Dedicated US sea freight services encompass both LCL (Less than Container Load) and FCL (Full Container Load) shipping. Depending on specific routes and transit time requirements, various product options have emerged, such as express sea freight (e.g., the Matson CLX route, with a port-to-port time of ~11 days and cargo pickup 13–16 days after departure; and the ZIM ZEX route, with pickup 18–22 days after departure) and standard sea freight (transit time of 25–32 days).
Dedicated US air freight services include logistics support such as customs declaration and inspection, warehousing and distribution, cargo insurance, and documentation handling, offering "double clearance" (customs clearance at both origin and destination) and tax-inclusive options. A common service model is "Air + Delivery" (air freight combined with local last-mile delivery), where goods are flown to the US and handed over to local courier companies for final delivery; the estimated total transit time is 7–10 days.
US express services utilize various logistics transfer methods to provide international logistics solutions, including sea, land, and air transport, warehousing, customs clearance, and insurance. Service categories are primarily divided into dedicated small-parcel lines and dedicated express lines. Dedicated small-parcel lines cater to e-commerce shipments weighing 0–20 kg, offering direct China-to-US service with a total transit time of approximately 6–10 days; the volumetric weight calculation method differs from standard rules. Dedicated express lines combine commercial express carriers with local postal services-such as using DHL for the first leg and USPS for the last mile-taking approximately 8–12 business days, with some providers offering virtual US tracking addresses.
In addition to single-mode transport, dedicated US services often offer multimodal transport solutions, integrating air, sea, and rail resources to provide customized door-to-door services for oversized or specialized cargo, such as furniture and machinery. Common value-added service models include double clearance with tax inclusion (DDP/DDU), FBA (Fulfillment by Amazon) first-leg shipping, and overseas warehouse transshipment.
