Ice Manufacturing in the United States (NAICS 312113)

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

NAICS (North American Industry Classification System) code 312113 covers companies whose main business is making ice for sale — the 7-, 10-, and 20-pound bags of cubes you buy at a gas station or grocery store, plus block ice and bulk industrial ice sold to businesses.

1. Overview

Packaged ice is one of the oldest, least glamorous, and most local businesses in the food economy. The product is frozen water: cheap to make, expensive to move, and impossible to store for long. That single fact shapes everything about how the industry is structured and how owners make money.

Because ice is heavy, low-value, and melts, it can only travel a few hundred miles before freight and shrinkage eat the margin. So the industry is really a network of regional manufacturing-and-delivery routes, not a national factory business. Historically that produced a fragmented map of local operators. Over the last 25 years it has consolidated into a handful of large players with mostly non-overlapping territories — a trend that reached a milestone in February 2026 when the two largest producers combined.[1][2]

Why an investor cares. Demand is steady, weather-driven, and recession-resilient (people still buy ice for coolers and parties in a downturn), and the product is a near-commodity with pricing power at the point of sale. But it is highly seasonal and capital-intensive, and the industry carries a notable antitrust history.

Public vs. private ways in. There is essentially no pure-play public stock today — all three national producers are privately held by private-equity or family owners. Public-market investors get only indirect exposure (through PE sponsors' listed shares or through ice-equipment makers). The real action for direct investors is private: buying a regional ice company, or operating self-serve ice-vending machines. Both routes are covered in Sections 4 and 10.

2. What it is and how it's structured

In scope (312113): establishments primarily engaged in manufacturing ice — cube ice, crushed ice, block ice, and industrial/bulk ice — for sale to others. The industry sits within NAICS 312 (Beverage and Tobacco Product Manufacturing).[13]

What it excludes (important, because the federal data only counts the code above):

• Dry ice (solid carbon dioxide) — classified under NAICS 325120, Industrial Gas Manufacturing, not here.[13]
• Ice cream and frozen desserts — NAICS 311520.
• Self-serve ice-vending machine operators — when a company's business is running vending machines, Census counts it under NAICS 445132, Vending Machine Operators, i.e. retail, not manufacturing.[13]
• Captive ice — the enormous volume of ice made and consumed on-site by restaurants, bars, hotels, hospitals, supermarkets (their own in-store bagging), seafood/fishing operations, and food processors. That activity shows up in those industries' books, not in 312113.

How ice is made. Commercial plants filter or otherwise condition potable water, freeze it in plate or tube machines, harvest cubes or tubes, size or crush the product, bag it automatically, place it in frozen storage, and deliver it in refrigerated or insulated vehicles. In plate machines, water cascades over refrigerated vertical stainless-steel plates; in tube machines, water circulates through tubes and frozen cylinders are released with warm refrigerant. Industrial equipment can produce from roughly 1 to 125 tons per day, depending on configuration.[14][15]

Ownership mix. The sellable-ice business splits into three layers: (1) a few large, private, multi-region producers (Reddy Ice, now including Arctic Glacier; and family-owned Home City Ice); (2) hundreds of small independent local ice companies; and (3) a fast-growing fringe of self-serve ice-vending operators (Twice the Ice, Ice House America, Everest, Kooler Ice), often owner-operated as a passive-income sideline.[2][7][12]

3. How big it is

Our ground-truth federal figures for NAICS 312113:

Two things jump out. First, it's a small industry by headcount — about 5,400 direct manufacturing employees nationally and roughly $1.2 billion in merchant receipts. (An independent market estimate puts "Ice Manufacturing in the US" at about $1.3 billion for 2025, consistent with the Census receipts.[1]) Average pay works out to roughly $61,000 per worker (annual payroll ÷ employees). CBP = County Business Patterns; SBA = U.S. Small Business Administration; HHI and the CR ratios measure market concentration (defined in Section 8).

Second, the numbers scream seasonality. First-quarter (winter) payroll of $58.4 million annualizes to about $233 million — well below the actual $328 million annual payroll. The gap is the summer labor surge: producers staff up heavily for the May–September selling season and shed hours in winter. The FDA estimates that the average American purchases four bags of ice annually and that 80% of packaged-ice purchases occur between Memorial Day and Labor Day.[9]

The undercount caveat — real, and large. The 312113 line captures only firms that sell ice as their primary product. It misses the captive ice made in-house across food service, hospitality, health care, and fishing; it misses the self-serve ice-vending segment (counted as retail under NAICS 445132); and it misses the smallest local operators. The total money the U.S. economy spends producing ice is therefore materially larger than the ~$1.2 billion "manufacturing" figure — that figure is best read as the size of the merchant packaged-ice market, not of ice-making overall.

