Pottery, Ceramics, and Plumbing Fixture Manufacturing (NAICS 327110)

A Histometrics industry primer for public- and private-market investors

1. Overview

This is the industry that fires clay at high heat into finished goods: the toilet and sink in a bathroom, the china plate on a table, the porcelain insulator on a power line, and — increasingly — the precision ceramic parts inside a semiconductor tool or a hip implant. Formally, U.S. North American Industry Classification System (NAICS) code 327110 covers establishments that shape, mold, glaze, and fire pottery, ceramics, plumbing fixtures, and electrical supplies made wholly or partly of clay or other ceramic materials.[1]

Why an investor should care: this is a small, mature, moderately concentrated U.S. manufacturing niche — about $2.65 billion of domestic shipments and roughly 12,000 workers[2][3] — but it sits underneath very large end markets (housing, remodeling, foodservice, electronics) and it splits into two very different businesses. One end is commodity-cyclical and heavy (toilets and sinks, whose bulk and fragility protect domestic plants from imports). The other is a high-margin, spec-driven technical-ceramics business (parts for chips, medical devices, and electric vehicles) that grows with technology, not with housing starts.

Public vs. private ways in: there is essentially no U.S.-listed pure play in this code. The biggest domestic maker of vitreous-china fixtures, Kohler, is privately held; the other leaders (American Standard, TOTO, Duravit, Roca, Mansfield) are foreign-owned or private. The nearest listed exposure comes through foreign-listed sanitaryware makers (LIXIL, TOTO, Geberit) and through U.S. building-products companies (Masco, Fortune Brands Innovations) whose "plumbing" revenue is mostly metal faucets and fittings — a different NAICS code (see Section 2). The closest small-cap U.S.-listed direct exposure is FGI Industries, though its economics depend on imported sanitaryware and distribution rather than ownership of U.S. ceramic plants.[12][13][23]

2. What it is and how it's structured

In scope (327110): vitreous-china plumbing fixtures (toilets, urinals, bidets, wall-hung and pedestal sinks), china and earthenware bathroom accessories, earthenware and vitreous-china tableware and pottery, ceramic statuary and chemical stoneware, porcelain electrical insulators, and technical/advanced ("fine") ceramics such as ceramic magnets and engineered ceramic components.[1] In 2022 this code absorbed three older 2012 codes — 327111 (vitreous-china fixtures and bathroom accessories), 327112 (pottery and tableware), and 327113 (porcelain electrical supplies) — into one combined industry.[1]

Explicitly excluded — and where those dollars sit instead:

• Faucets, valves, shower trim, and other metal "fittings" → NAICS 332913, Plumbing Fixture Fitting and Trim Manufacturing. This matters enormously: the big U.S. "plumbing" names (Moen, Delta, Kohler faucets, Grohe) are largely here, not in 327110.[1]
• Ceramic wall and floor tile, brick, and refractories → NAICS 327120, Clay Building Material and Refractories Manufacturing.[1]
• Enameled iron and steel fixtures → 332999; plastic/cultured-marble fixtures → 326191; plastic bath accessories → 326199.[1]
• Glass tableware sits in glass manufacturing, not here.

So 327110 is best understood as the "ceramic body" of the bathroom and the table, plus a technical-ceramics tail — not the whole plumbing or homeware market.

Ownership mix: heavily private and foreign-owned. The 2022 Economic Census counted 536 firms operating 575 establishments,[2][3] but that employer count omits the large population of individual studio potters and artisan ceramicists who file as nonemployers — a genuine undercount at the craft end (see Section 3). At the industrial end, ownership concentrates in a handful of multinationals and family-held companies.

3. How big it is

Federal figures for the domestic industry (our ground-truth source, U.S. Census Bureau):

Concentration is moderate: the largest 4 firms make 52.4% of shipments, the top 8 make 62.9%, the top 20 make 76.4%, and the top 50 make 88.5%.[3] The Herfindahl-Hirschman Index (HHI, a standard concentration gauge where 1,500+ signals "moderately concentrated") is 954.7 — technically unconcentrated by U.S. antitrust thresholds even though the top four firms make just over half the output.[3] That combination — a low HHI but a high top-4 share — is the signature of a few large plants competing against a long tail of small ones.

