the fidget balls and the stick figures, there is no recall: the CPSC urges owners to stop using them immediately, dispose of them and not sell or give them away. Incidents can be reported to the agency at SaferProducts.gov.

What the records do not show

None of the three notices reports an incident, and the Magnetopia recall does not say how the cubes were found to break or open. The fidget ball warning says the balls may also have been sold by other sellers and on other websites, but names none. Each notice covers only the products, models and sellers it lists; magnetic toys of a similar design from other brands are not part of them. The injury estimates come from the CPSC's 2022 rulemaking and stop at 2021; the pages we read give no later national figures.

How this guide was put together: we read the three CPSC notices, the agency's magnet business guidance and FAQ, its 2022 letter to retailers, and the final magnet rule as published in the Federal Register. We have not tested any of these products.
