Electrical equipment is the heavy-power side of HTS Chapter 85
Electrical equipment manufacturing — NAICS 335 (Electrical Equipment, Appliance, and Component Manufacturing) — covers the heavy-power and infrastructure end of HTS Chapter 85. The structural distinction from NAICS 334 electronics is that this hub focuses on power-generation, power-distribution, and consumer-appliance categories rather than on computing, consumer electronics, or semiconductor product categories. Solar panels, transformers, switchgear, large kitchen appliances, electric water heaters, and electrical wiring materials fall under NAICS 335 even though they share Chapter 85 of the HTS with the broader electronics universe.
The six primary product categories tracked in this hub cover solar panels and components (HS heading 8541), power generation equipment (generators, alternators, large electrical machinery), kitchen appliances (refrigerators, ranges, dishwashers, washers, dryers), LED lighting equipment (overlap with electronics for specialty lighting; here we focus on commercial and infrastructure lighting), electrical wiring and conduit, and electric motors and components. Each draws on distinct supplier-country profiles with China, Mexico, South Korea, and Germany among the leading origins for different subcategories.
Solar panels and the Section 201 trade-remedy stack
Solar panels and photovoltaic modules occupy a distinctive position in this hub because they have been the subject of multiple stacked trade remedies that operate independently of the general Section 122, Section 232, and Section 301 framework. The Section 201 safeguard action on imported solar cells and modules, originally proclaimed in 2018 and extended through subsequent reviews, applies a defined duty rate on imports above a quota threshold. The country-specific anti-circumvention determinations issued through the 2022 to 2024 cycle further extended the Section 201 duty to certain Southeast Asian assembly operations that had been receiving Chinese-origin solar cells for module assembly. For per-shipment verification, the Federal Register publishes the operative Section 201 rate alongside any country-specific modifications.
Section 301 List 1 attaches separately to Chinese-origin solar cells and modules at twenty-five percent. The combined Section 201 plus Section 301 plus MFN stack on a Chinese-origin solar module makes Chinese-direct supply commercially uneconomic for the US market in most circumstances. The sourcing migration has been toward Vietnamese, Cambodian, Malaysian, Thai, and increasingly US-domestic solar manufacturing, with the anti-circumvention determinations periodically reshaping which Asian origins remain commercially viable. The Inflation Reduction Act tax-credit framework on solar installations adds a separate consumer-side incentive layer that varies by component-origin and domestic-content thresholds.
The kitchen-appliance segment and Section 232 metals exposure
Large kitchen appliances — refrigerators, freezers, ranges, wall ovens, dishwashers, clothes washers, clothes dryers — carry MFN duties under HTS Chapter 84 (for refrigerators and freezers under 8418) and Chapter 85 (for kitchen small appliances and certain ranges). The MFN rates run between zero and roughly two percent for most appliance categories, which keeps the customs duty component modest relative to the appliance retail price. The structural cost pressure on imported appliances comes from the Section 232 steel and aluminum exposure that the foreign appliance manufacturer absorbs as a metal-input cost, not from a direct Section 232 finished-appliance duty.
Section 301 List 1 attaches to Chinese-origin appliances at twenty-five percent, which has driven sourcing migration toward South Korean (LG, Samsung) and Mexican (Whirlpool, Electrolux assembly) production over the 2018 to 2025 window. Korean-origin appliances enter under the bilateral framework rate where applicable; Mexican-origin USMCA- qualifying appliances enter at zero MFN duty plus zero Section 122. The pricing dynamic in US appliance retail reflects the customs cost differential across origins.
Power-generation and transformer category
Power-generation equipment — large generators, alternators, transformers, switchgear, distribution panels — falls primarily under HTS Chapter 85 subheadings. The MFN duty profile here is generally modest, between zero and a few percent depending on capacity rating and configuration. The category is heavily dominated by European suppliers (Siemens, ABB) and increasingly by Chinese suppliers in the lower-cost commodity-transformer segment. Section 301 List 1 attaches to Chinese-origin transformers and certain generator subheadings; the cumulative customs cost has driven sourcing migration toward Korean, Mexican, and Indian alternative-origin production for commodity-grade equipment, while European supply remains dominant in specialty high-voltage and large-rating equipment.
Grid-scale electrical infrastructure procurement — utility-scale transformers, switchgear stations, substation equipment — operates on multi-year capital- equipment programmes where the customs cost differential is rarely the binding sourcing constraint. After-sales support, parts-availability, and grid-interconnection compatibility tend to dominate the supplier-selection analysis for these larger procurements. The USITC HTS Online Reference Tool provides the per-subheading authoritative rate for the commercial-determination side of the procurement.
