Petroleum and Petroleum Products Merchant Wholesalers (U.S.) — NAICS 4247

A rollup primer for public-market and private investors

What this page is. NAICS (North American Industry Classification System) code 4247 is a four-digit industry group — the level that sits just under "Merchant Wholesalers, Nondurable Goods." It bundles the two five-digit industries that move refined fuel from the refinery to the businesses that burn or resell it. This primer synthesizes the two child primers plus our ground-truth federal statistics for the group. Its job is the contrast between the two children — who is bigger, who is growing, who owns them, and how you would invest in each. For the deep dive on either half, follow the child primers (42471 and 42472); note that each of those is itself a single-child pass-through level, so the company-by-company detail ultimately lives one rung further down, at 424710 and 424720.

1. Overview

Every gallon of gasoline, diesel, jet fuel, heating oil, lubricant, and propane that leaves a U.S. refinery has to be stored, blended, financed, trucked, and handed off before anyone pumps it. NAICS 4247 is the wholesale middle of the fuel supply chain — the tank farms, loading racks, and fuel distributors that sit between the refinery and the gas station, the airport, the trucking fleet, the farm, and the home furnace [1].

It splits into two businesses that share a supply chain but earn money in very different ways:

• Petroleum bulk stations and terminals (42471) — the storage and handling half. Establishments with bulk liquid storage that wholesale crude and refined products, including liquefied petroleum gas: big tank farms that receive fuel by pipeline, ship, barge, or rail and load it into trucks (a fee/toll business), plus a long tail of small distributors that buy at the terminal and resell [1].
• Petroleum merchant wholesalers except bulk stations and terminals (42472) — the distribution half. Wholesalers and "jobbers" who move product without principally distributing out of their own large storage terminal, earning a few cents of margin per gallon on logistics and volume [1].

The boundary between them is a matter of facilities, not deal size: the Census questionnaire that populates these statistics defines a bulk terminal as a facility with at least 2.1 million gallons of storage (or a smaller one that receives product by tanker, barge, or pipeline), and everything smaller as a bulk station [4]. A 42472 wholesaler can still buy terminal throughput, exchange barrels, and arrange pipeline or marine movements — it simply does not run the tankage itself [1].

Why an investor cares: this is essential, high-volume, cash-generating plumbing for the U.S. economy — a "picks-and-shovels" way to own fuel demand without betting on the price of crude — facing one slow structural headwind (gasoline demand is plateauing) and consolidating steadily across both halves.

2. What's inside — the two children, and how they differ

The group has exactly two child industries. Both are large, both are mature, and both are commodity pass-throughs — but they differ in size, economics, ownership, and how you buy in. This contrast is the whole point of the page:

Read across the table and four things stand out. First, the terminal half is the bigger and more capital-intensive one — more of the sales, more of the establishments, and two-thirds of the workers. Second, the wholesale half is even more of a pass-through — its $24 million of sales per worker (versus $16 million for terminals) and a payroll equal to roughly half a percent of receipts [2][3] reflect that pure distributors hold almost no infrastructure and add the least value per dollar of fuel that flows through. Third, the two halves have almost identical firm counts (1,855 versus 1,826) but very different footprints per firm: the terminal side averages about two establishments per firm against roughly one and a third on the wholesale side [2][3] — multi-site networks versus single-yard operators. Fourth, ownership differs sharply: the terminal half has real listed and private-equity infrastructure you can buy as fee-based cash flow, while the wholesale half is overwhelmingly private and family-held, so most of it is invisible in public markets. Definitions — MLP (master limited partnership), HHI (Herfindahl-Hirschman Index), CR4 (share of receipts held by the four largest firms), C-corp (a regular taxable corporation), PE (private equity) — are expanded in Sections 3-10.

3. Size (this level's rollup figures)

Our ground-truth federal statistics for the whole group (stats-4247.md):

The children reconcile into these totals cleanly: establishments (3,747 + 2,466), employment (67,377 + 34,403), and payroll ($6.41B + $4.37B) each add up exactly to the group figure, and receipts sum to within a rounding error of $1.93 trillion [2][3]. Firm counts do not add (1,855 + 1,826 = 3,681 versus 3,491 for the group), because roughly 190 companies operate in both sub-industries and are counted once at the group level — a first clue that the two halves are run by overlapping operators.

