HUNTSMAN CORPORATION · NYSE: HUN · PUBLIC COMPANY BRIEF · 15 SEP 2026

The specialty chemicals maker behind the foam you never see.

Huntsman's most concrete material-transition lane is already tied to a product and process: Huntsman Building Solutions describes polyurethane insulation made by transforming low-quality PET bottles, while TPU sites in Jinshan and Osnabrück have secured ISCC+ certification for traceable recycled or bio-based inputs. The next decision is a named grade, site and customer qualification record.

Ticker / CIKNYSE: HUN · SEC CIK 0001307954

FY2025 revenue & cost proxy$5.68B revenue, $4.93B reported cost proxy, period ended 31 Dec 2025 (SEC XBRL)

Business modelSpecialty and intermediate chemicals across three segments: Polyurethanes (MDI-based), Performance Products (amines, surfactants, maleic anhydride), and Advanced Materials (epoxy, acrylic and polyurethane-based formulations)

Public plant signal13 U.S. facilities matched to a Huntsman parent name in the 2024 TRI dataset; the Port Neches, TX olefins/intermediates site is the top-volume named lead

Decision entryA named site, product line, and formulation decision is the workable starting point. Huntsman’s MDI, amines, and epoxy businesses each have distinct feedstocks, customers, and regulatory profiles

What the public record tells us

Concentration signal: Huntsman is one of a small number of global producers of MDI (methylene diphenyl diisocyanate), the core input to polyurethane rigid and flexible foam. That concentration is a genuine structural fact worth naming: a material-transition conversation about polyurethane foam recyclability or bio-based polyol substitution sits on top of a market with few alternate suppliers, not a commodity swap.

Portfolio-simplification signal: Huntsman divested its Textile Effects segment (textile dyes and chemicals) to Archroma in a transaction announced in 2023, narrowing the company to three segments. Confirm current transaction status and any residual retained liabilities in Huntsman’s own filings before treating this as fully closed.

Waste signal, with a caveat: Matched 2024 TRI records show 157.9M lb of listed chemicals managed nationally, concentrated at the Port Neches, TX facility (ethylene, top-reported chemical). Component TRI management-category figures reported below do not sum exactly to the published total, a rounding and categorization artifact consistent across TRI aggregates in this dataset, not a Huntsman-specific discrepancy.

Regulatory and certification signals

How to use this viewFull detail sits in the Regulatory tab: connect each requirement to a named site before treating it as applicable

Innovation and recovery signals

Material innovationBio-based and lower-carbon-intensity polyol and surfactant R&D across Performance Products and Polyurethanes; MDI-based rigid foam is itself a building-efficiency material

Recovery pathwaysPolyurethane foam mechanical and chemical recycling is an active industry-wide R&D area; Huntsman-specific commercialized recycling volumes are not confirmed in this source set

Commercial lensMatch segment, site, and formulation separately. Polyurethanes, Performance Products, and Advanced Materials each sell into different end markets with different substitution economics

Three segments, one feedstock backbone

Huntsman’s public segment structure is the clearest lens on where a material-transition conversation should start. Each segment has its own customers, feedstocks, and substitution economics; treating Huntsman as one undifferentiated “chemicals company” loses the detail a real decision needs.

Company reported, segment structure

Polyurethanes: the MDI franchise

Huntsman’s largest segment by revenue produces MDI (methylene diphenyl diisocyanate) and polyols, the core chemistry behind rigid and flexible polyurethane foam. MDI-based rigid foam insulation, spray foam, and composite wood panels are genuine building-efficiency and lightweighting materials in their own right; flexible foam serves furniture, bedding, and automotive seating. Huntsman is one of a small number of global MDI producers, a genuine market-concentration fact, not a hypothesis, that should shape how a substitution or recycled-content conversation is framed: this is closer to a supply-security and process-chemistry conversation than a commodity-swap conversation.

Performance Products: amines, surfactants & maleic anhydride

This segment supplies specialty amines (used in coatings, oilfield chemicals, and epoxy curing agents), surfactants (personal care, agriculture, and industrial applications), and maleic anhydride (unsaturated polyester resins, lubricant additives). It is the segment most directly adjacent to formulation-level substitution work: bio-based surfactant chemistry and lower-toxicity amine curing agents are active, publicly discussed industry R&D directions.

