Dichloromethane (CAS 75-09-2), universally known as DCM or methylene chloride, is a volatile, non-flammable chlorinated solvent with the molecular formula CH₂Cl₂ and a molecular weight of 84.93 g/mol. It is a clear, colourless liquid with a chloroform-like sweet odour, a boiling point of 39.6 °C, a vapour pressure of 435 mmHg at 20 °C, and a density of 1.33 g/cm³. Its commercial identity rests on a property profile that is difficult to replicate among non-flammable solvents: DCM combines high solvency power for a broad range of resins, polymers, oils and pharmaceutical actives with rapid evaporation and a non-flammable classification that simplifies handling in processes where ignition sources cannot be fully excluded. That combination made DCM the reference solvent for pharmaceutical processing, film coating, electronics cleaning, aerosol propellant formulations and urethane foam blowing, and it remains a critical processing aid in API manufacturing where its rapid and complete removal supports ICH Q3C residual-solvent compliance.
But DCM’s regulatory identity is more contested than its technical utility. In the United States, the EPA’s May 2024 TSCA risk management rule prohibited most industrial and commercial uses and imposed stringent workplace protection requirements on the remainder. Then, on 15 September 2026, the U.S. Court of Appeals for the Fifth Circuit vacated the 2024 rule and the underlying unreasonable-risk determination in East Fork Enterprises, Inc. v. EPA, holding that EPA may not make a “whole chemical” determination and must account for PPE where the record shows it is actually or foreseeably used. That decision has thrown the U.S. regulatory pathway into a period of legal and administrative uncertainty. In the EU, DCM is not a SVHC and not subject to Annex XIV authorisation, but it is restricted under REACH Annex XVII entry 59, which since 2010 has prohibited the supply of DCM-based paint strippers to the general public and to professionals in certain applications. The global market reflects this tension between technical indispensability and regulatory pressure. Market sizing ranges from approximately USD 6.13 billion in 2025 rising to USD 6.30 billion in 2026 and USD 8.79 billion by 2034 at a 4.2% CAGR, to a narrower high-purity scope valued at USD 403 million in 2024 and forecast to reach USD 636 million by 2031 at a 6.8% CAGR. The qualifying question for buyers is therefore not “what does a tonne of DCM cost” but “which grade, impurity profile and documentation package can my application support under the regulatory regime that applies to my market.”
Core Application Fields and Demand Architecture
DCM demand concentrates in four functional arenas where its non-flammability, high solvency and rapid evaporation are difficult to substitute without reformulating the process: pharmaceutical manufacturing and purification, electronics and precision cleaning, aerosol and foam-blowing applications, and industrial coating removal and adhesives.
In pharmaceutical manufacturing and purification, DCM serves as a reaction solvent, extraction medium, crystallization antisolvent and film-coating solvent. It is used in the synthesis of drug substances and intermediates, in the preparation of sustained-release and enteric coatings, and in the purification of APIs where its volatility allows complete removal to residual-solvent limits. The specification logic here is the most demanding: DCM is an ICH Q3C Class 2 residual solvent, with a permitted daily exposure (PDE) of 6.0 mg/day and a concentration limit of 600 ppm. A pharmaceutical-grade lot must be supported by documentation that demonstrates conformity to the compendial monograph and, where required, a batch-specific residual-solvent profile. The high-purity segment of the DCM market is growing faster than the overall market, at a 6.8% CAGR, precisely because regulated pharmaceutical and electronic applications require lower impurity levels and more complete analytical documentation than technical-grade material can provide.
In electronics and precision cleaning, DCM is used for metal cleaning and finishing, printed circuit board deflashing, and the removal of fluxes, oils and greases from components where non-flammability and fast evaporation are critical. It is also used as a cleaning reagent in precision optics and in the manufacture of film coatings and magnetic media. The specification logic here is low-residue evaporation and material compatibility: a cleaning solvent that leaves a non-volatile residue or attacks a polymer component fails at the device level, not in the certificate of analysis. Electronic-grade DCM therefore commands a premium over technical grade, and the supplier’s ability to document evaporation residue and trace impurities lot by lot is the qualification threshold.
In aerosol and foam-blowing applications, DCM serves as a propellant in aerosol paints, insecticides and automotive products, and as a blowing agent in flexible urethane foam production. The non-flammability of DCM is the defining advantage in aerosol formulations, because it allows a propellant system that does not introduce a flammability hazard into a consumer or industrial product. This segment is structurally exposed to regulatory pressure and to substitution by hydrofluoroolefins and other non-flammable alternatives, but it remains a volume outlet in cost-sensitive and performance-driven formulations.