Undercount caveats (important here):

• Imports dwarf domestic output for the light goods. The ~$2.65 billion figure is U.S. factory shipments only.[3] Most tableware, decorative pottery, and a large share of sanitaryware sold in the U.S. is imported, so domestic production badly understates U.S. consumption of these products.
• The "plumbing fixtures market" you see quoted is a different, bigger thing. Market-research figures that put North American plumbing fixtures and fittings in the tens of billions of dollars bundle in faucets/fittings (NAICS 332913), imports, and distributor margin — none of which is in 327110.[22] Do not compare the $2.65 billion Census number to those headline market sizes.
• Artisan potters are largely invisible. Individual, non-payroll ceramic artists don't appear in the employer statistics above.

4. The investable universe

There is no clean U.S.-listed pure play. Exposure is indirect — through foreign-listed sanitaryware makers, diversified ceramics groups, or U.S. building-products firms whose ceramic content is small.

Listed companies with relevant exposure

Major private / foreign-owned makers (the real center of 327110)

Investor takeaway: to own this industry directly you generally buy a foreign listing (LIXIL, TOTO, Geberit, Kyocera) or accept diluted exposure inside a diversified U.S. building-products or industrials name. The purest domestic assets (Kohler, CoorsTek, Fiesta) are not publicly traded. The small-cap FGI Industries offers the closest U.S.-listed direct commercial exposure but carries high customer and supplier concentration risk.[23]

5. How the money works

Owners in 327110 make money on a spread over materials, energy, and labor, and the economics differ sharply by segment.

The production process: Production normally begins by milling and blending clay, silica, and fluxing minerals with water into a plastic body or liquid "slip." EPA identifies ball clay, other clays, feldspar, and silica as principal sanitaryware feedstocks.[27] The material is cast, pressed, or otherwise formed, dried, inspected and glazed, then fired at high temperature — commonly 950°C to 1,370°C.[28] Continuous tunnel kilns offer lower unit energy costs at high utilization, while periodic kilns provide product flexibility but generally cost more per ton. Most tunnel, roller, and periodic ceramic kilns are fired with natural gas.[28] Sanitaryware may require assembly of separately cast sections, considerable manual finishing and inspection, and refiring or scrapping when cracks, warping, pinholes, or glaze defects appear.

Fixtures and tableware (the ceramic-body business):

• Inputs and firing. Raw materials are cheap and abundant (clay, feldspar, silica, glazes). Clay is not necessarily the largest cost; the real cost is energy: kilns fire at very high temperatures and run continuously, so natural-gas prices and kiln uptime are central to margins.
• Capacity utilization is the lever. These are high-fixed-cost plants. Profit depends on keeping kilns and casting lines full — spreading fixed cost across more units — and on yield (fired ceramic cracks and warps, so scrap/breakage rates directly hit cost). A modest volume decline can leave almost the same kiln, maintenance, and factory overhead spread over fewer saleable pieces.
• Freight is a moat. A toilet is heavy, bulky, and fragile — low value per pound. Shipping it across an ocean is expensive and risky, which gives domestic and regional plants a natural cost advantage on the heavy end (toilets, large sinks). The light end (plates, mugs, decorative pottery) travels cheaply and is therefore dominated by imports.
• Premiumization lifts price and margin. The growth strategy is to raise average selling price with one-piece toilets, integrated bidet/washlet seats, touchless flush, and designer collections. TOTO's U.S. expansion is explicitly aimed at "high-end one-piece toilets" and Washlet seats.[7]
• Replacement demand steadies the cycle. Toilets, tank parts, and seats wear out and get remodeled independent of new construction, giving a recurring repair-and-remodel base under the more cyclical new-build volume.

