Shipping from China: Express, Air, Sea and Rail Explained
The four shipping methods at a glance
| Method | Typical transit time | Best for | Rough cost feel |
|---|---|---|---|
| Express courier (DHL, FedEx, UPS) | 3–7 days door to door | Samples, urgent orders, parcels under ~50 kg | Highest per kg |
| Air freight | 7–15 days door to door | 100–500 kg, time-sensitive restocks | High, but cheaper than express at volume |
| Sea freight | 25–45 days port to port | 1 CBM and up, non-urgent inventory | Cheapest per kg at volume |
| China–Europe rail | 18–28 days terminal to terminal | Europe-bound mid-size shipments | Between air and sea |
These timelines are door-to-door or port-to-port transit — they don't include production time, customs clearance, or last-mile delivery. Always ask your forwarder for the all-in timeline.
Express couriers: DHL, FedEx, UPS
Express is the default for samples and small urgent orders. You book online or through an agent, the courier picks up from the supplier, and the parcel arrives at your door with customs brokerage typically included.
When to use it: samples, documents, urgent replacements, and orders under roughly 50 kg where speed matters more than cost.
What to watch: express rates climb steeply with weight. A 2 kg sample parcel might cost $30–60; the same goods at 100 kg could cost more than air freight for the whole lot. Express couriers also have stricter rules on batteries, liquids, and magnetic items — check before your supplier ships.
Practical tip: many suppliers have discounted courier accounts and can ship samples cheaper than you can booking direct. Ask the supplier for their express quote before arranging your own pickup.
Air freight: the middle ground
Air freight moves your goods on commercial cargo flights (or freighters) via a freight forwarder. It's slower than express because of consolidation, airport handling, and customs on both ends, but dramatically cheaper per kilogram once you're past roughly 100 kg.
When to use it: restocking a fast-selling product, shipments of roughly 100–500 kg, or anything where 2–4 weeks of waiting for sea freight would cost you more in lost sales than air freight costs in freight.
How it's priced: airlines charge by chargeable weight — the greater of actual weight and volumetric weight (see below). Air freight rates are quoted per kilogram and fluctuate with fuel prices, season, and route. Your forwarder quotes an all-in rate including fuel surcharges, security fees, and terminal handling — make sure the quote itemizes these so you can compare.
Sea freight: FCL vs LCL
Sea freight is how most of the world's goods move, and it's the cheapest option per kilogram for anything substantial. You need to understand its two modes:
FCL (Full Container Load): you rent an entire container. Standard sizes are 20-foot (about 28 CBM usable) and 40-foot (about 58 CBM usable). You pay a flat rate for the container whether you fill it or not. FCL makes sense when your goods fill most of a container — roughly 15+ CBM for a 20-footer.
LCL (Less than Container Load): your goods share a container with other shippers' goods. You pay per cubic meter (CBM), typically with a 1 CBM minimum. LCL is the right choice for shipments too small for FCL — say 1–10 CBM.
The LCL catch: shared containers mean extra handling. Your goods are trucked to a consolidation warehouse, loaded with others' goods, unloaded at destination, deconsolidated, and then released. Each touchpoint adds days and a small damage risk. LCL transit is typically a week or more longer than FCL on the same route, and per-CBM rates are higher than the equivalent FCL rate. If you're consistently shipping 10+ CBM, price out FCL — the crossover point surprises many buyers.
Sea freight timelines: China to US West Coast is typically 12–18 days on the water; to US East Coast 25–35 days (often via Panama); to Europe 25–40 days depending on the port. Add roughly a week on each end for booking, loading, customs, and inland transport. When someone says "sea freight takes a month," they usually mean port to port — plan for 6–8 weeks factory to warehouse.
China–Europe rail: the in-between option
Rail freight runs from Chinese inland hubs (Chongqing, Chengdu, Xi'an, Zhengzhou, Yiwu) to European terminals (Duisburg, Hamburg, Warsaw, Madrid). Transit is typically 18–28 days terminal to terminal — roughly twice as fast as sea, roughly half the cost of air.
When to use it: you're shipping to Europe, your goods are too heavy for air but you'd like them faster than sea, and your volumes fit rail constraints (rail works in both FCL-style containers and LCL consolidation).
Limitations: rail only serves the China–Europe lane — there's no equivalent for the Americas. Capacity is tighter than sea, schedules less frequent, and some goods (notably certain batteries and chemicals) face restrictions. Not every forwarder offers rail, so ask specifically.
Volumetric weight: the formula that surprises beginners
Carriers don't just weigh your goods — they measure them. A carton of pillows weighs almost nothing but takes up real space on a plane, so carriers charge by volumetric (dimensional) weight when it exceeds actual weight.
The formulas:
- Express couriers: L × W × H (cm) ÷ 5000 = volumetric weight in kg
- Air freight: L × W × H (cm) ÷ 6000 = volumetric weight in kg (most airlines; some use 5000)
You pay on whichever is greater: actual weight or volumetric weight. This is called the chargeable weight.
Worked example: You're shipping a carton measuring 60 × 50 × 40 cm, actual weight 12 kg, by air freight.
- Volume: 60 × 50 × 40 = 120,000 cubic cm
- Volumetric weight: 120,000 ÷ 6000 = 20 kg
- Chargeable weight: max(12 kg, 20 kg) = 20 kg
You pay for 20 kg even though the carton weighs 12 kg. If the same carton went by express courier (÷ 5000), the volumetric weight would be 24 kg — even worse.
