Why staring at the duty rate never produces an answer

The rate is an input, not the answer. The same rate lands very differently depending on whether you sell wholesale or retail, ship containers or parcels, hold US inventory or not. The margin left in your hands can differ by a factor of two. So the first question is not "how many points did it go up" but "what does it cost to move this shipment from my factory door to a shelf in the United States".

I have watched a lot of factories react to a tariff change by immediately asking the buyer to share the cost, and then concluding the business is dead when the buyer says no. The problem is that they walked into that conversation without their own landed cost worked out. They could not put a number on the table, so the buyer had no reason to move.

What actually belongs in landed cost

A shipment’s landed cost has at least nine lines: ex-works cost, inland transport and export clearance, ocean or air freight, destination port charges, duty and related taxes, customs brokerage, US domestic delivery, storage plus the cash tied up in inventory, and a reserve for returns and shrinkage. Leave any of them out and the margin you calculate is fiction.

The last three are the ones most often missed. Storage bills by the day, so slow-moving stock keeps costing you. Inventory ties up your cash, and three months of it means something very different to a factory than one month does. Returns are normal in retail channels — if you do not reserve for them, the year-end numbers will not reconcile.

There is one more that never appears on a cost sheet but is entirely real: payment terms. A buyer paying at 60 or 90 days is financing their working capital with yours. Many factories treat that as an industry norm rather than a cost, and never price it in.

FOB, DDP and MSRP each answer a different question

FOB answers "what does it cost up to the port". DDP answers "what does it cost delivered to my warehouse". MSRP answers "what will this sell for on the shelf". Buyers make decisions using the last two — and most factories can only quote the first.

That is the real reason an FOB-only supplier does not make the shortlist. It is not that the price is wrong; it is that the buyer cannot make a decision with it. What they need is the chain worked backwards: retail price, their margin, the delivered cost they can carry, and only then your quote.

Put all three numbers on the table and you stop being a supplier and start being someone the buyer can do the maths with. That change in standing is worth far more than shaving two points off your price.

How to work backwards from the shelf price

Calculate right to left, not left to right. Set the retail price, subtract the retailer’s required margin to get the delivered cost they can accept, then subtract duty, clearance, freight and storage. What remains is your ceiling. Your ex-works cost has to sit under it with room left to negotiate.

Retail margin expectations vary enormously by channel — mass retail, specialty and marketplaces each run on different logic. The same product in the wrong channel has its ceiling set against it before you start, and no amount of effort downstream recovers that.

What you end up with is a specific number: how much room this product has left in this channel. That number is what belongs in the meeting, in the negotiation, and in the decision about whether to keep investing.

Should you ask the buyer to share the increase, or absorb it

Start with how expensive you are to replace. If switching means re-sampling, re-auditing your factory and re-scheduling production, you have room. If they have three suppliers ready to step in, that negotiation was lost before you opened your mouth.

The way to ask is not "tariffs went up, please pay more". It is to arrive with the landed cost sheet: here are the lines that increased, here is what we have already absorbed, here is what remains, and here is what happens if nothing changes. The person with the sheet and the person without it get very different answers.

Also accept a possible outcome: that this customer, this spec or this channel should not continue. Cutting a loss is not failure. Moving the money and the capacity to where there is still room is what cutting a loss means.

The savings that are actually liabilities

Routing goods through a third country to change the origin label is the one I would tell anyone to stay away from. Responsibility for the origin declaration lands on you and on your customer, and if it is ever unwound you lose more than the shipment — you lose the customer and the channel.

Undervaluing to reduce duty transfers the same risk to your buyer. Serious retailers have compliance teams who check, and being removed from a vendor list is a record that travels between companies.

Save where you can say it out loud: redesigned specs, reduced packaging volume, containers instead of LCL, consolidating SKUs into one shipment, scheduling production to avoid air freight. Every one of those can be explained to a buyer, and explaining it makes them trust you more.

Frequently asked

Q1

Is landed cost the same as a DDP price?

No. DDP is the price you quote. Landed cost is what the shipment actually costs you. DDP minus landed cost is your margin. Factories that conflate the two end up quoting a price that looks workable and is not.
Q2

Should duty be built into the FOB price or shown separately?

Separately. FOB is defined as cost to the port of shipment; folding duty into it makes your quote unreadable and removes flexibility later. Give FOB and DDP together, and be able to explain every line in between.
Q3

How do I price in payment terms?

Multiply your cost of capital by the number of days and convert it to a per-unit figure, then add it to landed cost. A customer on 90-day terms and one paying on shipment are not the same price, and the quote should say so.
Q4

If the numbers show no margin, should I drop the customer?

First work out whether it is the customer, the channel or the spec that has no margin. A different pack size, a different channel, or volume that spreads the fixed costs can all rescue it. If none of them do, exit — but exit with a sequence, not by burning the relationship.
