SHANGHAI MAYILI CLOTHING TRADE CO LTD, an exporter of men’s casual apparel such as hoodies, t‑shirts, pants and mixed polyester‑cotton garments, ships almost exclusively from Shanghai (Port 57035) to Long Beach, CA (Port 2709), with BILLION CONCEPT DEVELOPMENT LIMITED as its recurring buyer. Over the past twelve months the firm averaged 1‑2 shipments per month, totaling roughly 2‑5 tonnes each, and consistently uses HS Codes 610910 (knit garments), 540710 (synthetic fibres) and occasional codes like 620343, indicating stable product classification. For prospective buyers, this pattern signals a dependable supply chain, focused product lines, and a single, high‑volume outlet that can support steady inventory replenishment. Customs brokers benefit from the predictable routing, repeat partner filings and limited HS‑code variety, which together facilitate smooth document preparation, low variance in duty calculations and high clearance efficiency at the Long Beach gateway.
