High tariffs in many sectors continue to hinder access to the Thai market for many U.S. products. The highest ad valorem tariff rates apply to imports competing with locally produced goods, including automobiles and automotive parts, motorcycles, beef, pork, poultry, tea, tobacco, flowers, beer and spirits, and textiles and apparel. Wine imports are subject to a 54 percent tariff and six different taxes; taken together, the effective duty and tax burden is nearly 400 percent. Industry has raised concerns about the import tariffs on wine and disparate ad valorem taxes that appear to favor domestic white liquor.
