Tortilla Manufacturing in the United States (NAICS 311830): An Investor's Primer

NAICS (North American Industry Classification System) code 311830 covers U.S. establishments that primarily make tortillas.

1. Overview

Tortillas are one of the quiet success stories of American food. What was once an ethnic-aisle specialty is now the second best-selling bread in the country, behind only sliced loaf bread and ahead of bagels, buns, and rolls, according to the Tortilla Industry Association [1]. Corn and flour tortillas anchor tacos, burritos, wraps, quesadillas, and — increasingly — low-carb and high-protein "better-for-you" eating.

For an investor, the appeal is a staple food with steady, above-bread growth, but the industry is unusual in one respect: there is no large, pure-play U.S.-listed tortilla company to buy. The category is dominated by one Mexican multinational (Gruma, maker of Mission tortillas) and rounded out by big diversified bakers and a long tail of privately held regional producers. So the practical ways in are (a) buying Gruma or a diversified packaged-food company through public markets, or (b) private-market routes — owning, buying, or lending to one of the many family- and private-equity-owned regional tortilla makers. Both sides are covered below.

2. What it is and how it's structured

Scope. NAICS 311830 is establishments primarily engaged in manufacturing tortillas — corn and wheat-flour tortillas sold to grocers, foodservice operators, and food companies [2]. The industry principally makes packaged corn and wheat-flour tortillas, including products marketed as wraps, along with foodservice tortillas made to restaurant specifications. Producers compete across mainstream, Hispanic-focused, value, private-label, foodservice, and premium "better-for-you" segments such as low-carbohydrate, high-protein, whole-grain, and gluten-free products. Mission Foods, for example, markets Mission as a broad national brand, Guerrero toward Hispanic consumers, and Calidad as a value brand [3].

Corn tortillas start from masa, a dough made by nixtamalization: cooking and soaking corn in an alkaline lime (calcium hydroxide) solution, then grinding it — either as fresh wet masa or reconstituted from dry masa flour [4][5]. Wheat-flour production mixes flour, water, fats or oils, salt, leavening, conditioners, and preservatives into dough, then portions and forms it by hot press, die cutting, or related processes before baking, cooling, inspecting, and packaging. Flour specifications differ by forming process and desired flexibility, shelf life, and end use [6].

What it excludes (adjacent NAICS codes). The classification is narrower than "everything tortilla":

• Tortilla chips are not here — they fall under NAICS 311919, Other Snack Food Manufacturing [2]. This matters because the biggest player, Gruma, runs a large tortilla-chip business whose output is counted elsewhere.
• Frozen tortilla-based dishes (e.g., frozen enchiladas, burritos) go to NAICS 311412, Frozen Specialty Food Manufacturing, and canned versions to 311422, Specialty Canning [2].
• Corn masa flour and wheat flour themselves are milling — NAICS 311221 (Wet Corn Milling) and 311211 (Flour Milling) — i.e., a key raw material, not this industry.
• Tortillas made and sold on-site by restaurants (taquerías, Mexican grills) or in-store by supermarket bakeries are foodservice/retail, not manufacturing.

Ownership mix. A concentrated top tier of large, professionally run manufacturers (foreign-parent and domestic) sits above a long tail of privately held, often family-founded regional tortillerías. There are effectively no government or cooperative operators. The industry is not dominated by tiny sole proprietors the way, say, landscaping is — but the small end is real and, as noted below, partly invisible to federal manufacturing statistics.

3. How big it is

Our ground-truth federal figures:

That works out to roughly $14.7 million in receipts per firm (2022) and an average annual wage near $47,000 per worker (2023 payroll ÷ employees) [7][8] — a capital-lighter, lower-wage food-manufacturing profile than, say, meatpacking or beverages. The establishment distribution illustrates the industry's long tail: of the 428 establishments in 2023, 136 had fewer than five employees, while seven employed between 500 and 999 [8].

The undercount caveat. These figures likely understate how many tortillas Americans actually make and eat, for structural reasons:

• Neighborhood tortillerías, supermarket in-store bakeries, and restaurant on-site production are classified under retail bakeries (311811), grocery, or foodservice (NAICS 722) — not here.
• Gruma's and others' tortilla-chip volume sits in snack-food manufacturing (311919), not 311830.
• Very small operators can fall below survey thresholds. So "how big is the tortilla business" and "how big is NAICS 311830" are different questions. Private market-research estimates that measure retail sales value (and sometimes bundle wraps, flatbreads, or chips) run higher — IBISWorld pegs the manufacturing industry around $6.5 billion for 2026, and broader "tortilla market" tallies reach $8–9 billion [9][10]. Commercial market-research figures frequently broaden the product universe or mix retail sales with manufacturer shipments. We prefer the federal $5.93 billion for the manufacturing industry itself, with the caveat that true U.S. tortilla output is larger once retail- and restaurant-made product is added.

