Last updated: April 2026 dataBlow-molding machines — used to form hollow plastic articles such as bottles, containers, and automotive ducts — are consolidated into a single US tariff line, 8477300000, with no further subdivision by process type or output size. Germany, Italy, and Austria together account for the leading share of US imports, reflecting the concentration of high-output stretch-blow and extrusion-blow equipment manufacturing in Central Europe. Importers should distinguish blow-molding machines from injection-molding or thermoforming equipment at the design level, as the forming process determines heading classification within Chapter 84.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Combination injection-blow machines present a classification challenge because they perform functions covered by two different subheadings. The principal function test under GRI 3(c) or the specific machine design may determine the correct heading. Consulting a licensed customs broker and, if necessary, seeking a CBP binding ruling is advisable before entry.
Under the current US schedule, both stretch-blow and extrusion-blow machines for plastics fall within 8477300000, as there is no further subdivision by blow-molding method. However, importers should confirm this with a customs broker, as technical distinctions could affect classification if CBP interprets the process differently.
