Mexico Proposes Mandatory Hazardous-Transport Vehicle Cleaning Standard

Mexico has notified draft standard PROY-NOM-019-SICT2/2026 on cleaning vehicles used to transport hazardous substances, materials and wastes. It would replace NOM-019-SCT2/2015, published on 27 January 2016, rather than create the first framework for this activity.

The WTO notification gives 24 November 2026 as its comment deadline. Separately, the Mexican consultation notice provides 60 calendar days from publication on 23 September for domestic submissions.

Scope And Cleaning Evidence

The draft concerns transport on federal-jurisdiction routes and excludes Class 7 radioactive materials. It covers relevant shippers, road carriers, consignees, vehicle-cleaning centres and inspection units.

Section 5.2 requires cleaning in specified circumstances, including incompatibility, repairs, alterations, accidents, integrity testing and permanent withdrawal. It does not require cleaning after every load without qualification.

Sections 5.4.2–5.4.3 address the carriage and content of cleaning evidence, while section 5.5 sets cleaning-centre duties.

Proposed Commencement

The WTO notification leaves adoption and entry-into-force dates undetermined. Draft section 11 proposes commencement 180 calendar days after final publication. The notification and consultation draft do not themselves bring the revised requirements into force.
