PestSheet
Not legal advice. A summary of our reading of the official NOM-256-SSA1-2012 text (checked October 1, 2026). Confirm with the DOF text and the health authority.
What NOM-256-SSA1-2012 requires
The standard is in effect: the Mexican Standards Catalog confirmed it in its last systematic review (January 2, 2023).
The service certificate (section 5.9)
It is given to the service user and must contain:
- Folio (certificate number)
- The establishment's name or business name, address and health license number
- The service user's name or business name and address
- Name and signature of the technical manager, pest controller or owner who performed the service
- The company's phone number
- Type of service: home, commercial, industrial, service or offices
- Control method used
- Pesticide or disinfectant applied, with doses and amounts
- Places and sites treated
- Pests to be controlled
- Safety precautions and recommendations before, during and after the application
- Sketch with the location of traps, baits or other devices, when installed
The standard sets no folio format and doesn't require the client's signature.
Other points of the standard
- Service log (6.4): the establishment must keep a log with a copy of the certificates of the services performed. The standard sets no retention period for it.
- Products (5.7): pesticides must have a sanitary registration, be labeled according to the regulations and not be past their expiration date.
- Re-entry time (7.16.2): where food is sold or prepared, the applicator tells the user the re-entry time and the cleaning needed.
- Recommendations (7.16.4): written safety recommendations are part of the certificate.
- Health license (5.2) and technical manager (6.3): the service must have a health license and a technical manager.
How PestSheet covers it
- Business country "Mexico" in the setup guide or in More > Business profile: the app uses NOM-256 even if the client's state shares a code with a U.S. state
- Certificate in Spanish with the 5.9 data, checked before you complete the visit
- Folios without gaps or repeats: each phone numbers in its own series and a draft never takes a number
- Sketch required only when you install traps or baits
- COFEPRIS sanitary registration per product, with a link to the official lookup
- Optional lot and expiration date; if the product had expired on the service date, the app won't complete the visit
- A field for the re-entry time, printed in the recommendations
- Service log as PDF with a copy of each certificate and as CSV (Pro)
- Quotes and invoices as a "Nota de venta" with no tax validity: you issue the CFDI with the SAT or your PAC
