Recently, updated EU environmental regulations including ESPR, revised RoHS and new WEEE directives have officially taken effect. Together with stricter import inspection rules worldwide, environmental compliance has shifted from an optional advantage to a mandatory access threshold for PCBA export. Non-compliant products risk customs detention, return shipments and heavy fines, pushing domestic PCBA manufacturers to accelerate green production transformation.

The latest rules impose tighter restrictions on hazardous substances. Besides six restricted heavy metals such as lead and cadmium, four types of phthalates are added to the mandatory control list. The SVHC candidate list under REACH has expanded to 233 substances. Any unqualified raw materials including circuit substrates, solder paste, ink or electronic components will result in the whole batch failing customs clearance. In addition, the EU requires mandatory carbon footprint filing throughout product lifespan and an 85% recycling rate for waste PCBA, forcing factories to implement green management across material selection and production.

Leading PCBA manufacturers have upgraded raw materials comprehensively, adopting halogen-free PCB substrates, lead-free solder paste and low-VOC flux while phasing out lead-based HASL in favor of eco-friendly surface finishes like OSP and ENIG. Factories upgrade waste gas treatment for reflow soldering and build complete material traceability archives with RoHS test reports for every batch.

The industry is undergoing reshuffling. Small manufacturers lacking eco-upgrades lose overseas orders continuously, while full-turnkey suppliers with mature green systems enjoy rising order volume. Industry insiders predict global access standards will keep tightening, and sound green supply chain and compliance testing will be essential for PCBA firms to sustain overseas business.
