The same carton costs $3 to $6 a kilo by air and $0.60 to $1.20 a kilo by sea. Same box, same factory, same Amazon warehouse. Roughly five times the price for arriving about three weeks earlier. Amazon FBA shipping from China looks like a cost decision, so beginners shop it like one and take whatever is cheapest or fastest that week. On a recent client launch we landed 500 units at roughly $4,500 all in, about $9 a unit by the time it sat in a fulfillment center. That freight line moves the landed number more than most people expect, and it usually gets decided last, in a hurry, with the goods already finished.
01The three methods, and what each one really costs
There are three ways to move a pallet of inventory from a Chinese factory to an Amazon fulfillment center. We have used all three on client launches, and the price gap between them is wider than most beginners assume.
Air freight runs $3.00 to $6.00 per kilogram and lands in 7 to 14 days. This is the emergency option. We almost never use it, because it eats the margin you spent three months protecting during product research.
Fast sea runs $1.30 to $2.50 per kilogram and lands in 14 to 20 days. This is the one we reach for most often when inventory needs to move quickly. It’s the middle option beginners skip, usually because nobody told them it exists.
Normal sea runs $0.60 to $1.20 per kilogram and lands in 30 to 45 days. Cheapest per kilo, slowest on the calendar, and the right default for every order you planned properly.
Those are the ranges we plan against. Real rates move with fuel prices, the season, the specific lane, and how much space is on the water that month. Chinese New Year tightens capacity and pushes prices up for weeks on either side of it, so a January quote and an April quote for the same box can look like different products.
The gap worth noticing is the shape of it. Fast sea costs roughly double normal sea. Air costs roughly five times normal sea. You’re not picking between three similar options. You’re picking between a cheap one, a pricey one, and one that can cost as much as the goods inside the box.
Two more things beginners get caught by:
- Freight is priced on chargeable weight, not just actual weight. Carriers compare the real weight of your cartons against their volume and bill you on whichever is higher. A light, bulky product gets billed like a heavy one. If you bundled an extra item into the box for differentiation, you already changed this number.
- The quote and the landed cost are different things unless the quote is DDP. More on that in section 05, and it is the single most common place a beginner’s budget breaks.
That first point deserves a minute, because it’s where differentiation quietly meets freight. Sea freight on smaller orders is usually priced by the volume your cartons take up, and air freight compares actual weight against a volumetric figure and bills the higher one. Either way the size of the box matters as much as what’s inside it.
So every decision you made during sourcing shows up again here. On a sports and fitness launch we ran, the differentiation was a bundle: a hand band, a wrist band, a resistance band, and a small carry bag packed with the core product, all four visible in the main image. That product held first page rank from launch at a 20% price premium, with month one advertising cost of sale at 25%. It also made the carton bigger. A bundle that wins the click and then pushes your packed product into a higher FBA size tier, or adds a third to your freight bill, has handed back some of what it earned. Decide the bundle with the packed carton dimensions in front of you, not after the samples land.
02Why the slowest option is usually the right one
Normal sea is our recommendation for every normal scenario. Not a compromise, an actual recommendation. When you’re not in a rush and your inventory planning is on track, the cheapest method protects the margin on every single unit you sell for the next several months.
Put real numbers on it. Say your first order is 500 units and the packed cartons come to 300 kg total. Here’s the same shipment under the three methods, using the mid point of each range:
- Normal sea at $0.90/kg: about $270 total, or $0.54 a unit
- Fast sea at $1.90/kg: about $570 total, or $1.14 a unit
- Air at $4.50/kg: about $1,350 total, or $2.70 a unit
Air costs roughly $1,080 more than sea on that one order. That’s arithmetic on the rates above, not a quote, but the shape holds. On a product retailing at $25 with maybe $7 of net profit per unit after Amazon fees and cost of goods, paying an extra $2.16 a unit to arrive three weeks early has just taken about 30% of your profit for that entire batch.
This is why we say a shipping decision is really a margin decision. You do the hard work of finding a niche where the math clears 30% net, then hand a third of it back to a plane because the reorder went in late.
