About This Section
Section XIII covers manufactured articles of stone, plaster, cement (Chapter 68), ceramic products (Chapter 69), and glass and glassware (Chapter 70). Products range from building stone and cement tiles to sanitary ceramic fixtures, laboratory glassware, and art glass. Duty rates are generally moderate (3-10%), with many construction materials qualifying for FTA preferences. Anti-dumping duties apply to certain ceramic and glass products from China. Importers of asbestos-containing products (Chapter 68) face strict EPA regulation, and most asbestos products are effectively banned from US import.
