Household Appliance Manufacturing (United States) — NAICS 3352

An investor's rollup primer. Plain language, dual-audience (public-market and private investors). This page synthesizes the two child primers and adds the ground-truth federal figures for the 4-digit level.

---

1. Overview

NAICS 3352 — Household Appliance Manufacturing — is the U.S. government's 4-digit "industry group" for the businesses that make the electric machines in an American home, from the toaster on the counter to the refrigerator against the wall. (NAICS is the North American Industry Classification System, the standard scheme federal statistical agencies use to group businesses.) [1]

The group holds two very different industries under one roof, and the whole point of reading them together is the contrast:

• NAICS 33521 — Small Electrical Appliance Manufacturing: portable countertop and personal-care electrics (toasters, blenders, air fryers, coffee makers, vacuums, hair tools). Economically this is a branded consumer-products business: U.S. firms design and market the products, but the factories are overseas. SharkNinja states plainly that it manufactures none of its own products. [4]
• NAICS 33522 — Major Household Appliance Manufacturing: the big "white goods" (refrigerators, washers, dryers, dishwashers, ranges, ovens) and — easily missed, but the source of the group's best margins — household water heaters. This is a capital-heavy, cyclical factory business tied to the U.S. housing economy and, since 2025, to tariff policy. [5]

One code, two economies: a light-asset brand game and a heavy-asset manufacturing game. An investor should not treat them as one thing. The revised child research pushes the contrast a level deeper — neither branch has a single margin profile of its own, so "household appliances" is really three or four businesses wearing one code. Sections 2 and 4 draw the contrast; Section 3 gives the group's own federal totals.

2. What's inside — the two child industries and how they differ

NAICS is a nested hierarchy: this 4-digit group splits into two 5-digit industries, each of which happens to have a single 6-digit child (33521→335210, 33522→335220), so the 5-digit and 6-digit figures are identical. The real divide is between the two branches, and it is stark. The federal shares below are computed from our ground-truth stats (Section 3) and the child primers. [4][5]

(CR4/CR8 = the combined revenue share of the largest four or eight firms; HHI = Herfindahl-Hirschman Index, the standard market-concentration score used in federal merger review; EBIT = earnings before interest and taxes. ADR = American Depositary Receipt, a U.S.-traded proxy for a foreign share.)

Where the line between the branches actually falls. Microwave and convection ovens sit on the major-appliance side, not the small — a boundary worth knowing because third-party "small appliance" retail baskets routinely include them. (The two children point at slightly different code numbers for this exclusion, but they agree on the substance: microwaves are not in 33521.) Room air conditioners, commercial fans and blowers, commercial vacuums, and commercial cooking and laundry equipment fall outside NAICS 3352 entirely — which is why listed names like Alliance Laundry and Middleby are not exposure to this group. [4][5]

How to read the split. The two branches have almost the same number of U.S. plants (~180 each) but wildly different economics. Major appliances put ~6.5× the revenue and ~5× the workers through each plant — that is the signature of heavy, fixed-cost manufacturing. Small appliances run tiny domestic footprints because the real work happens in Asian factories the U.S. brand owners don't own. So major appliances dominate the federal manufacturing statistics, while small appliances host the fastest-growing investable story (SharkNinja). Value and growth live on opposite sides of this group. [4][5]

---

3. Size of this level (federal rollup figures)

These are our ingested ground-truth U.S. Census figures for the whole of NAICS 3352. On a common 2022 Economic Census basis they reconcile with the children: plants and employment sum precisely (178 + 180 = 358; 8,857 + 47,877 = 56,734), payroll sums to within rounding ($515.2M + $2.78B = $3.29B; $132.7M + $734M ≈ $867M), and the group's $27.3B of receipts less the small child's $3.65B leaves ~$23.7B for major appliances. [4][5]

The HHI is suppressed in the federal data at this level, so we do not report or estimate it. (For reference, the small-appliance child's HHI is 1,093.7 — just inside the "moderately concentrated" band under federal merger guidelines; the major-appliance child's is itself suppressed.) Firm counts don't sum perfectly (135 + 123 = 258 across the children vs. 257 here) because a firm operating in both branches is de-duplicated at the group level; the gap is trivial. [4][5]

