What Is Landed Cost? The Number Your Supply Invoice Doesn't Show You

If you have ever recorded a supply purchase in your books at the number printed on the invoice, this post is for you. It is the obvious thing to do. The invoice says $400, so the fabric cost $400, and you move on to something more interesting than data entry.

Here's the problem. The invoice price is what you agreed to pay the supplier for the goods. It is not what the goods cost you. Somewhere between the supplier's warehouse and your shelf, a second set of numbers attached itself to that order — and if those numbers aren't in your material cost, they aren't in your product cost, and they aren't in your price.

Landed cost, in one sentence

Landed cost is the total cost of getting a purchased item onto your shelf and ready to use.

That's it. The formula is unglamorous:

Landed cost = purchase price + freight-in + duties and import fees + currency and payment costs + handling and insurance + shrinkage allowance

Divide that by the quantity you can actually use, and you get landed unit cost — the number that belongs in your recipe, your bill of materials, and your pricing math.

The reason this matters isn't accounting hygiene. It's that every one of those add-on costs behaves differently from the purchase price. Freight scales with weight, not value. Duty scales with value, not weight. Fees are often flat per shipment, which means they punish small orders. If you're only tracking the invoice price, you're not just off by a bit — you're off in a direction, and the direction changes depending on what you ordered.

Meet Rae — a composite character, not a real customer; her business and every figure attached to her are illustrative, built to show how landed cost compounds. Rae makes leather bags. She buys veg-tan hides from a domestic tannery and solid brass hardware from an overseas supplier, and she has been pricing her work off the invoice numbers for two years. Her problems are the five below, in order.

Problem one: freight-in is part of the goods, not a separate bill

Rae's hide order shows $612 for twelve sides and, on the line below, $74 for shipping. She files the $612 under materials and the $74 under "shipping," which in her spreadsheet sits next to the postage she pays to send finished bags to customers.

Two different costs went into one bucket, and they point opposite directions.

Freight-in is the cost of moving goods toward you — supplier to your door. Freight-out is the cost of moving finished product away from you — you to your customer. Freight-in belongs in the cost of the material. Freight-out is a selling expense that has nothing to do with what a bag costs to make.

This isn't a stylistic preference. IRS Publication 334, the small-business tax guide, lists freight-in and containers under Line 39 — Other Costs in the cost-of-goods-sold calculation, alongside purchases and labor. Inbound freight gets capitalized into the value of your inventory and expensed through COGS when the item sells, rather than deducted separately the month the truck arrives.

For Rae, that $74 raises the cost of a hide from $51.00 to $57.17 — a bit over 12%. She has been quoting custom work off the $51.

Watch for the reverse case too. Some suppliers quote a delivered price with freight already baked in, others quote goods-only and bill shipping separately — that difference is what Incoterms (EXW, FOB, DDP and the rest) exist to pin down. Two suppliers quoting "the same price" on different terms are not quoting the same price, and only one of those quotes is already a landed cost.

The fix: when you enter a purchase, enter the shipping line on the purchase, not beside it. Every serious inventory system, including Ardent Seller, lets you attach freight to a purchase and roll it into the unit cost of what arrived. If you're on a spreadsheet, add a column called "landed unit cost" next to "invoice unit cost" and stop referencing the second one.

Problem two: the $800 exemption you remember is gone

This is the section that has changed most recently, and it's the one where old advice will actively cost you money.

For years, the practical rule for small importers was simple: shipments valued at $800 or less entered the United States duty-free under the de minimis administrative exemption. If you bought $300 of brass hardware from abroad, no duty, no entry paperwork, no fees. That assumption still sits underneath a lot of older advice for small importers.

That exemption has been suspended, through two separate rules that between them cover every way a box can reach you.

If your supplies arrive by commercial carrier — air freight, express courier, ocean, truck — the exemption is gone as of June 24, 2026, and those shipments now have to go through formal or informal entry like any other import (CBP Dec. 26-12, 91 FR 37789 (PDF)).

International mail lost the exemption the same day, under a companion rule CBP published alongside the first (CBP Dec. 26-13, 91 FR 37801 (PDF)). Don't be misled by the July 24, 2026 date attached to that second rule — that is when CBP's new postal entry process, with its own filing and bonding requirements, phases in. The duty-free exemption itself ended in June for both channels.

Both rules implement Executive Order 14324 of July 30, 2025, continued by Executive Order 14388 of February 20, 2026. One carve-out survives: the separate de minimis exemption for qualifying bona fide gifts. A carton of brass clasps invoiced to your business is not a gift.

Rae's brass hardware ships by courier from a European foundry — precisely the channel the first of those two rules covers. So what does her order carry now?

