U.S. imports of machines for manufacturing or hot working glass or glassware (other) (HS 847529) totaled $3.1M in August 2026, imported from 19 countries.
Importers of Machines for Manufacturing or Hot Working Glass or Glassware (Other) paid $862K in duties in August 2026, an effective tariff rate of 27.80% of the $3.1M imported — duty actually collected as a share of that value, not the published tariff schedule. Machines for Manufacturing or Hot Working Glass or Glassware (Other) imports of $3.1M in August 2026 ran 42% below the year-to-date monthly average of $5.3M.
Last updated: August 2026 dataHot-working glass machinery — including forming presses, blowing machines, and tempering lines used in container, flat-glass, and specialty glassware production — falls here when not covered by the optical fiber or lamp-assembly subheadings. Notably, the single 10-digit line 8475290000 has been updated to also capture additive manufacturing machines for plaster, cement, and ceramic products, reflecting a reclassification that importers of 3D printing equipment for construction materials should be aware of. Italy and France are the leading sources, consistent with European dominance in both traditional glassforming and advanced ceramic processing equipment.

The current tariff schedule has placed additive manufacturing machines for plaster, cement, and ceramic products within 8475290000, which may seem counterintuitive given the heading's glass-working origin. This reflects a deliberate HTS reclassification. Importers of 3D printing or binder-jetting equipment for construction materials should verify their classification against this line and consult a customs broker if the product's scope is ambiguous.
Combination machines are generally classified by their principal function. If the primary operation is hot working (forming, blowing, pressing), 8475290000 is the likely heading. Cold-working operations such as cutting, grinding, or polishing glass may instead fall under heading 8464. A CBP binding ruling is advisable for integrated lines that perform both hot and cold operations.