Profitability benchmarks: Geberit, at the higher-quality end of global sanitary products, reported a 29.4% EBITDA margin in 2025, with direct materials and personnel each representing 26.4% of sales; management identified volume, factory efficiency, and material prices as favorable margin variables and wage inflation, energy, outbound freight, and currency as headwinds.[25] This demonstrates what brands, specification power, and efficient manufacturing can earn — not the average profitability of 327110. FGI Industries, as an importer/distributor rather than a manufacturer, reported a 27.0% gross margin and a GAAP operating loss in 2025 — importer/distributor economics, not a manufacturing-margin benchmark.[23]

Technical / advanced ceramics (CoorsTek, Kyocera, CeramTec):

• This is an engineered-components business with pricing power, not a commodity. Parts are qualified into a customer's process (a chip-etch tool, an orthopedic implant, an EV inverter), which makes the supplier sticky and margins high.
• It is R&D- and specification-intensive; growth tracks electronics, medical, and EV demand rather than housing. The broader advanced-ceramics market is estimated around $12.9 billion in 2025, projected to reach roughly $17.2 billion by 2030 (~6% annual growth) — a very different trajectory from mature sanitaryware.[15]

Artisan pottery: small-batch, labor-intensive, sold direct-to-consumer or wholesale at craft margins; economically real but statistically under-captured.

Price trends: The BLS producer-price index for NAICS 327110 reached 166.198 in May 2026 (December 2011 = 100), reflecting substantial price increases since the pandemic-era input and freight shock.[29] This index measures domestic producer prices, not real shipment growth.

6. What drives demand

• Residential remodeling and repair. The steadiest driver. An aging U.S. housing stock and a structurally larger remodeling share of construction support ongoing fixture replacement. The median owner-occupied U.S. home was 41 years old in 2023, up from 31 years in 2005, and approximately 48% of owner-occupied homes were built before 1980.[30] This aging stock supplies a structural replacement base.[19]
• New housing construction. Single-family starts are the swing factor for volume; industry outlooks generally expect single-family starts to firm modestly while multifamily stays soft into 2026 (a forward-looking judgment).[19]
• Non-residential building. Hotels, offices, schools, hospitals, and stadiums buy fixtures in bulk; commercial cycles move the contract/spec segment.
• Water scarcity and efficiency. Drought and utility rebates pull demand toward high-efficiency and dual-flush toilets, favoring makers who can hit tighter flush specs (Section 7). Older low-flow toilets developed a reputation for poor flushing, so modern performance engineering and certification matter commercially rather than merely for compliance.
• Premium and wellness trends. Bidet/washlet seats, smart toilets, and spa-style bathrooms raise unit prices in the developed market. Premiumization is moving value from the ceramic bowl alone toward integrated systems: rimless designs, concealed carriers, touchless flushing, heated seats, bidet washing, drying, deodorization, and connected controls — meaning an increasing share of the customer's spending goes to electronics, seats, valves, and installation components that may fall outside 327110.
• Foodservice cycles. Restaurant and hotel openings drive commercial tableware; breakage creates replacement demand.
• Technology end markets. Semiconductors, electric vehicles, telecom, and medical devices drive the advanced-ceramics tail — the fastest-growing demand source in the code.[15]

