Export policy for glass and glassware: most Chapter 70 tariff items permitted for export as Free, subject to classification definitions. Chapter 70 of ITC(HS) 2022 sets classification guidance and defines scope for glass products, excluding specific non-glass or specialised items, and clarifies that 'glass' includes fused quartz. It provides rules on when glass is considered worked, defines microscopically thin absorbent/reflecting coatings, sets compositional criteria for glass wool, and defines lead crystal for certain tariff items. The tariff schedule lists Chapter 70 items from cullet and raw glass through finished glassware and glass fibres, with export status recorded as Free.