There’s a second cost people forget in the other direction. Inventory that arrives far too early sits in Amazon’s warehouses collecting monthly storage fees, and if it’s still sitting there past the long term thresholds, the bill gets much worse. We wrote the full breakdown of how those FBA storage fees stack up and what triggers the expensive tiers. The goal isn’t earliest or cheapest. It’s arriving close to when you actually need it.
We currently run Amazon stores doing $200k/month for paying clients, and the freight method on most of those replenishment orders is plain sea freight. The exciting option is almost never the correct one.
03Lead time is the number that actually picks your method
Most beginners choose a shipping method by looking at the quote. That’s backwards. The method gets chosen by a number you should have calculated weeks earlier, and once you have it, the decision usually makes itself.
Lead time is the total time from paying your supplier to having product available for sale. The formula is simple:
Manufacturing time + shipping time = total lead time
Work an example. Your supplier takes 20 days to manufacture. You use normal sea, which averages about 35 days. Your total lead time is 55 days. Almost two months between your money leaving and your inventory being sellable.
Now the rule that follows from it. With a 55 day lead time, you place your next order while you still have at least 75 days of inventory left in stock. Not 55. Seventy five, because you want a buffer for customs holds, factory delays, Amazon’s receiving queue, and the week your supplier goes quiet for a holiday you didn’t know about.
Days of stock is the other half of that number. Take the units you have on hand plus anything already inbound, then divide by your average daily sales over the last 30 days. Sell 12 units a day with 900 units sitting between your warehouse and Amazon’s, and you have 75 days. That’s your trigger, not a feeling about the inventory looking thin.
Run that calculation once a week and write the date down. Beginners check stock when Amazon sends a low inventory alert, which fires far too late to help. That alert is telling you to book air freight. The calendar would have told you to book sea freight a month earlier at a fifth of the price.
Beginners reorder when stock looks low. By then the only method that saves them is air, and air is what turns a healthy launch into a breakeven one. The expensive shipping bill is almost always a symptom of a reorder that went in three weeks late.
Two things make this worse than it sounds:
- Running out of stock costs more than the freight ever would. You lose rank you paid PPC money to earn, and getting it back is a second launch budget. A product going out of stock at month four is one of the more expensive mistakes we see.
- Your PPC keeps spending while you wait. We treat $50 a day as the operator floor for a launch ramp, which is about $3,000 over a 60 day push. Ads running against a listing that’s about to go dark is money burned twice.
So run the lead time calculation before you ever ask for a freight quote. If the answer is comfortable, book normal sea and move on. If the answer is tight, you now know exactly how tight, and section 04 has the splits we use.
04The split strategies we use when timing gets tight
You do not have to send everything one way. Splitting a shipment across two methods is the move that saves launches, and it’s the part of this almost nobody teaches beginners.
Here is how we decide, based on how much stock is left and when the listing goes dark.
You’re about to run out. This week. Split 20% air, 80% sea. The small air batch is expensive per kilo but it’s only a fifth of the order, so the total damage stays contained. It arrives in 7 to 14 days and keeps the listing alive. The other 80% follows by sea at normal cost and rebuilds the real inventory position behind it. This is the only scenario where we touch air freight at all.
You’re running low but you have some runway. Split 50/50 between fast sea and normal sea. Half arrives in 14 to 20 days to cover the gap, half arrives at 30 to 45 days at the cheaper rate. You get the speed where you need it and pay standard rates on the rest.
You need the whole order fast. Send 100% fast sea. Still far cheaper than air, and 14 to 20 days is fast enough for most situations that feel urgent. This is the option beginners reach past on their way to a panic air quote.
Everything is on plan. Send 100% normal sea and keep the margin.
The rule underneath all of it: never send 100% of your inventory by air. Not once. If the situation feels bad enough to justify it, the 20/80 split solves the same problem for a fraction of the cost, because the thing you actually need is a few units back in stock quickly, not the entire order.
