A purchase order priced in one currency, freight billed in another, and duty assessed on a customs value converted at entry: the exchange rate moves three times inside one landed cost. This post shows where each conversion happens and how importers stop the swing landing entirely on margin.

## One shipment, three exchange rates

The catalogue price was set months ago from a forecast rate. The supplier invoice is settled on a payment date at whatever the market is doing that week. And the customs value, declared in the supplier currency, is converted for duty purposes using the rate rules of the importing country at entry. Each step is defensible on its own. Together they mean the landed cost on the spreadsheet and the landed cost in the bank account are cousins, not twins.

For a brand working on ten points of margin, a five percent currency move between order and entry is not a finance footnote. It is half the profit on the line, arriving silently, spread across invoices nobody lines up side by side.

## Where the swing hides in the accounts

Freight is often billed in dollars while goods are bought in the supplier currency, so a swing changes the ratio between product cost and freight cost per unit even when both invoices are exactly as quoted. Duty then applies to a converted value that neither the buyer nor the supplier chose.

The hiding place is the average. Finance teams true up currency differences in a monthly overhead line, which keeps the P and L honest and the product costing blind. The SKU that lost money to the swing keeps its old price, because no report ever attached the loss to it. Attach it. Landed cost by shipment, at the rates actually paid, is the only version a pricing decision should ever see.

## Bands, clauses, and honest hedges

Price from a band: set the retail price to work at the weak end of a realistic rate range, and treat anything better as found money rather than as the margin the business depends on. It feels conservative in a strong month. It is the reason a weak month is a disappointment instead of an emergency.

In purchase terms, agree the currency of the invoice and a movement clause: beyond an agreed percentage swing between order and shipment, the parties share or renegotiate. Suppliers accept these clauses more readily than buyers expect, because the clause protects them on the swings that run the other way.

Formal hedging has its place once volumes justify it, and its place is after the bands and clauses, not before. A forward contract on top of sloppy product costing just locks in the sloppiness at a fixed rate.

## The per shipment review that catches it

Once a month, pick the five largest shipments and rebuild their landed cost from the paid invoices at the paid rates, next to the cost the pricing was based on. The variance, named by shipment and by cause, is the whole control. Teams that run it stop arguing about whether currency matters to pricing, because they have watched it matter, in numbers with their own order references on them.

## Frequently asked questions

## Which exchange rate does customs use for duty?

The importing country converts the declared customs value using its official rate rules at the time of entry, not the rate on the purchase order or the payment. Importers do not choose this rate, which is why entry timing can change the duty on identical goods.

## Should a brand price products in the supplier currency?

Pricing to customers stays in the customer currency. The question is internal: model the margin in both currencies and set the customer price from a rate band that survives a realistic swing, instead of from the single rate on the day the spreadsheet was built.

## What is a currency movement clause in a purchase order?

An agreed term that shares or renegotiates the price if the exchange rate moves beyond a set percentage between order and shipment or payment. It turns a unilateral surprise into a shared, bounded risk that both sides priced in advance.

## Is hedging worth it for a small importer?

Only after product costing uses actual paid rates and prices are set from a band. Hedging smooths cash flow on known volumes; it cannot repair margins that were wrong at the rate originally assumed.