In industrial coating removal and adhesives, DCM is a powerful paint stripper and a solvent in adhesives, sealants and coating removers. Its high solvency allows it to penetrate and lift cross-linked coatings that resist milder solvents, and it is used in furniture restoration, aircraft and aerospace component maintenance, and industrial equipment refurbishment. This is the segment most directly affected by regulatory restriction: the EU prohibited consumer paint-stripper use in 2010, the U.S. EPA prohibited consumer paint and coating removal in 2019, and the 2024 TSCA rule would have extended restrictions to most industrial and commercial uses before its vacatur. The practical consequence is that the coating-removal segment is progressively narrowing to applications where no technically feasible alternative exists, and buyers in this space must qualify suppliers on their ability to document compliance with the remaining permissible-use framework.
Regulatory Profile: A Non-SVHC Chlorinated Solvent in a Post-Vacatur TSCA Landscape
DCM’s regulatory position is more fragmented than a single hazard classification can capture. The molecule is not a SVHC in the EU, but it carries a harmonised Carc. 2 classification and is subject to a targeted Annex XVII restriction. In the United States, the operative rule was vacated in September 2026, leaving the prior framework in place while EPA reconsiders its approach. This fragmentation means that a supplier’s documentation package must be tailored to the destination market, not applied uniformly.
European Union. DCM is not on the SVHC Candidate List and not subject to Annex XIV authorisation. Regulatory reference material confirms that DCM is “NOT SVHC (kept off in favour of targeted Annex XVII framework)” despite its IARC Group 2A classification and harmonised Carc. 2 status. The operative restriction is REACH Annex XVII entry 59, which prohibits the supply to the general public of paint strippers containing DCM in concentrations ≥0.1% by weight, and imposes restrictions on professional use in certain applications. The CLP classification includes Carc. 2 (H351) , STOT SE 3 (H336) and Skin Irrit. 2 (H315) , and the substance is not classified as a PBT or vPvB. For buyers in the EU, the practical compliance task is to confirm that the grade and packaging are appropriate for the intended downstream use, and that the SDS declares the Annex XVII restriction in the relevant sections.
United States. The regulatory situation is in flux. EPA finalised its TSCA risk management rule in May 2024, which would have prohibited 40 of the 53 conditions of use, including all consumer uses and most commercial and industrial uses, while imposing a Workplace Chemical Protection Program (WCPP) on the uses allowed to continue. EPA subsequently extended the WCPP compliance dates for non-federal laboratories—initial monitoring to 9 November 2026, regulated-area establishment to 8 February 2027, and exposure-control-plan implementation to 10 May 2027—to prevent disruptions to environmental monitoring activities. However, on 15 September 2026, the Fifth Circuit vacated the 2024 rule and the underlying risk determination, holding that EPA’s “whole chemical” approach was unlawful and that the agency must consider PPE where it is actually or foreseeably used. The practical effect is that the 2024 rule is no longer in force as of the court’s decision, but EPA has been remanded to issue condition-of-use-specific determinations, and the prior 2019 consumer paint-removal prohibition remains in place. Buyers cannot assume that the vacatur eliminates compliance obligations: EPA may reissue a revised rule, and downstream customers may impose their own restrictions. A supplier’s ability to provide a clear, current statement of the TSCA status and to support the buyer’s own regulatory assessment is therefore a material qualification criterion.
Russia and the EAEU. DCM is regulated through sanitary-hygienic norms for workplace air. The working-area maximum permissible concentration (ПДК р.з.) is 100/50 mg/m³ (maximum single / shift-average), hazard class 4 (low hazard), and the ambient-air daily average limit is 0.1 mg/m³. Imported material must be accompanied by a Russian-language SDS that states the applicable limits and the required ventilation and PPE measures. DCM is not subject to a REACH-equivalent SVHC listing in the EAEU, but the combination of the EU’s Annex XVII restriction and the U.S. litigation means that Russian buyers are increasingly attentive to the documentation trail, because their own export-oriented customers may require assurance that the solvent is not sourced from a restricted-use channel.
Transport classification. DCM is UN 1593, Class 6.1, Packing Group III, a toxic substance by inhalation. It is non-flammable, which simplifies storage relative to Class 3 solvents, but the inhalation toxicity classification requires careful labelling and transport documentation.