Advanced Materials: epoxy & high-performance formulations

Epoxy, acrylic, and polyurethane-based resin systems for aerospace composites, wind-turbine blades, electronics encapsulation, and industrial coatings and adhesives. This is Huntsman’s highest-specification, lowest-volume segment, and the one most likely to already run under customer-qualified, spec-driven substitution processes rather than open-market commodity purchasing.

Textile Effects divestiture

Huntsman announced the sale of its Textile Effects segment (textile dyes, chemicals, and digital inks) to Switzerland-based Archroma in 2023, narrowing the company’s reporting structure to the three segments above. This brief treats Textile Effects as divested and out of scope; confirm final closing terms, timing, and any retained environmental liabilities in Huntsman’s own current filings before relying on this for a live conversation.

Materials entering the system

Huntsman does not publicly itemize feedstock volumes by segment or site in this source set. The table below maps directional material families to each segment’s known chemistry, using TRI and segment disclosure as the anchor points.

Directional, public category signal

Material family	Public signal	Transition lens
Benzene, propylene & aniline-chain feedstocks	Public category signal	Not publicly itemized by volume at parent level; MDI production runs on an aniline/phosgene-chain process, a genuine structural fact worth naming to a counterparty
Ethylene & olefins (Port Neches, TX)	TRI top-chemical match	Top-reported TRI chemical by managed weight at Huntsman’s highest-volume matched facility
Specialty amine & surfactant precursors	Public category signal	Feedstock for Performance Products segment; bio-based precursor substitution is an active but unconfirmed-at-Huntsman R&D direction
Epoxy resin precursors (bisphenol-A chain, etc.)	Public category signal	Feedstock for Advanced Materials; customer-qualified specifications limit substitution speed

Financial scale context

$5.68B FY2025 revenue and a $4.93B reported cost proxy (period ended 31 Dec 2025, SEC XBRL) provide scale context for Huntsman’s total raw-material and operating cost base. Neither figure is broken out by feedstock, segment, or site, and Huntsman does not publicly itemize aniline, benzene, or olefin purchase volumes in this source set.

Material transition focus

The practical entry point is segment-specific: bio-based polyol content or foam-recycling infrastructure for Polyurethanes, safer or bio-based surfactant and amine chemistry for Performance Products, and recycled-content or lower-embodied-carbon resin systems for Advanced Materials, each evaluated at the named site and product-line level.

Reported residual & listed-chemical signals

2024 TRI data gives a facility-level, U.S.-only view of Huntsman’s listed-chemical reporting, concentrated at the Port Neches, TX olefins and intermediates site.

Parent-name TRI match

Top named U.S. TRI facility lead (parent-name match, unresolved)

Facility	TRI ID	Top chemical	Note	Status
Huntsman Petrochemical LLC, Port Neches, TX	77651TXCCHHWY36	Ethylene	Top-reported facility lead	Unknown until validated

This is a candidate facility lead from parent-name matching against 2024 U.S. TRI records, excluded from any owned/operated plant count until ownership and operating control are verified, the same caution applied to every company brief in this universe.

National TRI footprint (2024, aggregate across 13 matched facilities)

Facilities matched to Huntsman parent name13

Total listed chemicals reported (aggregate)157,884,491 lb

Recycled on- or off-site (aggregate)1,590,067 lb

Treated (aggregate)24,191,703 lb

Energy recovery (aggregate)123,067,469 lb

On-site release (aggregate)7,522,186 lb

Off-site transfer (aggregate)1,566,910 lb

PFAS-listed forms reported0

Components (1.59M + 24.19M + 123.07M + 7.52M + 1.57M lb ≈ 157.94M lb) run slightly above the published 157.88M lb total, an EPA rounding and categorization artifact seen across every TRI aggregate in this dataset, not evidence of an error specific to Huntsman. Energy recovery is the dominant management category by weight, consistent with a large-volume organic-chemical intermediates site.

Process-chemistry signal

Energy recovery dominating the 2024 TRI aggregate is consistent with a petrochemical intermediates site combusting process off-gas and waste organics for heat recovery, a common practice at large olefins and MDI-chain facilities. This is a directional read of the aggregate shape, not a site-specific process confirmation.