Concentration. This is a top-heavy industry. The four largest firms took 62.5% of revenue in 2022; the top eight, 69.5%; the top 20, 80%; and the top 50, 90.1% [11]. (The Herfindahl-Hirschman Index, a standard concentration measure, is suppressed in the federal data and so is not reported here [11].) In plain terms: a handful of national manufacturers dominate, with hundreds of small regional players sharing the remaining ~10%.

4. The investable universe

There is no large, dedicated, U.S.-exchange-listed pure-play tortilla company. The public exposure is concentrated in one foreign-listed leader plus diversified food companies for whom tortillas are a slice of a much bigger business. Tickers and market values are for the parent, not a tortilla-only unit.

BMV = Bolsa Mexicana de Valores (Mexican Stock Exchange); ADR = American Depositary Receipt, a U.S.-traded certificate representing foreign shares; OTC = over-the-counter (traded off-exchange). Note: Gruma delisted its full NYSE ADR (former ticker GMK) in September 2015 and now trades in the U.S. only as a thin, unsponsored OTC ADR — most liquidity is on the Mexican exchange [12][17]. GRUMA terminated its sponsored ADR program and its U.S. Exchange Act reporting obligations ended on December 9, 2015 [3].

A caution on share calculations. Comparing Gruma USA's $3.45 billion in segment sales with the Census industry's $5.93 billion in shipments and calling the quotient "market share" is a common analytical error. The numerator includes corn flour, tortilla chips, and related products, while the Census denominator excludes tortilla chips and classifies establishments by their primary activity [3][7]. Retail sales, manufacturer shipments, foodservice sales, and broad "tortilla products" estimates are likewise not interchangeable.

Major private / other owners (not publicly traded):

• Olé Mexican Foods (Norcross, GA; founded 1988) — family-owned; brands La Banderita, Olé, La Centroamericana, Verolé; La Banderita is a ~$600M brand growing ~10%/year [10][18][19].
• Flagship Food Group — private-equity platform controlling La Tortilla Factory and Tortilla King [20].
• El Milagro (Chicago), Aranda's, Rudy's, Tortilla Land, Don Pancho, Reser's Fine Foods — strong regional and private-label producers, several private-equity- or family-owned, with local loyalty national brands have never fully cracked [3][10].
• Private label (store brands, made by contract manufacturers) — roughly $422M in tracked retail sales, up ~10.8% year over year [10].

5. How the money works

Tortilla manufacturing is a high-volume, thin-margin commodity conversion business: buy corn (as masa or masa flour), wheat flour, oil/shortening, and packaging; convert them on continuous ovens into a perishable product; and sell it. Owners make money on the same levers as most food manufacturers, tuned to this category:

• Volume × price/mix. Revenue is tonnes shipped times price. In FY2025, Gruma USA reported $3.45 billion in sales on 1.535 million metric tons — sales volume fell 3% year over year, which management attributed to foodservice price sensitivity and weak consumer confidence [3]. Watching volume and price/mix separately tells you whether growth is real demand or just cost pass-through.
• Input-cost spread and cyclicality. Corn and wheat are traded commodities; margins swell or compress with grain, oil, energy, and freight costs. At the consolidated GRUMA level, corn represented 33% of 2025 cost of sales, wheat flour 9%, and energy approximately 5% [21]. There is little pricing power on plain tortillas (private label sets a ceiling), so gross margin is driven by input hedging and plant efficiency rather than premium pricing.
• Capacity utilization and throughput. Ovens and packaging lines are the fixed cost. Keeping lines full and automating labor is how a manufacturer defends its unit cost — classic manufacturing economics. Gruma USA reported annual capacity of approximately two million metric tons and 79% average utilization in 2025; capital expenditures over the preceding three years totaled $225 million, directed primarily to capacity, manufacturing, and technology upgrades [3].
• Distribution as the moat. Fresh tortillas are perishable and low in value per pound, so shipping them far is uneconomic. Winners run dense regional plant networks feeding DSD (direct-store-delivery) systems that put product on shelves and rotate it. Mission distributes principally through DSD using independent distributors who visit stores daily or several times per week; warehouse distribution is a smaller channel [3]. Gruma's 21 U.S. plants and DSD reach are its real advantage, more than any recipe [3][12][10].
• Premium niches carry the margin. The commodity core is low-margin, but better-for-you formats — grain-free, low-carb/"zero net carb," high-protein, gluten-free — command higher prices and margins and are where innovation dollars flow (more in Section 6).