A note on revenue vintage — read the children's headline numbers carefully. Both children now also carry a more recent Census Annual Integrated Economic Survey reading: $3.60 billion for small appliances (2023) and $23.6 billion for major appliances (2023). [6][7] The major-appliance child now leads with its AIES figure, which is why that page reads $23.6B rather than the $23.7B implied by the 2022 Economic Census. We do not add the two AIES readings into a 2023 group total — the group's own ground-truth receipts figure is the 2022 Economic Census $27.3B, and blending vintages would manufacture a statistic. What the newer readings do tell you is directional and consistent across both branches: the domestic production base is flat, not growing. [4][5]

The undercount caveat — and it differs by branch. These figures count U.S. manufacturing shipments, not the U.S. market, and the two children distort that gap in opposite ways:

• On the small-appliance side, undercount is severe. The big American brands import essentially all their finished goods, so most of their revenue never appears as U.S. "manufacturing." One public company, SharkNinja, reported ~$6.4 billion of net sales in fiscal 2025 — roughly 1.7 times the entire $3.65B federal shipments figure for its whole child industry — because its products are assembled offshore. [3][9] Hamilton Beach, at $607 million of 2025 revenue on the same asset-light import model, tells the same story. [10] This branch also has a long tail of tiny, individually owned specialty makers that thin federal counts miss. [4]
• On the major-appliance side, undercount is low: it is almost all large corporate factories that federal statistics capture well. What the data hides here is foreign ownership — a plant in Kentucky owned by China's Haier still counts as a U.S. establishment. [5]

The ceiling estimates don't reconcile either — don't add them. Each child now carries a third-party market-size figure, and they are built on incompatible baskets. The small-appliance child cites IHA/Circana measuring $44.9 billion of 2025 U.S. retail sales for a broad "small appliances" basket (kitchen electrics $13.8B, personal care $10.9B, home comfort and water filtration $10.6B, floorcare $8.4B) — which includes imported finished goods, retail margin, accessories, and products outside the code. [11] The major-appliance child cites an industry estimate of a ~$99 billion total U.S. household-appliance market in 2024, with major appliances roughly 87% of it. [5] Those two cannot be summed or squared: the second implies a far smaller non-major slice than the first measures. Treat each as a directional ceiling for its own branch, and treat the federal $27.3B as the floor.

Net: read the $27.3B as a measure of domestic production capacity, not of the industry's economic size or the size of the U.S. appliance market, which — once imports are counted — is several times larger. [4][5]

4. Investable universe — where value concentrates across the children

Value concentrates differently depending on whether you mean federal revenue or investable opportunity, and that tension is the most useful thing at this level.

• By domestic revenue, the weight is in 33522 (major appliances) — ~87% of the group's shipments. But that branch is nearly un-investable as a full-line pure play: Whirlpool (NYSE: WHR) is the only U.S.-listed full-line pure-play in the entire industry. Everyone else who makes big appliances in America is a foreign-listed parent (Haier/GE Appliances, LG, Samsung, Electrolux, Bosch, and now Midea via an Electrolux tie-up) or a private firm (Sub-Zero/Wolf, Viking). [5]
• The second listed route on the major side is A. O. Smith (NYSE: AOS), and it is a very different animal: replacement-driven water heating sits inside this same code but earned a 24.4% North America segment margin on $2.98 billion of 2025 sales — roughly five times Whirlpool's 2025 North America EBIT margin. AOS is broader than 335220 (it also sells boilers and water treatment), so it is not a clean proxy, but it is the clearest evidence that "major appliances" is not one margin profile. [5]
• By public-market growth, the action is in 33521 (small appliances) — a much smaller slice of federal revenue, but home to SharkNinja (NYSE: SN), at roughly a $21 billion market capitalization the largest listed play in the whole group, plus small-cap value/income names Hamilton Beach (NYSE: HBB) and National Presto (NYSE: NPK), diversified consumer-products owners Newell Brands, Helen of Troy, and Spectrum Brands, and a distressed/turnaround situation in iRobot, whose revenue fell to ~$0.68 billion in 2024 as lower-priced Chinese robot-vacuum brands took share. [4]

