U.S. imports of mixing & kneading machines for mineral substances (other) (HS 847439) totaled $3.3M in April 2026, traded with 21 countries.

Last updated: April 2026 data

Italy leads US imports of mixing and kneading machines for earth, stone, ore, and other solid mineral substances not covered by the concrete-mixer or bitumen-mixer subheadings — a residual category that includes equipment for ceramic body preparation, refractory material blending, and specialty mineral compound processing. Germany and Finland are also significant sources, consistent with their industrial ceramics and mining-equipment sectors. The single US tariff line (8474390000) consolidates all such machines, so classification disputes most often arise at the boundary with 8474.31 (concrete mixers) and 8474.32 (bitumen mixers), where the specific mineral substrate and end-use application are the determining factors.

Frequently Asked Questions

What types of equipment are typically classified under 8474.39 rather than 8474.31 or 8474.32?

Heading 8474.39 captures mixing and kneading machines whose mineral substrate is neither concrete/mortar nor bitumen-aggregate blends. Common examples include pug mills for ceramic body preparation, muller mixers for refractory materials, and kneaders for mineral-filled rubber or plastic compounds where the mineral substance is the primary ingredient. The specific material being processed — not the mechanical action — is the primary classification criterion.

Is there Section 301 exposure for mineral mixing machines imported from China under this heading?

Goods of Chinese origin classified under 8474.39 are generally subject to Section 301 tariffs. Italy, Germany, and Finland — the leading suppliers — are not subject to Section 301 measures, making European sourcing advantageous from a duty-cost perspective. Importers should verify the current Section 301 list status and any applicable exclusions with a licensed customs broker before finalizing sourcing decisions.
