Mobile phone cases exported to the EU require ROHS testing and certification to ensure that the products comply with the EU directive on restricting the use of certain hazardous substances in electronic and electrical equipment. ROHS certification mainly tests whether the mobile phone case contains lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), diphthalate Hazardous substances such as isobutyl ester (DIBP), 2-ethylhexyl phthalate (DEHP), dibutyl phthalate (DBP) and butylphenyl phthalate (BBP), and Make sure their levels are within specified limits.

The ROHS certification of mobile phone cases mainly detects whether the following ten harmful substances are contained in the mobile phone case materials and whether they exceed the prescribed limits:

1. Lead (Pb) - mainly found in solder, glass, PVC, stabilizers, etc., limit: 0.1% or 1000ppm.

2. Cadmium (Cd) - Mainly found in switches, switches, connectors, casings, PCBs, contacts, batteries, etc., limit value: 0.01% or 100ppm.

3. Mercury (Hg) - mainly found in thermostats, sensors, switches and relays, light bulbs, etc., limit: 0.1% or 1000ppm.

4. Hexavalent chromium (Cr6+) - mainly found in metal anti-corrosion coatings, limit: 0.1% or 1000ppm.

5. Polybrominated biphenyls (PBBs) - Mainly used as flame retardants in PCBs, connectors, plastic shells, etc. Limit value: 0.1% or 1000ppm.

6. Polybrominated diphenyl ethers (PBDEs) - Same as above, limit: 0.1% or 1000ppm.

7. Diisobutyl phthalate (DIBP) - used as a plasticizer for PVC, limit: 0.1% or 1000ppm.

8. Phthalate (2-ethylhexyl ester) (DEHP) - Mainly used as PVC plasticizer, limit: 0.1% or 1000ppm.

9. Dibutyl phthalate (DBP) - used in PVC parts in combination with other plasticizers, limit: 0.1% or 1000ppm.

10. Butyl benzyl phthalate (BBP) - plasticizer used in polyvinyl chloride, vinyl chloride copolymer, cellulose, natural and synthetic rubber, limit: 0.1% or 1000ppm.

These restrictions ensure the environmental protection and safety of mobile phone case materials to protect consumer health and the environment. If these harmful substances in the mobile phone case material exceed the limit, you need to find alternative materials or make rectifications to meet the requirements of ROHS certification.
