12027 The Year of ChinaRoHSCompliance situation and challenges

1.1 ChinaRoHSMandatory national standards officially implemented

2025 year8 In September, China officially released the mandatory national standard for the control of hazardous substances in electrical and electronic products, "Requirements for the Restriction of Hazardous Substances in Electrical and Electronic Products"(GB 26572-2025)Will be2027 year8 moon1 Officially implemented on a daily basis. The introduction of this standard marks a milestone for ChinaRoHSControl has entered a new stage, imposing stricter compliance requirements on the electronic manufacturing industry. Unlike previous recommended standards, this mandatory standard will directly affect the production, sales, and import processes of products, and enterprises must attach great importance to it.

1.2 Main control content and scope of application

This standard specifies the control of potential contaminants that may be present in electrical and electronic products 10 Chemicals that are toxic and harmful to human health and the environment, including lead, mercury, cadmium, hexavalent chromium, etc4 Heavy metal elements and polybrominated biphenyls, polybrominated diphenyl ethers4 Substances such as phthalates6 Persistent organic pollutants. The specific controlled substances and limit values are as follows:

The scope of application of this standard covers almost all'Electric products', including:

•Consumer electronics: smartphones, tablets, laptops, televisions, digital cameras, game consoles, etc

•Household appliances: refrigerators, air conditioners, washing machines, electric water heaters, etc

•Office equipment: printers, copiers, fax machines, etc

•Communication equipment: mobile communication handheld devices, standalone telephones, etc

1.3 Composition and Challenges of Compliance Costs

For electronic manufacturing enterprises,RoHSCompliance involves multiple costs, mainly including:

1. Investment in testing equipmentHigh precision instruments such asICP-MSTheGC-MSTheXRFWaiting for equipment procurement and maintenance costs

2. Sample pre-treatment cost: Costs of consumables such as chemical reagents and solvents, as well as operating expenses for laboratory personnel

3. labor costProfessional personnel's testing, review, and report writing

4. Certification and reporting feesIssuance of qualified inspection reports, certification certificates, and subsequent consulting services

5. Compliance management costsSupply chain management, supplier auditing, document management, etc

6. Cost of handling false positives and non-conforming productsHidden costs such as rework, returns, and loss of market reputation caused by unqualified test results

According to statistics, for small and medium-sized electronic manufacturing enterprises,RoHSThe compliance cost can reach up to the total cost of the enterprise5.2%With2027 The implementation of mandatory standards in the year poses greater compliance pressure and cost challenges for enterprises.

1.4 ChinaRoHSCore changes of new regulations

2025 year8 moon1 Daily ReleaseGB 26572-2025As a ChineseRoHSMandatory national standards have brought about significant changes:

•Expansion of controlled substances: New addition 4 Phthalate esters（DEHPTheBBPTheDBPTheDIBP）The total number of restricted substances has increased from the original6 Increase in species10 Seed, in line with EU standards

•Mandatory standardization: AbolitionGB/T 26125Mandatory adoptionGB/T 39560The series of standards has come to an end'Different results from different laboratories'The chaos

•Increased testing requirementsExplicitly require enterprises to establish a green supply chain management system and require suppliers to provideSDSReport, disabledTDCPP/TCEPFlame retardants, etc

•Dynamic adjustment of exemption clauses：2025 The EU has made intensive revisions to the exemption clauses for mercury, cadmium, and lead, such as the exemption for cadmium quantum dots2027 Year end expiration, mercury exemption for high-pressure sodium lamps extended to2027 year2 moon24 Daily waiting

These changes have put forward higher requirements for enterprises, especially for those that need to meet both the Chinese and EU markets, the complexity and cost of compliance management have significantly increased.

1.5 Update of detection methods and cost impact

GB/T 39560Series standards2024 year3 moon1 The standard has been officially implemented and includes multiple parts:

•GB/T 39560.301：XX-ray fluorescence spectroscopy（XRF）Screening for lead, mercury, cadmium, total chromium, and total bromine

•GB/T 39560.6Gas chromatography-Mass spectrometry method（GC-MS）Determination of polybrominated biphenyls and polybrominated diphenyl ethers in polymers

•GB/T 39560.8Gas chromatography-Mass spectrometry method（GC-MS）Equipped with thermal cracking/Thermal desorption gas chromatography-Mass spectrometry method（Py/TD-GC-MS）Determination of Phthalates in Polymers

According to industry analysis, the increase in testing costs after the implementation of the new regulations is mainly reflected in three aspects:

•Increase in testing itemsThe newly added phthalate detection requires additional sample preparation and analysis time

•Method upgrade requirementsEnterprises need to complete laboratory method updates within two years, which may involve equipment upgrades and personnel training

•Supplier audit costNeed to impose stricter environmental requirements on upstream component and material suppliers and obtain relevant certification documents

Taking a certain electronic manufacturing enterprise as an example, its annual testing costs have increased from the original 30 Ten thousand yuan increased to about42 Ten thousand yuan, with an increase of40%This directly reflects the impact of the new regulations on the operating costs of enterprises.