So the group offers a natural barbell with a third leg: a cyclical, deep-value manufacturing bet (Whirlpool) and a defensive replacement-demand compounder (A. O. Smith) on the major side, and a growth/consumer-brand bet (SharkNinja) plus diversified and small-cap options on the small side. The closest thing to a foreign pure-play is Groupe SEB, which reports small domestic equipment at ~88% of its 2025 sales. [4] There is no dedicated household-appliance ETF (exchange-traded fund); broad exposure comes through consumer-discretionary and household-durables funds. Company-by-company detail lives in the two child primers. [4][5]

5. How the money works

Two different playbooks — do not use regulated-utility rate base, real-estate funds-from-operations, or mining all-in sustaining cost for either. And within each playbook, do not assume a single industry margin. [4][5]

• Small appliances (33521) — a branded-goods playbook. Owners buy finished units from third-party Asian factories, pay freight and tariffs to land them, and sell to a few big retailers. The profit lever is turning a low-cost imported unit into a branded product at a higher selling price. Gross margin is the scoreboard, and the spread is enormous: SharkNinja reported a 49.0% gross margin at the premium, innovation-led end against Hamilton Beach's 25.7% as a mature value-brand importer. [9][10] What separates them is premium pricing, differentiation, iteration speed, and direct-to-consumer reach — not manufacturing skill, which neither owns. Marketing is the real moat: SharkNinja spent 22.8% of 2025 sales on sales and marketing versus 5.8% on R&D. [9] And because tariffs land directly in cost of goods, sourcing flexibility is a profit-and-loss weapon: SharkNinja built a factory network across six countries and moved out of China, while Hamilton Beach — sourcing from ~70 suppliers, roughly two-thirds in China — took a one-time $5.3 million tariff charge in 2025 that cut full-year gross margin by 90 basis points. [4][10]
• Major appliances (33522) — a durable-goods manufacturing playbook. Owners earn on unit volume × price/mix against heavy fixed factory costs, so operating leverage cuts both ways: a plant near capacity is very profitable; the same plant at low utilization bleeds — Whirlpool's 2026 companywide guidance was cut to roughly a 4% EBIT margin, and Electrolux's North American business was still loss-making in 2025. Steel, aluminum, and plastic-resin costs plus tariffs on them swing profitability directly; Whirlpool pushed its largest price increase in over a decade (10%+, plus a further ~4%) specifically to offset tariff-driven input inflation. Mix is the other lever, which is why LG and Samsung lead U.S. dollar share while GE leads unit share. When cash tightens, the dividend is the shock absorber: Whirlpool's arc from $7.00/share in 2024, to a $3.60 annual rate in mid-2025, to suspension in 2026 — its first in 55 years — is the clearest illustration. Against all of that sits water heating, replacement-driven and far more profitable, inside the same code. [5]

Common thread: both branches are squeezed between input/tariff costs and a price-sensitive consumer, and both are hostage to a handful of retailers — though not the same ones. On the small side, Walmart was 29% and Amazon 19% of Hamilton Beach's 2025 revenue, with its five largest customers at 62%. [10] On the major side, Lowe's alone was ~15% of Whirlpool's 2025 consolidated sales and 44% of its year-end receivables. [5] Shelf and placement decisions are make-or-break across the group, and private-label pressure is constant.

6. Demand drivers

Overlapping but weighted differently across the two branches:

• Consumer spending, confidence, and interest rates — matter to both; more acutely to major appliances, which are big-ticket and often financed. On its Q1 2026 call Whirlpool said appliance demand had not been this weak since the 2008 financial crisis. [5]
• Housing turnover, new construction, and remodeling — the dominant driver for major appliances (roughly half replacement, half new-build/remodel); one industry outlook projects existing-home sales up ~14% in 2026. A lighter influence on small appliances. [5]
• Replacement cycles — small-appliance cycles run ~5–6 years; the 2020–21 pandemic purchase wave is now aging into replacement on both sides, supporting a demand floor. On the major side, emergency replacement holds up even in a bad year — but housing weakness still damages premium mix and capacity utilization, which is where the margin lives. [4][5]
• Innovation, premiumization, and social-media fads — the growth engine on the small-appliance side (air fryers, robot vacuums, premium hair tools, countertop ice makers lifting prices even when unit volumes are flat). [4]
• Channel shift — about 60% of small-appliance and housewares purchases now happen online, which rewards demonstration-friendly products, content, and reviews — and lowers entry barriers for Asian manufacturers and digitally native brands. [11]