Why this matters: product and packaging design directly affect freight cost. A supplier who packs efficiently — smaller cartons, less air inside the packaging — saves you real money on every shipment. When comparing supplier quotes, ask for carton dimensions and weights, not just unit prices. A cheaper unit price in a bloated carton can lose to a slightly pricier unit in a tight carton once freight is added.
For sea freight, the equivalent concept is simpler: LCL is charged per CBM (cubic meter) of space used, so volume is everything and weight barely matters.
How to get a freight quote
Freight forwarders can't quote from "I want to ship some bags from China." Give them this information and you'll get accurate, comparable quotes:
- Product description — what the goods are (customs classification depends on this).
- Total weight and dimensions — per carton and total, or at least good estimates.
- Number of cartons — or total CBM for sea freight.
- Pickup address — city in China (usually the supplier's city or your agent's warehouse).
- Delivery address — your warehouse or address, with postal code.
- Incoterms — EXW, FOB, etc. (who handles what — see our Incoterms guide).
- Timeline — when goods will be ready, and when you need them.
- Special requirements — batteries, liquids, fragile goods, need for insurance.
Get 2–3 quotes with identical details. Quotes that aren't itemized (a single lump sum with no breakdown) can't be compared — ask for the breakdown: freight, fuel surcharge, terminal handling, customs brokerage, documentation fees, and last-mile delivery as separate lines. The cheapest headline number often hides fees that appear later.
Forwarder vs. carrier: as a small or first-time buyer, you work with a freight forwarder, not directly with airlines or shipping lines. The forwarder consolidates, books space, handles documentation, and clears customs. Direct carrier relationships only make sense at serious volume.
Realistic timelines (and peak-season reality)
Build your calendar from these typical ranges, then add buffer:
| Method | Typical door-to-door | Add buffer for |
|---|---|---|
| Express | 3–7 days | Customs inspection (1–3 days) |
| Air freight | 7–15 days | Consolidation wait, customs |
| Rail (China–EU) | 20–35 days door to door | Border crossings, terminal congestion |
| Sea LCL | 35–55 days door to door | Consolidation, deconsolidation |
| Sea FCL | 30–50 days door to door | Port congestion, chassis shortage |
Peak seasons that disrupt all of the above:
- Chinese New Year (Jan/Feb, dates vary): factories close for 2–4 weeks; the rush before the holiday congests everything for weeks prior. Ship early or wait.
- August–October: the pre-holiday retail rush (Halloween through Christmas goods). Rates spike — ocean freight can double — and space gets scarce.
- Golden Week (early October): a shorter but real disruption.
Peak-season surcharges are normal and legitimate — your forwarder should disclose them upfront, not discover them on your invoice. If a quote seems too good during peak season, something is missing.
A brief note on Incoterms
Your shipping quote depends on the Incoterms you agree with your supplier — EXW, FOB, CIF, DDP, and the rest define exactly where the supplier's responsibility ends and yours begins. This affects what your forwarder needs to arrange and what your quote should include.
The short version: on your first orders, DDP (supplier delivers to your door, all costs included) is simplest; as you scale, FOB (you take over at the Chinese port) usually gives better control and pricing. For the full explanation — who pays for what, where risk transfers, and the misunderstandings that cost beginners money — read our dedicated Incoterms guide.
Frequently asked questions
Should I let the supplier arrange shipping or use my own forwarder?
For first orders, letting the supplier arrange shipping (often quoted as CIF or DDP) is simpler. As volumes grow, your own forwarder usually gets better rates and gives you control over the timeline — supplier-arranged freight is a common place for hidden markups. Either way, get the arrangement in writing with the Incoterm specified.
How do I find a reliable freight forwarder?
Ask other importers in your niche, check forwarder directories and reviews, and interview 2–3 candidates with a real shipment scenario. Good signs: itemized quotes, proactive communication, experience with your product type, and their own offices or strong partners at both ends. Red flags: lump-sum quotes, slow responses during the sales process (it only gets worse), and reluctance to put terms in writing.
Do I need cargo insurance?
For sea and air freight, yes — typically inexpensive (roughly 0.3–0.5% of cargo value for basic coverage). Carrier liability for loss or damage is limited by international convention to amounts far below your goods' value. Express couriers include basic liability with options to declare higher value. Insure any shipment you can't afford to lose.
What documents do I need for customs clearance?
Typically: commercial invoice, packing list, and bill of lading (sea) or air waybill (air). Depending on the product and destination: certificates of origin, product-specific certifications (CE, FCC, etc.), and import licenses for regulated goods. Your forwarder or customs broker handles filing — your job is making sure the supplier provides accurate documents.
Why did my forwarder quote two different prices for the same shipment?
Usually the difference is chargeable weight calculation, included vs. excluded surcharges, or different service levels (direct vs. transshipment, premium vs. deferred). Ask both forwarders for fully itemized quotes on identical terms, and the discrepancy will reveal itself.
Can I ship batteries or liquids from China?
Yes, with restrictions. Lithium batteries ship under dangerous-goods rules (UN38.3 testing, specific packaging and labeling) — most forwarders handle compliant battery shipments routinely, but expect surcharges. Liquids, aerosols, and magnetic items face carrier-specific rules. Declare them accurately; misdeclared dangerous goods can get your shipment seized and earn you carrier blacklists.
