Shandong Sincere Hygiene Product Co, Exporter of sanitary pads and related hygiene items, has demonstrated a focused but limited export pattern, primarily serving Sheer Simple Laboratories Inc in the United States with quarterly shipments since late 2023. Core products are classified under HS 961220 (sanitary paper products) and occasionally HS 847690 (other machines), shipped from major Chinese ports such as Shanghai, Qingdao and Pusan and consistently off‑loaded at Seattle and Tacoma, indicating a predictable West Coast routing. For prospective buyers, the supplier shows dependable product quality and on‑time delivery for a niche high‑value hygiene segment, though its reliance on a single buyer suggests limited scalability and a need for diversification. For customs brokers, documentation is straightforward with recurring HS codes, stable port pairings and modest TEU usage (1.5‑4.0 per shipment), facilitating efficient clearance and low risk of classification disputes. Overall, the company offers reliable supply for niche hygiene products with clear customs pathways, but buyers should assess capacity expansion potential while brokers can expect routine processing with minimal variation.
