Hey there, if you’re an e-commerce seller looking to move inventory to US FBA via ocean freight, you’ve probably stared at a bunch of confusing, seemingly random rules Amazon has for packaging—and let’s be real, mess up those rules, and your entire shipment could get stuck at the warehouse, charged extra fees, or even rejected. As a US FBA ocean freight supplier, I’ve seen it all: sellers who accidentally label a pallet wrong and wait 2 weeks for Amazon to fix it, or whose boxes break open in transit because they used cheap tape, leading to a lost sale. Today, I’m breaking down exactly what packaging you need for FBA ocean freight, no corporate jargon, just real, actionable stuff I’ve learned working with hundreds of sellers over the years. US FBA Ocean Freight
First, let’s start with the big one: pallets. This isn’t just about shoving boxes on a wooden skid and calling it a day—Amazon has super strict pallet specs, and cutting corners here will cost you. First off, pallets have to be 48” x 40” standard GMA pallets, right? If you use a non-standard pallet (like a smaller 42” x 42” one), that’s a no-go. Wait, and they can’t be dirty, broken, or have any protruding nails or splinters—we once had a seller whose pallet had a loose nail sticking out, and Amazon refused to unload it, making us rearrange the entire pallet at the port, adding 3 days and $200 in fees. Also, pallets can’t weigh more than 1,500 lbs each, even if your total shipment is heavy. Oh, and if you’re using a heat-treated pallet, make sure the stamp is clearly visible—Amazon checks that, no exceptions.
Then, stacking on pallets: no overhang. That’s probably the most common mistake new sellers make. If a box sticks out past the edges of the pallet, when the forklift moves it, that box gets crushed, or it won’t fit in the FBA warehouse racks. We had a seller send a pallet with 2 inches of overhang on the top layer, and Amazon made us re-stack every single box at their warehouse, which delayed their delivery by a week. Also, pallets have to be stacked neatly, no pyramids, no loose boxes—everything has to be stable. If you’re stacking heavy stuff on top of light stuff? That’s a no too, because it’ll crush the lower boxes. We always advise sellers to put heaviest items on the bottom, lightest on top, to keep everything secure.
Next up, the boxes themselves. Amazon uses specific box rules for FBA, and for ocean freight, they’re even tighter because shipments are in a container, moving across the ocean, bouncing around. First, boxes have to be standard corrugated boxes, no used, beat-up boxes. Even if you have a perfectly good new box, if it has old shipping labels or writing on it, Amazon will get confused, so make sure boxes are clean. Also, when packing boxes, don’t overstuff them—boxes have to be rigid enough to hold their shape, even when stacked. If a box bulges or has too much tape, it won’t pass inspection. And weight per box: max 50 lbs, no exceptions. If a box is heavier than 50 lbs, your warehouse workers can’t lift it safely, and Amazon will reject it. We once had a seller send a box with 60 lbs of kitchenware, and the warehouse actually had to call a forklift to move it, which charged us extra, and the seller had to split the box into two, delaying their shipment.
Tape is another big one. You can’t use just any tape—Amazon wants 2 inches of heavy-duty packing tape, like acrylic or polypropylene tape, not cheap cellophane tape. You have to seal all edges of the box, not just the top. So for each box, you do the top flaps, bottom flaps, and make sure they’re all sealed tight. We once had a seller use cheap tape that came undone in the ocean, and half the boxes were open when they arrived, so Amazon had to inspect every item, adding $0.75 per unit in handling fees. That adds up fast, trust me.
Now, labels. This is where most sellers mess up, especially with ocean freight because you have two sets of labels: FBA labels and shipping labels. First, every single unit in your shipment has to have an FBA barcode (the FNSKU label) placed on it. But wait, not just any place—label has to be on a flat, unmarked surface, no curved edges, no overlapping with other labels. If you put it on a curved part of a bottle, the scanner can’t read it. Then, the pallet labels: every pallet needs two labels—one on the front, one on the side, so the scanner can read it no matter which way the pallet is facing. Pallet labels have to be 4” x 6”, printed on matte paper, no glossy paper, because glossy paper reflects light and the scanner can’t read it. Also, the labels have to be easy to scan—no wrinkled labels, no labels stuck under tape, no old labels on top. We had a seller whose pallet label was wrinkled because it got rained on at the port, and Amazon couldn’t scan it, so the pallet was sitting in a holding area for 5 days, delaying their entire inventory.
Wait, also, hazardous materials. If your product is anything that’s a hazmat (like batteries, aerosols, cleaning supplies), you can’t just ship it like regular stuff via ocean freight to FBA. Amazon has super strict hazmat rules, and you have to get proper packaging and certification. We work with a lot of sellers who accidentally ship a box of AA batteries and don’t label it as hazmat, and the entire container gets held up at customs, which costs thousands of dollars in storage fees. If you’re not sure if your product is hazmat, hit us up—we’ll help you figure that out, no guesswork.
Also, let’s talk about shrink wrap for pallets. You have to wrap the entire pallet in heavy-duty shrink wrap, at least 3 layers, from the bottom of the pallet up to the top. Don’t skimp here—we’ve seen pallets that weren’t wrapped come off the forklift and break open, and that’s a total nightmare. Also, no plastic stretch wrap that’s too thin, that will tear during transit. We always recommend using 80-gauge shrink wrap for pallets, that’s thick enough to hold everything together.
Wait, a few more small things that trip people up: no loose parts on pallets. If you have items that can fall off (like small parts for toys), you have to pack them in sealed boxes, not just leave them loose. Also, no liquids that can leak—if you’re shipping anything liquid, make sure it’s in a sealed, leak-proof container, and pack it so it won’t shift. We had a seller ship a bottle of perfume that leaked all over a pallet of clothes, and Amazon charged them $1,200 in cleaning fees, plus they lost a bunch of clothes that were ruined. That’s avoidable, just take the extra step to secure liquids.
And let’s talk about why this matters for ocean freight specifically, not just air or ground. Ocean freight is slower, so shipments are exposed to more variables: extreme temperatures, humidity, rough seas. So your packaging has to hold up longer, handle more movement. If you use flimsy boxes, they’ll break in the container. If your labels aren’t waterproof, they’ll fade or get washed off. We once had a seller who used regular paper labels and shipped to Asia first (wait no, US FBA ocean freight, so from their origin to US), the labels got wet during transit, and by the time they arrived at Amazon, they were unreadable. That’s a $5,000 mistake just because they cut corners on labels.
Now, I know this sounds like a lot, but it’s all stuff we handle every day. As your US FBA ocean freight supplier, we don’t just drop your shipment at the port—we help you make sure your packaging is compliant before it even gets on the ship. We have a pre-inspection step where we check all your pallets, boxes, labels, to make sure they meet Amazon’s rules, so you don’t get charged extra or delayed. Because at the end of the day, our job is to get your inventory to Amazon on time, intact, so you can start selling faster.
