Landed Cost Per Unit: From Container to Amazon Check-In

By Bernardo Campelo, Forbes Business Council E-Commerce Leader and Founder of PrepVia, an Amazon SPN Certified prep center.

A buyer who moves a full container at a time, not a handful of pallets, does not need another quote. He needs the complete worksheet: the landed cost per unit, from the invoice he pays the factory to the moment that unit is available for sale on Amazon. Ask around for that number and you get pieces, a freight rate here, a labeling fee there, but rarely the whole calculation.

That gap is not an accident. Every party in the chain publishes its own number and stops there. The factory quotes a unit price. The freight forwarder quotes a container rate. The customs broker quotes an entry fee. The prep center quotes a per-unit labeling charge. Amazon publishes a fee schedule of its own. Nobody hands a buyer one document that adds all of it together, and a buyer who does not build that document himself is pricing his own product on a guess.

So this is that document. One worked example, a single 20-foot container carrying 12,000 units of a single SKU, every cost line from the factory floor to the moment the unit checks in at an Amazon fulfillment center. Then the same worksheet, run again at 3,000 units, because the number that matters is the cost per unit, not the total cost of the container, and that number moves more than most sellers expect once the order shrinks.

Why Large Buyers Now Ask for the Full Worksheet

Asking for the full worksheet is not unusual in 2026. Ocean freight rates have swung sharply over the past two years, tariff schedules have changed more than once, and Amazon revises its own fee card on a set calendar rather than leaving it flat. A buyer choosing between ocean and air, or between a full container and a partial one, is choosing under conditions that shift under him, and a rough estimate no longer holds up across a full order cycle.

Large buyers ask for the full worksheet because a partial one hides the decision that actually matters. A freight quote alone cannot tell a buyer whether a full container is worth waiting for. A prep quote alone cannot tell him whether a SKU is worth importing at all at his current order size. Only the complete stack, product cost through Amazon check-in, answers the question he is actually asking.

What a True Landed Cost Includes, and What It Does Not

Landed cost per unit is not the same question as true profit per ASIN, which starts after the unit is already sitting inside a fulfillment center and asks what remains once Amazon’s referral and fulfillment fees, advertising spend, and returns are subtracted. We covered that side of the math separately in true profit per ASIN. Landed cost per unit is also not the invoice a 3PL sends after a shipment has already been received and processed, which we broke down in a 3PL invoice, line by line.

Landed cost per unit answers the question that comes before both of those: what does it actually cost, all in, to move one unit from the factory floor to a state where Amazon will accept it for sale. That includes the import side of the journey, ocean freight, insurance, duty, and customs clearance, along with the domestic side, drayage, unloading, prep, materials, storage, inland freight, and the placement fee where it applies. Everything after the unit is listed belongs to a different calculation.

The Worked Example: One Full Container, 12,000 Units

The example below uses a single SKU: a compact kitchen organizer, 6 by 5 by 4 inches, weighing 0.9 pounds per unit. Packed 30 units to a carton and roughly 40 cartons to a pallet, the shipment fills 400 cartons across 10 pallets, at approximately 840 cubic feet of total volume, a load that fits comfortably inside one 20-foot ocean container. The factory price is set at $1.35 per unit, FOB origin, before any freight, duty, or domestic cost is added.

Every number below is an illustrative example, not a quote. Ocean freight, marine insurance, import duty, and customs clearance fees move with the market, the lane, the product’s HTS classification and, for duty, the country of origin, so treat the figures noted below as a starting point to confirm with your own freight forwarder and customs broker. The 10% duty line in particular is a placeholder, not the rate of any real origin. Since 12:01 a.m. Eastern on July 24, 2026, the Section 301 forced labor action (91 FR 47318) adds 12.5% for goods of China and Vietnam, on top of the HTS rate and with listed exemptions, so a container from either country will usually carry a larger duty line than the one below. Container unloading, FNSKU labeling, poly bagging, and storage are the prep center’s own lines, and each prep center sets its own rates, so the tables below list them without a rate and leave them out of the totals: add the figures from your own quote.

The Full-Container Landed Cost, Line by Line

Twelve thousand units, one container, factory price through Amazon check-in.

The total for the container, before the four prep-center lines, comes to $28,495.00. Divided across 12,000 units, that is $2.37 per unit before your prep quote is added, before Amazon’s referral and fulfillment fees are subtracted and before the unit has sold a single time.

