Final answer:
Nuisance tariffs are non-tariff barriers that make the import process more difficult and costly, without relying on actual tariffs. They involve administrative paperwork, red tape, and other regulations that impede the smooth flow of imports.
Step-by-step explanation:
Nuisance tariffs can be defined as non-tariff barriers that nations impose on imports to make the import process more difficult and costly, without relying on actual tariffs. These barriers include administrative paperwork, red tape, and other regulations that impede the smooth flow of imports. Nuisance tariffs are different from traditional tariffs, as they do not involve direct taxes on imports. Instead, they are aimed at creating obstacles for importers, resulting in added expenses and delays.
