TAI YUAN LIU NUO SHANG MAO YOU XIAN, an exporter specializing in handheld vacuum cleaners, cleaners and related household appliances, has demonstrated a focused trade pattern with a single dominant buyer, EXIDEA TRADE LLC, delivering 8–9 shipments per month from Shanghai (and occasionally Yantian) to major West Coast US ports (Los Angeles, Oakland, Long Beach). Monthly volumes average 70‑76 t, typically in 10‑11 TEU containers, using HS 850990 and 840610 codes consistently, which signals predictable product classification and routing. For prospective buyers, the supplier’s steady volume, repeated engagements, and narrow product portfolio suggest reliable supply capacity for small‑to‑mid‑size vacuum equipment orders and potential for scaling if diversified buyer base is pursued. For customs brokers, the uniform HS codes, consistent ports of loading/unloading, and regular shipment schedules facilitate streamlined documentation, low variance in customs clearance, and reduced risk of classification disputes, enhancing clearance efficiency for West Coast imports.
