Importers of Parts for Lamps, Lighting Fittings, Illuminated Signs & Nameplates, N.E.S. — Other Materials paid $6.9M in duties in April 2026 — an effective duty rate of 27% on $25.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataMetal stampings, ceramic lamp bases, brass fittings, and other non-glass, non-plastic components for luminaires and illuminated signs fall into this residual material category, which captures the broadest range of lamp-part substrates. Brass and die-cast zinc components are particularly common in decorative and architectural lighting, and their origin and material content can affect both tariff classification and any applicable trade-remedy exposure. Importers dealing in mixed-material assemblies should confirm that no single material dominates before defaulting to this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
When a die-cast zinc base is specifically designed and shaped for use as a lamp component — with a socket mount, cord channel, or other lamp-specific feature — it is generally classified as a lamp part rather than as a general base-metal article. A generic zinc casting without lamp-specific features would more likely classify under the relevant base-metal heading.
The three parts headings (81391, 81392, 81399) are differentiated solely by the constituent material of the part. Glass parts go to 81391, plastics parts to 81392, and everything else — metals, ceramics, wood, textiles — to 81399. When a part is composed of multiple materials, the essential-character rule determines which heading applies.
