“Environmental certification” for hardware structural components encompasses a broad range of standards, which can be categorized into three types: mandatory compliance regarding restricted hazardous substances (RoHS/REACH), environmental management system certification (ISO 14001), and certifications related to green products and carbon (Green Product Certification, EPD, carbon footprint, etc.). The specific certification requested by the client determines the scope of work required;
this article breaks down these three categories.
I.
Substance Restriction: Mandatory Thresholds for EU Export
RoHS: Restricts 10 hazardous substances in electrical and electronic products (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and four types of phthalates), with limits aligned with EU RoHS 2.0. China has issued the mandatory national standard GB 26572-2025 (effective August 2027), expanding the scope of control to these 10 items and introducing a green product label.
REACH: Regulates the Candidate List of Substances of Very High Concern (SVHC)—currently comprising 253 substances. A concentration exceeding 0.1% triggers notification obligations; hardware components exported to the EU generally require REACH testing and declarations.
These two standards represent the “market entry” level of environmental compliance for the EU and are mandatory requirements for most orders.
II. Management Systems and Declarations: Passports for Green Procurement
- ISO 14001 Environmental Management System: A factory-level environmental management certification and a common requirement for supplier qualification by major clients and government projects;
- EPD (Environmental Product Declaration): A Type III environmental declaration based on ISO 14025 that quantifies a product’s environmental impact across its entire lifecycle—EPDs for hardware components are increasingly required in EU construction projects and green building material tenders;
- EU Ecolabel: A voluntary ecological certification covering specific product groups; products bearing this label enjoy a competitive advantage in EU green procurement;
- Product Carbon Footprint Verification: Calculation of carbon emissions from raw material extraction to factory gate (or across the full lifecycle) and issuance of a verification report—following the implementation of the EU Carbon Border Adjustment Mechanism (CBAM), declaring export data for steel products is becoming a necessity.
III.
Domestic Green Products: Dual Benefits for Domestic Sales and Exports
China Green Product Certification: Covers hardware categories such as kitchen and bathroom fittings (faucets, angle valves, shower units, stainless steel sinks, floor drains, and hoses, in accordance with implementation rules CNCA-CGP-18) and aluminum alloy architectural profiles; the certification model involves type testing, initial inspection, and post-certification surveillance; Ten-Ring Certification (China Environmental Labelling): Covers products such as wooden and steel doors and frequently appears on domestic green procurement lists; Low-Carbon Product Certification: Implementation rules exist for categories such as aluminum alloy architectural profiles, utilizing a model of initial on-site verification followed by follow-up inspections.
IV. How to Choose: Tailoring the List to Target Markets and Customer Requirements
For exports to the EU: RoHS and REACH compliance are the baseline; for construction hardware, EPDs may be required depending on tender specifications. For exports to Southeast Asia: RoHS/REACH reports and international standards are generally accepted, though some countries (e.g., Malaysia) mandate specific certifications for electrical components. For domestic tenders: China Green Product Certification and the “Ten-Ring” Certification provide direct advantages in government procurement and green building assessments.
For major client factory audits: ISO 14001 certification is almost always a requirement.
When accepting orders, clarify exactly which “environmental certifications” the client requires and document these in the contract to avoid excessive investment or missed requirements.
V. Trends: Shifting from “Substance Restrictions” to “Carbon Accounting”
The focus of environmental compliance is shifting from limiting hazardous substances (RoHS/REACH) to quantifying carbon emissions (carbon footprint, EPD, CBAM). The EU’s CBAM already covers products such as steel, requiring exporters to develop carbon data accounting capabilities;
meanwhile, domestic green product certification systems are rapidly expanding their product categories. Industry experts recommend a “tiered, multi-pronged approach” to environmental certification: ensure baseline RoHS/REACH compliance; pursue green product certification or EPDs for target markets at the intermediate level; and prepare for carbon footprint accounting at the forward-looking level.
As certification lists evolve with policy changes, the key lies in accurately identifying exactly which certificates the client requires.
