7. Core Technical Pain Points & Solutions

Pain Point 1 – Lead in Solder (Non-compliant)

Problem: Control panel PCB has lead-based solder (Sn63Pb37). ROHS test fails (>0.1% lead).
Root cause: Supplier used leaded solder (cheaper).
Solution: Specify lead-free solder (Sn96.5Ag3.0Cu0.5 or SAC305). Request XRF test report.

Pain Point 2 – Cadmium in Contacts (Non-compliant)

Problem: Relay or contactor contacts contain cadmium (silver-cadmium oxide). Test fails.
Root cause: Supplier used cadmium contacts (longer life).
Solution: Specify cadmium-free contacts (silver-tin oxide or silver-nickel). Request ROHS certificate.

Pain Point 3 – Phthalates in PVC Cables (Non-compliant)

Problem: PVC cable insulation contains DEHP (phthalate). Test fails (>0.1%).
Root cause: Standard PVC contains phthalate plasticizers.
Solution: Specify phthalate-free cables (LSZH – Low Smoke Zero Halogen, or phthalate-free PVC). Request test report.

Pain Point 4 – No ROHS Documentation (Customer rejects)

Problem: Customer audit requests ROHS certificate. Supplier cannot provide. Order lost.
Root cause: Supplier did not maintain ROHS documentation.
Solution: Request ROHS certificate before shipment. Material declarations for each component. Test reports (XRF).

8. Risk Warnings & Mitigation

Risk 1 – Customs Rejection (EU Import)

Warning: EU customs tests product, finds lead >0.1%. Shipment rejected. Destruction or return.
Mitigation: Test samples before shipment (XRF). Request ROHS certificate. Use authorized representative in EU.

Risk 2 – Customer Audit Failure

Warning: Customer (EU) audits facility, finds non-ROHS components. Supplier delisted.
Mitigation: Maintain ROHS documentation. Regular testing (annual). Supplier audits.

Risk 3 – Regulatory Fine

Warning: Market surveillance authority finds non-compliant product. Fines up to €100k.
Mitigation: ROHS compliance documentation. Technical file. Declaration of Conformity.

9. Procurement Selection Guide

Step 1 – Specify ROHS requirement: Directive 2011/65/EU (ROHS 3). Includes phthalates (DEHP, BBP, DBP, DIBP).

Step 2 – Request ROHS certificate: For complete machine (not just components). Include list of restricted substances and their limits.

Step 3 – Request test reports: XRF test report for random sample. Send to accredited lab (SGS, TÜV, Intertek) for verification.

Step 4 – Verify component certificates: Motor ROHS certificate. Control panel ROHS certificate. Cable ROHS certificate (phthalate-free).

Step 5 – Check for exemptions: Some components may have ROHS exemptions (e.g., certain copper alloys, high temperature solder). Verify exemption valid.

Step 6 – Include in CE documentation: ROHS required for CE mark. Declaration of Conformity must reference ROHS.

10. Engineering Case Study

Project Background: An EU importer purchased pellet mills from China. EU customs tested one unit, found lead in solder (0.25%). Shipment rejected. 40 units destroyed.

Initial Problem: Control panel PCBs had lead-based solder (Sn63Pb37). No ROHS certificate. No test reports.

Root Cause Analysis: Supplier used leaded solder (lower cost). No ROHS compliance process.

EU customs rejection	Yes (40 units)	0
Customer audits	Fail	Pass
Test reports	None	XRF available

Investment: +7% per machine
Loss avoided: 40 units × $5,000 = $200,000

11. FAQ

Q1: What is ROHS for pellet machines?
Restriction of Hazardous Substances Directive (2011/65/EU). Limits lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and phthalates.

Q2: Is ROHS required for EU?
Yes – for CE marking. Pellet mills must comply with ROHS (electrical and electronic components).

Q3: What is the lead limit?
<0.1% (1000 ppm) by weight in homogeneous material.

Q4: What is the cadmium limit?
<0.01% (100 ppm) – stricter than other substances.

Q5: Are phthalates restricted?
Yes – DEHP, BBP, DBP, DIBP (added in ROHS 3, 2015). Limit <0.1%.

Q6: Do mechanical parts need ROHS?
Steel, cast iron, aluminum are exempt (homogeneous material exception). Coatings (paint, plating) must comply.

Q7: What is XRF testing?
X-ray fluorescence – non-destructive test for hazardous substances. Quick screening method.

Q8: What is the difference between ROHS and REACH?
ROHS restricts substances in electrical/electronic equipment. REACH restricts substances in all products (chemicals). Both required for EU.

Q9: Does ROHS apply to spare parts?
Yes – replacement parts must also be ROHS compliant.

Q10: Are there exemptions?
Yes – certain applications (e.g., high temperature solder, some copper alloys). Check Directive 2011/65/EU Annex III.

Q11: How to get ROHS certificate?
Supplier self-declaration with test reports (XRF or wet chemistry). Third-party certification optional.

Q12: How long is ROHS certificate valid?
As long as product unchanged. New batch requires new test if component supplier changes.

Q13: What is the penalty for non-compliance?
EU member state fines (€10k-100k). Product recall. Customs rejection.

Q14: Does China have ROHS?
Yes – China ROHS (similar but different marking requirements). For EU market, use EU ROHS.

Q15: Do I need ROHS for UK?
Yes – UK ROHS (based on EU ROHS) for Great Britain market.
