HS code for Glass rods: 7002.20
Glass, unworked, in rods.
Classification of glass rods under HS 7002.20
Glass rods are classified under HS code 7002.20, which covers unworked glass in the form of rods. These are solid, usually cylindrical, lengths of glass. The classification is part of heading 7002, which also includes glass in balls and tubes. To fall under 7002.20, the rods must be "unworked," meaning they have not been ground, polished, or shaped into a specific finished article. They are essentially raw materials for further manufacturing. The manufacturing process usually involves drawing the molten glass through a die. These rods are used in various industries, including the production of laboratory glassware, lighting components, and artistic glasswork (lampworking). The material composition can vary, including soda-lime glass, borosilicate glass, or lead glass, but as long as they remain in the form of unworked rods, they stay within this subheading. The rods must be solid throughout; any hollow center would reclassify the item as a tube. The length of the rod does not typically affect the classification, provided it retains its uniform cross-section.

Codes often confused with 7002.20
Common mistake. The most common misclassification occurs between glass rods (7002.20) and glass tubes (7002.31, 7002.32, or 7002.39). The defining difference is that rods are solid, while tubes are hollow. Another frequent error is classifying worked glass rods—those that have been cut to precise lengths with finished ends or polished surfaces—under heading 7017 (laboratory glassware) or 7020 (other glass articles). Additionally, glass fibers in the form of rovings or yarns are classified under heading 7019 and should not be confused with solid glass rods.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
