Regulations and Standards for Cell Phone Cases

The export of cell phone cases to European and American markets presents broad opportunities, but products must pass strict complianCE certifications such as RoHS and Annex XVII of REACH. Failure to comply may resULt in product rejection, recall, fines, and other consequences.

Types of Cell Phone Cases

①　Silicone Phone Cases: Soft and skin-friendly, with excellent anti-slip, shockproof, and waterproof performance, as well as an affordable price point. However, they tend to attract dust easily, have poor air permeability, and may affect phone heat dissipation with long-term use.

②　TPU Phone Cases: Boast good elasticity, comfortable hand feel, shatter resistance, and antibacterial properties, while being lightweight and easy to clean. Yet they are prone to deformation and yellowing over time.

③　Metal Phone Cases: Feature a premium texture, outstanding heat dissipation, and strong impact resistance. But they may interfere with mobile phone signals and have a relatively heavy weight.

④　Leather Phone Cases: Offer excellent hand feel and texture, along with durability and stylish appearance. Nevertheless, they come with a higher price tag, lack waterproof capability, and can be inconvenient to carry when oversized.

⑤　Clear Cases: Made of transparent silicone material with a moderate hardness.

⑥　Mesh Cases: Provide excellent air permeability and fast heat dissipation with a minimalist design. But they have poor dustproof and waterproof performance, and small holes are likely to accumulate dirt.

⑦　Plush Phone Cases: Have a soft, anti-slip touch and cute appearance, but are easy to trap dirt and grime.

⑧　Magnetic Phone Cases: Such as Apple’s official MagSafe magnetic cases, they can be attached instantly and support wireless charging.

Testing Items for Cell Phone Cases

ROHS certification

The RoHS Directive mainly restricts hazardous substances in electrical and electronic products. For all types of cell phone cases, 10 substances are subject to mandatory testing, including:

①　Lead (Pb)

②　Mercury (Hg)

③　Cadmium (Cd)

④　Hexavalent chromium (Cr VI)

⑤　Polybrominated biphenyls (PBBs)

⑥　Polybrominated diphenyl ethers (PBDEs)

⑦　BIS(2-ethylhexyl) phthalate (DEHP)

⑧　Benzyl butyl phthalate (BBP)

⑨　Dibutyl phthalate (DBP)

⑩　Diisobutyl phthalate (DIBP)

⑪　Metal phone cases: Need to test the content of heavy metals such as lead and cadmium to prevent excessive levels from endangering human health and the environment.

⑫　Silicone, TPU, and other polymer-based phone cases: Must be tested for excessive hexavalent chromium and flame retardants like PBBs and PBDEs.

Testing Items under Annex XVII of REACH

In addition to the substances listed in RoHS, the following items are also coveRED:

①　Phthalates

②　Polycyclic Aromatic Hydrocarbons (PAHs) (additional testing is recommended for dark-colored rubber/silicone materials)

Testing Equipment for Cell Phone Cases

①　X-Ray Fluorescence Spectrometer (XRF): Used for detecting the presence of heavy metals such as lead (Pb), cadmium (Cd), and mercury (Hg). This device can quickly analyze the elemental composition of materials and is a commonly used tool for RoHS Compliance testing.

②　Gas Chromatography-Mass Spectrometry (GC-MS): Primarily used for detecting organic compounds, such as phthalates and other harmful cheMICals. These substances may be restricted or prohibited under Annex XVII of REACH.

③　Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES): Capable of accurately measuring the metal content in samples, including but not limited to lead, cadmium, and nickel—all of which are strictly regulated under Annex XVII of REACH.
