Where USPS-S moves.

Network hubs

Each hub runs twenty-four hours. They handle local pickup and delivery, consolidate cargo onto trunk lanes, and cross-dock between modes — air, ground, and ocean — when a route calls for it.

Lane map

A lane is a fixed route between two hubs, run on a known schedule with known equipment. We publish departure windows for every trunk lane; spot lanes spin up the moment volume justifies them.

Three classes of lane

• Trunk lanes — daily departures between major hubs (Singapore↔Amsterdam, Hong Kong↔Los Angeles). Fastest, most predictable.
• Regional lanes — every-other-day routes connecting trunk hubs to secondary cities. Local cutoff windows differ.
• Spot lanes — opened on demand for volume customers. Talk to ops before promising a delivery date on a spot lane.

Customs & duties

For international shipments we handle all customs paperwork, duty calculation, and clearance through our broker network. Customs status appears as a checkpoint on your tracking page — no surprise calls from a port asking for documents.

What we handle

• HS-code classification and commercial-invoice generation
• Duty and VAT calculation, paid on your behalf where pre-funded
• Broker submission and clearance follow-up
• Restricted-goods declarations (lithium batteries, dangerous goods)

What we need from you

• Description and declared value of the cargo
• Importer-of-record details if different from the recipient
• Any export licences for restricted destinations
