US CPSC 16 CFR 1262 Anti-Detachment Magnet Engineering & RoHS/REACH
Every magnetic slider, haptic coin, and spinner ring across the FidgetSupply.com manufacturing network is engineered with mechanical and chemical retention so magnets never detach under drop or torque abuse.
US CPSC 16 CFR Part 1262 & EU RoHS/REACH Compliance Summary
Under US CPSC 16 CFR Part 1262, entertainment and stress-relief products containing neodymium magnets must prevent any small magnet with a Flux Index >= 50 kG²mm² from liberating during drop, impact, torque, and tension abuse testing. FidgetSupply enforces a 3-Layer Anti-Detachment Protocol across all 140 molds: (1) Captive blind-hole counterbores covered by screw-locked stainless/PTFE plates, (2) Automated two-part modified epoxy dispensing (>22 MPa shear strength), and (3) Anaerobic threadlocker on all M2/M2.5 fasteners.
3-Layer Magnet Retention & Structural Lock Matrix
| Engineering Layer | Factory Process Specification | QC Verification Test | Applicable Product Lines |
|---|---|---|---|
| 1. Captive Mechanical Plate Enclosure | Magnets are seated in internal blind pockets sealed beneath a PTFE wear plate or CNC stainless top plate fastened by 2–8 M2/M2.5 machine screws or Chicago sex-bolts. | Zero physical exit path even if adhesive bond is thermally cycled | FS-001, FS-016, FS-035, FS-094, FS-114, FS-125, FS-128, FS-150 |
| 2. Two-Part Structural Acrylic/Epoxy Bonding | Automated pneumatic dispensing of industrial structural adhesive (shear strength >22 MPa, operating range -40°C to +120°C) into precision-chamfered magnet wells. | 48-hour thermal shock (-20°C to +80°C) + 10-drop 1.5m steel plate impact test | All Magnetic Sliders, Coins, Gourds & Rings |
| 3. Anaerobic Thread-Locked Fasteners | All M2, M2.5, M3 hex socket screws and bearing retention caps are torqued with medium/high-strength anaerobic threadlocker. | ASTM F963 / 16 CFR 1500.53 Torque (0.45 Nm) & Tension (70 N) clamp test | Multi-Action Mechanical EDC & Multi-Axis Gyros |
| 4. RoHS 3 & REACH Metallurgy Control | Virgin Zamak #3 zinc alloy, 6063-T6 aluminum, 304/316 stainless steel, C36000 lead-free brass, and nickel-release compliant PVD/electroplating. | XRF spectrometer screening on every incoming metal ingot batch | 100% of Catalog (FS-001 to FS-150) |

US CPSC 16 CFR Part 1262 (Safety Standard for Magnets) requires that entertainment and stress-relief products containing magnets either not consist of loose small magnets that fit within the CPSC small-parts cylinder (Ø31.7mm × 57.1mm) with a Flux Index >= 50 kG²mm², or ensure embedded magnets never liberate during drop, torque, and tension abuse testing.
Every magnetic model across our 140 molds utilizes a 3-layer retention architecture: (1) precision CNC/die-cast blind pockets covered by screw-locked stainless or PTFE plates, (2) automated pneumatic dispensing of two-part modified structural epoxy (>22 MPa shear strength), and (3) medium-strength anaerobic threadlocker on all M2/M2.5 fasteners.
Under our standard pre-shipment quality protocol, random production units undergo a 48-hour thermal shock cycle (-20°C to +80°C) followed by 10 consecutive drops from 1.5 meters onto a steel-backed concrete plate across 6 orientations, plus 0.45 Nm torque and 70 N tension testing with zero magnet liberation.
All metal EDC sliders, haptic coins, spinners, and mechanical rings should be marketed and labeled as Adult Everyday Carry (EDC) Desk Toys graded for Ages 14+ (or 15+). They are not children’s toys (under 14) and every custom packaging order includes mandatory 14+ & magnet safety warning labels.
Yes. For confirmed wholesale buyers, we supply factory General Certificates of Conformity (GCC), 16 CFR Part 1262 magnet retention abuse test reports, XRF RoHS 3 / REACH heavy-metal compliance sheets, and compliant packaging artwork proofs required by Amazon Seller Central.
Yes. We use virgin Zamak #3 zinc alloy, SUS304/316 stainless steel, 6063-T6 aluminum, and RoHS-compliant lead-free brass. All electroplated and PVD finishes pass EU Directive 2015/863 (RoHS 3) for Lead, Cadmium, Mercury, and Hexavalent Chromium, as well as EN 1811 nickel-release limits.
International air transport (IATA Packing Instruction 953) requires that magnetic packages produce a stray magnetic field strength below 0.00525 gauss at 4.6 meters (15 feet). Our Fuzhou Export Logistics Hub lines master cartons with high-permeability iron shielding sheets and provides DGM/IATA magnetic inspection certificates.
Yes! We manufacture over 30 pure mechanical and rotational models that contain zero magnets—including FS-005 (304 Stainless Knuckle Roller), FS-009 (Knurled Twist Top), FS-043 & FS-066 (Multi-Axis Gimbal Gyros), FS-061 & FS-079 (Chain Sprocket Spinners), FS-063 (316 Stainless Goose Spinner), FS-067 (Bolt-Action Slider), and FS-085 / FS-092 (Mechanical Spring Ratchets).
Yes. All stainless steel, anodized aluminum, PEI Ultem, zirconium, and PVD/electroplated zinc alloy models meet California Prop 65 phthalate and heavy-metal thresholds, and we can print Prop 65 informational labels on outer packaging upon request.
Absolutely. We welcome SGS, TUV, Intertek, Bureau Veritas, or QIMA inspectors at our Fuzhou Industrial Zone Export Logistics Hub prior to balance payment and shipment dispatch.
