Sea Freight vs. Air Freight: How to Choose for Your Next China Shipment

If you're importing from China, this is usually the first real decision you'll make: ship by sea, or ship by air? Get it right and you save money without sacrificing the timeline you need. Get it wrong and you either overpay for speed you didn't need, or wait weeks longer than your business could afford.

There's no universal right answer — it depends on what you're shipping, how much of it, and how soon you need it. Here's how to actually think through the decision.

The short version

Choose sea freight if your cargo is bulky, heavy, or not urgent — it's priced by volume (CBM), so it gets cheaper per unit the more you ship.

Choose air freight if your cargo is time-sensitive, lightweight, or relatively small in volume — it's priced by weight, and the speed advantage often outweighs the higher cost for smaller, urgent orders.

Cost: how each is actually priced

This is where most of the confusion comes from, because sea and air freight aren't priced the same way.

Sea freight is priced by volume (CBM — cubic meters), not weight. Our current rates:

• ₱10,500 per CBM from our Guangzhou warehouse
• ₱11,000 per CBM from our Yiwu warehouse
• Minimum charge of 0.12 CBM — anything below that ships at a flat ₱1,500

This means a shipment of dense, heavy items (like machine parts or tools) in a small box can be very affordable by sea, since you're paying for space, not weight.

Air freight is priced by chargeable weight — whichever is higher between the actual weight and the "volumetric weight" (a formula based on the size of your boxes, since bulky-but-light packages still take up valuable space on a plane). Our rate is ₱800 per kilogram of chargeable weight.

This means air freight punishes bulky, lightweight cargo (like inflatable products or bulky packaging) more than sea freight does — you're paying for the space it takes up, converted into an equivalent weight.

Speed: the real trade-off

Sea freight from China to the Philippines typically takes 4–5 weeks door to door, including origin handling, transit, and customs clearance. Air freight is dramatically faster — often days rather than weeks — but at a meaningfully higher cost per kilogram.

The real question isn't "which is faster" (air always wins) — it's whether the extra speed is worth the extra cost for this specific shipment. A restock of slow-moving inventory rarely justifies air freight rates. A time-sensitive order for a launch date, or a small high-value item, often does.

A practical way to decide

Ask yourself these three questions, in order:

1. Is this urgent? If your business genuinely can't wait 4–5 weeks, that alone may settle it in favor of air.
2. Is it bulky or dense? Heavy, compact cargo (tools, machine parts, dense retail goods) tends to favor sea freight's volume-based pricing. Light, bulky cargo (inflatables, large but light packaging) often costs more than expected by air, and sometimes even by sea if it blows past the CBM minimum.
3. What's the order size? Very small orders (a handful of kilos, well under the 0.12 CBM sea minimum) are frequently more practical by air, since the flat minimum sea charge can make tiny shipments disproportionately expensive relative to their size.

Still not sure? That's normal.

Most importers land somewhere in the middle — a mostly-sea strategy for regular restocking, with air freight reserved for urgent top-ups or new product launches. If you're not sure which fits your specific order, send us the details (item type, approximate weight/dimensions, and how soon you need it) and we'll tell you honestly which option makes more sense — not just quote whichever is more convenient for us.