Operating economics. Gruma USA reported $568.2 million in operating income on $3.45 billion in sales in FY2025, an operating margin of 16.5%. Cost of sales was 56.1% of revenue and selling and administrative expenses were 27.8%; the company attributed margin improvement to manufacturing efficiencies [3]. Note that Gruma USA is not a pure NAICS 311830 comparable because it includes corn-flour milling, tortilla chips, and related products — its integrated margin should not be substituted for an industry-wide figure.

A useful frame for owners: steady, defensive base volume (grocery) plus a more cyclical, higher-growth foodservice channel, with profitability swinging on the grain/oil cost cycle and on how much of the mix is premium versus plain. Seasonality is modest: GRUMA reports slightly higher tortilla volumes during summer promotions and sporting events, followed by a small year-end decline [3].

6. What drives demand

• Demographics. The U.S. Hispanic population grew about 26% from 2010 to 2022, a durable base of tortilla demand [22]. The Census Bureau estimated just over 65 million Hispanic residents in 2023, equal to 19.5% of the U.S. population; the group grew by 1.16 million, or 1.8%, from the prior year and accounted for just under 71% of total U.S. population growth [23]. Growth increasingly comes from non-Hispanic households.
• Mainstreaming and versatility. Tortillas have crossed over as wraps, pizza bases, breakfast burritos, and snack bases across all demographics, which is what lifted them to the No. 2 bread slot [1]. GRUMA cites non-Hispanic adoption, wraps, product innovation, and broader distribution as demand drivers [3].
• Health and diet trends. Low-carb, high-protein, high-fiber, gluten-free, and grain-free eating has spawned a multi-hundred-million-dollar premium tortilla segment. Manufacturers are now explicitly courting GLP-1 (the weight-loss/diabetes drug class, e.g., Ozempic) users with low-calorie, "every bite counts" positioning — Mission markets a Zero Net Carbs line to exactly this shopper [10]. The countertrend is consumer trade-down to private label and value brands when grocery budgets tighten; retailer consolidation can amplify both effects by increasing promotional demands and shifting shelf space toward store brands.
• Foodservice. Quick-service and fast-casual Mexican chains (tacos, burritos, wraps) are a large, but more cyclical, demand channel. Mission reported that retail represented approximately 85% of its U.S. sales volume in 2025, with the remainder largely foodservice and institutional customers [3]. Household spending on food away from home averaged $3,945 in 2024 but increased only 0.3% from 2023, consistent with a slowing restaurant environment [24].

7. Regulation

Tortilla making is regulated as food manufacturing, primarily by the FDA (U.S. Food and Drug Administration):

• Food safety. Plants operate under the FDA's FSMA (Food Safety Modernization Act) preventive-controls rules. Covered facilities generally must comply with current good manufacturing practices and maintain written hazard analyses, preventive controls, allergen controls, sanitation controls, verification records, supplier programs, and recall plans [5][25]. Wheat is a major allergen, creating cross-contact and labeling obligations for plants producing both wheat and gluten-free products.
• Fortification — the live issue. The FDA permits adding folic acid (a B-vitamin that reduces neural-tube birth defects) to corn masa flour, up to 0.7 mg per pound [26]. Historically optional, it is becoming mandatory in places: California enacted AB 1830, requiring covered corn masa flour to contain 0.7 milligrams of folic acid per pound beginning January 1, 2026, with related label disclosures and specified exemptions; wet masa fortification is authorized rather than universally required [27]. Observers expect California's rule to influence national practice [28]. Major producers have moved ahead of the rules — Mission/Gruma reports roughly 97% of its U.S. retail portfolio is already fortified [5]. Large manufacturers may standardize national formulations rather than maintain a California-only line, while smaller firms bear proportionally higher testing, formulation, and label-change costs.
• Labeling and standards (nutrition facts, ingredient and allergen labeling, any "gluten-free"/"grain-free" claims) apply as to any packaged food.

Regulatory burden is moderate and mostly a compliance cost, not a barrier — but the spreading fortification mandates are a real, if small, cost and formulation item to watch.

8. Competitive dynamics and consolidation

The structure is a concentrated leader plus a fragmented tail. Gruma's Mission brand alone has led the U.S. hard/soft tortilla and taco-kit category with a share above 39% (52 weeks ended March 2022), and secondary estimates put Gruma's overall U.S. tortilla share around 44% [13][10]. Below the leader, no single competitor is close; Grupo Bimbo, Olé Mexican Foods, and a scatter of regional brands and private label divide the rest — consistent with the federal top-four share of 62.5% and top-50 share of 90% [11]. GRUMA characterizes the market as highly fragmented, regional, and extremely competitive, with numerous local producers [3].

