Sea vs Air vs Rail vs Express from China

Every shipment from China comes down to the same trade-off: how fast you need the goods, and how much you’ll pay to get them there. There are four main ways to move cargo out of China. Ocean freight, air freight and express courier work on every lane. Rail works for Europe and the UK only. Each suits a different kind of shipment.

The quick comparison

Mode	Best for	How it’s usually priced	Typical transit (estimate)
Sea freight (FCL/LCL)	Large volumes, heavy or bulky goods, planned restocks	Per container (FCL) or per CBM (LCL)	About 2–7 weeks port to port, depending on lane (see below)
Air freight	Mid-size shipments that need to arrive in days	Per kg of chargeable weight	After departure: Urgent 1–3 days, Standard 5–10, Economy 10+
Rail freight	Europe and the UK, when sea is too slow and air too expensive	Per container or per CBM	Typically 18–25 days station to station to Germany
Express courier	Samples, small parcels, urgent restocks	Per kg of chargeable weight	After pickup: Priority 1–3 days, Standard 3–5, Economy 7+

Typical port-to-port sea transit by lane (estimates)

From Shenzhen or Ningbo to	Estimated port-to-port time
Los Angeles / Long Beach	About 2–3 weeks
New York / New Jersey	About 4–6 weeks
Vancouver	About 2–3 weeks
Felixstowe (UK)	About 4–7 weeks
Rotterdam or Hamburg	About 4–7 weeks

These are estimates, not schedules. Actual times depend on the carrier, the routing and the season. Asia–Europe sailings routed via the Cape of Good Hope can take longer.

Port to port isn’t door to door. Add roughly 1–2 weeks for pickup, export clearance, import clearance and final delivery. LCL shipments and inland addresses take longer, and so do peak periods like the weeks before Chinese New Year and Q4.

How chargeable weight works

For air and express, you rarely pay on actual weight alone. Carriers compare the actual (gross) weight with the volumetric (dimensional) weight and charge whichever is higher. That’s the chargeable weight.

Volumetric weight reflects how much space the cargo takes up. Multiply length × width × height in centimeters, then divide by the carrier’s divisor. Common examples:

• Express couriers often use 5,000 (cm³ per kg).
• Air freight commonly uses 6,000.

Divisors vary by carrier and service, so confirm them with your forwarder.

Worked example: one shipment, three ways of charging

Take a hypothetical shipment of 20 cartons, 60 × 50 × 40 cm each, weighing 15 kg each.

• Actual weight: 20 × 15 = 300 kg
• Volume: 20 × 120,000 cm³ = 2,400,000 cm³, or 2.4 CBM
• Air freight (÷ 6,000): volumetric weight 400 kg. Chargeable weight is 400 kg, since that’s higher than 300.
• Express (÷ 5,000): volumetric weight 480 kg. Chargeable weight is 480 kg.
• LCL sea freight: usually priced “weight or measure”, with 1 CBM treated as 1,000 kg, so this shipment is billed as 2.4 CBM.

The same 300 kg of goods is billed at 400 kg by air and 480 kg by express. The express rate per kg would need to be well below the air rate to come out cheaper, and at this size it rarely is. For light, bulky goods like pillows, plastic storage or products with a lot of packaging, sea or rail often beats the per-kg air price by a wide margin.

Packaging is often the easiest way to cut an air or express bill. Take the empty space out of cartons, and ask your supplier to use the smallest carton that still protects the goods.

Sea freight: FCL vs LCL

Ocean shipping is the default for volume, and it comes in two forms.

FCL (full container load)

You book a whole container, usually 20 or 40 feet, and pay per container whether it’s full or not. The container is loaded at the factory or a warehouse, sealed, and not opened again until destination unless customs inspects it. FCL makes sense once your cargo fills most of a container. There’s less handling, which means less risk of damage, and no waiting for other shippers’ cargo.

LCL (less than container load)

Your cargo shares a container with other shippers’ goods. It’s consolidated at a warehouse in China and separated again at destination. Pricing is by volume, usually per CBM with a minimum charge. LCL suits shipments that are too big for express and too small for a container. Expect longer transit than FCL, because of the consolidation and deconsolidation steps and the extra handling.

When LCL stops making sense

At some volume, a full container costs about the same as LCL and moves faster door to door. Where that break-even falls depends on current rates for your lane, so ask for both quotes when you’re in between.

Air freight

Air freight flies in the holds of passenger planes or on dedicated freighters. It usually needs customs clearance and delivery arranged at destination. On price and speed, it sits between express and sea.

Service levels, with typical times after departure:

• Urgent (1–3 days): the fastest option, at a matching price.
• Standard (5–10 days): a common choice for restocks and launches.
• Economy (10+ days): cheaper, with more flexible flight timing.

Air is a strong choice for higher-value goods, products with short selling seasons, and stock you need to avoid a stockout. Batteries, liquids, powders and magnets can be restricted or need extra documents. Declare them up front.

Rail freight (China to Europe and the UK)

Rail runs overland from China to Europe. It’s generally faster than sea and cheaper than air, so it suits cargo that’s too heavy to fly but can’t wait for an ocean voyage. UK cargo travels by rail to mainland Europe and finishes by road. As a rough guide, China–Germany (Duisburg) rail typically takes about 18–25 days station to station, and UK cargo about 25–35 days door to door, though both vary with routing and border congestion.

At YC Logistics, rail is offered only on the Europe and UK lanes, for both FCL and LCL cargo. It doesn’t serve the USA or Canada from China.

Some things to know:

• Rail routes cross several borders, so accurate documents matter even more than usual.
• Restrictions on some goods can be tighter than for ocean freight. Check before you book.

Express courier

Express means sending cargo through the DHL, UPS or FedEx networks. Pickup, transport, customs clearance and final delivery come as one service, with parcel-level tracking.

Express is the simplest option for:

• Product samples and pre-production approvals
• Small restocks of fast-selling SKUs
• Anything where a few days matter more than cost

For heavier shipments, the per-kg price usually makes air freight or sea cheaper. Check volumetric weight carefully, since express divisors are often less forgiving. As of September 2026, express parcels into the US owe duty whatever their value, because the US de minimis exemption is suspended.

A practical strategy: split the shipment

You don’t have to use one mode for the whole order. Many Amazon sellers and importers split it:

1. Send a small first batch by air or express so the product arrives quickly, starts selling and you can confirm quality.
2. Send the bulk by sea (or by rail to Europe) at a much lower cost per unit.
3. Time the sea shipment to arrive before the air batch sells out, using the port-to-port estimates above plus the door-to-door buffer.

This balances cash flow against stock risk. The trade-off is more coordination: two sets of paperwork, two deliveries, and labels that match each shipment plan.

How to choose in four questions

1. When do the goods really need to arrive? Work back from your selling date, then add a buffer for customs and delivery appointments.
2. What’s the chargeable weight? Compare actual and volumetric weight before deciding air is too expensive or sea is cheap enough.
3. What’s the product? Batteries, liquids, magnets and branded goods can limit your options.
4. Where is it going? Rail is an option for Europe and the UK. North America ships by sea, air or express.

Final thought

No mode is best every time. Sea usually wins for planned restocks, rail is worth pricing for Europe, and air and express cover urgent needs and small shipments. Get quotes for two modes side by side, with the same pickup and delivery terms, so you’re comparing like with like.

YC Logistics quotes sea, air, rail and express from pickup points across China. Send us your carton sizes and weights and we’ll price the options that fit.