Where the Money Actually Goes

Broken into buckets, the $28,495.00 splits roughly as follows. The factory price of the product itself accounts for 57 percent. Freight, insurance, duty, customs clearance, and drayage together account for 26 percent. Domestic freight to the fulfillment center and the placement fee together account for the remaining 17 percent. Unloading, prep and materials, and storage come on top, from the prep center’s quote.

Two things stand out in that split. Everything that is not the product itself, the import side plus domestic freight and the placement fee, already comes to 43 percent of the subtotal before the prep center adds a single line. And the prep-center lines, unloading, labeling, bagging, and storage, are the ones a seller can actually shop and compare between vendors, so compare them as a set, line by line, not on the labeling rate alone.

The Same Shipment at 3,000 Units

Now run the identical SKU at a quarter of the volume: 3,000 units instead of 12,000, still moving through the same 20-foot container because the buyer does not yet have enough volume to fill one alone. The product cost, the FNSKU label, the poly bag, and the Amazon placement fee all scale down cleanly, because each one is priced per unit. Insurance and duty scale down as well, because both are priced against cargo value, and the value of 3,000 units is a quarter of the value of 12,000.

Ocean freight, drayage, container unloading, and customs clearance fees do not scale down. They are charged per container or per shipment, set by the freight forwarder, the trucking company, the customs broker and the prep center, and they cost nearly the same whether the container carries 3,000 units or 12,000 (the merchandise processing and harbor maintenance fees inside customs clearance move with cargo value).

The Low-Volume Landed Cost, Line by Line

Three thousand units, the same container, the same prep-center lines left out of the total.

The total for this shipment, before the four prep-center lines, comes to $11,431.00. Divided across 3,000 units, that is $3.81 per unit, a full $1.44 higher than the same SKU at full container volume.

Why the Flat Charges Do Not Shrink With Your Order Size

The Three Charges That Stayed Exactly the Same

Ocean freight, drayage, and customs clearance fees total $5,610.00 in both scenarios above, to the dollar. At 12,000 units, that $5,610.00 works out to roughly $0.47 per unit. At 3,000 units, the identical $5,610.00 works out to $1.87 per unit, four times the per-unit cost for the same total charge. That single shift accounts for $1.40 of the $1.44 per-unit gap between the two scenarios. Container unloading on a palletized load is billed the same way, per container, so the prep center’s unloading charge widens the gap further.

The remaining three cents comes from domestic freight to the fulfillment center, where a partial pallet still occupies a full pallet position on the truck. Ten pallets carried 12,000 units at roughly 17 cents each in freight. Three pallets carried 3,000 units at 20 cents each, because a pallet position does not bill by how full it is.

How to Use This Worksheet Before You Choose a Route

Before the next purchase order goes out, run your own numbers through the same categories: product cost, ocean freight, insurance, duty, customs clearance, drayage, unloading, prep and materials, storage, domestic freight, and the placement fee where it applies. Our guide to import and export logistics for Amazon sellers covers the customs and freight side of that list in more depth, and PrepVia quotes the prep and materials side per account on a free 15-minute call.

Three Numbers to Confirm Before You Trust the Worksheet

None of these numbers changes what the flat charges do to a small order. They only change where inside your own numbers the gap actually shows up.

Frequently Asked Questions

What is included in landed cost per unit for an Amazon FBA shipment?

Landed cost per unit is the sum of every cost paid to get one unit from the factory floor to a sellable state at an Amazon fulfillment center, divided by the number of units that arrive. That includes the factory price, ocean freight, marine insurance, import duty, customs clearance fees, drayage from the port, container unloading, prep and packaging materials, storage while the unit waits to ship, domestic freight to the fulfillment center, and the Amazon inbound placement fee where it applies. It does not include Amazon’s selling fees, advertising, or returns, which belong to a calculation made after the unit is already for sale.

Why does landed cost per unit rise so much on a small or partial shipment?

Several of the largest cost lines in an import shipment are charged per container or per shipment rather than per unit: ocean freight, drayage, container unloading, and customs clearance fees. When a buyer orders a quarter of a container’s worth of units, those charges do not drop to a quarter of their dollar amount, so the same total divided by far fewer units produces a much higher cost per unit. In the worked example above, ocean freight, drayage, and customs clearance alone move from roughly $0.47 per unit at 12,000 units to $1.87 per unit at 3,000 units.