• Customs duty, at whatever rate your goods' tariff classification carries. Rates come from the Harmonized Tariff Schedule of the United States search tool. There is no universal rate — it depends on the ten-digit classification, and getting it right is the importer's legal responsibility. If your classification is genuinely unclear, that is what a customs broker is for.
• The merchandise processing fee (MPF), a CBP user fee. For fiscal year 2026, CBP set the ad valorem MPF rate at 0.3464% for formal entries, with a minimum of $33.58 and a maximum of $651.50; the automated informal entry fee is $2.69 (CBP Dec. 25-10, adjusted customs user fees, effective October 1, 2025 (PDF)). Note that minimum — on a formal entry, the MPF floor alone can exceed the duty on a small order.
• Entry type matters. Formal entry generally applies above $2,500, and to smaller shipments that don't qualify for informal treatment because of extra requirements or duties (91 FR 38007 (PDF)). Informal entry, where you qualify for it, is the cheaper and lighter of the two.
• A carrier disbursement fee. When UPS or FedEx pays your duty to CBP so your box keeps moving, they charge you for fronting the money — typically a percentage of the amount advanced with a flat-dollar floor. The floor is what stings on small shipments. Both carriers publish current figures (FedEx duties and taxes, UPS import fees); check them rather than trusting a number you read somewhere, including this one.

The practical consequence for a small maker is not that importing became impossible. It's that the fixed portion of import cost got much heavier relative to small orders. A $200 hardware order that once landed at $200 might now land at $250 or more once duty, MPF, and a disbursement fee stack up. Ordering four times a year instead of twelve is suddenly a real cost decision rather than a cash-flow preference.

Problem three: the invoice is in dollars — your bank statement disagrees

Rae's brass supplier invoices in euros. Her card statement shows a dollar figure that is never quite the conversion she calculated.

Two things are happening. The first is the exchange rate itself, which moved between the day she agreed the price and the day the charge settled. The second is the foreign transaction fee — a spread her card issuer and the card network add on top of the interbank rate. Card terms vary widely: some cards charge nothing at all, others take a percentage of every foreign-currency transaction. The only way to know yours is to read the cardholder agreement.

Neither number appears on the supplier's invoice. Both are real costs of acquiring the goods.

The fix: cost your purchases from the amount that actually left your account, not the amount on the invoice. If you're recording purchases as you place them, go back and true them up when the statement posts. It is ten minutes a month and it removes an entire category of quiet error.

Problem four: what arrives is not always what you paid for

Twelve hides shipped. One has a brand scar running through the middle of the good section, and Rae can get maybe half a bag out of it.

She paid for twelve. She has eleven and a half.

Every purchase carries some receiving shrinkage — the gap between quantity invoiced and quantity you can actually turn into product. Damage in transit, short shipments, a case that got wet, a resin that partially cured, glass that arrived with three broken. For some materials it's negligible. For hides, produce, glass, and anything shipped a long way, it is not.

The honest way to handle it is to divide landed cost by usable quantity, not invoiced quantity. Rae's twelve hides at a landed $686 aren't $57.17 each; against 11.5 usable hides they're $59.65. That's a 4% error hiding inside a number she thought was precise.

Don't estimate this from feel. Shrinkage is easy to underestimate when you're working from memory rather than a log — so log what you actually receive against what you ordered for a few months, and let the pattern tell you the rate.

Problem five: one shipment, three products, one bill to divide up

Here's where landed cost gets genuinely fiddly, and where spreadsheets start to buckle.

Rae's brass shipment contains three items: 240 clasps, 500 rivets, and 60 buckles. The duty, the MPF, and the freight all arrived as shipment-level numbers. Her pricing needs unit-level numbers. Something has to allocate the one across the other.

There are three common bases, and the choice is not arbitrary:

• Value-based allocation — each line takes a share of the shipment cost proportional to its share of the invoice value. Correct for duty (which is assessed on value), the MPF (ad valorem), and insurance.
• Weight-based allocation — each line takes a share proportional to its weight. Correct for freight, which the carrier priced on weight and volume.
• Unit-count allocation — divide evenly across pieces. Crude, but perfectly fine when everything in the carton is roughly the same size and price.

Using value-based allocation for freight is a common mistake, and it has a predictable failure mode: your expensive, light items absorb freight they didn't cause, and your cheap, heavy items look cheaper than they are. If you make one product from brass wire and another from lead-weighted bases, this error will point your whole catalog in the wrong direction.

You don't need to be exact. You need to be consistent and roughly right, and you need to know which basis you chose.

A worked example

Rae's brass shipment, all in. Every figure below is illustrative — a constructed shipment, not a benchmark. This particular order carried no separate insurance or handling charge, so you won't see line items for either:

The order is 25.7% more expensive than the invoice. Not a rounding error. Not "a bit for shipping."

