Many importers price products off the invoice cost alone, then get surprised when duty, freight, and fees eat into margin they thought they had. Landed cost is the real number — what a product actually costs to get to your warehouse, ready to sell — and calculating it before you place a purchase order is the only way to protect your margin.
Landed cost starts with the product’s unit price, then layers in everything it takes to get that product from the factory to your warehouse: international freight, marine insurance, customs duty, broker fees, port and terminal charges, and last-mile delivery. Leaving out any one of these components means underestimating your true cost — and overestimating your margin.
Duty rates depend on the product’s HTS classification, its country of origin, and whether any special programs or trade remedies apply. Two nearly identical products can carry very different duty rates depending on classification, and misclassifying a product doesn’t just risk a CBP penalty — it also means your landed cost calculation was wrong from the start.
Ocean freight rates move with fuel costs, capacity, and season, and accessorial fees like fuel surcharges, chassis fees, and demurrage can add up quickly if a shipment sits at port. Using last quarter’s freight number to price this quarter’s purchase order is one of the most common ways landed cost calculations go stale.
The importers who protect margin most consistently calculate landed cost before placing a purchase order, not after the shipment lands. That means pulling current freight quotes, confirming HTS classification and duty rate, and accounting for insurance and handling fees up front — then pricing the product against that real number instead of the invoice price alone.
Landed cost isn’t a single number you calculate once and reuse — it shifts with freight markets, duty rulings, and sourcing changes, which is why it’s worth recalculating for every new purchase order. Our landed cost calculator walks through each component so you can see your true cost before you commit to an order.
