Our company , Huizhou Mingda , has comprehensively carried out activities to respond to the EU RoHS directive. All material of our full-line products are compliant with RoHS.
Don’t hesitate to contact us for RoHS report for inductor , air coil or transformer.

We respond to various environmental regulations in the European Union in a timely manner by conducting organizational activities centered on autonomous management and restriction of the use of chemical substances.

Therefore, we can provide you with products that comply with the EU RoHS Directive on Restricting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment.

The Directive on the Restriction of the Use of Certain Hazardous Substances in Electronic and Electrical Equipment (2011/65/EU) issued by the European Union and its amendments.

The directive prohibits the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) in electronic and electrical equipment in excess of the maximum allowable limits, except for purposes that comply with exemption clauses. Therefore, the so-called ‘compliance with the EU RoHS Directive’ refers to not violating the prohibitions stipulated in the aforementioned directives.

Our company developed the first version of the “Management Table for Restricting the Use of Environmental Load Chemicals” in 2006, which has been committed to reducing and eliminating harmful chemical substances since a very early stage.

In the first version of the ‘Management Table’, we have already started to classify the six substances specified in the EU RoHS Directive as environmental load chemicals, and have designated them as restricted and contained substances, carrying out activities that do not contain prohibited chemicals.

1.Comply with the old directive (2002/95/EC)
1. Mercury, cadmium, and specific brominated flame retardants were completely abolished by 1990, and hexavalent chromium used for surface treatment, lead used for connecting terminals, and welding were also completely abolished by the end of 2004, and their use was also prohibited in subsequent new regulations.

2.Compliance with the new directive (2011/65/EU)
Since January 2013, we have redesigned and developed lead-free materials for some of our company’s products that do not comply with the new directive. By the end of June 2013, we completed the preparation of alternative products that can comply with the EU RoHS directive.

With the assistance of customers and suppliers, we have been able to supply products that fully comply with the EU RoHS directive since January 2006. After the implementation of the new directive in January 2013, this system has also been maintained (excluding some products provided due to special customer requirements).

Regarding the use of “lead” in ceramic dielectric material capacitors with rated voltages less than 125VAC or 250VDC and the use of this component. Assurance system for products that comply with EU RoHS directives.

In response to the EU RoHS directive, we have summarized the following management points. In various stages of activities, we have taken corresponding measures to address these key points and are committed to building a comprehensive response system.

1. Development，Prepare products that comply with RoHS directives and substitute products that do not contain prohibited chemicals.

2.Purchases，Confirm and ensure that the purchased components and materials comply with RoHS directives, and do not purchase components and materials containing prohibited chemicals.

3.Production,Prevent the inflow and mixing of controlled substances during the production process, prevent products containing prohibited chemicals from entering or mixing into the production process.

4. Identify, establish methods for identifying products that comply with RoHS directives, identify whether they contain prohibited chemicals

5.Sales，Order management for products that do not comply with RoHS directives, and implement management for ordering business for products that do not comply with RoHS directives

6. Inventory, scrap inventory of products that do not comply with RoHS directives, no inventory of products containing prohibited chemicals.

Example 1: Supplier’s Supply Product Assurance System
1)Implementation monitoring of the EU RoHS directive management system for suppliers
2)By conducting a greenness survey of materials, confirm whether each component and material contains (or does not contain) specific substances
3)Using the EDP system to restrict the procurement of uncensored components and materials
4)Exchange of Guarantee Letter for Substances Not Controlled by EU RoHS Directive

Example 2: Measures to prevent the mixing of prohibited chemicals in production processes
1)Apply analytical methods to inspect products flowing into the production line
2)Separate production processes for products that comply with and do not comply with EU RoHS directives
3)Separate storage of components and materials that comply with and do not comply with the EU RoHS directive, and label them separately

Example 3: Identification Method for Imported Products
1)Develop clearly distinguishable work instructions for each production process
2)Mark identification marks on the outer packaging and individual packaging labels of 3)all supplied products (which can also be directly identified during the logistics stage)
4)Confirmation method for products that comply with the EU RoHS directive
5)Confirmation method of physical objects
6)This can be confirmed by the identification marks marked on the outer packaging of the physical object or on the labels of individual packages.
