Slides 16-17 of week 7 highlighted examples of tariff peaks within men's and women's suits of artificial and synthetic fibers in the US tariff schedule. Your assignment is to find some more examples for the United States or another country. You may not use HS headings that appeared in the week 7 slides in your response to this question (do not use 6103, 6104, 9502, 9503, nor the codes in the Dian Zhang graphic). You may not use heading 9903, which has the trade-war tariffs. a) First, identify at least one 4-digit HS code in which there is substantial variation in the applied MFN tariff rates across the 6-digit HS codes within that 4-digit category. Second, identify at least one 6-digit HS codes in which there is substantial variation in the applied MFN tariff rates across the 8-digit HS codes within that 6-digit category. For our purpose here, there is "substantial variation" when one of the following is true: . Ad valorem tariffs: The maximum ad valorem tariff is at least 5 percentage points greater than the minimum ad valorem tariff and at least twice the minimum ad valorem tariff. . Specific tariffs: The minimum specific tariff is at least $0.04/kg and the maximum specific tariff is at least 2 times the minimum. b) For each of the HS codes, can you provide an economic rationale for the variation that you observe? c) Preferential trade agreements (PTAs) reduce tariff rates below their MFN levels. Identify a case in which the rate of duty applied to PTA partners notably varies within a 6-digit HS code. This could be variation in duties across 8-digit products or across partner countries for the same product. For example, the slide presenting HS heading 6103 reveals that Oman faces more variation within 6103.10 than other PTA partners. Suggested methodology You are welcome to study any country's tariff rates. If you choose the United States, here is a suggestion for working with the US tariff schedule: . Go to http://tariffdata. wto. org/ReportersAndProducts . aspx and select United States (2017) as Pa reporter and select all products. Download the Excel file, which will be about 17MB after unzipping it. to . Within the Excel file, look for 4-digit or 6-digit HS subheadings that have more than one tariff line (TL). . Search for those HS codes in the 2021 Harmonized Tariff Schedule to obtain the 8-digit HS code tariff rates. Look for peaks. If you would prefer to use statistical software, the entire US HTS is posted on Canvas in a 3.7MB file called 2021USHTS . csv." You could write code that identifies the peaks in these data