Growth on the small side is uneven by category, not a uniform rising tide. The 2025 IHA/Circana data show kitchen electrics up 4.1% (coffee and espresso up 6.1%) and home comfort and water filtration up 1.9%, while floorcare fell 1.0% and personal care fell 0.6%. [11] Company results show the same launch-driven pattern: SharkNinja's food-preparation sales rose 31.6% and beauty and home-environment sales 45.3% in 2025 while its core air-fryer sales declined. [9] Net near-term setup: moderate, low-to-mid single-digit growth for small appliances; a cyclical trough working toward recovery for major appliances. [4][5]

---

7. Regulation

Neither branch is rate-regulated or licensed; both are governed by safety, energy, and trade rules, with trade policy now the dominant force for the whole group. The revised children sharpen — and in one place correct — the energy picture.

• Safety — the Consumer Product Safety Commission (CPSC) for hazards and recalls; de facto safety certification (Underwriters Laboratories or an equivalent Nationally Recognized Testing Laboratory) demanded by major retailers; the Federal Communications Commission (FCC) for electromagnetic interference. Recall exposure is a real, high-severity tail risk, not a formality: in May 2025 the CPSC recalled approximately 1.85 million SharkNinja pressure cookers after 106 reported burn injuries and 26 lawsuits. And from July 8, 2026, importers of most regulated consumer products must file conformity certificates electronically with Customs and Border Protection — an administrative burden that falls hardest on the import-dependent small-appliance branch. [4]
• Energy efficiency — the two branches are regulated very differently, and the "2025 rollback" framing is wrong. On the small side, Department of Energy (DOE) standards are product-specific, not industry-wide: they reach covered products such as ceiling fans, dehumidifiers, and certain air-cleaning devices (with FTC EnergyGuide labeling on ceiling fans), but most countertop appliances — blenders, toasters, coffee makers — are not federally energy-regulated at all. [4] On the major side, existing product rules remain in force with hard compliance dates: residential washers and dryers on March 1, 2028, and amended refrigerator and freezer standards on January 31, 2029 or 2030 depending on product class. DOE paused new washer/dryer standards in February 2025 and in July 2026 proposed changing the process for setting future standards, but that does not repeal the existing product rules — so manufacturers' redesign calendars have not been cleared. Separately, EPA's AIM Act imposed a global-warming-potential limit of 150 on household refrigerators and freezers made or imported from January 1, 2025, forcing sealed-system redesigns, and six states had enacted right-to-repair rules covering home appliances as of mid-2026, shifting parts and service economics. [5]
• Trade — the most consequential lever for both branches. Section 301 tariffs on Chinese goods act as a direct tax on the import-dependent small-appliance model. [4] Section 232 steel/aluminum tariffs were raised to 50% and, from June 23, 2025, extended to steel-containing household appliances, so essentially every imported appliance now faces at least a 25% U.S. tariff; the metals regime was adjusted again in 2026. The effect on major appliances is two-sided — duties on finished imports support domestic production while duties on metals and components raise domestic manufacturing costs. An earlier precedent is instructive: the 2018–2023 Section 201 washer safeguard pushed LG and Samsung to build U.S. plants before expiring in February 2023. [5]

---

8. Consolidation

Both branches are concentrated, but for different reasons.