Consolidation is running along two tracks:

1. Strategics buying "better-for-you" brands. The signal deal was PepsiCo's ~$1.2 billion acquisition of Siete Foods, the grain-free tortilla and Mexican-American brand, closed January 2025 [15]. Expect continued acquisition of fast-growing premium tortilla brands by large food companies.
2. Regional roll-ups. Family-owned and private-equity-backed regional producers (Olé, El Milagro, Flagship Food Group, and others) keep scaling and acquiring, chasing the distribution density that defines the category [10][18][20].

The competitive barriers are distribution (DSD networks, shelf space), plant density near demand, and — at the premium end — brand and formulation, more than any hard technology moat.

9. Risks

• Commodity/input volatility. Corn, wheat, cooking oil, energy, packaging, and freight costs move margins directly, and pricing power on plain product is limited by private label. Commodity hedging can delay volatility but cannot permanently remove it. Corn producers must additionally control mycotoxins, pesticide residues, unapproved genetically modified material, and other contaminants [21].
• Concentration and channel risk. With retail dominated by a few grocers and foodservice tied to a few chains, losing a major customer or a soft QSR (quick-service restaurant) cycle hits volume hard — as 2024–2025 foodservice weakness showed [3][13].
• Private-label and premium squeeze. Store brands compress the commodity core while premium entrants (often better-capitalized, post-acquisition) intensify competition at the profitable end.
• Perishability and logistics. Short shelf life and low value density require costly regional plant-and-DSD networks; a plant outage or recall is disruptive. Shelf life and service requirements make a distribution failure potentially more damaging than the loss of production for an equivalent period.
• Labor and distribution classification. Labor exposure includes plant staffing, maintenance skills, wage inflation, and turnover. Route systems create a separate classification risk where drivers or distributors are treated as independent contractors. GRUMA warns that reclassifying Mission's independent distributors as employees could produce additional costs and operational disruption [29].
• Regulatory drift. Expanding fortification mandates and labeling rules add cost and complexity, state by state [27][28].
• Substitution risk. Tortillas can take occasions from sliced bread and other flatbreads, but can lose occasions to bread, pitas, naan, lettuce wraps, rice bowls, taco shells, or restaurant menu changes. Health positioning is not assured: consumers may scrutinize sodium, refined flour, preservatives, emulsifiers, and processing even when a product is marketed as low-carbohydrate or high-fiber.
• For public investors specifically: the cleanest pure-play (Gruma) is a foreign-listed, currency-exposed (Mexican peso) multinational whose U.S. OTC ADR is thinly traded — access, liquidity, and FX are real frictions [17].

10. How to invest and the outlook

Public-market routes.

• Closest pure-play: Gruma (BMV: GRUMAB; U.S. OTC ADR GMKKY/GPAGF) — the category leader, but you buy a Mexico-listed multinational with peso exposure and a thin U.S. ADR [12][17].
• Diversified exposure: Grupo Bimbo (BMBOY), PepsiCo (PEP, now owner of Siete), Flowers Foods (FLO, owner of Papa Pita), or General Mills (GIS, Old El Paso) — for each, tortillas are a small piece of a large packaged-food business, so the "tortilla thesis" is diluted [14][15][16].

Private-market routes. This is where most of the industry actually lives: buying, building, or lending to regional manufacturers (Olé, El Milagro, La Tortilla Factory, contract/private-label plants) and premium better-for-you startups. Private equity is active in regional roll-ups — Flagship Food Group's investments in La Tortilla Factory and Tortilla King illustrate this route — and strategics are the natural exit buyers, as the Siete sale demonstrated [15][10][20]. A less direct approach is exposure to masa flour and grain suppliers, tortilla-line and packaging equipment, flexible packaging, cold or ambient distribution, or retailers with strong Hispanic-food private labels — though these should not be represented as exposure to NAICS 311830 itself.

Near-term drivers and outlook (forward-looking). The base case is a defensive staple with steady low-to-mid single-digit growth, tilting toward premium mix. We expect the strongest tailwinds to remain the health-forward and GLP-1-adjacent premium segments (grain-free, low-carb, high-protein), where pricing and margins are best, layered on top of a slow-growing commodity core and continued mainstream (non-Hispanic) adoption [10][1]. Near-term profitability will hinge on the grain and oil cost cycle and on foodservice recovery after 2024–2025's softness [3][13]. We anticipate consolidation to continue — large food companies acquiring high-growth tortilla brands, and regional producers rolling up — which is likely, over time, to create the scaled, more investable tortilla platforms that public markets currently lack. Spreading state-level fortification mandates are a modest cost headwind rather than a demand risk.
