WILLIAMS SUZHOU CONTROLS CO LTD operates as a Supplier specializing in industrial control components, including solenoid valves, steel parts, and joystick assemblies, with frequent use of HS codes 391910 (plastic products) and 848120 (valve parts). The company demonstrates moderate transaction volume (typically 1-4 monthly shipments) primarily through Shanghai ports to Long Beach, CA (87% of shipments), with ARENS CONTROLS COMPANY LLC as its anchor partner (72% of recent shipments) alongside CURTISS WRIGHT CONTROLS INTEGRATED. Buyers benefit from consistent product focus on mechanical components and stable supplier reliability through recurring orders, though recent shipment declines (zero shipments in 7 of last 12 months) warrant demand verification. Customs brokers should note standardized routing (98% origin Shanghai), predictable HS code declarations, and occasional documentation inconsistencies in product descriptions (e.g., non-specific "hts" listings). The 6.0 average TEU/month capacity and centralized port operations suggest manageable clearance workflows, though rare Tacoma, WA diversions (4% of shipments) require contingency planning.