One practical note on splits. Two shipments means two sets of cartons, two sets of documents, and two separate shipment plans inside Seller Central. Tell your freight forwarder you’re splitting before they build the invoice, not after. A split arranged at the last minute costs more than one arranged at the start.
Decide which units go in the fast batch as well. Send your best selling variation by the quicker method and let the slower movers come by sea. On a single SKU it makes no difference, but on a listing with three or four child variations, an even split of everything means the variation that actually sells still runs out, while stock of the slow one sits in a warehouse collecting storage fees.
05EXW vs DDP, and where the money hides
This is where beginner budgets break. A factory quotes you a unit price, you multiply it by your order quantity, and you write that number in your launch budget. Then a second bill shows up that you didn’t plan for.
EXW, or Ex Works, means the price covers the goods sitting at the factory door. Everything after that is yours. Inland trucking in China, export clearance, the ocean or air leg, US customs entry, duty, and the final delivery to an Amazon fulfillment center. Each of those is a real cost and some of them are hard to estimate before you’ve done it once. That EXW price is the number you use to compare suppliers against each other, which is exactly why we tell people to ask for it during supplier vetting on Alibaba. It’s a comparison tool, not a budget.
Duty is the line people underestimate most. The rate depends on how your product is classified, not on what you paid the factory, and two items that look almost identical in a catalogue can sit in different classifications at different rates. If you’re quoting EXW, find your product’s classification code and confirm the rate before you write the budget. Guessing here is how a launch ends up several hundred dollars short at exactly the moment the goods are stuck at a port.
DDP, or Delivered Duty Paid, is a single all inclusive price from the factory door to the Amazon warehouse, with US customs taxes and fees already inside it. The quote you accept is the amount you pay. That’s the whole appeal. For a first launch, when you’re trying to hold a budget together and you’ve never cleared customs before, the certainty is worth more than shaving a few percent off a line item you can’t predict anyway.
The vegetable chopper launch mentioned at the top was shipped DDP through Freightklan, our own shipping company. Five hundred units, roughly $4,500 landed, $9 a unit sitting in Amazon’s warehouse ready to sell. That $9 is a real landed number, not a factory quote plus a hopeful guess, which is what makes it usable for pricing decisions.
Here’s how the DDP invoicing actually runs, because the sequence matters:
- Factory pickup. Your cartons are collected from the factory and moved to our warehouse in China.
- Inspection and verification. The team physically checks and verifies the exact weight and dimensions of every carton. This is the step that decides your real bill.
- Final invoice. You get the all inclusive invoice before the shipment sails, so the number is accurate rather than estimated.
- Payment before departure. Payment is due before goods leave the China warehouse for the US.
Step two is the one worth understanding. Factories quote weights and dimensions from memory or from an old spec sheet, and they’re often wrong in a direction that costs you. Re weighing and re measuring every carton before the invoice is written means you’re billed on what’s actually in the boxes. Beginners who skip a verification step like this find out about the difference through a surprise charge after the goods are already moving, when they have no negotiating position left.
06How to get a quote that isn’t a guess
Freight forwarders can’t quote you properly without specific information, and a vague request gets a vague number that changes later. Send everything at once and you get a real quote back the same day.
First, get your destination address. You can’t ask for an accurate quote without knowing which Amazon warehouse the inventory is going to, because the inland leg inside the US is priced on that. The address comes from a shipment plan you create in Seller Central:
- Log in to Seller Central and hover over the Inventory tab.
- Click Shipments.
- On the Shipping Queue page, click the specific FBA shipment you created.
- Find the Ship To address on the shipment details. That’s your assigned fulfillment center.
Copy that address, including the warehouse code like LAX9 or FTW1, and send it to whoever is quoting you.
One warning that catches people. An Amazon shipment plan is only valid for 90 days from the day you create it, then it closes for inactivity. So create the plan when the goods are genuinely close to ready at the factory, not months ahead while you’re still waiting on production. Once the shipment moves, get the tracking IDs from your freight forwarder and submit them under the shipment tab so Amazon knows what’s coming.
