EHS for Shelter Companies in Mexico
You are legally responsible for the EHS compliance of every client, but each operation has different hazards, materials and NOMs. One platform to manage it all without losing control.
One legal entity. Many operations. Full responsibility.
As employer and IMMEX holder, the Shelter assumes responsibility before STPS, SEMARNAT and PROFEPA. Even if the client runs production, the Shelter owns the legal risk: NOM fines, civil protection failures or environmental violations are attributed to its entity.
STPS
41 NOMs, multiplied by client operations.
Each client operation under a Shelter activates its own subset of the 41 STPS NOMs. The operator must manage safety programs, PPE matrices and risk analyses per plant. NOM-030 requires annual diagnostics, NOM-019 requires commissions per facility and NOM-035 applies to the entire IMMEX workforce without exception.
SEMARNAT
Environmental compliance per operation.
Each operation generates waste and emissions with specific obligations. Automotive painting requires a LAU (VOC emissions), while medical devices or chemical mixing require hazardous waste generator registration and manifests with SEMARNAT. The Shelter tracks everything under one entity, but with operational rigor per plant.
Civil Protection + Municipal
Multi-site risk management.
Each plant in the Shelter portfolio requires its own Civil Protection program, municipal license and emergency plan. With 15 operations in different cities, the burden scales to more than 800 compliance items. The Shelter legally assumes this complexity driven by each client's specific risk profile.
Client Audits
Global standards compliance.
Foreign clients demand more than the Mexican legal framework. Your operation requires evidence for ISO 45001, ISO 14001 and OSHA standards. Sectors like aerospace and medical add AS9100, NADCAP or GMP requirements. The Shelter must prepare corporate and government audits under the same system.
WHY SHELTER IS DIFFERENT
You don't own the process. You own the risk.
EHS in shelter has a unique challenge: the company responsible for compliance does not control the process that generates the requirements. The client decides what to produce, what materials to use and what processes to run. The Shelter must translate those decisions into regulatory obligations and manage them.
Onboarding and compliance configuration
When starting an IMMEX operation, we assess processes and hazards to create the compliance catalog. We define STPS NOMs, SEMARNAT permits and PPE matrices before production begins.
Portfolio diversity
Managing harnesses (NOM-004), chemicals (NOM-005) or medical devices (COFEPRIS) requires unique risk profiles. Each plant demands differentiated evidence and industrial safety plans.
Client transitions and graduations
When a client becomes independent, their compliance records and environmental permits must be separated with precision. Our platform enables agile onboarding and clean history closures.
Multi-campus operations
Centralize visibility in Juárez, Tijuana or Querétaro. Manage municipal regulations and different STPS or SEMARNAT delegations from a control dashboard for your parks.
Dual accountability
Comply with Mexican authorities and deliver incident dashboards to foreign clients. Serve two audiences: government legal rigor and corporate transparency.
One shelter, multiple EHS configurations
Automotive Client Operations
Automotive is the sector most served by shelter companies in Mexico: harnesses, stamping, injection molding and sub-assembly. Heavy machinery, welding and chemical finishes define the production floor. EHS complexity scales with the process—from PPE and material handling to machinery safety, LOTO, hazardous chemicals and SEMARNAT permits. OEMs like GM, Ford and BMW require ISO 45001 and periodic EHS audits.
Key Risk
HOW NAPSSOFT SOLVES IT
EHS compliance audits by automotive OEMs are critical for supplier qualification and permanence in the supply chain.
A failure in regulatory management within the shelter model can result in total loss of global clients due to lack of operational guarantees.
The absence of digital records on machinery safety and LOTO weakens OEM trust and compromises the continuity of existing contracts.
HOW NAPSSOFT SOLVES IT
Configure specific EHS catalogs by automotive operation type to provide visibility and structure to the entire shelter portfolio.
Track in real time machinery certifications, LOTO lockouts, noise monitoring and PPE use segmented by each production line.
Generate technical evidence packages ready to respond to both federal STPS inspections and OEM client audits.
