Blind and Shade Manufacturing (U.S., NAICS 33792)

Short primer — single-child pass-through. At the five-digit level of the North American Industry Classification System (NAICS), industry 33792 contains exactly one six-digit child, 337920 (Blind and Shade Manufacturing), and the two are effectively identical. This page gives the rollup's own federal figures and points you to the child primer for full detail. For the complete treatment — economics, named companies, regulation, and how to invest — read the [337920] primer.

1. Overview

NAICS 33792 is the business of making window coverings — the hard, mechanical kind: Venetian blinds, vertical blinds, roller shades, cellular ("honeycomb") shades, Roman shades, solar screens, plus the curtain rods and drapery hardware that hang beside them [11]. It sits where housing, home improvement, and the smart-home electronics that motorize a shade all meet. The soft goods — sewn curtains and draperies — are a different industry (NAICS 314120), and so is the retail measure-and-install layer that most customers actually buy from [11].

For an investor, this is a small, mature, housing-cycle-sensitive manufacturing niche where demand tracks home sales, remodeling, and new construction, and where the economics are being reshaped from two directions at once — cheap imported finished blinds pressuring the commodity end, and motorization lifting the premium end [3]. The long-run direction of domestic production is unambiguous: U.S. employment in blind-and-shade manufacturing fell from 26,182 in 2000 to 8,450 in 2024, a 67.7% decline, on the Bureau of Labor Statistics' count [13]. There is no meaningful U.S.-listed pure play; the leaders are private and the cleanest listed pure play is foreign (see §4).

2. What's inside — and why this level equals its one child

NAICS is a nested system: each five-digit industry breaks into one or more six-digit national industries. NAICS 33792 is one of the cases where the split is trivial — it has a single child:

Because the mapping is one-to-one, every dollar of shipments, every firm, and every worker counted under 33792 is the same set counted under 337920. There is no aggregation across differing sub-industries to reconcile and no allocation to worry about — the level is its child. That is why this page stays short: the substance lives in the [337920] primer.

The one distinction worth carrying up from the child is not a sub-industry split but an operating-model split that runs through every firm at this level: stock (ready-made, fabricated before sale, sold through home centers and e-commerce) versus custom (measured, then cut and assembled to order, and usually professionally installed). A U.S. Consumer Product Safety Commission (CPSC) analysis estimated custom products at roughly 44% of units but a disproportionate share of revenue [5]. That divide, not the code hierarchy, is what separates the industry's economics.

3. How big it is (this level's rollup figures)

Core federal figures for NAICS 33792, drawn from our ingested ground-truth stats (stats-33792.md). These match the 337920 figures because the level equals its one child:

So this is a genuinely small manufacturing industry — roughly 8,500–10,700 U.S. factory workers and under $3 billion in domestic factory shipments. (The HHI, a standard market-concentration index, is withheld by the U.S. Census Bureau for this industry, so we do not report a value [1].) That the U.S. Small Business Administration treats a maker with up to 1,000 employees as a small business [1] tells you how few plants approach even that scale.

Three caveats when you meet a different number:

1. The two federal employment series disagree, and you should not average them. Census County Business Patterns puts 2023 employment at 10,694 [1]; BLS puts 2024 at 8,450 [13]. Different programs, different reference years, different coverage rules. The direction is what matters — both sit in the same shrinking range, and the BLS long series shows a 67.7% decline since 2000 [13]. Read that as a contraction in domestic payroll manufacturing driven by imports, automation, and productivity, not as an equivalent decline in end demand.
2. Federal shipments ≠ the retail market. Market-research firms cite a U.S. "window coverings" market near $3.8 billion in 2024 and a global blinds-and-shades market above $6 billion [2][9]; a CPSC analysis estimated the broader U.S. window-coverings market at about $6.7 billion in 2021 [5]. Those end-market figures include imported finished product and retail/installation markup, so they run well above the ~$2.6 billion of domestic factory shipments the Census measures. Independent industry analysis puts 2026 U.S. manufacturing revenue near $2.2 billion [3]. The gap is largely the imports story.
3. Undercount at the edges, not the core. The federal manufacturing count is reasonably complete for the factories themselves — the top firms are large enough to be captured. The real blind spot is the boundary: much of what a customer pays for a custom blind is created downstream in measuring, assembly-to-order, and installation by dealers, franchises, and trade contractors classified as retail or construction, not manufacturing. Counting only NAICS 33792 therefore understates the economic footprint of "the blinds business" as a whole.