4. The investable universe

There is no listed pure-play packaged-ice company. The producers are private:

Public-market proxies (indirect only). Because the producers are private, listed exposure is thin and secondhand:

• Carlyle (Nasdaq: CG) owned Arctic Glacier until it sold to Reddy Ice in February 2026 — so that exposure has now ended.[5]
• Ice-equipment makers, which sell to (and compete with) the industry rather than producing ice: Hoshizaki (Tokyo: 6465), the world's largest commercial ice-machine maker; The Middleby Corporation (Nasdaq: MIDD); Pentair (NYSE: PNR), which acquired Manitowoc Ice for $1.6 billion in 2022 and has an installed base of approximately 1 million units; and Berkshire Hathaway (NYSE: BRK.B), whose Marmon/Cornelius unit makes ice and beverage equipment.[18][19]

The practical takeaway: public investors cannot buy the ice business directly; private investors can, and that is where nearly all the ownership sits.

5. How the money works

Ice economics are unusual and worth understanding.

Cheap to make, costly to deliver. Raw inputs — water, electricity, and plastic packaging — are a small share of the sale price. The cost and the margin live in logistics. A bag of ice must stay frozen from plant to store freezer, so producers run direct-store-delivery (DSD) route networks: company trucks restock retailers, often into company-owned merchandiser freezers placed inside the store (frequently on consignment, so the producer owns the ice until it sells). Freight, fuel, driver labor, and freezer capital — not water — are the real cost drivers. The DOJ notes that freight is unusually burdensome because ice is heavy and bulky relative to its selling price and because transport requires both fuel and refrigeration.[16]

Cost structure. Historical public filings from Reddy Ice (2011, before its restructuring) show labor as the largest expense at approximately 33% of revenue, followed by fuel at approximately 6%, plastic bags at approximately 6%, and electricity at approximately 5%. Those percentages are dated and company-specific, but the cost categories remain structurally relevant: driver wages and overtime, diesel, polyethylene bag prices (which track petrochemical inputs), and power for freezing and storage.[20]

Why the industry is regional. Because shipping frozen water is expensive and every mile adds melt/shrinkage, economic delivery radius is limited (roughly a few hundred miles). That is why national "producers" are really collections of regional route clusters, and why the big companies historically had complementary, non-overlapping footprints — a point the U.S. Department of Justice (DOJ) leaned on when it reviewed the 2026 merger. Route density, proximity to customers, backup capacity, and the ability to respond during a hot weekend matter more than national brand advertising.[2][16]

Seasonality is the swing factor. More than half of annual volume and profit is earned in the summer (Memorial Day to Labor Day). A hot, dry summer is a boom; a cool, wet one is a bust. Fixed costs (plants, freezers, trucks) are spread over a short selling season, which is why net margins are thinner than the low input cost would suggest, and why weather is the single biggest year-to-year revenue variable. The same historical Reddy Ice filings show roughly 71% of revenue occurring in the second and third quarters, with losses or materially lower margins in winter.[20]

Where the revenue comes from. Bagged retail ice sold through grocery, convenience stores, and gas stations is the core. On top of that: bulk/industrial ice to construction (concrete cooling), seafood and food processing, festivals and events, and emergency/disaster demand — hurricanes and grid outages produce sharp, high-price ice spikes, historically with the Federal Emergency Management Agency (FEMA) as a large episodic buyer. Producers also serve airlines and airline caterers, a channel the DOJ specifically flagged in the merger review.[2]

The economics to watch, industry-by-industry style: capacity utilization across a short season; weather-driven volume; input costs (electricity, diesel, plastic resin); DSD route density and freight cost per bag; and in-store freezer placement, which is the real competitive moat.

6. What drives demand

• Temperature and weather — the dominant driver. Hot summers, droughts, and heat waves lift volume; mild summers depress it. Extreme heat is not automatically more profitable: it can require overtime, third-party purchases, and long-distance transfers that erode margins. (Forward-looking: gradual climate warming is a mild volume tailwind, though it also raises energy and cooling costs.)[20]
• Outdoor and travel activity — camping, boating, tailgating, festivals, cookouts, and summer road-trip convenience-store traffic.
• Retail foot traffic — grocery and gas-station/convenience volume, where most bagged ice is sold on impulse.
• Industrial and commercial use — construction (concrete), seafood and food processing, catering and events.
• Disaster response — hurricanes, floods, and power outages create sudden, high-margin demand spikes, though they can also disrupt routes and add emergency logistics expense.

