Product classification
HS code for Plastic diffuser: 9405.92
Lamps and light fittings, parts thereof, of plastics.
Classification of plastic diffuser under HS 9405.92
Plastic diffusers are classified under HS code 9405.92 because they are identified as specific parts of lamps and lighting fittings. According to the General Interpretative Rules (GIR) and the Chapter 94 notes, parts of lamps that are made of plastics and are designed to be used exclusively or principally with a lighting fixture are categorized here. A diffuser's primary function is to scatter or spread light from a source to reduce glare and provide even illumination. Because this item is a dedicated component of a lighting system rather than a general-purpose plastic sheet or article, it moves out of Chapter 39 (Plastics) and into Chapter 94 (Furniture; bedding, mattresses, mattress supports, cushions and similar stuffed furnishings; lamps and lighting fittings). The classification depends on the item being recognizable as a part of a specific lamp or light fitting, often featuring specific shapes, mounting holes, or heat-resistant properties tailored for illumination equipment.

Codes often confused with 9405.92
Common mistake. Plastic diffusers are frequently misclassified under HS code 3926.90, which covers other articles of plastics not elsewhere specified. While diffusers are made of plastic, the specificity of their use in lighting fixtures mandates classification under 9405.92. Another common error is using 9405.11 or 9405.42, which are codes for complete lighting fixtures (like chandeliers or LED lamps) rather than individual parts. If the diffuser is imported as part of a complete kit, it may be classified with the fixture, but as a standalone replacement part, 9405.92 is the 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).
