International shipping cost is not the same as landed cost. Import duties, taxes, brokerage, processing and carrier disbursement fees can materially increase the amount paid before inventory reaches the warehouse.
Separate the cost layers
A useful landed-cost model separates product cost, international freight, insurance, duties, taxes, customs/brokerage charges, carrier processing or disbursement fees and final-mile delivery. Keeping these components separate makes supplier and carrier comparisons more accurate.
Disbursement fees are not duties
When a carrier advances duties or taxes to customs on the importer’s behalf, it may charge a disbursement or advancement fee for that service. UPS’s U.S. rates page currently states that its Disbursement Fee was updated effective September 7, 2026 to 2.5% of duties/taxes paid or processed by UPS, with a stated minimum fee. Carrier amounts and rules can change, so use the current rate guide for operational decisions.
Allocate import cost to products
For a mixed shipment, choose a consistent allocation basis such as customs value, quantity, weight or volume. Use the Freight Cost Allocation Calculator to distribute shipment-level costs, then use the Freight Cost Per Unit Calculator to understand margin impact.
Incoterms affect who initially pays
DDP, DAP, FOB and CIF allocate transport and import responsibilities differently. Read DDP vs DAP and FOB vs CIF vs DDP before comparing supplier quotes.
Use current customs and carrier data
Duty treatment depends on classification, origin, destination and current customs rules. Do not hard-code one duty percentage across products. For current carrier processing fees, review UPS rates and surcharge updates, and use the applicable customs authority for duty and tax rules.
The goal is a repeatable landed-cost model that can be updated when rates or customs rules change, not a one-time estimate hidden inside a spreadsheet.
Build landed cost in separate layers
| Layer | Examples | Data source |
|---|---|---|
| Product | Unit price, tooling/amortized product cost | Supplier invoice |
| International transport | Ocean/air freight, insurance | Forwarder/carrier quote |
| Import | Duties, taxes, brokerage, processing | Customs authority/broker |
| Carrier advancement | Disbursement/advancement fee | Carrier rate guide |
| Destination logistics | Handling, drayage, final delivery | Forwarder/carrier invoice |
Keeping each line separate makes the model easier to audit when one component changes and prevents duties or carrier fees from being confused with the freight rate itself.
Worked landed-cost example
Assume 1,000 units cost $10 each at the supplier. International freight and insurance total $2,500, destination/brokerage charges are $600, and duties/taxes plus applicable processing add $1,900. The total cost before domestic fulfillment is $15,000, or $15 per unit. If one of those charges was already included in the supplier’s commercial term, adding it again would overstate landed cost.
Use Incoterms to understand who initially pays—not what the cost disappears
FOB, CIF, DAP and DDP change responsibility allocation, but the commercial cost ultimately still appears somewhere in the transaction. Normalize supplier quotes to the same destination point before judging which offer is cheaper.
For that comparison, read FOB vs CIF vs DDP and DDP vs DAP.
Frequently asked questions
Are disbursement fees the same as customs duty?
No. Duty/tax is an import charge imposed under applicable customs rules. A disbursement or advancement fee is a service charge a carrier may impose for advancing or processing those amounts.
Should I estimate one duty percentage for every product?
No. Duty treatment depends on classification, origin, destination and current rules. Use the applicable customs authority or a qualified customs professional for product-specific treatment.
What should I allocate by customs value versus freight volume?
Different cost categories can justify different allocation bases. Document the rule used for each layer and keep it consistent.
How often should landed-cost models be refreshed?
Refresh them when freight rates, supplier terms, customs treatment or carrier/broker fees change materially, and reconcile estimates to actual invoices after import.
