Direct answer
A magnetic STEM toy specification should identify every magnet, its location, purpose, containment method, compatible modules and approved sample revision. Importers and educational toy brands should then request retention and use-and-abuse evidence for the finished product, not a generic magnet certificate. Packaging, age grading, warnings, instructions and target-market documents must match the ordered configuration and any optional magnetic accessories.
Name the procurement decision
This guide is for importers, brand owners, compliance teams and education suppliers deciding whether a magnetic product configuration is sufficiently defined for quotation, sample approval and market review. The decision is: Can every magnetic component and compatible module be traced from the approved BOM and sample to the instructions, risk assessment, test evidence and final package?
YSGO's STEM Logic Thinking Training Blocks provide a relevant module-combination direction. Product-line positioning is not a compliance file, and buyers must not assume every model includes magnets.
Build a magnetic-component specification
| Specification field | What to record | Why it matters |
|---|---|---|
| Magnet identity | Part code, dimensions, grade or supplier specification where applicable | Prevents substitution and links evidence to the ordered component |
| Quantity and location | Count per finished item and exact containment point | Supports inventory, risk review and inspection |
| Retention method | Enclosure, overmolding, fastener, adhesive or other verified construction | Defines what must remain unchanged after approval |
| Compatible modules | Exact model, connector and revision matrix | Prevents unsupported cross-model combinations |
| Accessibility checks | Initial condition and condition after applicable use-and-abuse testing | Addresses foreseeable loosening or damage |
| Package status | Standard included, optional, replacement or not supplied | Prevents marketing and BOM mismatch |
Apply the rule to current YSGO facts
The YSGO 2026 catalog entry for YS2965A shows 15 block modules, a 36-page content item and an assembly tutorial. The catalog depicts a magnet and a USB charging cable and says additional magnetic pieces can be purchased. However, the quantity of magnetic pieces supplied as standard has not been confirmed. The product page or quotation must not state a standard magnetic count until the BOM or physical package confirms it.
For YS2965C, catalog evidence records a seven-piece remote-control and FM radio/speaker set. The catalog states that the magnet play direction is optional and that the magnet is not supplied with the standard set. A buyer adding the optional component must treat the resulting configuration as a defined project variation and review its sample, package, instructions and evidence accordingly.
Request an evidence index, not a certificate folder
- Product model, variant and revision match the quotation and test sample.
- BOM identifies every magnet and magnetic accessory by part code and quantity.
- Compatibility is documented for every approved module combination.
- Applicable tension, torque, drop, impact or other use-and-abuse checks are identified for the target age and market.
- Results show whether a magnet becomes loose or accessible after the applicable sequence.
- Package, manual, warnings, age grading and marketing show the same configuration.
- Optional magnets are clearly separated from standard included contents.
The CPSC toy-safety guidance identifies magnet requirements in ASTM F963 section 4.38. The CPSC magnet FAQ also explains that toys covered by ASTM F963 are exempt from the separate magnet rule; the two routes should not be applied interchangeably. Those sources do not replace legal or laboratory review for a finished item.
Control the main magnetic failure risks
Image-to-BOM substitution: A rendered or catalog image may show an optional accessory. Only the controlled order documents should define included content.
Retention drift: A change to housing, adhesive, fastener, molding, magnet or assembly process can affect the approved construction and evidence.
Family-report overreach: A report for one model, count or enclosure should not be extended automatically to another variant.
Applicable requirements and testing depend on the final product, intended age, intended use and target market. Electrical or light-up functions may also require an applicable IEC 62115 assessment and other market-specific review. YSGO can discuss module, instruction, packaging and branding configurations subject to feasibility, sample and compliance review; this article does not promise a certificate, test result, MOQ or timing.
Get a Model Recommendation: Share the target market, intended age, required magnetic function, standard and optional modules, buyer channel and quantity through the YSGO inquiry page so YSGO can identify a sample configuration and the evidence that must be confirmed.
Frequently Asked Questions
Does a supplier magnet certificate cover the finished toy?
Not by itself. Buyers need evidence tied to the finished construction, exact magnets, intended age, foreseeable use, test sequence and target market.
Can a pictured magnet be listed as standard content?
Only when the approved BOM, physical sample and package confirm that it is supplied. Current YS2965A evidence does not confirm the standard magnetic quantity.
Can optional magnetic pieces use the standard product's evidence?
Do not assume so. Adding an accessory can change the configuration, accessible components, instructions, package and testing scope. Review the combined version.
Does magnetic compatibility prove module compatibility?
No. Physical attraction or fit does not prove correct electrical behavior, structural stability, activity support or safety. Use a controlled compatibility matrix.
