Under U.S. anti-boycott regulations, when can a U.S. person refuse to do business with parties in a boycotted country?

Under U.S. anti-boycott regulations, a U.S. person can refuse to do business with parties in a boycotted country primarily in response to a customer's request. These regulations are designed to discourage U.S. businesses from participating in international boycotts that the U.S. government does not endorse, which often occur in the context of trade relations with countries such as Israel and certain Arab nations.

When a customer explicitly requests that a company refuse to do business with, or discriminate against, a particular country or entity, the U.S. entity is allowed to comply. However, this compliance must be carefully assessed because it could still lead to significant legal implications under the anti-boycott rules. Thus, the guidelines encourage businesses to consider their customer's requests while also adhering to U.S. laws that promote non-discriminatory practices in international trade.

The other potential answers do not accurately reflect the specific conditions under which U.S. persons can refuse business dealings with boycotted entities. For example, refusing business at any time without a customer's request does not align with the structured nature of the regulations. Similarly, stating that refusals depend solely on the type of transaction does not capture the essential factor of a customer's request that triggers this option under the law
