How to Calculate Import Duty and Landed Cost

Step 2: work out the customs value

This is where the same shipment produces different duty in different countries, and where the most expensive mistakes happen.

The practical trap: if your supplier invoices you CIF but you are importing into the US, the invoice total is not your dutiable value. You deduct the freight and insurance element to get there, provided it is separately identified and documented. As CargoTrans illustrates, filing a US entry off the CIF figure instead of the goods value inflates the duty, the sectoral lines, and the user fees simultaneously, and because the same invoice format produces the same error on every shipment, it compounds quietly across a year of imports. It is worth checking your last few entries for this specifically.

Whichever basis applies, your commercial invoice needs to show the elements separately so the value can be built correctly, and the term you traded on determines what is included in the first place, which is one of the practical consequences of choosing DDP or DAP. The CIF definition is in our glossary if you want the short version.

Step 3: add the government fees

Duty is rarely the only charge the authority collects.

In the US, most formal entries carry a Merchandise Processing Fee of 0.3464% of the customs value, subject to a minimum and a maximum per entry that are adjusted periodically, so check the current figures rather than a number from an old article. Ocean shipments also pay a Harbor Maintenance Fee of 0.125%. Air freight skips HMF entirely, which is a real consideration for high-value, low-weight goods.

In the EU and UK, the significant line is import VAT, charged at the destination country's rate on the customs value plus duty, and in many cases plus transport costs to the destination. The number looks large on the invoice, but a VAT-registered importer generally recovers it or defers it through postponed accounting, so it is a cash-flow item rather than a cost. Treating recoverable VAT as a cost in your margin model will make perfectly good products look unprofitable.

Since low-value consignments lost their duty-free treatment in both markets, small parcels now attract charges too, which is covered in our guide to the end of duty-free parcels.

Step 4: a worked example, EU and US

The same shipment, costed for both markets: goods worth 20,000, freight and insurance of 2,000, a product with a 6.5% duty rate, arriving by ocean, into the Netherlands and into the US.

Two observations worth taking away. The landed costs land close together here, but for entirely different reasons: the EU charges duty on a larger base while the US adds user fees the EU does not have, so a shift in freight cost or duty rate moves the two markets differently. And the VAT line, at nearly a quarter of the shipment value, is the biggest single number on the page while usually not being a cost at all. Getting that distinction wrong is the most common error in a first landed cost model.

‍

Step 5: build the full landed cost

Duty and fees are the part people remember. The lines they forget are the ones that decide whether a product is actually profitable: inland delivery from the port to your warehouse, port and terminal charges, storage if clearance runs long, any inspection or compliance testing your category requires, and returns handling, which on consumer ecommerce is a structural cost rather than an occasional one.

Two practical notes. Divide the total by units to get a per-unit landed cost, and price from that figure rather than from the factory quote. And do this per destination market: the same product can have different duty rates, different VAT treatment, and quite different delivery costs in two countries you sell in, which is why a single global margin assumption tends to hide one market subsidising another. Our landed cost glossary entry has the short definition, and if freight is the line you want to attack first, we covered that in reducing shipping costs as an ecommerce seller.

How to reduce your landed cost legitimately

There are real levers here, and none of them involve understating a value on an invoice.

Review your classification. Products are routinely filed under a code that fits loosely when a more accurate one carries a lower rate, and a review is often the fastest money in the whole exercise. Claim the preferences you qualify for, since trade agreements only reduce duty if you actually claim them with the right origin documentation. Look at valuation methods: in the US, first-sale-for-export valuation can base duty on the manufacturer-to-middleman price rather than what you paid the middleman, though it requires careful documentation, and the mechanics are set out well by Peacock Tariff Consulting. Consider duty drawback if you re-export goods, and duty deferral through bonded warehousing or a foreign trade zone if your cash flow is the constraint. And consolidate shipments where per-entry fees and brokerage charges, which typically run in the low hundreds per entry, are eating you on frequent small imports.

That last point is the one that has changed most. When small parcels crossed borders duty-free, shipping individual orders internationally was a perfectly reasonable model. Now every parcel attracts charges and a declaration, and consolidating into bulk imports with local fulfilment is usually cheaper per unit as well as faster to the customer.

‍

Who carries the cost, and who carries the liability

One structural point tends to get lost in the arithmetic. Whoever is named as importer of record pays the duty and answers for the declared value and classification. If your numbers are wrong in your favour, that is the party customs reassesses, with interest, and the reassessment covers historical entries rather than just the current one.

So a landed cost model is only as reliable as the import setup behind it. Brands entering a new market often discover that the model assumed an importer they do not have, or relied on a supplier's classification nobody verified. eBrands closes that gap by taking the role: our entities act as Importer of Record in each registered market, with classifications maintained per market and the customs and VAT registrations already in place, while you keep ownership of the goods. The practical benefit is that your landed cost becomes a number you can plan against rather than a number you discover on a broker's invoice. If you are modelling a new market and the duty line is a guess, our team can put real figures against your actual products.

Frequently asked questions

How do you calculate import duty?
Multiply the customs value of the goods by the duty rate for their tariff classification in the destination country. Then add any applicable user fees and import VAT to get the total charged at the border.

Is duty calculated on the shipping cost too?
It depends on the market. The EU and UK use a CIF basis, so freight and insurance to the point of entry are included. The US generally uses the transaction value of the goods, excluding international freight and insurance where they are separately identified.

What is the difference between duty and landed cost?
Duty is one charge levied by customs. Landed cost is the total cost of getting a unit into your warehouse: product, freight, insurance, duty, user fees, brokerage, and inland delivery. Price from landed cost, not from the factory price.

Is import VAT part of my cost?
Usually not. A VAT-registered business generally recovers import VAT or defers it through postponed accounting, making it a cash-flow item. Treat it separately in your model so it does not distort your margins.

Can I lower my import duty legally?
Yes, through accurate classification, claiming trade agreement preferences you qualify for, valuation methods such as first sale where applicable, duty drawback on re-exports, and deferral through bonded warehousing or a foreign trade zone. Understating value or misdeclaring goods is not among the options.
