The US dedicated line is a specialized route for international express and logistics services from China to the United States; independently developed by domestic Chinese logistics companies, it offers two-way, door-to-door service. The transit time for this line is approximately 4 to 10 business days (excluding weekends).
Services are categorized into sea freight, air freight, and express delivery: sea freight options include LCL (Less than Container Load, where shipments from multiple sources share a container) and FCL (Full Container Load, where a single shipment occupies over 75% of the container's volume or 95% of its weight capacity); air freight services cover end-to-end logistics, including customs clearance at both origin and destination and tax-inclusive options; and express services leverage international logistics networks to integrate sea, air, and land transport resources, providing ancillary services such as customs declaration and warehousing.
The service scope encompasses general merchandise, daily necessities, electronic products, and compliant chemical products; the company also acts as an agent for international express carriers like DHL and UPS and operates dedicated lines to destinations including Japan and South Korea.
