Packaging and Labeling Services (U.S.) — NAICS 56191

An investor's rollup primer. NAICS (North American Industry Classification System) code 56191 is a five-digit "industry" grouping. It contains exactly one six-digit industry — 561910, Packaging and Labeling Services — so this level is effectively identical to that single child. This page gives the level's own federal statistics and orients you; for the full analysis, read the 561910 primer.

1. Overview

NAICS 56191 covers firms whose main business is packaging, labeling, and imprinting goods their clients still own — the outsourced "last step" between a factory and a store shelf or shipping box. These firms are called contract packagers or co-packers: they supply labor, equipment, quality control, and floor space to pack client-owned products, rather than manufacturing products of their own [1].

Because this five-digit industry breaks down into just one six-digit industry, the two codes describe the same set of businesses and the same money. This page is a short rollup: it states the level's ground-truth figures and points you to the child primer for the detail on structure, economics, regulation, and how to invest.

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

The NAICS hierarchy narrows from broad sectors to specific industries. At the five-digit "industry" level, 56191 has a single six-digit "national industry" beneath it:

When a five-digit industry has only one child, the U.S. statistical agencies report identical definitions and (with rare rounding or vintage differences) identical numbers at both levels. There is no second child to blend in and no residual "all other" category. So everything true of 561910 — that it is a low-margin, labor-driven, highly fragmented service business with no publicly traded pure-play — is true of 56191 unchanged [1]. Read the 561910 primer for the full treatment.

3. Size (this level's rollup figures)

Federal statistics for NAICS 56191 (author's rounding of official figures; from our ground-truth file for this level):

These equal the 561910 figures, as expected for a single-child level. A few quick reads, using only figures from the same source and year: average revenue is roughly $6.3 million per firm (~$12.43B ÷ 1,964, Economic Census 2022), the average establishment has about 27 employees (52,301 ÷ 1,972, CBP 2023), and average pay is near $49,000 per worker (~$2.56B ÷ 52,301, CBP 2023) — the profile of a small-business, manual-labor industry [2][3].

Concentration is low. The four largest firms hold only about 20.1% of receipts, the top eight about 27.2%, the top 20 about 38.5%, and the top 50 about 52%; the Herfindahl-Hirschman Index (HHI, a standard 0–10,000 concentration gauge where under 1,500 is "unconcentrated") is just 147.6 — a genuinely fragmented industry [5].

Undercount caveat — read before quoting any market number. These are employer figures drawn from different years, so they should not be chained into a growth rate, and they understate total activity because small and individually owned operators dominate the long tail. County Business Patterns (CBP) and the Economic Census exclude non-employer (owner-operated) businesses, so the tiniest shops are missing from the ~$12.43B total [3][6]. Separately, the Census counts only establishments whose primary business is packaging client-owned goods; the same work done inside manufacturers, third-party-logistics (3PL) warehouses, and pharmaceutical contract packagers is coded elsewhere. That is why private market-research estimates for "U.S. contract packaging" run far higher — commonly $20–25 billion — because they use a broader definition [8][9]. Treat ~$12.43 billion as the narrow federal measure. Our ground-truth file reports no margin, capacity, capital-expenditure, or working-capital figure for this level; none is invented here.

4. Investable universe — where the value sits

Because 56191 is 561910, the investable picture is identical: there is no U.S.-listed pure-play contract packager. Public-market investors can get only diluted, indirect exposure through diversified proxies where co-packing is a minority of revenue — for example Sonoco (NYSE: SON) in packaging materials, Ryder (NYSE: R) and GXO Logistics (NYSE: GXO) in logistics, and Thermo Fisher (NYSE: TMO, Patheon) in regulated-pharma packaging [11][12][13][15]. The real pure-play activity is private and private-equity-owned — platforms such as PCI Pharma Services, Sharp Services, and MSI Express — plus thousands of regional independents [18][19][20]. Tickers, ownership tables, and caveats are laid out in Section 4 of the 561910 primer.

5. How the money works

Co-packers are service businesses: the client owns the goods and usually the packaging materials, so revenue is a fee for the work, not a markup on a product. Pricing is per-unit/per-piece, labor- or machine-hour, or project-based, with materials often passed through at a small handling margin. The margin levers are line utilization, changeover time, labor productivity, automation, and customer/program concentration. Regulated segments (pharmaceutical, cosmetics) earn better, stickier margins than commodity food-and-beverage co-packing. Full economics are in Section 5 of the 561910 primer.

6. Demand drivers

The same forces drive the whole level: brands outsourcing non-core packaging; new-product launches and stock-keeping-unit (SKU) proliferation; promotional and seasonal surge work; e-commerce and direct-to-consumer (DTC) shipping needs; private-label growth; and rising pharmaceutical and food-safety outsourcing. Food and pharma packaging is relatively defensive; promotional and discretionary work tracks consumer spending [8][9]. See Section 6 of the child primer.

7. Regulation

Regulatory burden is inherited from whatever product is packed. The heaviest driver is pharmaceuticals: drug packagers must run U.S. Food and Drug Administration (FDA) current Good Manufacturing Practice (cGMP) systems and comply with the Drug Supply Chain Security Act (DSCSA) serialization mandate [18][19]. Food, consumer-commodity labeling (the Fair Packaging and Labeling Act, FPLA), cosmetics (MoCRA), and workplace/transport rules also apply. Regulation acts as a moat — commodity co-packing is lightly regulated and price-competitive, while regulated segments reward compliance with stickier customers. Detail in Section 7 of the 561910 primer.

8. Consolidation

The federal data confirm a highly fragmented industry (top-four ~20% of receipts, HHI 147.6), and consolidation is the defining trend [5]. Private equity has been an active buyer, rolling regional shops into national platforms, with food-and-beverage and specialty-labeling especially active in 2024–2025 [20]. This is the central structural story for private investors; it does not yet show up as rising federal concentration. See Section 8 of the child primer.

9. Risks

Identical to 561910: labor scarcity and turnover; utilization sensitivity; customer concentration and in-sourcing; thin margins and cost pass-through timing; the capital intensity of automation; regulatory/quality failure (recalls) in food and pharma; discretionary-demand cyclicality; leverage risk under PE ownership; and measurement risk, since employer-only statistics understate the smallest operators. Full list in Section 9 of the 561910 primer.

10. How to invest & outlook

Public route (indirect, diluted): no listed pure-play exists; buy diversified proxies (Sonoco, Ryder, GXO, Thermo Fisher/Patheon, CCL Industries) and isolate the co-packing slice before applying any multiple [11][12][13][15][16]. Private route (direct): buy or build a regional co-packer (most qualify as small businesses under the U.S. Small Business Administration's $19.5 million average-receipts threshold [4]), co-invest alongside PE roll-ups, or back a compliance-heavy niche.

Outlook: structural tailwinds — brand outsourcing, e-commerce/DTC, private-label growth, and pharmaceutical serialization demand — are intact, with independent forecasters projecting mid-to-high single-digit annual growth for the broader contract-packaging market through the early 2030s [8][9][10]. But the business stays low-margin and labor-constrained, so value accrues to operators that automate, specialize, and consolidate rather than to generic commodity co-packers. Our ground-truth file for this level contains no growth, margin, or utilization estimate, so the industry must be underwritten company by company. For the complete analysis, read the 561910 primer.
