Sea or air from China to the USA — transit, cost and cargo fit compared, with a decision framework for your shipment.
XCJD Logistics is a China-based international freight forwarder founded in 2011 — we quote both sea and air DDP so you compare landed cost, not just transit.
Sea vs air from China to the USA comes down to one trade-off: sea DDP in 25–35 days at the lowest cost per CBM versus air DDP in 5–10 days at a higher cost per kg. Express (3–7 days) covers parcels under 30 kg. The right choice depends on your deadline, weight and budget.
The mode decision is a cost-versus-time trade-off — and it is the single biggest driver of your freight bill. Booking air for bulk cargo, or sea for a restock that needed air, both waste money.
| Factor | Sea DDP | Air DDP | Express | | --- | --- | --- | --- | | Transit | 25–35 days | 5–10 days | 3–7 days | | Cost basis | CBM (volume) | kg (actual vs volumetric) | kg, under ~30 kg | | Best for | Bulk, FBA replenishment, furniture | Urgent restocks, high-value | Samples, small parcels |
Weight, dimensions, deadline, supplier city and destination. Sensitive cargo (batteries, machinery) needs specs for a pre-check.
Since 2011 we have modeled sea-vs-air decisions for 8,000+ shipments — including FBA restocks where the split strategy saved both time and cost. Our sea freight page and air freight page detail both services.
Send your shipment details and we return one quote with sea and air options side by side — fixed DDP prices, quoted within 24 hours.
Air DDP takes 5–10 days and suits urgent restocks and high-value goods. Sea DDP takes 25–35 days and is the most cost-efficient per CBM for bulk inventory and FBA replenishment.
Sea is typically the most cost-efficient per CBM for bulk cargo; air trades cost for speed. The exact gap depends on weight, dimensions and urgency — we compare both in your quote.
Air DDP takes 5–10 days door-to-door with clearance and duties included.
Sea DDP takes 25–35 days port-to-door via LAX/Long Beach, with clearance and duties included.
Express (3–7 days) suits parcels under 30 kg; heavier cargo moves by air DDP more cost-effectively.
For large volumes, we often recommend splitting — sea for the bulk and air for the urgent part. Ask us to model both.
Send weight, dimensions, deadline and budget. We recommend the mode that fits — not the most expensive option.