Why that overlap matters more than it looks. NAICS classifies establishments, not companies, so a single integrated operator can run separately coded terminal, wholesale, trucking, and retail sites — and consolidated company revenue can never be read as market share in either code [1]. Global Partners is the clean illustration: the same partnership reports 54 terminals and 22.3 million barrels of storage (the 42471 side) alongside a wholesale segment that sold 5.883 billion gallons for $12.66 billion of sales and $321.7 million of product margin (the 42472 side) [8]. Both child primers cite that one company for opposite halves of the group. Read this level as two accounting buckets over one physical business, not two separate industries.

One number tells the group's story: receipts per employee are roughly $19 million — nearly $2 trillion of sales spread across only ~102,000 workers [2][3]. That is not extraordinary profitability; it is the signature of a commodity pass-through. Most of that "revenue" is simply the value of fuel moving through, not value the industry adds. Average pay is about $106,000 per worker across the group and about $95,000 on the terminal side [3] — a small, skilled, capital-supported workforce, not a labor-intensive trade. The U.S. Small Business Administration (SBA) sets the "small" threshold at 225 employees for 424710 and 200 for 424720 [5], a bar most of the ~3,491 firms clear.

Concentration — and a genuine rollup surprise. At the group level the four largest firms take 28.5% of receipts; the top 8, 45.1%; the top 20, 68.3%; the top 50, 83.4%; and the HHI is 338.1 [2]. That is less concentrated than either child on its own at every threshold — terminals run CR4 40.5% / CR8 57.4% / CR20 77.6% / CR50 88% with an HHI of 579.5, and wholesalers CR4 ~33% / CR8 ~54% / CR20 ~75% / CR50 ~87% with an HHI of ~455 [2]. The reason is instructive: the biggest terminal owners and the biggest non-terminal wholesalers are largely different companies, so pooling the two industries spreads receipts across more distinct large firms and the measured concentration falls. (The HHI sums the squared market shares; the two child primers quote slightly different antitrust reference points — roughly 1,500 for "concentrated" in one and roughly 1,800 for "highly concentrated" in the other — but on either convention 338 reads as very unconcentrated nationally.) The caveat both children share: fuel logistics is local — a terminal serves the trucks that can reach it in a day — so individual regional markets are far more concentrated than any national figure implies.

Undercount caveat (it matters here). Treat ~$1.93 trillion as one slice of U.S. fuel distribution, not the whole system. Two effects run in opposite directions. (1) The Census understates the physical footprint: integrated refiners (Marathon, Phillips 66, Valero, Chevron, ExxonMobil) own large captive terminal networks classified under their primary business — refining — not under 4247; government and military fuel terminals (the Defense Logistics Agency) are not counted as business establishments at all; and adjacent codes for retail fuel dealers (457210), gas stations (457110), and commission brokers (425120) hold activity that belongs to the same companies [1]. The U.S. Energy Information Administration (EIA) separately tracks roughly 1,400+ operable product terminals of 50,000 barrels or more [18], a count of infrastructure that overlaps with but does not map onto the Census establishment count. (2) The receipts figure overstates economic value-added, because it is mostly pass-through commodity cost. The industry is also heavily private and family-owned, so ownership is fragmented and hard to see fully in public data. The honest read: a real, roughly-$1.9-trillion merchant-wholesale slice, but "fuel distribution" as a whole is larger and messier than any one code shows.

