For mobile phone chargers to enter the EU market, they must obtain CE certification. This certification is a mandatory mark indicating that the product complies with EU regulatory requirements, covering two core areas: electrical safety (LVD) and electromagnetic compatibility (EMC), to ensure the product does not cause harm to users or the environment during normal use.

Production equipment refers to the means of labor or utensils that are operated by production workers during the production process and are necessary for directly changing the properties, performance, form of raw materials or enhancing the appearance value. Examples include blast furnaces, machine tools, reactors, printing and dyeing machines, etc.

Medical consumables are expendable medical devices used in medical activities such as diagnosis, treatment, health care and rehabilitation, including disposable or reusable types.

The cost of CE certification mainly depends on the customer's product, its operating environment, and the identified standards that determine the price. Different products have different parameters, so the directives involved also vary.