Global Supply Structure and Manufacturer Differentiation
Global DCM supply is moderately concentrated at the high-purity end and more fragmented at the technical-grade end. Production is integrated with chlor-alkali and methane chlorination capacity, and the producer landscape includes large diversified chemical companies with chlorinated-solvent portfolios alongside regional producers serving domestic technical-grade demand. The high-purity segment—defined by low water, low acidity, low evaporation residue and controlled trace metals—is more concentrated than the technical-grade segment, because the analytical and packaging discipline required to hold those specifications is a barrier to entry.
Differentiation operates on three axes that matter more to a pharmaceutical process chemist or an electronics engineer than the headline assay.
The first is residual-solvent documentation. DCM is an ICH Q3C Class 2 solvent with a 6.0 mg/day PDE and a 600 ppm concentration limit. A pharmaceutical-grade lot must be accompanied by a certificate of analysis that supports the buyer’s own residual-solvent risk assessment, and the supplier’s ability to provide lot-specific data on non-volatile residue, acidity and water is what separates a GMP-compatible supplier from a technical-grade vendor.
The second axis is regulatory clarity and documentation depth. The U.S. TSCA landscape is unsettled, and the EU Annex XVII restriction imposes specific downstream-use conditions. A supplier that can provide a clear, current statement of the TSCA status—including the effect of the Fifth Circuit’s vacatur—and an SDS that correctly declares the Annex XVII entry 59 restriction, is a supplier that a buyer’s regulatory affairs team can qualify without commissioning a separate legal review.
The third axis is grade breadth and dangerous-goods logistics. DCM moves in bulk, ISO tanks, drums and IBCs, and the UN 1593 Class 6.1, PG III classification means packaging and transport documentation are part of the product. A supplier that can offer technical-grade, pharmaceutical-grade and high-purity electronic-grade material from a consistent production and analytical platform, and arrange compliant dangerous-goods logistics to Russia and the EAEU with Russian-language SDS and UN 1593 documentation, reduces the buyer’s qualification and clearance burden.
Regional Demand Dynamics
DCM demand follows pharmaceutical manufacturing, electronics production and industrial coating removal rather than the geography of chlorine or methanol feedstock.
Asia-Pacific is the largest and most dynamic region, supported by API and generic-drug manufacturing in India and China, electronics assembly across East and Southeast Asia, and industrial maintenance demand. Pharmaceutical-grade DCM demand is growing with the expansion of generic-drug production, and the high-purity segment is growing faster than the overall market at a 6.8% CAGR. The region’s regulatory environment is varied, but export-oriented pharmaceutical and electronics manufacturers increasingly require documentation aligned with ICH Q3C and with destination-market restrictions.
North America and Europe are mature, specification-intensive markets. North American demand is anchored in pharmaceutical manufacturing, electronics cleaning and industrial coating removal, with the TSCA litigation creating a period of regulatory uncertainty that places a premium on supplier documentation clarity. European demand is shaped by the Annex XVII restriction, which has already removed consumer paint-stripper applications and narrowed professional uses, and by a strong preference for pharmaceutical-grade material with full compendial documentation. Both regions are growing at low-to-mid single digits in volume, with value growth driven by high-purity and regulated applications rather than by commodity technical-grade volume.
Russia and the EAEU form an import-dependent contour with a documented and structurally significant trade flow. Russian market analysis describes the DCM market as stable with an import-substitution trend and a high dependence on imports, with Germany and China identified as the key source countries. Demand has increased in the pharmaceutical and chemical industries, driven by expanded production capacity and growing consumption of specialised solutions, while the market also faces challenges from tighter environmental norms and rising raw-material prices. The working-area OEL of 100/50 mg/m³ and the ambient-air limit of 0.1 mg/m³ set the industrial-hygiene envelope, and buyers in the region place a premium on suppliers that can provide a Russian-language SDS with those limits clearly stated, lot-specific analytical data, and UN 1593 dangerous-goods documentation. XINCHEM positions its DCM supply around this requirement, combining pharmaceutical-grade and technical-grade material with Russian-language SDS support and lot-specific residual-solvent data so that Russian and EAEU buyers can qualify imported material without reconstructing the compliance case internally.
Future Outlook and Strategic Imperatives
The DCM market will grow at a moderate rate in volume—mid-single digits depending on scope—but the composition of that growth is shifting toward high-purity and regulated applications, while the technical-grade coating-removal segment faces progressive narrowing under regulatory restriction.