7. Regulation

• Federal water-efficiency mandate. Under the Energy Policy Act of 1992, U.S. toilets have been capped at 1.6 gallons per flush (gpf) since 1994 — a rule that reset the entire product line decades ago.[5]
• EPA WaterSense (voluntary label). The U.S. Environmental Protection Agency's (EPA) WaterSense program certifies "high-efficiency" toilets at 1.28 gpf — 20% below the federal standard — while still passing a flush-performance test. WaterSense is voluntary but is widely referenced by codes and utility rebates. EPA issued a Version 2.0 tank-type specification in May 2024 but has paused its effective date, leaving Version 1.2 in force.[5]
• State overlays. California, Colorado, Texas, New York, and others require 1.28-gpf (or tighter) fixtures through state efficiency laws and green building codes, effectively making WaterSense-level performance mandatory in large markets (reported, and evolving).
• Lead-in-water rules. Federal "lead-free" limits on wetted surfaces primarily bite on metal faucets/fittings (332913); they touch ceramic bodies less, but full assemblies must comply.
• Air emissions and environmental compliance. Kilns are combustion sources, so plants operate under Clean Air Act permitting; energy and emissions rules feed straight into operating cost. EPA regulates acid gases, particulate matter, metals, and mercury from covered clay-ceramics facilities under the NESHAP.[27] Greenhouse-gas reporting under Subpart ZZ applies to qualifying ceramics plants that consume at least 2,000 tons ofite feedstocks annually and operate a kiln, dryer, or oven.[31]
• Worker safety — silica exposure. OSHA identifies ceramic-product manufacturing as a source of respirable crystalline silica, which is associated with silicosis, lung cancer, chronic obstructive pulmonary disease, and kidney disease. Glazes may also create metals exposure and hazardous-waste obligations.[32]
• Trade remedies. Ceramic goods from China face Section 301 tariffs (25% on most affected products, with further increases finalized in September 2024),[16] and ceramic tile (adjacent code 327120) carries antidumping duties well above 300%.[17] Antidumping/countervailing-duty petitions targeting Chinese ceramic sanitaryware have also been pursued.[18] Plumbing Manufacturers International has identified toilets, sinks, and plumbing components as products affected by Section 301 tariff actions.[33] Trade policy is a first-order swing factor for import-exposed segments.

8. Competitive dynamics and consolidation

• A few large plants, a long tail. The concentration data (top-4 = 52%, HHI under 1,000) describe an industry led by several scaled multinationals — Kohler, LIXIL/American Standard, TOTO, Roca, Duravit — competing above a fragmented base of small potteries and specialty shops.[3] Plumbing Manufacturers International's manufacturing membership includes Kohler, LIXIL, TOTO USA, and Gerber, though its broader plumbing-industry statistics also encompass faucets, valves, fittings, wholesaling, and retailing — they are not valid measures of NAICS 327110 alone.[34]
• Import competition splits by weight. Domestic makers hold the heavy, freight-protected end (toilets); imports dominate light tableware and decorative ware. Tariffs and freight economics, not just product quality, decide who wins each subsegment.[16][17]
• Reshoring at the premium end. TOTO's new $224 million Morrow, Georgia plant — raising U.S. luxury-toilet capacity ~150% and adding ~300,000 units/year of local production — is a notable bet on domestic manufacturing for supply-chain resilience and speed to market.[7]
• Consolidation of legacy brands. Ownership has globalized: American Standard sits inside Japan's LIXIL; Mansfield inside Colombia's Corona; and in tableware, Homer Laughlin's foodservice lines moved to Britain's Steelite in 2020 while the retail Fiesta business stayed independent.[9][20][21] Cross-border acquisition, not domestic roll-up, is the dominant pattern.
• Technical ceramics is its own contest. Here the rivalry is Kyocera vs. CoorsTek vs. CeramTec/Morgan on materials science and qualification into customer processes — a higher-margin, more defensible game than sanitaryware.[14][15]

