Exporting circuit boards to the EU must comply with ROHS 2.0 (2011/65/EU) and subsequent amendments (such as the addition of 10 restricted substances), which primarily focus on controlling the content of hazardous substances in electrical and electronic products. Below is the complete testing process, key requirements, pitfalls to avoid, and recommended institutions, applicable for listing on EU cross-border platforms such as Amazon and eBay:
1. Core Requirements of ROHS (Essential for Circuit Boards)
1. List of Restricted Substances (Latest version for 2024, total of 10 items)
| Substance Category | Limit Requirement (by weight) | Common Risk Points in Circuit Boards |
|---|---|---|
| Lead (Pb) | ≤0.1% (1000ppm) | Solder, coatings, electronic component pins |
| Mercury (Hg) | ≤0.1% (1000ppm) | Fluorescent lamps, sensors (some older components) |
| Cadmium (Cd) | ≤0.01% (100ppm) | Batteries, connectors, plastic housings |
| Hexavalent Chromium (Cr (VI)) | ≤0.1% (1000ppm) | Metal coatings (e.g., chrome-plated screws, brackets) |

| Polybrominated Diphenyl Ethers (PBDEs) | ≤0.1% (1000ppm) | Flame-retardant plastics, circuit board substrates |
| Di(2-ethylhexyl) phthalate (DEHP) | ≤0.1% (1000ppm) | Plastic housings, wires, adhesives |

2. Scope of Application
All circuit boards in Electrical and Electronic Equipment (EEE) exported to the EU, including: consumer electronics (phones, computers), home appliances, industrial control equipment, automotive electronics, etc.
2. Complete ROHS Testing Process for Circuit Boards (6 Steps to Implement)
Step 1: Product Disassembly and Bill of Materials (BOM) Organization
- Core Action: Disassemble the circuit board into independently testable materials to avoid mixed testing that could invalidate results.
- Must Disassemble Materials: Circuit board substrate (PCB), solder, electronic components (resistors, capacitors, chips), connectors, plastic housings (if integrated), wires.
- Output: Detailed BOM list (including material names, materials, suppliers, quantities), indicating potential risk substances for each material (e.g., solder corresponding to “lead”).
Step 2: Choose Testing Plan (Based on Cost and Risk)
| Testing Plan | Applicable Scenarios | Advantages | Disadvantages |
|---|---|---|---|
| Full Item Testing | First export, high-risk materials (e.g., solder from unknown suppliers), strict platform requirements | Accurate results, 100% compliance with requirements | High cost (full item testing for a single material is about 500-1500 RMB) |
| Targeted Testing | Known material risk points (e.g., only concerned about lead in solder) | Low cost, high efficiency | May overlook untested risk substances |
| Sampling Testing | Mass production, stable materials (same supplier, same batch) | Reduces testing costs | Must ensure sampling representativeness (sampling according to EN 62321 standard) |
| Supplier Declaration (DoC) + Sampling | Long-term cooperative suppliers, materials with ROHS certification | Saves time and cost | Must verify the authenticity of the supplier’s DoC, higher risk |
Step 3: Choose a Compliance Testing Institution (Key Pitfalls)
- Qualification Requirements: Must have CNAS Certification (China National Accreditation Service for Conformity Assessment) and CMA Certification (China Metrology Accreditation), and the testing report must be recognized by the EU (e.g., compliant with EN 62321 testing standards).
- Recommended Institutions
- Domestic third-party (e.g., Huancaiwei Testing): Lower cost, 7 working days cycle, suitable for budget-limited small and medium sellers.
Step 4: Sample Submission and Testing Implementation
- Sample Requirements:
- Each disassembled material must provide sufficient samples (e.g., PCB must be 5×5cm, solder must be over 5g, electronic components must be 3-5 per batch).
- Samples must be labeled with material name, batch number, and supplier to avoid confusion.
- Testing Standards: Execute according to EU EN 62321 series standards (e.g., EN 62321-4:2018 tests for lead, cadmium, mercury; EN 62321-5:2019 tests for hexavalent chromium, etc.).
Step 5: Obtain Testing Report and Rectification (if not qualified)
- Qualified Results: Receive testing report (in Chinese and English, must include institution seal, CNAS/CMA logo, testing standards, limits, actual values), report validity is usually 1 year (if materials or suppliers remain unchanged, can continue to use).
- Rectification for Non-Compliance:
- Trace back to the supplier of non-compliant materials, request replacement with ROHS compliant materials (e.g., lead-free solder, environmentally friendly plastics).
- Re-test the replaced materials until all items are compliant.
- If the substrate (e.g., PCB) is non-compliant, the supplier must be changed (preferably choose PCB manufacturers with ROHS certification).
Step 6: Prepare EU Declaration of Conformity (DoC) and Listing Preparation
- Core Action:
- Have the manufacturer (or authorized representative) sign the EU Declaration of Conformity (DoC), which must include: product name, model, manufacturer information, testing report number, applicable directives (ROHS 2.0 2011/65/EU), and signing date.
- Organize the complete set of compliance documents: testing report + DoC + BOM list + supplier qualification certificates (if any), keep for reference (EU customs or platforms may conduct random checks).
3. Key Pitfalls Guide (Common Issues for Cross-Border Sellers)
- Avoid Mixed Testing: For example, if solder and PCB are mixed for testing, if results exceed limits, it is impossible to pinpoint the specific non-compliant material, requiring re-disassembly and testing, wasting time and costs.
- Do Not Rely on Supplier Verbal Promises: Always require suppliers to provide ROHS testing reports for their materials, or conduct your own sampling to avoid having entire batches detained due to non-compliant supplier materials.
- Pay Attention to Batch Consistency: Different batches of materials for the same product must be tested separately; if suppliers or material specifications change, re-testing is required (platforms may randomly check different batches).
- Distinguish ROHS from REACH: ROHS targets hazardous substances in electrical and electronic products, while REACH is the EU chemical regulation (some circuit board materials may involve REACH substances of very high concern (SVHC), requiring additional REACH testing based on product type).
- Report Validity Period: If materials or suppliers remain unchanged, the report can be used for 1 year; if there are changes, re-testing is required to avoid using expired reports that could lead to compliance failure.
4. Cost and Cycle Reference (2024 Market Conditions)
| Item | Cost Range | Cycle Range |
|---|---|---|
| Full Item Testing for Single Material | 500-1500 RMB / item (based on material complexity) | 2-6 working days |
| Complete Testing for Circuit Boards (including 5-8 types of materials) | 3000-8000 RMB | 3-7 working days |
| DoC Preparation | Free (testing institutions can assist) or 500-1000 RMB | 1 working day |
5. Conclusion
The core of ROHS compliance for circuit board exports to the EU is “Material Disassembly + Compliance Testing + DoC Declaration”, with key points being to organize the BOM list in advance, choose qualified testing institutions, avoid mixed testing, and not rely on supplier verbal promises. It is recommended to choose full item testing for the first export, and subsequently optimize the testing plan based on material stability to reduce costs.
If you need to expedite customs clearance or platform listing, prioritize choosing Huancaiwei Testing Institution to ensure report recognition; domestic CNAS certified institutions offer better cost performance. After completing the testing, be sure to keep the complete set of documents to respond to random checks by EU customs or platforms.