Three structural forces will shape competition. First, the U.S. TSCA vacatur creates a window of regulatory uncertainty that rewards documentation depth. The Fifth Circuit’s decision has removed the 2024 rule from force, but EPA has been remanded to issue condition-of-use-specific determinations, and the 2019 consumer paint-removal prohibition remains. Suppliers that can explain the current status clearly, and that can support a buyer’s own risk assessment with lot-specific data and SDS declarations, will be preferred over those that offer a generic compliance statement. Second, the EU Annex XVII restriction will continue to define the permissible-use perimeter. DCM is not a SVHC and not subject to authorisation, but entry 59 has already reshaped the paint-stripper market and imposes conditions on professional use. Pharmaceutical and electronics applications remain the core demand base, and high-purity grades will command a growing share of value. Third, grade-specific impurity control and residual-solvent documentation will remain the performance differentiators. A technical-grade lot that carries water or acidity above the pharmaceutical specification can fail a crystallization or a coating step, and a supplier that documents lot-level residue and acidity data reduces the buyer’s re-assay burden.
For Russian and EAEU buyers, the strategic implication is that DCM procurement should be treated as a documentation-and-grade partnership rather than a price comparison. A lot that arrives without a clear statement of the current TSCA status, or without a Russian-language SDS that states the 100/50 mg/m³ OEL, does not simply cost the price of the drum; it can trigger a customer audit finding or a regulatory affairs delay. A shipment that lacks UN 1593 documentation can be held at customs and disrupt a continuous pharmaceutical or electronics process. The lowest-risk supplier is the one that can match the grade to the application, document residual solvents and acidity lot by lot, explain the regulatory status of the destination market clearly, and support the buyer with Russian-language documentation and compliant dangerous-goods logistics—the position XINCHEM occupies for DCM in the Russian and EAEU market.

Our DCM is supplied with controlled water, acidity and evaporation residue, lot-specific certificate-of-analysis data, and the regulatory documentation—including a clear statement of the current U.S. TSCA status, the EU Annex XVII entry 59 declaration, Russian-language SDS with the 100/50 mg/m³ OEL, and UN 1593 Class 6.1 transport documentation—that grade-specific qualification and cross-border compliance require.
Technical and Quality Advantages
Grade-Specific Impurity Control: DCM is supplied against technical-grade, pharmaceutical-grade and high-purity specification windows, with water, acidity, evaporation residue and trace impurities controlled to the limits relevant to the intended use. Because residual water and acidity affect crystallization, coating adhesion and electronic residue performance, lot-level data is the specification that determines whether the lot can enter a GMP process or a precision cleaning line rather than only an industrial stripping application.
ICH Q3C Residual-Solvent Documentation: Pharmaceutical-grade DCM is supported by a certificate of analysis that reports the parameters relevant to the buyer’s ICH Q3C Class 2 assessment—non-volatile residue, acidity, water and assay—so that the buyer can demonstrate conformity to the 6.0 mg/day PDE and 600 ppm concentration limit without re-characterizing every lot.
Regulatory Clarity Across Jurisdictions: XinChem provides a clear, current statement of the U.S. TSCA status, including the effect of the September 2026 Fifth Circuit vacatur and the status of the 2019 consumer paint-removal prohibition, alongside an SDS that correctly declares the EU REACH Annex XVII entry 59 restriction. For Russian and EAEU buyers, the Russian-language SDS states the 100/50 mg/m³ working-area OEL and the 0.1 mg/m³ ambient limit.
Russian-Language SDS and UN 1593 Documentation: Safety data sheets are available in Russian and English, with documentation covering the Carc. 2, STOT SE 3 and Skin Irrit. 2 classification, the applicable exposure limits, and the UN 1593, Class 6.1, PG III transport classification. This package reduces clearance friction for a toxic-by-inhalation solvent that requires dangerous-goods documentation despite being non-flammable.
Packaging and Logistics Flexibility
DCM is available in bulk and ISO tanks for large-volume pharmaceutical and industrial customers, in 200 L drums and IBCs for mid-scale formulation and cleaning operations, and in sealed containers for pilot, laboratory and high-purity qualification. For Russia and EAEU destinations, XinChem arranges Class 6.1 dangerous-goods logistics with UN 1593 documentation, Russian-language SDS and certificate-of-analysis support, reducing clearance friction for a product that is non-flammable but toxic by inhalation.
Application Support and Supply Reliability
XinChem’s technical team assists with grade selection for API synthesis and purification, film coating, electronics cleaning and deflashing, aerosol and foam formulation, and industrial coating removal, and with the residual-solvent and regulatory-status documentation that pharmaceutical and electronics qualification demands.
