TOPCUT KNIFE CO LTD, an exporter of precision kitchen knives and related cutlery, shows a focused supply chain centered on the US West Coast and East Coast, delivering 10 shipments totaling roughly 53 t (≈53 000 kg) across the last three months. The company repeatedly ships from YANTIAN (China) to Los Angeles, Long Beach and Newark, with Thunder Group Inc. as its dominant buyer (7 of 10 shipments, accounting for over 80 % of weight), indicating a stable, high‑volume client relationship and predictable routing. Core HS codes (290516, 290512, 821591) are consistently applied, reflecting standardized product classification and facilitating smooth customs clearance. For buyers, TOPCUT offers reliable supply continuity, a narrow but deep product line in premium kitchenware, and a proven track record of meeting US import demand without major disruptions. For customs brokers, its repeat use of specific ports, consistent HS‑code allocation, and regular shipment volumes support efficient documentation preparation and predictable clearance timelines, reducing risk of delays or classification disputes. Overall, the firm’s narrow customer base and steady logistics pattern make it a dependable partner for US knife importers and an operationally straightforward client for customs service providers.