Electric motors and the supply-chain integration
Electric motors and motor components under HTS Chapter 85 subheadings carry generally modest MFN duties between zero and roughly six percent depending on rating and configuration. The supplier-country distribution is broad, with China, Japan, Germany, South Korea, and Mexico leading the import flow across different motor categories. Industrial-grade motors used in HVAC, pumps, compressors, and material-handling equipment are typically purchased as components within finished machinery rather than as standalone imports, which means the Section 301 exposure on Chinese-origin motors propagates through the broader machinery supply chain.
LED lighting and the consumer-product overlap
LED lighting equipment occupies an overlap zone between this hub and the electronics hub. The commercial, infrastructure, and specialty-lighting categories that fall under NAICS 335 emphasis are covered here; the consumer-electronics-adjacent LED categories sit more naturally in the electronics hub. The Section 301 List 1 twenty-five-percent rate attaches to Chinese-origin LED lighting subheadings, and the cumulative customs cost has driven sourcing migration toward Mexican, Vietnamese, and Indian alternative-origin LED supply. Germany retains a presence in specialty commercial-grade lighting. The MFN baseline for LED lighting runs in the low single digits for most commercial categories.
Section 122 surcharge across electrical equipment
The February 2026 Section 122 ten-percent surcharge attaches to most NAICS 335 product categories outside the USMCA-qualifying flow and outside the bilateral-deal carve-outs. The exemption list carved out specific critical-infrastructure electrical equipment categories and certain medical-grade electrical equipment but did not exempt the broader consumer-appliance, lighting, and solar segments. For non-USMCA non-bilateral electrical equipment imports, the combined effective rate is the MFN baseline plus the Section 122 surcharge. For Chinese-origin equipment, the combined rate adds Section 301 List 1 plus any applicable Section 201 solar safeguard plus any AD/CVD case rate.
Grid-tied installation compliance and inverter-standard interaction
Solar panels and grid-tied electrical infrastructure face a regulatory compliance overlay through the Federal Energy Regulatory Commission and the state-level utility-interconnection standards that operate independently of the customs duty schedule. The IEEE 1547 interconnection standard, the UL 1741 inverter certification standard, and the various state-level utility-tariff requirements together define the technical compliance threshold that grid-tied solar installations must satisfy. A solar panel that clears the customs entry at the relevant HTS rate and any applicable Section 201/301 layer must still be paired with a UL-listed inverter and a utility-interconnection approval before it can be installed on a grid-tied system. The compliance frameworks operate sequentially: customs clearance, then certified-component verification, then utility-side interconnection approval.
For commercial-scale solar developers, the cumulative compliance burden has driven consolidation toward verified-supplier ecosystems where the panel, inverter, and balance-of-system components are pre-certified together rather than sourced independently. This dynamic reduces the per-project compliance overhead but constrains sourcing flexibility. For residential rooftop solar, the installer typically absorbs the supplier-selection compliance work, and the homeowner sees the cost as an embedded line item in the installed-system price rather than as a separately invoiced customs component.
Energy-efficiency standards and the appliance import flow
Large household appliances entering the US market must satisfy the Department of Energy energy-efficiency standards that apply to refrigerators, freezers, dishwashers, clothes washers, clothes dryers, and other major appliance categories. The DOE standards are published as minimum performance requirements that any appliance sold in the US must meet regardless of country of origin. The Energy Star voluntary certification programme operates as a higher-tier recognition for appliances that exceed the minimum standards. The customs entry process at the relevant HTS Chapter 84 or 85 subheading does not enforce the DOE standards; that enforcement happens at the consumer-facing retail stage through the Federal Trade Commission and the Department of Energy compliance auditing.
How to verify a specific electrical-equipment rate
The verification path layers multiple authorities: identify the relevant Chapter 84 or Chapter 85 subheading in the USITC HTS Online Reference Tool; confirm the column-one general MFN rate; check Section 201 applicability for solar cells and modules; check Section 301 attachment for Chinese origin; check USMCA qualifying status for Mexican or Canadian origin; check bilateral-deal rate modification for partner-country origin; layer in Section 122 unless USMCA-qualifying or exemption-listed; check any AD/CVD case scope applicability. The USITC DataWeb tariff database cross-references the rate against actual customs collections, the BLS QCEW industry index for NAICS 335 provides the employment and establishment baseline, and the International Trade Commission case database is the AD/CVD-active-orders authority. For utility-scale electrical procurement and commercial solar projects, the customs determination is one input into the broader project-economics analysis that also includes IRA tax-credit eligibility, state-level renewable-energy incentives, and utility-interconnection timelines — the customs side is rarely the binding constraint on these multi-year capital programmes.
