SITCSection 7
U.S. imports of machines for assembling electric lamps & tubes, and for manufacturing or hot working glass (SITC 72841) totaled $5.2M in April 2026, traded with 17 countries.
Importers of Machines for Assembling Electric Lamps & Tubes, and for Manufacturing or Hot Working Glass paid $704K in duties in April 2026 — an effective duty rate of 14% on $5.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Machines for Assembling Electric Lamps & Tubes, and for Manufacturing or Hot Working Glass imports of $5.2M in April 2026 ran 11% below the year-to-date monthly average of $5.8M.
Last updated: April 2026 dataLamp-sealing machines, tube-exhaust equipment, and glass-forming machinery — including ribbon machines for bulb production and hot-glass pressing and blowing equipment — are grouped under SITC 72841, reflecting the shared glass-envelope technology that links electric lamp assembly and glassware manufacturing. The heading covers both the assembly of finished lamps and tubes in glass envelopes and the upstream hot-working of glass itself, making it relevant to both the lighting manufacturing and specialty glass industries. LED lamp assembly equipment that does not involve glass envelope sealing may fall outside this heading, so the presence of a glass-working step is a key classification criterion.

Generally, no. SITC 72841 is specifically scoped to machines assembling lamps and tubes in glass envelopes and to hot glass working. LED assembly equipment that mounts chips onto circuit boards and encapsulates them in plastic or ceramic — without a glass envelope sealing step — would more likely classify under semiconductor assembly or general electronics assembly machinery headings.
A glass bottle-forming machine involves hot working of glass and would generally fall within SITC 72841's scope for glass manufacturing machinery, rather than under packaging machinery headings. The distinction turns on whether the machine forms the glass article itself (72841) versus filling or sealing already-formed glass containers (packaging machinery).
