When you’re sourcing apparel from Asia, one of the biggest decisions you face isn’t about fabric or factory — it’s about how your goods actually get to you. Two options dominate: air freight and sea freight. Each has a completely different cost structure, timeline, and risk profile. Choosing wrong can eat your margin or leave your warehouse empty before the season starts.
This guide breaks down what each shipping method actually involves, where the trade-offs are real, and how to decide which one fits your business right now.
The Core Difference: Speed vs Cost
Sea freight moves cargo on container ships. Air freight moves it on cargo planes. That difference alone shapes everything else.
| Factor | Sea Freight | Air Freight |
|---|---|---|
| Transit time (China to US West Coast) | 12–18 days | 3–5 days |
| Transit time (China to Europe) | 25–35 days | 5–8 days |
| Cost per CBM | $80–$300 | $3,000–$8,000+ |
| Minimum shipment | 1 CBM (LCL) or FCL (20’/40′) | Chargeable weight as low as 45 kg |
| Suitable for | Large volumes, non-perishable, steady demand | Urgent restocks, high-value items, samples |
Sea Freight: The Workhorse of Apparel Importing
For most apparel brands, sea freight is the default choice — and for good reason. When you’re importing thousands of units per order, the math heavily favors ocean shipping.
Less-than-Container Load (LCL) vs Full Container Load (FCL)
If your order doesn’t fill a 20-foot container (roughly 28 CBM usable), you share a container with other shippers via LCL. Your goods are unloaded and consolidated at the destination port. LCL rates are quoted per CBM and include a customs clearance fee, but watch out for handling surcharges that can add up.
FCL makes sense once you’re hitting around 15–18 CBM consistently. You pay for the whole container but avoid the handling and consolidation risk. For brands doing $50K+ orders per shipment, FCL is usually the better deal.
What Sea Freight Actually Costs
Ocean freight is just one component. Here’s what you’re actually paying when you ship by sea:
- Base ocean freight rate — the line haul from origin port to destination port
- Port handling fees (THC) — terminal handling charges at both ends
- Documentation fees — bill of lading, customs paperwork
- Customs clearance — broker fees, duties, taxes
- Last-mile delivery — port to your warehouse (often quoted separately)
- Insurance — usually 0.3–0.5% of cargo value for apparel
A realistic all-in rate from Shenzhen to Los Angeles runs $2,500–$4,500 for a 20-foot container in a stable market. Rates fluctuate with demand (they spike hard before Chinese New Year and during peak seasons), so locking in rates with your forwarder 4–6 weeks out is standard practice.
Air Freight: Speed at a Premium
Air freight costs 10–15 times more per unit than sea freight. You would never choose it as your default shipping method for apparel. But there are situations where the premium is absolutely worth it.
When Air Freight Makes Sense
- Urgent restocks: A best-seller suddenly out of stock with weeks left in the season. Air gets replacement inventory in 5 days instead of 6 weeks.
- Sample shipments: Tech pack samples or pre-production samples that need to land quickly for buyer review before bulk production is confirmed.
- High-value, low-volume orders: Premium streetwear or limited-run collections where the per-unit air freight cost is a small fraction of the retail price.
- Quality issue recovery: You received a sea shipment with defects. You air in replacement units while the sea shipment gets sorted.
- Seasonal misses: You miscalculated lead times and the sea freight window has closed. Air is your salvage option.
Air Freight Cost Structure
Air freight is charged by chargeable weight — the greater of actual weight and volumetric weight (length x width x height / 600 for most carriers). A pallet of hoodies might weigh 200 kg physically but volumetrically be 280 kg, so you’re charged for 280 kg.
Key costs include: air freight rate per kg, fuel surcharge, security surcharge, customs clearance, and delivery to your door (often called door-to-door or airport-to-door). For apparel from Guangzhou/Shenzhen to LAX, expect $3.50–$7.00 per kg in normal market conditions.
DDP Shipping: Who Bears the Risk?
We covered DDP shipping in detail in our last post, but it intersects with air vs sea in an important way: under DDP (Delivered Duty Paid), the seller carries the risk for the entire journey. That means if your sea freight container gets delayed at port, the seller absorbs those costs. If your air shipment is damaged in transit, the seller’s liability is capped by international conventions.
When comparing DDP quotes from suppliers, always ask whether the quoted DDP price is based on sea or air — because the risk the supplier is assuming under DDP is completely different for each mode.
Key Decision Factors for Apparel Brands
Here’s a practical framework for making the call:
1. Order Volume and Value
Calculate your cargo value per CBM. If your goods are worth $15,000+ per CBM and you need 5 CBM, the sea freight cost might be $1,500 while air might run $15,000–$20,000. That’s a 10x cost difference for a 2–3 week time difference. Most brands should take the sea route and plan better.
2. Inventory Model
Brands running made-to-order or pre-order models often use air because they don’t hold inventory and need fast turnaround. Brands running wholesale or stocked inventory should almost always use sea — they have the lead time built in.
3. Season Windows
If you’re selling to major retailers, your delivery window is non-negotiable. Build in a buffer. If your sea transit is 18 days to the West Coast, plus 5 days for customs and drayage, plus 3 days to your warehouse — you’re looking at roughly 26 days from container load. Plan for 6 weeks total to be safe, especially during peak season when ports get congested.
4. Product Type
Lightweight garments (t-shirts, underwear, socks) have a high volumetric-to-actual-weight ratio. This means air freight is relatively cheaper for these items since you’re paying by volumetric weight. Heavy items (denim, jackets, hoodies) are penalized by volumetric weight calculations.
5. Supplier Location
Not all factories are near major ports. If your supplier is 3 days by truck from the nearest port, that adds cost and time to sea shipments disproportionately. Air freight from a regional airport might actually be faster end-to-end even though the per-kg rate is higher.
The Hybrid Approach
Many established brands use both. The bulk of their inventory travels by sea on a planned schedule. They maintain a small safety stock buffer at their warehouse. And they keep an air freight budget for true emergencies.
This is especially common for hoodie manufacturers and brands with multiple seasonal drops, where the ability to restock quickly is part of the business model rather than an exception.
What Most Brands Get Wrong
- Treating shipping cost as a line item rather than a strategic decision. Shipping method affects your inventory planning, cash flow, and risk management — not just your per-unit cost.
- Underestimating port congestion. In peak periods (August–October for holiday, February–March post CNY), West Coast ports routinely see 5–10 day delays. Always add buffer time.
- Not booking ahead. Ocean freight bookings should be made 3–4 weeks before your cargo needs to be ready. Last-minute bookings get bumped and you end up paying premium rates or switching to air.
- Ignoring volumetric weight. Pack efficiently. Using smaller boxes or compressing your cargo can meaningfully reduce your air freight bill.
Summary: Making the Right Call for Your Brand
For most apparel brands importing from Asia, sea freight is the default — and should remain the default. The cost advantage is enormous, and with proper planning, the longer lead time is manageable.
Air freight is a tool for specific situations: urgent restocks, high-value products, or when you’ve miscalculated a lead time. Using air as your regular shipping method is a margin problem waiting to happen.
The brands that get this right treat shipping as part of their sourcing strategy, not just logistics. Build your production calendar around sea freight windows. Book early. Maintain a buffer. And keep air freight in your back pocket for when things go sideways — because at some point, they always do.
