In 2024, the U.S. Environmental Protection Agency issued the final rule for risk management of tetrachloroethylene (PCE), setting phased requirements for manufacturing, processing, distribution, retail, and certain industrial and commercial uses. EPA data shows that the first universal ban date for the manufacturing stage is June 11, 2026, for the processing stage is September 9, 2026, and for the distribution node targeting retailers is December 8, 2026. Different uses may have exceptions, transition periods, or workplace control requirements, so one should not consider only a single date.
PCE is also known as perc or tetrachloroethylene, with CAS number 127-18-4. It was once used in dry cleaning, metal degreasing, brake cleaners, adhesives, and several industrial processes. The supply chain verification here does not mean that all household cleaners contain PCE, but it is a reminder to companies that when the target market and product use may fall under relevant regulations, they should first confirm the facts from raw materials and formulation documents.
The first step is to restore the product name to its chemical identity. Suppliers may use trade names, mixture names, or abbreviations, and the project team needs to match them with CAS numbers, safety data sheets, concentration ranges, and uses. If the raw material documents only state 'solvent' or 'additive,' which is insufficient to support regulatory assessment, the supplier should be requested to complete the composition and regulatory information.
The second step is to differentiate the use. The regulatory pathways for the same substance may vary in consumer goods, professional cleaning, industrial processing, dry cleaning, or other approved uses. The product descriptions provided by the sales team, the functions recorded by the formulation team, the actual usage scenarios by customers, and customs declaration information need to be consistent and cannot be inferred based solely on an internal product name.
EPHYON's daily chemical cleaning OEM/ODM services include requirement communication, formulation and samples, packaging support, production, and delivery. For projects in target markets with specific chemical regulations, information such as the country or region, customer channel, intended use, formulation version, and supplier documents can be recorded at the project initiation stage, allowing R&D, procurement, quality, and delivery teams to collaborate around the same version.
The third step is to connect inventory with the timeline. Recipe changes do not mean that old materials and old finished products automatically disappear. Companies also need to know the batches of raw materials, work-in-progress, finished product inventory, customer warehouse stock levels, and the dates to stop purchasing or shipping, in order to avoid mixing old and new recipes, different labels, and different market versions under the same material code.
In 2026, the EPA adjusted the dates for certain workplace chemical protection programs again and continued to review the rules. The EPA also stated that the current deadlines remain in effect until the formal amendments take effect. Therefore, companies should not interpret 'under reconsideration' as a suspension of all requirements, nor should they treat the dates in the proposal as final deadlines that have already taken effect.
Workplace controls and the circulation of goods are two lines that need to be managed separately. OSHA information on the dry-cleaning industry emphasizes ventilation, equipment maintenance, leak control, personal protection, and training; TSCA regulations also involve manufacturing, processing, distribution, and specific uses. Procurement documents, safe operations, customer declarations, and market access information should each have responsible persons identified.
For cleaning products and related OEM projects, the most valuable action is a continuously updated version list: raw material names and CAS numbers, formula numbers, product uses, target markets, sales channels, supplier document dates, inventory status, and applicable regulatory nodes. It cannot replace legal judgment, but it allows decisions to be based on actual formulas and flows, and also enables quick identification of affected versions when regulations change.
