The total cost of importing: why the supplier price doesn't show your real margin

Every import looks cheap on the first spreadsheet.

The supplier sends a price, someone multiplies it by the day's exchange rate, compares it with the cost in Brazil, and the math works out beautifully. This is the moment when most bad import decisions are born — not out of bad faith, but because the first number to arrive was mistaken for the real cost.

The supplier's price is the beginning of the calculation, not the end. Between the quoted price and a product ready to sell, there's a sequence of costs that, added together, determine whether the operation has margin — or whether you're importing only to discover the loss further down the road.

What really makes up the cost of an import

Import cost is not "price × exchange rate". It's a chain. In broad terms, it includes:

• Price of the goods (usually quoted FOB or EXW)
• International freight and insurance
• Import taxes (II, IPI, PIS/COFINS and ICMS)
• Customs expenses, customs broker fees, and Siscomex charges
• Stevedoring, warehousing, and handling at the port or airport
• Inland freight to your warehouse
• Currency fluctuation between closing and payment
• Internal costs: team, time, idle capital, and risk

Notice that several of these items don't appear in the supplier's quote. They emerge along the way — and each one changes the final price of the imported product.

Customs value: the base most people overlook

One point that often catches companies off guard is how taxes are calculated. They don't apply only to the price of the goods. The base is the customs value — and it's higher than the supplier's price.

In practice, this means that cutting the product price by 5% doesn't cut the final cost by 5%. And that more expensive freight raises not only the transport bill, but also the tax bill that follows it.

The costs that vanish from the spreadsheet

Taxes, at least, are predictable. What usually destroys margin are the costs no one remembered to include:

Warehousing and demurrage

Cargo held up by a document discrepancy, a pending license, or simple lack of planning generates daily warehousing charges and, for containers, demurrage. It's a cost that grows on its own while the problem goes unresolved.

Exchange rate

Weeks can pass between closing the purchase and actually paying for it. If the exchange rate moves in that window, what looked like a comfortable margin can evaporate. Imports carry currency exposure even when no one consciously took it on.

Rework and non-conformity

A product that arrives out of spec, without the required certification, or with incorrect documentation becomes an extra cost: re-inspection, re-shipment, fines, or inventory that can't be sold.

Total cost and cash flow are not the same thing

An operation can have a good margin and still suffocate the company. Imports concentrate the outflow at the start — supplier, freight, taxes — and the return only comes when the goods are sold, sometimes months later.

That's why total cost answers "does this import turn a profit?", while cash flow answers "can the company hold out until that profit shows up?". Both questions need to be asked. Deciding while looking at only one of them is like driving while seeing only half the road.

A bad import rarely starts out expensive. It starts out looking cheap.

How to turn this into a decision

The goal isn't to build the most complex spreadsheet in the world. It's to build the honest spreadsheet — the one that shows the total cost (the so-called landed cost) and the real margin before the order is placed. A good starting point:

1. List every cost in the chain, not just the supplier's price.
2. Calculate taxes on the customs value, not on the FOB price.
3. Include an unfavorable exchange rate scenario, not just today's rate.
4. Project the cash flow: how much goes out, when it comes back in, and how long the money stays tied up.
5. Only then compare with the domestic alternative or the current sale price.

When the total cost is clear, the decision stops being a bet and becomes an informed choice.

The main point

The supplier's price is information. The total cost is the decision. They're different things — and confusing them costs margin.

Before closing an import, the question isn't "how much does the product cost?". It's "how much does it cost to make this product available to sell, and what's left after that?".