What is the difference between landed cost per unit and true profit per ASIN?

Landed cost per unit covers what a unit costs to acquire and get into a sellable state at Amazon. True profit per ASIN starts from that landed cost and subtracts everything that happens after the unit is listed: Amazon’s referral and fulfillment fees, advertising spend, returns, and the cost of the working capital tied up in inventory. A seller needs both numbers, because a low landed cost on a product with a poor selling margin can still lose money, and a higher landed cost on a product with strong sell-through can still be the more profitable item.

How much does container unloading actually cost per unit?

It depends on how many units share the charge. On a palletized container, unloading is a flat charge per container that covers breaking down the load and moving cartons off the container onto the dock; a floor-loaded container is quoted by carton count instead. Because the palletized charge is set by the container, not by how many units are inside it, a container carrying only 3,000 units of a single SKU carries four times the unloading cost per unit of one carrying 12,000 units of the same SKU. PrepVia quotes container unloading per account on a free 15-minute call.

Should the Amazon placement fee be included in a landed cost calculation?

Yes, when the shipment plan is expected to trigger it. Amazon charges the inbound placement fee per unit when the seller chooses minimal shipment splits, sending the inventory to as few inbound locations as possible, or partial splits, which exist only for bulky items. The Amazon-optimized option carries no placement fee, but it requires at least five identical cartons or pallets per item and means shipping to several fulfillment centers. The fee is billed 45 days after the shipment is received, based on the quantities received, but it is still a cost of getting the unit onto the virtual shelf rather than a selling fee. The worked example assumes minimal splits; a single-SKU load packed in 400 identical cartons, like the one above, would also qualify for the Amazon-optimized option. Confirm the fee tier for the specific size and shipment plan before finalizing the worksheet, since the rate varies by size tier and by how the shipment plan is split.

What is a reasonable range for ocean freight and import duty on a container from Asia?

Both figures move with the market and with the product, so treat any single number here as an example rather than a quote. Ocean freight on a 20-foot container commonly runs from a few thousand dollars to well above that figure depending on the season, the carrier, and the origin port. Import duty depends on the HTS classification of the product and on its country of origin. Since July 24, 2026 the Section 301 forced labor action adds 12.5% for goods of China, Vietnam, Thailand, the Philippines and other economies, and 10% for goods of India, Indonesia, Malaysia and others, on top of the HTS rate and with listed exemptions; for a few economies, such as Japan, South Korea and Taiwan, it sets a minimum total rate instead of adding to it. Goods of China can also carry the earlier Section 301 duties, depending on the HTS code, and articles covered by Section 232 duties, such as certain steel, aluminum and copper products, pay those duties instead and are exempt from the forced labor action. Confirm both directly with a freight forwarder and a customs broker before building a worksheet you plan to rely on.

How can a seller lower landed cost per unit without cutting corners on prep?

The two levers with the most room are order volume and dwell time. Ordering closer to a full container spreads the flat per-container charges over more units, which is the single largest driver of the gap in the worked example above. Reducing the days a shipment sits at a prep center before shipping to Amazon lowers the storage line without changing anything about how the units are labeled or packed. Prep and materials are priced per unit and do not move much with either choice, so they are rarely where the real savings live. The placement fee is the exception worth checking: packing at least five identical cartons or pallets per item opens the Amazon-optimized option, which carries no placement fee.

Final Take

The full worksheet is the right thing to ask for, and the wrong thing to expect from anyone else. No single vendor in the chain, the factory, the freight forwarder, the customs broker, or the prep center, can hand a buyer that number, because each one only sees its own line. The worksheet has to be built by the buyer, once, before the purchase order goes out, not assembled after the container has already cleared customs.

The two scenarios above use the same SKU and the same freight forwarder, and still land $1.44 per unit apart before prep-center charges. Almost all of that gap comes from three charges, ocean freight, drayage, and customs clearance, that are billed by the container rather than by the unit, and container unloading at the prep center works the same way. A buyer who understands that distinction can make a genuinely different decision: wait to fill the container, consolidate with another SKU to share the flat charges, or accept the higher per-unit cost with eyes open because the inventory needs to move now.

None of those choices is right in every case. What is consistent is that the choice should be made on the full worksheet, not on the factory price or the freight quote alone. A seller who only prices the pieces he has already been quoted is, by definition, pricing the parts of the shipment that are easiest to quote, not the parts that decide whether the order makes money.