Now allocate. The clasps are $600 of the $1,180 invoice value (50.8%) and, being the heaviest item, 62% of the shipment weight.

• Value-driven costs — duty, MPF, foreign transaction, and disbursement ($156.78) — allocate at 50.8%: $79.64
• Weight-driven cost — freight ($146.00) — allocates at 62%: $90.52
• Clasp landed cost: $600.00 + $79.64 + $90.52 = $770.16

Now apply Problem four. Three of the 240 clasps arrive deformed, leaving 237 usable — so the landed cost per usable clasp is $770.16 ÷ 237 = $3.25.

Two clasps go into each bag. At the invoice price, that's $5.00 of clasp per bag. At landed cost, on usable quantity, it's $6.50.

A dollar-fifty. On a bag Rae sells at $180, that's not a crisis. But she makes four other products from the same shipment, she reorders five times a year, and she set her wholesale price at a 50% discount off retail — which means every error in her cost base gets doubled before it reaches her margin. The gap compounds in exactly the place she can least afford it.

The landed-cost glossary

The vocabulary is half the battle. These are the terms you'll meet on invoices, in customs paperwork, and in any conversation with a bookkeeper about inventory.

• Landed cost — the total cost of getting purchased goods onto your shelf and ready to use: purchase price plus all acquisition costs.
• Landed unit cost — landed cost divided by the usable quantity received. The number that belongs in your bill of materials.
• Freight-in — inbound shipping, supplier to you. Part of the cost of the goods.
• Freight-out — outbound shipping, you to customer. A selling expense, not part of the goods.
• De minimis — the administrative exemption at 19 U.S.C. 1321(a)(2)(C), often called "Section 321," that formerly let shipments worth $800 or less enter duty-free. Suspended for commercial imports; see Problem two.
• Duty — the tax assessed on imported goods, at a rate set by the item's tariff classification.
• HTS / HTSUS — the Harmonized Tariff Schedule of the United States, the ten-digit classification system that determines your duty rate. Classification is the importer's responsibility.
• Merchandise processing fee (MPF) — a CBP user fee charged on entries, ad valorem with a floor and a ceiling on formal entries.
• Formal entry — the full customs entry process, generally required above $2,500 and for goods subject to additional requirements or duties.
• Informal entry — a lighter, cheaper entry process available for qualifying shipments at or below $2,500.
• Customs broker — a licensed agent who files entries on your behalf. Optional for simple shipments, invaluable for complicated ones.
• Disbursement fee (also advancement fee, duty handling fee) — what a carrier charges for paying your duty to CBP up front.
• Receiving shrinkage — the gap between quantity invoiced and quantity usable, from damage, short shipment, or defect.
• Allocation basis — the rule (value, weight, or unit count) you use to spread a shipment-level cost across the individual items in the shipment.
• Incoterms — the standardized three-letter trade terms (EXW, FOB, DDP, and others) that define exactly where the seller's responsibility for cost and risk ends and yours begins. Two suppliers quoting "the same price" on different Incoterms are not quoting the same price.

Where this actually shows up in your books

Landed cost is not a separate ledger. It lands in three places:

1. Inventory valuation. The value of what's on your shelf should reflect what you paid to put it there, not the invoice subtotal.
2. Cost of goods sold. When the item sells, the landed cost flows through COGS. This is the Publication 334, Line 39 treatment above.
3. Your prices. If your material costs are understated, every markup you apply is applied to the wrong base, and your margin is a smaller number than your spreadsheet says.

The third one is the reason to bother. The first two are the reason your accountant will thank you.

This is also the point where the spreadsheet method starts to creak. Landed cost is not hard math, but it's recurring math — every purchase, every allocation, every price change rippling back through every recipe that uses the material. Ardent Seller was built for exactly that ripple: attach freight and fees to a purchase, and the landed unit cost flows automatically into every recipe, product, and price tier that depends on it, so a duty increase on brass shows up as a margin change on bags without anyone re-typing a formula. You can see how the costing side works or start a free account and cost your next purchase order properly.

In this illustrative example, Rae's fix was not a new supplier. She kept the tannery and the foundry, moved her freight and fee lines onto the purchases themselves, started counting usable units instead of invoiced ones, and raised her wholesale sheet by the difference. Same materials, same bags — she had simply been selling them at a price built on the wrong number.

Try it on your last three invoices

Go pull your last three supply invoices — the ones you already recorded — and add up everything that wasn't the goods themselves. Freight, duty, fees, currency, the units that arrived broken. Divide by what you actually received. If the number is more than a few percent above what's in your pricing sheet, you now know exactly how much of your margin has been leaking, and where.
