Answer:
Foreign firms to make expensive modifications to their products
Step-by-step explanation:
Tariffs and non-tariff barriers are established by the countries to improve the quality of goods and services and to gain some revenue from the exports. The Hasalot is a small town that has a policy of protectionist which means the foreign firms must make an expensive modification to their products before they can export them to Nevada. Non-tariff barriers include quotas, quality, sanctions etc.
