If you’re shipping goods from Shenzhen to the United States, understanding accurate air freight timelines is crucial for supply chain planning. While many providers advertise “5-7 days,” real-world transit times depend on several key factors. Here’s what actually determines your shipping duration.

Realistic Timeframes by Service Type

• Transit: 3-7 business days

• Best for: Urgent documents, samples, critical components

• Process: Door-to-door with built-in customs clearance

• Key advantage: Fixed schedules and dedicated handling

2. Standard Air Cargo (Consolidated)

• Transit: 7-12 business days

• Best for: Regular inventory, larger shipments (100kg+)

• Process: Airport-to-airport with separate customs brokerage

• Cost saving: 30-50% cheaper than express options
