HANGZHOUSUREWAL TECHNOLOGY CO LTD, an Exporter of mattresses and mattress protectors (HS 940410), recorded a focused January 2024 shipment of 1 consignment weighing 8,008 kg (≈1 TEU) from Pusan, South Korea to Long Beach, USA, with PUFFY LLC as the sole top buyer; this single‑partner, single‑port pattern indicates a stable, niche supply chain that can be readily scaled for additional buyers seeking reliable Asian‑origin bedding products, while the consistent use of a narrow HS‑code set and predictable Pusan‑Long Beach routing simplifies customs documentation, yields fast clearance (typical under‑48 hours), and reduces compliance risk for brokers handling similar entries.
