Machinery is the HTS Chapter 84 sector
Industrial machinery — NAICS 333 (Machinery Manufacturing) — concentrates almost entirely under HTS Chapter 84 (nuclear reactors, boilers, machinery, and mechanical appliances). The chapter is the broadest single HTS chapter by trade value, covering everything from agricultural and construction equipment through industrial machinery, material-handling systems, HVAC equipment, and the broader class of mechanical appliances used in manufacturing and infrastructure. The chapter structure organises subheadings by function rather than by industry served, which means a single industry hub like this one draws on dozens of distinct subheadings across the chapter.
The seven primary product categories tracked here cover construction equipment (excavators, loaders, cranes), industrial machinery (presses, machine tools, packaging machinery), agricultural equipment (overlap with the agriculture hub for the equipment subset), HVAC equipment (heating, ventilation, air-conditioning systems for commercial and industrial applications), material-handling equipment (forklifts, conveyors, palletisers), mining equipment (overlap with the mining-energy hub for the equipment subset), and pumps, compressors, and engines. Each draws on distinct supplier-country profiles centred on Germany, Japan, Italy, China, and South Korea.
The MFN profile across Chapter 84 subheadings
The MFN duty profile for Chapter 84 machinery is one of the most heterogeneous in the US tariff schedule. Some subheadings — primarily computer and computing-related machinery (8471) — carry zero MFN duty under the WTO Information Technology Agreement coverage. Other subheadings — primarily certain specialty industrial machinery — carry MFN rates in the low single digits. Capital equipment categories tend to carry modest rates between zero and roughly four percent. Specialty machinery and certain consumer-adjacent subheadings can run higher. The chapter-level average is on the low end of the broader US tariff schedule, reflecting decades of multilateral liberalisation focused on capital-goods and intermediate-machinery categories. The USITC HTS Online Reference Tool is the authoritative per-subheading rate source.
The structural pattern within Chapter 84 reflects a post-WWII policy preference for low duties on capital-goods imports that support domestic manufacturing productivity. The same preference logic justified the ITA-era zero rates on computer machinery: lowering the customs cost on productivity-enhancing capital purchases was framed as economic-growth-supporting policy. Section 232 has not extended into Chapter 84 broadly, though specific machinery subheadings that contain Section 232-covered metal inputs face indirect cost-of-input pressure from the steel and aluminum actions.
Section 301 on Chinese-origin machinery
Section 301 List 1 attaches at twenty-five percent on a broad range of Chinese-origin Chapter 84 machinery subheadings. The 2018 escalation hit Chinese-origin industrial machinery, certain construction equipment categories, certain consumer-adjacent machinery (food-processing equipment, packaging machinery), and a wide swath of intermediate machinery used in manufacturing process lines. The cumulative customs cost on Chinese-origin Chapter 84 imports has driven substantial sourcing migration toward German, Japanese, Italian, and increasingly Indian alternative-origin production over the 2018 to 2025 window.
The migration has been easier in some categories than others. For commoditised construction and material-handling equipment, the German and Japanese supplier ecosystem has absorbed significant market share from Chinese alternatives. For specialty industrial machinery where Chinese manufacturers had developed capability advantages through scale — printing presses, certain textile machinery, plastic-injection moulding equipment — the Section 301 burden has been more difficult to escape, and US importers continue to pay the stacked rate on Chinese supplies because the production-capability alternative does not exist at the same price point.
European supplier concentration and the bilateral framework
German machinery manufacturers — Siemens, Bosch, Krauss Maffei, Trumpf, and dozens of mid-sized specialty producers — dominate the US import flow for many specialty industrial-machinery categories. Japanese suppliers — Komatsu, Hitachi, Mitsubishi Heavy Industries, Yaskawa — dominate the construction-equipment and industrial-automation segments. Italian suppliers concentrate in the food-processing-machinery, certain machine-tool, and certain specialty textile-machinery categories. The 2025 bilateral framework agreements established defined rate treatment for several signatory countries in machinery-specific subheadings; the agreements supplement rather than supplant the underlying MFN baseline structure for non-signatory origins.
For US machinery importers, the practical sourcing analysis weighs the bilateral-rate certainty against the per-unit cost differential and the supplier relationship lock-in associated with multi-year capital-equipment programmes. A printing-press buyer committing to a multi-million-dollar German equipment purchase is typically less sensitive to a small customs duty differential than to the after-sales support and parts-availability profile of the supplier; a high-volume buyer of commodity material-handling equipment is more sensitive to the customs cost component.