• Major appliances (33522) are a concentrated oligopoly built by decades of dealmaking: Whirlpool bought Maytag in 2006 for ~$2.7 billion; the Department of Justice blocked Electrolux's ~$3.3 billion purchase of GE Appliances on antitrust grounds (the deal would have left ~90% of U.S. stoves and ovens with two companies); GE then sold that business to China's Haier in 2016 for $5.6 billion — which is why the top U.S. appliance maker by units is Chinese-owned today. Tariffs have set off a 2025–26 reshoring wave, though a selective one: GE Appliances committed $490 million to a new Louisville, KY washer plant (~800 jobs) inside a broader $3 billion, five-year U.S. investment across five Southern states; LG and Samsung are weighing shifting output from Mexico to their Tennessee and South Carolina plants; Electrolux is retooling Anderson, SC and in 2026 partnered with China's Midea to bring Midea into the U.S. market. Whirlpool, already 80%+ U.S.-made for its U.S. sales, estimates its tariff hit at ~5% of North American sales versus 10–15% for import-heavier competitors. The contest: whoever can most cheaply serve the U.S. market from inside the tariff wall wins share. [5]
• Small appliances (33521) show moderate domestic-factory concentration (CR4 58.6%, HHI ~1,094), but the real contest is in the brand market, which is intensely dynamic: innovation-led disruption (SharkNinja displacing legacy incumbents, and in turn iRobot losing its robot-vacuum lead to lower-priced Chinese entrants), cheap direct-from-China competition on Amazon and Temu, and continual portfolio churn as diversified owners prune non-core brands and distressed brands change hands privately — an affiliate of Centre Lane Partners bought Instant Brands' appliance business, including Instant Pot, out of bankruptcy in November 2023. Notably, no single competitor spans every category: SharkNinja names one set of rivals in floorcare and an entirely different set in kitchen appliances. [4]

Market-share estimates for major appliances genuinely disagree, and we report the disagreement rather than pick. Q4 2025 data put GE at ~20% unit share and LG at ~21% dollar share, with Samsung (~14–15%) and Whirlpool (~13–16%) close behind; a 2023 TraQline estimate instead ranked Samsung 21%, LG 19%, GE Appliances 18%, and Whirlpool 15%, or 73% combined. Different vendors, different years, and different bases (units vs. dollars) — the durable conclusion is a genuine four-way race in which foreign-owned brands hold the top spots, not a precise ranking. [5]

At the group level, the top four firms take 64.1% of revenue and the top eight 79.7% — a genuinely concentrated industry group. [3] Read that number with care, though: it sits between the two children's (58.6% and 70.3%) because it blends a moderately concentrated branch with an extremely concentrated one. No firm competes across the whole group, so the 3352 CR4 describes a statistical aggregate, not a real market. [4][5]

---

9. Risks

• Tariff and input-cost whiplash — the defining, shared risk. Flows straight into cost of goods for import-reliant small appliances (Hamilton Beach's $5.3M charge, 90bps of gross margin) and into metals costs for domestic major-appliance factories, where duties raise costs for everyone including domestic makers; price increases can outrun a weak consumer. [4][5][10]
• Consumer and housing cyclicality — discretionary, deferrable purchases across the board; major appliances additionally hostage to a high-rate, low-turnover housing market that Whirlpool describes as the weakest demand since 2008. [5]
• Retail concentration and channel shift — dependence on a few big retailers (Walmart 29% and Amazon 19% of Hamilton Beach's 2025 revenue; Lowe's ~15% of Whirlpool's sales and 44% of receivables), with ongoing migration to e-commerce and private label. [5][10]
• Thin, operating-leveraged margins (major white goods) — cyclical stress becomes balance-sheet stress fast (Whirlpool's dividend suspension and non-investment-grade downgrades). Note the exception inside the same code: replacement-driven water heating does not share this profile. [5]
• Fad and inventory risk (small) — short product cycles and low entry barriers on commodity goods invite fast obsolescence and Chinese direct competition; supplier bases are concentrated in a few countries. [4]
• Product liability and recall exposure — a shared, high-severity tail risk: 1.85 million recalled pressure cookers on the small side; on the major side a defect can trigger field repairs across a large installed base plus retailer chargebacks, with refrigerants and gas appliances raising the safety stakes. [4][5]
• Regulatory reversal in both directions (major) — efficiency rules can be paused, re-litigated, or reinstated, leaving manufacturers designing to a moving target while the existing 2028–2030 compliance dates still stand. [5]
• Foreign competition and access risk — LG and Samsung hold the top of the major-appliance market while Midea and Haier undercut on cost; and a direct U.S.-listed bet on either branch means concentrated single-name exposure (Whirlpool, A. O. Smith, or SharkNinja) or a foreign listing. [4][5]

