Shenzhen Zhengyuantai Technology Co, Exporter of electronic monitors, monitor accessories and related packaging, has built a narrowly focused trade pattern centered on the US West Coast, primarily exporting from Yantian (and occasionally Shekou) to Los Angeles/Long Beach and Newark, with occasional shipments to Vancouver; over the past two years it has executed roughly one to two shipments per month, averaging 0.5‑7 tonne per shipment and consistently using HS 852852 (monitor/display units) and HS 854011 (electrical apparatus) alongside occasional wood‑packaging codes (HS 441199). Its principal buyer, Impact Components, accounts for the overwhelming share of transactions, indicating a reliable, repeat‑order relationship and strong demand for monitor‑type products; this stability signals a dependable supply source for buyers seeking consistent monitor inventory. For customs brokers, the company’s documentation is highly predictable—identical HS codes, fixed loading ports and recurring destination ports simplify classification and clearance, while the steady TEU usage (typically 1‑1.5 per shipment) supports efficient routing and planning. Overall, Zhengyuantai offers buyers a focused, dependable monitor supply chain and presents customs brokers with low‑risk, high‑visibility shipments that facilitate smooth clearance processes.