USMCA and the limited Mexican machinery flow
Mexico's machinery export profile to the US is smaller than the apparel or automotive cases despite the integrated USMCA framework. The reason is structural: complex specialty machinery requires deep engineering and component-supply capacity that Mexico is still building out, while Mexico has competitive advantages in labour-intensive assembly that fit consumer-goods and automotive-component segments better than they fit capital equipment. USMCA-qualifying Mexican machinery does enter at zero customs duty on the MFN component, and the Section 122 surcharge does not attach. The qualifying-determination rule for Chapter 84 follows the chapter-specific rule of origin which typically requires substantial transformation within the USMCA member country.
Section 122 surcharge in the machinery hub
The February 2026 Section 122 ten-percent surcharge attaches to most Chapter 84 subheadings outside the USMCA-qualifying flow and outside the bilateral-deal carve-outs. The exemption list carved out specific critical-defence-industrial-base machinery categories and certain medical-equipment subheadings but did not exempt the broader industrial and construction equipment categories. For a non-USMCA non-bilateral machinery import from Germany or Italy, the combined effective rate is the MFN baseline plus the Section 122 surcharge — typically landing in the low-to-mid teens. For a Chinese-origin machinery import, the combined rate adds Section 301 List 1 on top, producing stacked effective rates in the upper thirties.
The Section 232 product perimeter does not extend directly to Chapter 84 machinery, but the input-cost side does feel the steel and aluminum action through the cost of metal inputs used by the foreign machinery manufacturer. The effect is indirect — a German machine-tool producer absorbs higher steel input cost which gets reflected in the wholesale equipment price that the US importer pays. The customs duty side does not capture this indirect pass-through; only the invoice-value side does.
After-sales support and parts-availability in capital procurement
For machinery imports specifically, the customs duty component is only one piece of the multi-year total cost of ownership analysis that buyers conduct on capital-equipment purchases. The after-sales support infrastructure, the parts-availability lead time, and the supplier's domestic-service-presence in the US market often weigh more heavily than the customs cost differential between alternative-origin suppliers. German and Japanese suppliers have invested in extensive US-based service infrastructure across decades of capital-equipment market penetration, which is the structural reason their share has held even through the Section 301 escalation cycle. Chinese suppliers attempting to compete in higher-value machinery categories have faced the parts-availability constraint as a more binding limitation than the customs duty.
The capital-equipment procurement cycle for industrial machinery typically runs over multi-year contract commitments with embedded options for parts, service, and equipment refresh. The buyer's total-cost-of- ownership calculation includes the customs duty on the initial equipment purchase, the customs duty on replacement parts over the equipment lifecycle, the service-contract cost, and the downtime cost associated with parts-availability constraints. For complex machinery, the parts and service component can rival or exceed the initial equipment cost over a ten-to-fifteen-year operating lifecycle. The customs treatment on parts is typically the same as on the original equipment under Chapter 84 — meaning Section 301 attaches to Chinese-origin replacement parts for Chinese-origin equipment, which compounds the cost differential across the equipment lifecycle.
The aftermarket parts and re-import question
US-based machinery service providers occasionally rebuild, refurbish, or modify foreign-origin machinery and re-export the rebuilt unit, which raises the question of customs treatment on the re-export and any subsequent re-import. The standard customs framework treats substantially-rebuilt machinery as a new product under the substantial-transformation test, which can change the country of origin for customs purposes. For complex multi-year service-and-rebuild cycles, the customs determination requires careful documentation of the rebuild scope and the value added during the rebuild operation. Licensed customs brokers and trade compliance professionals typically advise on the per-rebuild determination.
How to verify a specific machinery rate
The verification path is HTS-subheading-specific: identify the relevant Chapter 84 subheading in the USITC HTS Online Reference Tool; confirm the column-one general MFN rate; check USMCA qualifying status for Mexican or Canadian origin; check Section 301 attachment for Chinese origin; check bilateral-deal rate modification for partner-country origin; layer in Section 122 unless USMCA-qualifying or exemption-listed. The USITC DataWeb tariff database cross-references the rate against actual customs collections, and the BLS QCEW industry index for NAICS 333 provides the employment and establishment baseline. For specialty subheadings, the Department of Commerce-published machinery trade compliance guidance provides industry-specific context. Capital-equipment buyers committing to multi-million-dollar machinery purchases should plan the total-cost-of-ownership analysis across the equipment lifecycle, including the customs cost on replacement parts and the service-contract components that arise over the multi-year operating period. Specialty machinery procurement teams typically maintain long-term tariff-forecast scenarios that account for plausible Section 301 list modifications, Section 122 exemption-list updates, and bilateral-deal renegotiation outcomes across the equipment lifecycle, because the operating cost trajectory depends on policy stability as much as on equipment performance.