4. Investable universe (where value concentrates across the children)

There is no pure-play "petroleum wholesaler" stock or index at any level of this group, and no dedicated exchange-traded fund (ETF). Listed exposure straddles wholesale, terminals, and retail, and it concentrates almost entirely in the terminal half (42471) — the wholesale half (42472) is where the big operators are private. Where value shows up publicly, by lane:

• Fee-based terminals (from 42471): ONEOK (OKE), Kinder Morgan (KMI), MPLX (MPLX), Plains All American (PAA/PAGP), Phillips 66 (PSX). Toll-like, contracted cash flow.
• Fuel distribution and marketing (spans both children): Sunoco (SUN), World Kinect (WKC), Global Partners (GLP), Delek Logistics (DKL), CrossAmerica (CAPL) — volume exposure.
• Propane (from 42471): UGI (UGI)/AmeriGas, Suburban Propane (SPH), Ferrellgas (FGPR, OTC) — winter-heating exposure.
• The closest listed pure distributor sits in 42472 as a single C-corporation (ordinary stock, no K-1), with a second corporate-form name offering retail-weighted exposure; the biggest wholesalers in the country, though, are private and family-held.
• Major private owners — often larger in pure terminal terms than the listed names: Buckeye Partners (IFM Investors), TransMontaigne (ArcLight Capital), refiner captive terminals, Pilot (majority-owned by Berkshire Hathaway), the farmer-owned cooperative CHS Inc., plus thousands of independent family jobbers across both children.

The capacity evidence now makes that last point concrete. On the listed side, ONEOK reports 53 refined-product terminals and 100 million barrels of operating storage in its Refined Products & Crude segment [10]; Kinder Morgan reports 47 liquids terminals at about 78.7 million barrels [11]; Sunoco, the largest U.S. motor-fuel distributor, operates 83 terminals globally, 53 of them in the continental U.S., after buying NuStar [12]. Privately held Buckeye reports more than 130 liquid-petroleum terminals and roughly 125 million barrels of tank capacity [13] — larger than any of the public networks above. These disclosures are scoped differently and are not strictly comparable, but the conclusion holds at the group level: a meaningful share of this group's physical capacity is not listed on an exchange at all.

The takeaway for an allocator: the buyable, income-producing infrastructure lives in the terminal child; the wholesale child is mostly a private-market game.

5. How the money works

Two engines share the group:

• Terminals — a fee/toll business. They generally do not own the fuel; they handle it for others, earning throughput fees per barrel, storage lease fees (often take-or-pay or minimum-volume contracts that pay whether or not the space is used), and blending/loading fees [14]. Kinder Morgan reports that its liquids terminals generally run on long-term contracts under which customers pay whether or not they use the capacity, with a weighted-average remaining term of about two years at year-end 2025 [11], and ONEOK described roughly 90% of its Refined Products and Crude segment earnings as fee-based in its 2025 outlook [10]. The result is stable, often inflation-linked, contracted cash flow — the "toll road" quality investors prize. A periodic bonus rather than a base case: when oil futures move into contango (future prices above today's), traders bid up storage and lease rates spike, as they did in 2020 [14].
• Wholesalers and jobbers — a cents-per-gallon business. They do buy fuel at the terminal "rack" price and resell it delivered, earning a thin spread — roughly 3–4% of revenue for independent bulk stations [6], or about 3–6 cents per gallon as the distribution trade measures it [7]. Real disclosures show wide dispersion around that rule, which is why per-gallon margins are not comparable across business models: Global Partners' wholesale segment earned about 5.5 cents per gallon of product margin on 5.883 billion gallons [8], while CrossAmerica's wholesale operation averaged 9.1 cents per gallon on 688.7 million gallons — a figure that includes rental income from fuel-site real estate [9]. Fuel price itself is largely a pass-through; the money is in logistics — reliable supply, truck-fleet density, customer credit, fuel-tax collection, and higher-margin add-ons (lubricants, cardlock fleet fueling, propane, heating-oil service). Rising prices swell working-capital needs and swing margins quickly, so interest rates hit the balance sheet hard, and hedging leaves residual basis and timing risk.

The metrics that matter differ from an oil trade: gallons sold, margin per gallon, segment EBITDA (earnings before interest, taxes, depreciation, and amortization), and — for the MLPs — distribution coverage — not crude-price forecasts. On the private side, underwriting turns on verified gallons and gross profit by product and customer, margin stability through the cycle, counterparty concentration, and working capital under stressed fuel prices, with inventory gains stripped out of normalized EBITDA. A structural detail links the two halves: federal and most state motor-fuel excise taxes attach at the terminal rack under Internal Revenue Code §4081, making terminals and "position holders" the government's tax-collection point [15] — one reason the whole group is tightly licensed.