10. How to invest & outlook

Routes in (full detail in the child primers):

• Growth / consumer-brand (small appliances): SharkNinja (NYSE: SN) is the group's clearest and largest listed growth story, on a growth multiple with tariff and execution risk; small-cap value/income via Hamilton Beach (NYSE: HBB) and National Presto (NYSE: NPK, whose earnings increasingly lean on its Defense segment); diversified exposure via Newell Brands, Helen of Troy, and Spectrum Brands; turnaround/distressed via iRobot. [4]
• Cyclical value (major appliances): Whirlpool (NYSE: WHR) is the only direct, U.S.-listed full-line pure-play — now a cyclical-recovery/total-return story after its 2026 dividend suspension, not an income holding, and increasingly an Americas-only exposure after its European major-appliance business was deconsolidated in April 2024 and its Indian business in 2025. [5]
• Replacement-demand quality (major appliances): A. O. Smith (NYSE: AOS) — water heating at ~24% North America segment margins, a genuinely different risk profile from white goods, though its boilers and water-treatment lines make it broader than this code. [5]
• International: foreign parents with U.S. appliance operations — Haier, LG Electronics, Samsung Electronics, Electrolux, Midea (major); Groupe SEB, De'Longhi, Breville, Techtronic Industries, Philips (small) — via foreign exchanges or ADRs; each is a diluted read inside a multi-segment global firm, and U.S. appliance results may be small or undisclosed. [4][5]
• Private markets: luxury built-in and private-equity-owned makers on the major side (Sub-Zero/Wolf/Cove, Thermador; 26North bought a Viking majority at an $885 million enterprise value in 2024), plus privately held water heating (Rheem, owned by Japan's Paloma; American-owned Bradford White); privately held small-appliance brands (Conair/Cuisinart, Dyson, Bissell, Vitamix, Lasko, Vornado); and on both sides contract manufacturers, component suppliers, distributors, installers, warranty administrators, and repair/parts rollups. [4][5]
• Watch the code boundary: Alliance Laundry (NYSE: ALH, IPO'd October 2025) and Middleby (Nasdaq: MIDD) are commercial equipment and sit outside NAICS 3352 — they are not exposure to this group. [5]
• Note: there is no dedicated ETF for this industry group; use consumer-discretionary and household-durables funds for broad exposure. [4]

Outlook. The group is a study in contrasts, and the revised child research makes the contrasts sharper rather than softer. The small-appliance branch offers moderate low-to-mid single-digit growth — but unevenly, with kitchen electrics and coffee rising while floorcare and personal care slipped — and winners are defined by sourcing flexibility, innovation and premiumization, and marketing and shelf/e-commerce dominance; the post-pandemic replacement cycle is a tailwind, cheap Chinese direct competition and trade-policy volatility the persistent headwinds. The major-appliance branch is a cyclical trough working toward recovery, with the unusual wrinkle that its most investable full-line name (Whirlpool) is also the one most exposed to a single national housing cycle — while the code's quietest corner, water heating, earns multiples of the margin without that exposure. Overhanging both is tariff policy, which has hit household appliances harder than almost any other consumer-goods category — a risk to importers and a reshoring catalyst for domestic producers at the same time. For depth on either branch, read the child primers. [4][5]

Federal statistics (sources 1–3, 6–8) are the ground-truth Census/SBA figures; because this 4-digit group has two 5-digit children each with a single 6-digit child, the 2022 Economic Census group totals equal the sum of 335210 and 335220. The children now also carry more recent 2023 Annual Integrated Economic Survey revenue readings ($3.60B and $23.6B), which is why the major-appliance child page reads $23.6B rather than the $23.7B implied by the 2022 Economic Census; those readings are reported separately and deliberately not summed into a 2023 group total. Where a metric is suppressed in the federal data (the HHI concentration index at this level), it is noted as such rather than estimated. Company, market-size, and market-share figures, and all forward-looking statements, come from the child primers and the company filings they cite, and are framed as judgments, not reported federal facts; where sources disagree — notably on U.S. major-appliance market share, and on the scope of third-party "market size" estimates for the two branches — the disagreement is stated rather than averaged away.
