Compliance is non-negotiable for cross-border trade. For the North American market, ensure products meet cUPC and ETL certifications. For Europe, CE marking and RoHS compliance for electronic components are essential. Key technical benchmarks include waterproof ratings of IPX5 for electrical boxes, anti-clogging suction fittings, and leakage protection switches. Always verify that the drainage diameter matches the destination country's plumbing standards (e.g., 1.5 inches for the US vs. 40/50mm for Europe).