4. The investable universe (where value concentrates)

Because the level equals one child, value concentrates exactly where it does at 337920: at the top of a three-tier ownership structure — a handful of large branded manufacturers (mostly private-equity or family-owned), a middle of mid-size and contract (commercial) shade makers, and a long tail of small fabrication shops [1][3]. There is no clean U.S.-listed pure play:

• Nien Made Enterprise (Taiwan Stock Exchange: 8464) — the world's largest window-blind maker by volume and the cleanest listed pure play, with ~$960M TTM revenue and ~$3.1B market cap in mid-2026 [8]. It also shows what the premium end can earn: 59.1% gross, 28.1% operating, 22.5% net margin in Q1 2026, with window coverings at 96.4% of group revenue [17]. It carries real concentration risk — one customer was 39% of revenue and the Americas 76% in its 2022 filing [18] — and it is foreign-listed.
• Somfy SA (Euronext Paris: SO) — the listed way to own the motorization theme via tubular motors and controls, not blinds themselves [12].
• Home Depot / Lowe's (NYSE: HD / LOW) — the dominant U.S. retail channel, not manufacturers; neither separately discloses blind-and-shade sales or margins, so exposure is heavily diluted.
• Hunter Douglas — the global leader, now private: 3G Capital took a 75% controlling interest in February 2022 (≈$7.1B enterprise value) with the founding Sonnenberg family retaining 25% [6], and the public shares were delisted on October 31, 2022 [19]. Springs Window Fashions — the custom-coverings leader, owned by Clearlake Capital since 2021 [7]. Lutron Electronics — premium motorized shading and controls, family-owned [12].

Full company detail, tickers, brand maps, and the private-market layer are in the [337920] primer.

5. How the money works

Identical to 337920. Owners earn along two economic models whose mix sets margins: made-to-order (custom) — build-to-order, light finished-goods inventory, modest working capital, brand pricing, the profit engine — and stock/ready-made — standard sizes made in volume for big-box shelves, price-driven, thin-margin, and most exposed to imports and retail buyer power [3][8]. Because a custom blind is bulky, size-specific, and time-sensitive, speed to the customer is the reason a domestic (and nearshore) footprint survives at all: Nien Made disclosed that Mexican production cut quoted North American custom delivery times to roughly two weeks from five to seven [18].

On margins, be careful what you generalize. No reliable current U.S. industry-average margin is available. The only disclosed figures belong to scaled, vertically integrated global platforms: Hunter Douglas's worldwide Window Coverings segment earned 42.1% gross and 16.9% operating margin on $4.292 billion of revenue in 2021 [16], and Nien Made's Q1 2026 margins are cited above [17]. Those are consolidated multinational results — evidence of what premium custom mix, branding, and efficient offshore production can attain, not a benchmark for a 20-person U.S. fabrication shop.

The clearest lever to grow revenue per unit in a low-unit-growth market is motorization (a motor plus app/voice control multiplies average selling price and pulls in electronics content) [12]. Input costs — aluminum, PVC/resin, fabric, oil-based synthetics, freight — pass through into prices over time but not instantly, so inflation spikes compress margin before price increases land [16]. And increasingly, domestic "manufacturing" is really fabrication and assembly of imported components — a big reason federal factory shipments have drifted down even as the retail market grew [3].

6. What drives demand

The same drivers as the child: housing turnover (existing-home sales, which move inversely with mortgage rates), repair-and-remodel (the largest, most stable slice), new residential construction, commercial/architectural (contract) shade demand, motorization and smart-home adoption (automated shades now integrate with lighting, HVAC, and building-management systems), energy efficiency (insulating cellular shades and automated daylighting), and the cordless-safety replacement cycle seeded by tightened standards (see §7) [3][4][12].

7. Regulation

The defining theme is child safety — strangulation risk from accessible pull cords. The operative baseline is the voluntary consensus standard ANSI/WCMA A100.1 (American National Standards Institute / Window Covering Manufacturers Association). Its 2018 revision required nearly all stock products to be cordless or have inaccessible cords; the 2022 revision extended cord restrictions to custom made-to-order products, with a compliance date of June 1, 2024 [4].

