As of July 1, 2026, Connecticut formally prohibits the manufacture, sale, and distribution of certain consumer products containing intentionally added per- and polyfluoroalkyl substances, known as PFAS.
The ban applies unless manufacturers first provide prior notification to the Connecticut Department of Energy and Environmental Protection, commonly referred to as DEEP.
Affected products must also carry a compliant PFAS label, adding a visible consumer-facing requirement to the existing notification obligations.
The notification and labeling requirements cover a defined list of product categories, including apparel, carpets, rugs, cookware, cosmetic products, and dental floss.
Additional categories subject to the rules include cleaning products, fabric treatments, children’s products, menstruation products, textile furnishings, ski wax, and upholstered furniture.
Connecticut’s approach shares similarities with a labeling rule recently finalised by New Mexico, which requires a label for products manufactured after January 1, 2027.
New Mexico’s final rule, published on May 5, 2026, requires that the label display an outline of an Erlenmeyer flask with the word “PFAS” written inside the flask.
Connecticut’s acceptable label goes a step further, requiring an outline of an Erlenmeyer flask with both the word PFAS and an exclamation point inside the flask.
The inclusion of the exclamation point is notable because New Mexico itself had proposed that addition in October 2025, only to remove it from the final published rule.
DEEP retains the authority to approve alternative words or symbols for use on product labels upon petition, and will post any additional approved words or symbols to its official web page.
The divergence between the two states highlights a growing patchwork of PFAS labelling standards across the United States, creating potential compliance complexity for manufacturers selling products in multiple states.
Businesses operating across state lines will need to carefully review each jurisdiction’s specific label format requirements to ensure their products meet all applicable rules before reaching consumers.