7. Regulation

Ice is legally a food, which puts it under the U.S. Food and Drug Administration (FDA). Packaged ice must be produced under the FDA's current Good Manufacturing Practices (cGMP) for human food: safe/sanitary water, clean equipment, employee hygiene, and proper handling, storage, and transport. Source water must be safe, and labels must state the responsible business and net quantity. Intrastate retail producers and foodservice establishments are generally overseen by state and local authorities rather than inspected by FDA, creating uneven enforcement.[9]

Beyond that federal baseline, the industry largely self-regulates. The International Packaged Ice Association (IPIA) created the Packaged Ice Quality Control Standards (PIQCS) in 1998 because no ice-specific federal or state rules existed. PIQCS is built on FDA GMPs but tailored to ice, and adds process control, recall procedures, pest control, food security, finished-product microbiological testing, and HACCP (Hazard Analysis and Critical Control Points). Since 2002 IPIA has required annual third-party PIQCS audits of member plants as a condition of accreditation.[8]

Industrial refrigeration safety. Most commercial ice plants use ammonia refrigeration systems. OSHA describes ammonia as corrosive to skin, eyes, and lungs and potentially flammable in enclosed concentrations. Its process-safety-management (PSM) requirements apply to systems holding 10,000 pounds or more of ammonia; smaller systems remain subject to general-duty, hazard-communication, and emergency-response obligations. Refrigerant leaks, aging piping, power failures, and deferred maintenance can produce both operational shutdowns and material liabilities.[21]

The other regulatory reality is antitrust. Given the industry's regional-monopoly tendencies and its history (Sections 8–9), mergers among ice producers draw active DOJ scrutiny — as the 2026 Reddy Ice / Arctic Glacier review showed.[2]

8. Competitive dynamics and consolidation

The defining trend is roll-up consolidation. Since Stone Canyon Industries (through its PE arm SCI Capital Partners) bought Reddy Ice in 2019, Reddy has made more than 20 acquisitions.[5] The capstone: in July 2025 Reddy Ice agreed to buy Arctic Glacier from Carlyle for more than $126.4 million (and less than $179.4 million), closing in February 2026.[3][4] That combined the two largest packaged-ice producers, leaving a national structure of essentially two large players — Reddy Ice/Arctic Glacier and Home City Ice — plus regional independents and the vending fringe.[2]

Regional footprints. The DOJ found that prior to the merger, the three scaled producers had largely complementary territories: Reddy was strongest in the South, Southeast, and parts of the West; Arctic Glacier in the Northeast, parts of the Midwest, and West Coast; and Home City in the Midwest plus parts of the Mid-Atlantic and Southeast. Small plants remain numerous, but DOJ found that most cannot credibly bid for multi-location chains or airlines because those customers require geographic coverage, backup capacity, and administrative simplicity.[16]

Concentration, measured. The federal data already showed a moderately concentrated industry before the merger: the four largest firms held 60.6% of receipts (the CR4 ratio), and the HHI (Herfindahl-Hirschman Index — the sum of each firm's squared market share; higher = more concentrated) stood at 1,274, in the "moderately concentrated" band. The 2026 merger pushes national concentration meaningfully higher.

Why the DOJ let it proceed — with conditions. Because Reddy and Arctic had mostly complementary territories, the DOJ required divestitures only where they actually overlapped: four facilities and customer contracts in Washington, Idaho, and California, plus customer contracts in Oregon and in the New York City and Boston metro areas, sold to smaller operators (including Columbia Basin Ice in Washington and Dee Zee Ice/"Diamond Ice" in the Northeast). The stated goal was to preserve competition for ice sold to retail chains, airlines, and airline caterers in those specific markets.[2][3]

Barriers to entry and the moat. Starting a single ice operation is cheap; building a regional DSD network with dense routes, cold storage, a refrigerated fleet, and thousands of placed in-store freezers is not. Incumbent freezer placement and retail relationships are the real barrier. The newer disruptor is self-serve ice vending, which strips out delivery labor and lets a machine convert water and electricity into $2–$3 bags on-site — a lower-capital, location-dependent model growing quickly at the industry's edges. Automation is also changing where manufacturing occurs: Reddy's approximately 2,320 in-store automatic bagging machines show that a producer can place manufacturing capacity at the retailer, avoiding some finished-ice freight while retaining the account and service relationship. However, DOJ found that in-store machines and vending are generally not viable substitutes for most large chains and airlines because of space, capacity, and cost constraints.[12][16]

