Key takeaway
What This Development Means
Mexico has notified draft PROY-NOM-019-SICT2/2026 on cleaning vehicles used to transport hazardous substances, materials and wastes. The proposal would cover shippers, carriers, consignees, cleaning centres and inspection units, with comments due 24 November 2026.
Is PROY-NOM-019-SICT2/2026 already mandatory?
No. Mexico has notified a draft standard for consultation. Existing legal requirements continue, and the final standard, publication and commencement provisions must be confirmed before the proposed duties are treated as binding.
Which organisations would the proposed standard cover?
The notified scope includes shippers, road carriers, consignees, vehicle-cleaning centres and relevant inspection units involved with hazardous substances, materials and wastes transported by road throughout Mexico, including subcontracted transport and cleaning operations.

Mexico Hazardous Transport Vehicle Cleaning Proposal Opens For Comment
Mexico has notified draft Official Mexican Standard PROY-NOM-019-SICT2/2026 on the cleaning of vehicles used to transport hazardous substances, materials and wastes. World Trade Organization notification G/TBT/N/MEX/584 was circulated on 25 September 2026, with comments due by 24 November.
The proposal would establish technical specifications and general provisions for vehicle cleaning, handling and controlling hazardous remnants and wastes, and documenting those activities. It would apply mandatorily to shippers, road carriers, consignees, persons responsible for vehicle-cleaning centres and relevant inspection units.
The draft is not yet an operative Norma Oficial Mexicana. Current Mexican transport, hazardous-waste, worker-safety and environmental requirements continue to apply. The WTO notification does not itself create an application date, and businesses should wait for the final Mexican publication before stating that new duties are legally in force.
Cleaning Records Would Connect Transport And Waste Compliance
The practical scope reaches beyond a wash procedure. Cleaning hazardous-transport vehicles can generate residues, contaminated wash water, sludge, absorbents and personal protective equipment that may themselves require classification and management as hazardous waste. Operators may need to connect vehicle history, compatibility checks, cleaning method, residue destination and release-to-service evidence.
Shippers should confirm the information supplied about the previous load. Carriers should identify vehicles and tanks that require cleaning before maintenance, change of product or reuse. Consignees should clarify who assumes responsibility after unloading. Cleaning centres should assess containment, ventilation, emergency arrangements, worker protection, waste storage and authorised disposal routes. Inspection units would need procedures aligned with the final conformity-assessment provisions.
Existing Mexican transport and environmental law continues to allocate duties. The proposal would add a more specific cleaning and residue-control framework. It would leave requirements on vehicle integrity, dangerous-goods documentation and hazardous-waste movements in place.
Manufacturers and importers using Mexican road transport should review logistics contracts and confirm whether cleaning is performed by the carrier, consignee or a specialist centre. Records should allow a company to reconstruct the previous cargo, cleaning decision, method, wastes generated and acceptance of the vehicle for its next use.
Foresight analysis: the proposal could reduce contamination and incompatible-load risk by treating cleaning as a controlled handover between supply-chain actors. Its effectiveness will depend on whether final responsibilities and documentary interfaces are sufficiently precise, making the consultation particularly relevant for shared or subcontracted fleets.
Practical call to action: Compare existing cleaning certificates and waste records with the draft, and submit evidence-based comments by 24 November where responsibilities are unclear.