Then send this list. All of it, in one message:
- Product name
- Manufacturer’s pickup address
- Amazon warehouse destination address and warehouse ID
- Total number of cartons
- Units per carton
- Weight of one carton
- Dimensions of one carton
- Preferred shipping method, air or sea
Now the part most sellers skip. Ask your manufacturer for a freight quote as well, and compare it against your forwarder’s number. Factories will happily arrange shipping and many of them add a comfortable margin to it, but not all of them do, and occasionally the factory genuinely has the better rate on a particular lane.
Across the students and clients who’ve run their quotes through our freight service, the saving has generally come in between 30% and 50% against the first number their manufacturer gave them. That’s a real gap, and it’s the reason we built the service. It’s also exactly why you should still collect both quotes and take the better one wherever it comes from. Anyone who tells you to stop shopping the price is selling you something.
07When to hand the freight off
Freight is a skill you only need a few times a year, and it punishes you for being rusty. If this is your first launch, doing it yourself once is genuinely worth it, because you’ll understand your own cost structure for every order after that.
Where it stops being worth it is when the numbers get big enough that a mistake costs more than the help. The pattern we see is that the first order teaches you the mechanics and the third order is where money starts leaking, because by then you’re tracking reorder timing across several SKUs with different lead times and different sales speeds. That’s a scheduling job more than a shipping job, and it’s the part that quietly decides whether you ever pay for air freight again.
Clients on our done with you tier get the freight handled inside the launch rather than as a separate problem, along with the reorder timing that stops the panic air shipment from happening. If you’d rather have someone run the lead time math and the customs side with you on the first order, book a discovery call and we’ll look at your specific product and timeline.
Frequently Asked Questions
How much does Amazon FBA shipping from China to the USA cost?
Plan on $0.60 to $1.20 per kilogram for normal sea freight, $1.30 to $2.50 for fast sea, and $3.00 to $6.00 for air. On a 300 kg shipment that’s roughly $270, $570, or $1,350. Rates shift with season, fuel, and lane, so treat these as a planning band and get a live quote before committing.
How long does sea freight take from China to Amazon?
Normal sea freight runs 30 to 45 days, and fast sea runs 14 to 20 days. Add your manufacturing time on top to get total lead time. Twenty days of production plus 35 days of sea freight is 55 days from payment to sellable inventory.
Should I ship my first Amazon order by air to launch faster?
No. Air freight can cost about five times what sea costs and it comes straight out of your net margin on every unit in that batch. The only time we use air is a 20% portion of an emergency restock, with the other 80% following by sea.
What’s the difference between EXW and DDP shipping?
EXW is the price of the goods at the factory door, with freight, customs, duty, and US delivery all still owed by you. DDP is one all inclusive price from the factory to the Amazon warehouse with US customs taxes and fees included. Use EXW to compare suppliers, use DDP to build a budget you can trust.
When should I reorder inventory from China?
Place the next order while you still have at least 75 days of stock left, assuming a lead time around 55 days. The extra buffer covers customs holds, factory delays, and Amazon’s receiving queue. Running out of stock costs you rank you paid PPC to earn, which is more expensive than any freight bill.
Should I ship product samples the same way?
No, samples go by courier and the logic is different. We ship samples to our team in Pakistan rather than the US or Canada, because it’s much closer to China, samples land in about a week, and the per sample shipping cost is noticeably lower. Budget around $150 per supplier for a sample, then verify quality in person before releasing the production order.
The Bottom Line
Amazon FBA shipping from China is a calendar problem wearing a cost problem’s clothes. Work out your lead time first, manufacturing plus shipping, then reorder while you still have 75 days of stock, and normal sea freight at $0.60 to $1.20 a kilo handles almost everything you’ll ever ship. Keep air freight for the 20% emergency slice and never for a full order. Ask for EXW when you’re comparing suppliers, ask for DDP when you’re building a budget, and get quotes from both your factory and a freight forwarder before you commit. Do that and the freight line stops being the thing that quietly takes a third of your margin on a batch you already worked hard to source.