9. Risks

• Housing and construction cyclicality. New-build fixture volume swings with starts and mortgage rates; a construction downturn hits hard.
• Energy cost shocks. Continuous high-temperature firing makes margins sensitive to natural-gas prices. Kilns cannot be run economically at arbitrary utilization levels; natural-gas price spikes, outages, or carbon regulation can compress margins or render older plants uncompetitive.
• Import and trade-policy whiplash. Tariff changes cut both ways — protecting domestic plants but raising costs and inviting retaliation; the light-goods segments remain structurally exposed to low-cost imports.[16][17]
• Capital intensity and inflexibility. Kilns are expensive and hard to idle; utilization shortfalls quickly erase profit. Firing defects, kiln failures, and mold problems can simultaneously reduce output and raise unit energy cost.
• Offshoring of tableware/pottery. Decades of migration to Asia have hollowed out domestic tableware; the remaining U.S. potters compete on "Made in USA," design, and speed rather than price.
• Substitution. Plastic, cultured-marble, stainless-steel, fireclay-composite, and enameled-metal fixtures (all in other NAICS codes) can take share on price or design. Substitution can reduce this NAICS industry's output without reducing the broader plumbing-fixture market.
• Customer and supplier concentration. FGI Industries illustrates importers' bargaining-power risk: its ten largest customers represented 66% of 2025 sales, and one supplier represented 83.3% of accounts payable at year-end.[23]
• Labor availability. Automation can improve casting, glazing, and handling, but irregular sanitaryware shapes and cosmetic inspection retain manual content. Skilled maintenance and process-control personnel are important because a poorly controlled drying or firing curve can destroy an entire production batch.
• Concentration for private/foreign owners. Because the best assets are private or foreign-listed, public-market investors bear currency risk and limited disclosure, and cannot easily buy the domestic leaders directly.

10. How to invest and the outlook

Public-market routes:

• Foreign-listed pure(ish) plays: LIXIL (TSE: 5938; owns American Standard), TOTO (TSE: 5332; ADR TOTDY), Geberit (SIX: GEBN), Globe Union (TWSE: 9934; owns Gerber), and Kyocera (TSE: 6971 / NYSE: KYO) for technical ceramics.[7][8][9][10][15][26] These carry currency and governance considerations for U.S. buyers.
• Small-cap U.S.-listed: FGI Industries (NASDAQ: FGI) is the closest direct commercial exposure, but it is primarily a brand owner and importer rather than a domestic ceramic manufacturer, and carries high customer and supplier concentration risk.[23]
• Diversified U.S. building-products proxies: Masco (NYSE: MAS) and Fortune Brands Innovations (NYSE: FBIN) give exposure to the bathroom and kitchen theme, but their revenue is mostly metal faucets/fittings and spas (NAICS 332913), not ceramic fixtures — a proxy, not a pure play.[11][12][13]

Private-market routes:

• The crown-jewel domestic assets — Kohler, CoorsTek, Fiesta Tableware — are held privately, so access comes through direct/private-equity ownership, supplier and distributor businesses, or specialty technical-ceramics companies serving semiconductor, medical, and EV supply chains (the higher-growth, higher-margin corner).[14][15]
• The diligence distinction is crucial. A brand may report substantial toilet sales while owning no U.S. ceramic production, whereas a plant may make insulators or magnets with no housing exposure. Relevant underwriting should separate revenue by product and manufacturing location, then examine kiln age and fuel efficiency, practical capacity, saleable yield, mold ownership, environmental permits, silica controls, customer concentration, freight radius, warranty claims, and maintenance capital expenditure.

Near-term drivers to watch (forward-looking):

• The remodeling cycle and single-family housing-starts recovery set volumes for fixtures.[19]
• Water-efficiency policy (WaterSense revisions, state 1.28-gpf mandates) and premiumization (bidet seats, smart toilets) lift average selling prices even when unit volume is flat.[5][7]
• Trade policy — the level and coverage of Section 301 and sanitaryware antidumping actions — will keep reshaping the import-vs-domestic split.[16][18]
• Technical-ceramics demand from chips, EVs, and medical devices is the structural growth story inside an otherwise mature code, and is where the most attractive private and foreign-listed exposure sits.[15]

Bottom line (analytical judgment): 327110 is a small, mature, import-pressured domestic manufacturing base with a genuinely attractive high-tech tail. For most investors it is a thematic exposure bought indirectly, not a sector with a domestic pure-play stock — with the sanitaryware end offering steady replacement-driven cash flows and the advanced-ceramics end offering the real growth. The two most common misreports are consequential: calling 327110 "the toilet industry," and treating U.S. brand revenue or imported product sales as domestic NAICS manufacturing output. Neither is supported by the Census definition.