6. Demand drivers

• U.S. refined-product consumption — roughly 20.6 million barrels per day in 2025 [16], of which motor gasoline was about 8.9 million bpd [16]. Volumes track miles driven, freight activity, air and shipping traffic, industrial output, and winter weather.
• Price volatility — feeds storage and trading economics for terminals and whipsaws jobbers' margins and working capital [14].
• Fuel-blending mandates — the federal Renewable Fuel Standard (RFS) and state low-carbon programs add fee-earning ethanol/biodiesel blending at terminals. EPA's final standards set total applicable volumes of 26.81 billion RINs for 2026 and 27.02 billion for 2027 [19], work that lands physically at the rack.
• The structural swing factor: gasoline is plateauing. EIA reports 2025 gasoline consumption down about 1% from 2024 and 4% from 2019, as a 1.9% improvement in implied fleet fuel economy outran a 1.2% rise in miles driven [16], and projects a further ~1% decline in 2026 with declines continuing into 2027 [17], and long-run transportation-fuel demand falling for decades [17]. Diesel, jet, renewable diesel, and sustainable aviation fuel (SAF) are more durable — which is why operators on the terminal side are repurposing gasoline tanks toward them. Renewable fuels cut both ways: renewable diesel displaces petroleum diesel volumes even as blending and credit management create new margin for marketers who can handle them.
• Exports (a terminal-side divergence). U.S. gasoline, diesel, and jet-fuel exports averaged 2.4 million bpd in 2025, including 902,000 bpd of gasoline [18]. Export-capable Gulf Coast terminals therefore face a materially better demand path than inland gasoline racks — a reminder that assets inside this group are not interchangeable, even within one code.

7. Regulation

The group is lightly regulated on entry but heavily regulated on product, safety, tax, and environment. On the terminal side (42471): the U.S. Environmental Protection Agency's (EPA) Spill Prevention, Control, and Countermeasure (SPCC) rule, which bites at 1,320 gallons of aggregate aboveground oil storage and requires a Professional-Engineer-certified plan above 10,000 gallons plus secondary containment sized for the largest tank [20]; tank-integrity standards (API 653, NFPA 30); Clean Air Act vapor-recovery limits on loading racks; underground-storage-tank (UST) programs; and Pipeline and Hazardous Materials Safety Administration / Department of Transportation (PHMSA/DOT) hazmat rules for pipeline, truck, and rail movement. On the wholesale side (42472): multi-state motor-fuel excise-tax collection and remittance; the RFS and its Renewable Identification Numbers (RINs); fuel-quality specs such as ultra-low-sulfur diesel (ULSD); hazmat-endorsed commercial driver's licences that constrain the hiring pool [22]; and low-carbon-fuel programs such as California's Low Carbon Fuel Standard (LCFS) and its Oregon and Washington analogues, which require registration, quarterly reporting, and credit settlement [23]. Costs are still ratcheting up on both sides: EPA's 2024 gasoline-distribution rules tightened storage-tank, loading, vapor-collection, leak, and monitoring requirements at an estimated $75.8 million of industry capital cost (2021 dollars) [21]. The practical effect across both children: compliance is a real fixed cost and a barrier to entry, and environmental liability is the group's defining risk.

