b. Suppose you wanted to import zinc (100% pure zinc) from Mongolia. The United States has normal trade relations with Mongolia but otherwise no other trade agreements. Suppose you had a choice of how to classify your imports: either under code "26080000: Zinc ores and concentrates\" or \"79070060: Zinc, articles." Would the choice of how to classify the imports matter? If so, when would you prefer to import under code "26080000: Zinc ores and concentrates"? (5 points)