Correction to earlier guidance on this page: the CPSC's mandatory federal rule on operating cords for custom window coverings, finalized in late 2022 [5], was vacated by the D.C. Circuit on September 12, 2023 [14]. It is therefore not the case that a mandatory federal rule currently bans every cord on custom products. What remains in force is the voluntary ANSI/WCMA A100.1-2022 standard as the industry baseline, plus CPSC business guidance on cord accessibility, inner-cord limits, and product marking, and the CPSC's separate substantial-product-hazard regime [15]. The practical effect on manufacturers is largely unchanged — the redesign to cordless and shrouded systems has already happened — but the legal basis matters for anyone modelling compliance or enforcement risk. Secondary themes: flammability standards for contract fabrics and — increasingly consequential — trade policy (tariffs and antidumping/countervailing duties on finished blinds and components) [10]. See the [337920] primer for the full regulatory detail.

8. Consolidation

Federal concentration data for 2022 apply unchanged to this level [1]: the top 4 firms make 48% of shipments (CR4), the top 8 make 63.1% (CR8), the top 20 make 75% (CR20), and the top 50 make 87.6% (CR50) — moderately-to-highly concentrated at the top, fragmented at the bottom. A CPSC analysis of the broader retail market found three manufacturers accounting for almost 38% of 2020 dollar sales [5]. These figures understate real market concentration because they exclude the large volume of finished blinds imported from a few dominant foreign producers such as Nien Made [8].

Private equity has rolled up the branded leaders (3G Capital → Hunter Douglas; Clearlake → Springs Window Fashions) [6][7], and the sponsors are visibly running a bolt-on playbook — Springs added Sunburst Shutters in 2023 and PowerShades in 2025, extending into shutters and motorization [20]. The retail/installer layer stays fragmented, which is where much downstream margin lives.

9. Risks

The same risk set as 337920: housing-cycle sensitivity (rate-driven volumes, plus general consumer confidence) [3][16]; import competition and tariff whipsaw — a high share of U.S. consumption is imported, duties on Chinese blinds have historically reached ~25% (with base rates near 11% on synthetic-fiber shades), and 2025 tariff actions added surcharges that manufacturers largely passed through as 8–15% wholesale price increases [3][10]; input-cost inflation (aluminum, PVC/resin, fabric, freight) with slow pass-through to big-box buyers [16]; product-safety liability (cord recalls, redesign, testing, and litigation) [4][15]; channel buyer power from a few home-center chains; the technology-investment burden of staying relevant in motorization, which now also carries electronic-component, software-support, and interoperability risk [12]; and substitutes — curtains and draperies (outside this NAICS), shutters, window film, and electrochromic glazing, which squeeze from both the low and high ends. One practical monitoring gap: BLS discontinued the industry-level producer-price index for this industry, so direct price tracking is now limited [21].

10. How to invest and outlook

Because 33792 equals 337920, the investment map is identical. Public-market routes are all imperfect — Nien Made (Taiwan: 8464) as the only clean listed pure play, though geared to the commodity/stock end and carrying customer-concentration and currency risk [8][18]; Somfy (Paris: SO) for the motorization theme [12]; and Home Depot/Lowe's for diluted channel exposure. There is no U.S.-listed pure play; the branded leaders are in private hands [6][7]. Private-market routes are where the industry is genuinely accessible — small-business acquisition of fabrication-and-install shops, franchise/dealer businesses (e.g., Budget Blinds), and private-equity co-investment [1][6][7]. In diligence, the question that matters most is the one this level's structure keeps pointing at: what share of earnings is branded custom versus big-box stock, and how much of the current margin is temporary commodity pass-through.

Outlook (forward-looking judgment, not fact): a small, mature, import-pressured niche with a shrinking commodity core and a growing premium (motorized, custom, contract) edge — best understood as a private-market industry rather than a public-equity one. The dominant swing factor is housing turnover; motorization mix-shift is the most reliable growth lever; trade policy is a two-way wildcard that could accelerate nearshoring while raising imported-component costs; and the cordless-safety replacement cycle provides a steady demand floor [3][4][10][12][15]. For the full argument, read the [337920] primer.
