HS code for Glass diffuser: 9405.91
Lamps and light fittings, parts thereof, of glass.
Classification of glass diffuser under HS 9405.91
The classification of a glass diffuser under HS code 9405.91 is determined by its functional role as a component of a lighting system. According to the General Rules of Interpretation (GRI) 1 and 6, products are classified based on the terms of the headings and any relative section or chapter notes. Heading 9405 covers lamps and lighting fittings, and sub-heading 9405.91 specifically identifies parts of these items that are made of glass. A glass diffuser is an essential part designed to scatter or soften light emitted from a bulb, preventing direct glare and ensuring uniform illumination. Because the item is an identifiable part of a lamp and is composed of glass, it is excluded from general glassware headings. The material composition is the primary sub-classification factor here, distinguishing it from plastic or metal parts which would fall under different subheadings within 9405.

Codes often confused with 9405.91
Common mistake. Glass diffusers are frequently misclassified under HS code 7013, which covers glassware used for table, kitchen, toilet, or office purposes. However, because the diffuser is a dedicated part of a lighting fixture, Chapter 94 takes precedence over Chapter 70. Another common error is using HS code 7020, which is a residual category for other articles of glass. If the glass item is clearly recognizable as a part of a lamp, 9405.91 is the legally correct designation.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
