If a merchant appears to charge foreign transaction fees in the United States, first distinguish the merchant’s own checkout charges from a foreign transaction fee imposed by your bank or card issuer. In most card transactions, the fee commonly described as a “foreign transaction fee” is assessed under the cardholder’s account terms rather than directly by the merchant, although merchants and payment providers may separately apply currency conversion or other disclosed charges.
Most cases result in the purchase being completed and any applicable international or foreign transaction fee appearing when the transaction posts to the card account. If the merchant also uses currency conversion or another cross-border payment arrangement, the total cost may include separate charges or an exchange-rate markup in addition to the issuer’s fee.

Why this happens
International card transactions can involve several parties, making it easy to misidentify who imposed a particular charge.
Common reasons include:
- The card issuer charges a foreign transaction fee.
- The merchant is located or processed outside the cardholder’s home country.
- The transaction is processed through an international payment arrangement.
- Currency conversion is required.
- Dynamic currency conversion is selected. If dynamic currency conversion appears at checkout, the merchant or payment provider may offer to convert the purchase into the cardholder’s home currency under a separate conversion arrangement.
- The merchant or payment provider applies a separate disclosed conversion arrangement.
- The card does not include a foreign transaction fee waiver.
A merchant’s location, the transaction currency, and where the payment is processed can all differ, so paying in U.S. dollars does not by itself establish whether an issuer’s foreign transaction fee will apply.
What happens
When the card payment is submitted, transaction information passes through the merchant’s payment processor, payment network, and card issuer.
The process may include:
- Submitting the purchase for authorization.
- Identifying the merchant and transaction information.
- Determining the transaction currency.
- Processing any applicable currency conversion.
- Routing the transaction through the payment network.
- Applying the issuer’s account terms.
- Posting the final purchase amount.
- Adding an eligible foreign transaction fee.
The account may later show:
- The purchase amount.
- A converted transaction amount.
- A foreign transaction fee. If your bank charges international transaction fees, that issuer-assessed charge should be distinguished from conversion or other charges originating from the merchant or payment provider.
- Other separately assessed charges.
A charge associated with currency conversion should therefore not automatically be assumed to be the same thing as a bank-imposed foreign transaction fee.
What determines the outcome
Several factors influence whether a foreign transaction fee applies:
- Card agreement.
- Card issuer fee policy.
- Merchant and transaction processing location.
- Transaction currency.
- Payment network processing.
- Currency conversion method.
- Account benefits.
- Fee waiver provisions.
Two customers making similar purchases may therefore face different costs if they use cards with different fee structures.
What it may lead to
Common outcome:
The merchant completes the sale, and the card issuer applies any foreign transaction fee required by the cardholder’s account terms.
Possible escalation:
Currency conversion, merchant-related charges, or other international transaction costs apply in addition to the issuer’s foreign transaction fee.
Worst realistic outcome:
The customer pays substantially more than the original purchase amount because multiple valid conversion and international transaction costs apply and remain after review.
Common escalation triggers
Situations often become more complicated when:
- The merchant is processed internationally.
- The purchase is made in a foreign currency.
- Dynamic currency conversion is used.
- The cardholder believes the merchant directly imposed the issuer’s fee.
- The cardholder expected the card to have no foreign transaction fee.
- Multiple charges appear separately.
- The merchant’s displayed amount differs from the posted amount. If exchange rates differ from expectations, the difference may result from the conversion method, timing, markup, or the party responsible for converting the transaction.
- The final transaction cost is substantially higher than expected.
What this depends on
The outcome may depend on:
- Merchant payment arrangements.
- Card issuer terms.
- Payment network procedures.
- Transaction currency.
- Processing location.
- Currency conversion.
- Account benefits.
- Applicable merchant or payment-provider charges.
Who controls the process
Operational control generally rests with:
- The merchant for the sale price and merchant-imposed charges.
- The merchant’s payment processor for transaction routing.
- The payment network for network processing.
- The card issuer or bank for cardholder foreign transaction fees.
- Currency conversion providers when conversion is involved.
The merchant generally does not control a foreign transaction fee independently imposed by the customer’s card issuer. Identifying the source of the charge is therefore important before questioning or disputing it.
