U.S. imports of nonelectric industrial or laboratory furnaces, ovens & incinerators (nesoi) (HS 841780) totaled $8.7M in June 2026, traded with 28 countries.
Importers of Nonelectric Industrial or Laboratory Furnaces, Ovens & Incinerators (NESOI) paid $265K in duties in June 2026 — an effective duty rate of 3.9% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Nonelectric Industrial or Laboratory Furnaces, Ovens & Incinerators (NESOI) imports of $8.7M in June 2026 ran 39% above the year-to-date monthly average of $6.3M.
Nonelectric industrial furnaces, ovens, and incinerators not covered by more specific headings — including ceramic kilns, glass-melting furnaces, and waste incinerators — enter under a single tariff line (8417800000). Germany leads US imports under this heading, reflecting its strength in high-temperature process engineering, followed by Canada and China. The residual 'NESOI' scope means classification disputes are common: importers must confirm the article is not more specifically provided for under headings 841710 (ore/metal treatment), 841720 (bakery), or electric furnace headings in 8514. Detailed technical specifications identifying fuel type, operating temperature, and intended industrial process are essential supporting documents.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Nonelectric incinerators for industrial or laboratory use are explicitly included in heading 841780 and enter under 8417800000. Electric incinerators would fall under heading 8514. Importers should also check whether any environmental permits or EPA compliance documentation is required for the specific incinerator type prior to entry.
The distinction turns on operating temperature and primary function. Furnaces and ovens under 841780 are designed for high-temperature thermal processing (firing, sintering, incineration), while dryers under 8419 remove moisture at lower temperatures. CBP looks to the equipment's principal design purpose and operating parameters; manufacturer technical documentation is critical for borderline cases.