9. Risks

• Weather/seasonality — the biggest revenue swing; one cool summer can wipe out a year's growth.
• Antitrust and legal history — this industry carries real baggage. In 2008–2010, producers pleaded guilty to federal charges of allocating customers and territories (a price-fixing-type scheme centered on Michigan). Home City Ice pleaded guilty in 2008; Arctic Glacier and several executives pleaded guilty and Arctic Glacier paid a $9 million criminal fine; the companies also settled sweeping civil class actions covering direct ice purchasers from 2001–2008. (Reddy Ice was investigated but was not criminally charged, having cooperated with the DOJ.) The current wave of consolidation keeps antitrust risk live.[10]
• Input-cost inflation — electricity (freezing is energy-intensive), diesel for the DSD fleet, and plastic-resin packaging prices all compress margins.
• Food-safety/recall risk — because ice is a regulated food, contamination can trigger recalls and reputational damage.
• Industrial refrigeration hazards — ammonia systems create worker-safety and environmental exposure; leaks, aging piping, and deferred maintenance can cause operational shutdowns and material liabilities.[21]
• Customer concentration and commoditization — large retail chains can squeeze pricing or push private label on a near-commodity product.
• Capital intensity + leverage — plants, cold storage, fleets, and in-store freezers are capital-heavy, and PE ownership tends to add debt. Reddy Ice's own history is a caution: after its 2005 NYSE IPO (ticker FRZ) it filed Chapter 11 in April 2012 under heavy debt and soft demand before being restructured and taken private.[11]
• Disruption from vending and in-store machines — self-serve machines and retailer self-production could erode the traditional bagged-and-delivered model in some markets.

10. How to invest, and the outlook

Public routes (limited). There is no direct listed ice producer. Investors wanting exposure must go indirect: through diversified PE sponsors' listed shares (e.g., Carlyle, Nasdaq: CG — though its Arctic Glacier stake ended in February 2026), or through ice-equipment makers such as Hoshizaki (Tokyo: 6465), Middleby (Nasdaq: MIDD), Pentair (NYSE: PNR, via Manitowoc Ice), or Berkshire Hathaway (NYSE: BRK.B, via Marmon/Cornelius). None of these is an ice-production play. Credit investors can occasionally access the sector through the leveraged-loan and high-yield bonds that finance the PE-owned producers.[5][18][19]

Private routes (where the ownership actually is):

1. Buy or operate a self-serve ice-vending machine or small route — the lowest-capital entry, marketed as passive income (Twice the Ice, Ice House America, Everest, Kooler Ice); returns hinge on location, foot traffic, and machine uptime.[12]
2. Acquire a local/regional ice company — the fragmented tail of hundreds of small operators is exactly the pipeline the national roll-ups feed on; a well-located regional network with retail freezer placements is a defensible, cash-generative asset.
3. Co-invest alongside the sponsors — Stone Canyon/SCI (Reddy Ice) and, historically, Carlyle and H.I.G. have run the platform strategy.

Key diligence considerations. Attractive targets are likely to have dense protected routes, durable chain accounts, redundant summer capacity, modern refrigeration, credible food-safety systems, and room to consolidate adjacent territories. Diligence should normalize earnings for weather, separate manufacturing from distribution economics, inspect ammonia systems and deferred maintenance, test customer-level profitability, and quantify the capital required to survive peak demand.

The outlook (forward-looking judgment). Expect continued consolidation, but capped by antitrust: a single national player can keep rolling up complementary territories, yet DOJ review will block or force divestitures wherever footprints overlap — so a true national monopoly is unlikely. Underlying demand is structurally flat-to-low-single-digit, tied to weather and summer activity, with warming summers a mild volume tailwind and energy/fuel costs a persistent headwind. The most interesting growth and disruption vector is self-serve vending, which lowers the labor cost of the model. And episodic disaster demand will remain a recurring, high-margin wildcard. For most investors this is a private-market, cash-flow-and-logistics business — not a stock — and it should be evaluated on route density, freezer placement, seasonal cost discipline, and weather exposure rather than on any market multiple.
