U.S. imports of parts for electric filament, discharge, and arc lamps (HS 853990) totaled $1.7M in April 2026, traded with 33 countries.
Importers of Parts for Electric Filament, Discharge, and Arc Lamps paid $204K in duties in April 2026 — an effective duty rate of 15% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts for Electric Filament, Discharge, and Arc Lamps imports of $1.7M in April 2026 ran 19% above the year-to-date monthly average of $1.5M.
Last updated: April 2026 dataGermany leads US imports of lamp parts — components such as lamp bases, filament assemblies, glass envelopes, and electrode subassemblies used in the manufacture or repair of filament, discharge, and arc lamps — with China, Japan, Taiwan, and Hungary also significant sources. The heading resolves to a single 10-digit line (8539900000), so classification effort focuses on the heading-level boundary: parts must be identifiable as dedicated lamp components rather than general electrical or glass parts classifiable elsewhere. Germany and Japan's prominence reflects their roles as precision component suppliers to the specialty and professional lamp manufacturing sector. Importers should be prepared to document the specific lamp type the parts are designed for, as CBP may request technical specifications to confirm classification under this heading versus Chapter 70 (glass) or Chapter 74/76 (metal components).

CBP applies the GRI and relevant chapter notes: a part must be identifiable as suitable for use solely or principally with electric lamps of headings 8539. Generic glass tubing, wire, or metal fittings that have broad industrial uses are typically classified by their material composition (e.g., Chapter 70 for glass, Chapter 74 for copper). Components such as prefabricated lamp bases, electrode assemblies, or getter assemblies designed specifically for lamp production are more readily classified here. Technical drawings, supplier specifications, and end-use declarations strengthen the classification position.
Because all qualifying lamp parts fall under one 10-digit line (8539900000), mixed shipments of parts for different lamp types — filament, discharge, and arc — do not require line-by-line separation within this heading. However, the risk lies at the heading boundary: if a shipment contains both dedicated lamp parts and general-purpose components, the general components must be separately classified under their appropriate headings. Importers should ensure commercial invoices itemize components with sufficient technical detail to support the classification of each line item.