8. Consolidation

Consolidation is the dominant theme across both children, and the pressure now comes from three directions rather than one. Among large terminal/midstream operators, mega-deals include ONEOK's ~$18.8 billion acquisition of Magellan Midstream, closed September 2023 [24], and Sunoco's ~$7.3 billion acquisition of NuStar (~9,500 miles of pipeline and 63 terminal/storage facilities), closed May 2024 [25], with Sunoco's 2025 acquisition of Parkland the largest recent addition [26]. Infrastructure private equity has become a major owner class, drawn by toll-like cash flows: IFM Investors took Buckeye Partners private in 2019 at roughly $10.3 billion of enterprise value [27], and ArcLight owns TransMontaigne. Meanwhile the majors are squeezing the base from above, cutting their branded-distributor rosters sharply in favour of larger partners — ExxonMobil to roughly 50, Shell and Chevron to about 100 each, down from hundreds [28]. Beneath all of it, the fragmented tier of thousands of family jobbers in both codes is rolling up steadily, driven by aging owners, succession gaps, tank-upgrade and compliance costs, and renewable-fuel (RIN) accounting complexity, with Sunoco, World Kinect, Global Partners, Pilot, and PE-backed platforms doing the buying; propane follows the same pattern. Moats are mostly locational, plus contracts, permits, and switching costs, and incremental barrels reuse the same site, control room, rack, and compliance overhead. The group HHI of 338 will drift up over time, but from a very low base — this is scale-building, not monopolization.

9. Risks

• Structural demand decline in gasoline as efficiency and EVs advance [16][17]; the offset is diesel, jet, and renewable fuels.
• Commodity-price volatility whipsaws jobber margins and makes terminal storage value feast-or-famine [14]; price spikes inflate inventory and receivable financing, price falls create write-downs, and hedges can fail through basis or timing mismatch.
• Environmental liability — spills, leaks, and legacy-site remediation: large, long-tailed, expensive, and often surviving a change in ownership, which makes diligence decisive in a sector this acquisitive.
• Regulatory/compliance escalation raising fixed costs across both halves [21].
• Capital and interest-rate sensitivity — terminals are capital-intensive; MLPs carry leverage, pay out most cash flow, and can cut distributions; jobbers' inventory financing is rate-sensitive.
• Labor — a shortage of qualified tank and hazardous-material drivers raises freight cost and can prevent service at peak [22].
• Weather — warm winters cut heating-oil and propane demand; hurricanes, flooding, and freezes disrupt Gulf Coast operations.
• Safety and security — fire/explosion catastrophe risk, and cyber risk to control systems (the 2021 Colonial Pipeline shutdown is the cautionary tale).
• Customer/supplier concentration — regional operators in either child can lean heavily on a few refiners or large accounts; a refinery closure or contract roll-off is a real single-asset risk.

10. How to invest, and the outlook

Public routes (concentrated in the terminal child). Buy the diversified midstream MLPs and corporations from Section 4 — fee-based terminal names (OKE, KMI, MPLX, PAA/PAGP, PSX) for lower commodity risk, distribution/marketing names (SUN, WKC, GLP, DKL) for volume exposure, and propane (UGI, SPH) for winter heating. A tax note: MLP units generate a Schedule K-1 tax form and often pay high distributions (and can create unrelated business taxable income, or UBTI, inside retirement accounts); C-corps issue an ordinary 1099. Match the wrapper to your account, and look at distribution coverage and leverage rather than headline yield. There is no pure petroleum-wholesaler ETF, though diversified midstream/MLP ETFs hold several of these names.

Private routes (where the wholesale child mostly lives). This is where "pure" fuel-distribution investing happens — buy or build a jobber or propane business (fragmented, cash-generative, roll-up-friendly, priced on EBITDA multiples and gallons), take a branded distributorship under a refiner's flag or a cooperative membership for agricultural supply, or invest through the infrastructure private-equity funds that own terminal networks.

Outlook. The two halves diverge. The fee-based terminal core (42471) should stay resilient — contracted, toll-like, often inflation-linked cash flow, plus a genuine tailwind as tanks are repurposed for renewable diesel, SAF, and ethanol, and an export bid that favours coastal assets over inland racks [18]. The wholesale/jobber tier (42472, and the jobber tail of 42471) faces thinner, more cyclical economics and a shrinking gasoline pool, but consolidation, logistics density, and diversification beyond gasoline — diesel, aviation and marine fuel, lubricants, renewable fuels, convenience retail — are the proven ways operators grow earnings against flat-to-declining volume. Net for the group: a mature, essential, consolidating infrastructure sector — best understood as an income-and-consolidation story, not a growth-commodity bet — with steady cash today, managed decline in gasoline exposure, and optionality in the shift to lower-carbon fuels. For the company-by-company detail on either half, see the child primers.