PFAS & hazardous-air-pollutant context

Zero PFAS-listed forms are reported in the matched 2024 TRI records. Huntsman’s organic-chemical manufacturing sites remain subject to Clean Air Act HON/MON hazardous-air-pollutant standards independent of PFAS status; see the Regulatory tab.

Scope limitation

TRI parent-name matching only reaches U.S. facilities filed under a Huntsman corporate name and only covers the specific listed chemicals tracked in this source set. It is not a complete emissions or waste inventory for Huntsman’s full global footprint, and it says nothing about operations outside the United States, where the majority of Huntsman’s Advanced Materials and a meaningful share of Polyurethanes capacity sits.

Highest-leverage public opportunities

Each hypothesis connects a public TRI, segment, or feedstock signal to a specific transition pathway, ranked by fit given Huntsman’s three-segment specialty-chemicals model.

Bio-based & recycled-content polyol substitution

Screening candidate

Polyurethanes is Huntsman’s largest segment; bio-based or recycled-content polyol formulations for rigid and flexible foam are a genuine, customer-facing sustainability lever without displacing the core MDI chemistry.

Named foam-system product line
Bio-based or recycled-content polyol specification
Fire-performance and mechanical-property equivalence data

Polyurethane foam-to-foam recycling offtake

Qualification open

Chemical and mechanical polyurethane recycling technologies are an active, publicly discussed industry R&D area. A named commercialized Huntsman recycling volume is not confirmed in this source set, making this a build-from-zero opportunity rather than a scale-up.

Named recycling technology partner
Feedstock foam-waste stream and volume
Product-quality specification for recycled-content MDI/polyol output

Safer & bio-based surfactant chemistry

Qualification open

Performance Products’ surfactant lines serve personal care and agriculture end markets where bio-based and lower-toxicity formulation trends are commercially active.

Named surfactant product line
Bio-based precursor supplier qualification
Regulatory and label-claim fit

Lower-embodied-carbon epoxy & resin systems

Qualification open

Advanced Materials’ aerospace and wind-energy customers increasingly specify lower-embodied-carbon resin systems; this is a spec-driven, longer-cycle opportunity distinct from the other two segments’ faster-moving formulation work.

Named resin system and end customer
Lower-carbon precursor qualification
Aerospace or turbine-blade specification fit

Priority opportunity

Start inside one segment, with a named product line and formulation decision, not the enterprise logo. Huntsman’s three segments have different customers, feedstocks, and decision owners; a single enterprise-wide pitch will not reach the business-unit R&D or product-stewardship owner who actually controls a formulation change. Recommendation: pilot after evidence closure. Name one segment, one product line, and one formulation decision before proceeding.

Regulatory watchlist, certifications & innovation signals

Huntsman’s dominant U.S. regulatory throughline is TSCA chemical review and Clean Air Act air-toxics control for organic-chemical manufacturing, alongside TRI listed-chemical reporting; REACH is the parallel European framework given Huntsman’s global footprint.

Jurisdiction	Framework	Trigger / status
United States (federal)	TSCA new-chemical & existing-chemical review (EPA)	Applies to new chemical substances and select existing-chemical risk evaluations across Huntsman’s intermediate and specialty product lines
United States (federal)	Clean Air Act: HON/MON organic hazardous air pollutant standards	Air-toxics control requirements applicable to organic-chemical manufacturing sites such as Port Neches, TX
United States (federal)	TRI (Toxics Release Inventory)	Facility-level listed-chemical release and management reporting for matched U.S. sites
European Union	REACH registration & restriction	Applicable to Huntsman’s European manufacturing and product-registration footprint; site- and substance-specific status not in this source set

Regulatory applicability has not been adjudicated per site here. This is a watchlist, not a legal conclusion.

Certification & reporting families in play

Source boundary

Scope: public company, SEC, and 2024 TRI sources, read against Huntsman’s three-segment specialty-chemicals structure. FY2025 revenue and cost proxy are SEC XBRL sourced; TRI is a facility-level U.S. view against a 13-facility national aggregate; the Textile Effects divestiture is treated as announced/closing per 2023 public disclosure and should be confirmed current; and every opportunity is a directional hypothesis pending segment- and site-level evidence.