Key Permits/NOMs:
ISO 45001 / ISO 14001
Machinery safety (NOM-004)
Hazardous chemicals (NOM-005 / NOM-018)
LAU environmental license
OEM audits
Aerospace Client Operations
Aerospace manufacturing under shelter in Mexico is concentrated in Querétaro, Baja California, Sonora and Chihuahua: composites, machining, wiring, avionics and surface treatment. Aerospace clients demand the highest audit standards: AS9100, NADCAP accreditation and specific programs from Boeing, Airbus, Safran and GE—all with EHS components. Chemical processes like anodizing and electroplating activate the full set of SEMARNAT permits and NOM-028.
Key Risk
HOW NAPSSOFT SOLVES IT
Loss of NADCAP accreditation due to documentation failures stops production and cancels the validity of special processes.
Aerospace clients strictly audit EHS compliance as a mandatory requirement to qualify and maintain their suppliers.
HOW NAPSSOFT SOLVES IT
Manage aerospace sector-specific requirements integrated with standard STPS and SEMARNAT regulations in a single platform.
Link NADCAP and AS9100 audit calendars with EHS technical evidence, tracking chemical inventories and SDS by operation.
Key Permits/NOMs:
AS9100 / NADCAP
Hazardous chemicals (NOM-005 / NOM-018)
Air quality (NOM-010)
Updated PPE (NOM-017 2024)
Confined spaces (NOM-033)
Medical Device Client Operations
Medical devices is one of the fastest-growing shelter segments in Mexico, concentrated in Baja California, Chihuahua and the Bajío: from disposables to implantable devices with clean rooms. Operations add COFEPRIS on top of STPS and SEMARNAT. Manufacturing for sale in Mexico requires GMP under NOM-241-SSA1-2025: clean room validation, quality systems and COFEPRIS inspections. Export operations require ISO 13485 and FDA-equivalent systems with EHS components.
Key Risk
HOW NAPSSOFT SOLVES IT
Revocation of GMP certification by COFEPRIS stops production and blocks commercialization in the Mexican market.
FDA audits demand rigorous safety and facility standards that, if not met, close access to the international market.
HOW NAPSSOFT SOLVES IT
Manage COFEPRIS GMP compliance alongside STPS and SEMARNAT regulations through a centralized and preventive digital system.
Track clean room validations, sterilization processes and manifests to generate evidence ready for COFEPRIS, FDA and clients.
Key Permits/NOMs:
ISO 13485 / MDSAP
STPS occupational safety
COFEPRIS GMP (NOM-241-SSA1-2025)
ISO 45001 / ISO 14001
Hazardous chemicals (NOM-005 / NOM-018)
Electronics and Consumer Products Client Operations
Electronics manufacturing under shelter in Mexico covers PCB assembly, cables, connectors, packaging and EMS services, concentrated in Tijuana, Ciudad Juárez and Reynosa. EHS requirements vary by process. Simple assembly has minimal exposure. Soldering introduces lead and flux. SMT lines use cleaning solvents. Battery assembly adds fire and chemical spill risk. The Shelter must configure EHS by process, not by building.
Key Risk
HOW NAPSSOFT SOLVES IT
Lead exposure from soldering is the most critical STPS finding in electronics and can result in sanctions for health risks.
RBA audits for major global brands require detailed EHS qualification that conditions permanence in the supply chain.
HOW NAPSSOFT SOLVES IT
Configure compliance by process, assigning lead monitoring to soldering and ergonomics programs to assembly lines.
Centralize NOM-005 and NOM-010 programs for chemical processes under a digital portfolio view designed for the shelter model.
Key Permits/NOMs:
ISO 45001 / ISO 14001
RBA (Responsible Business Alliance)
Hazardous chemicals (NOM-005 / NOM-010)
Soldering waste SEMARNAT
Civil protection
Chemical, Plastics and Specialized Manufacturing Client Operations
Some shelter operations involve high-risk manufacturing: chemical mixing, compounding, specialized coatings and industrial adhesives. They activate NOM-028, the full SEMARNAT high-risk program and the most rigorous STPS inspection profile. For the Shelter, these operations represent the highest compliance cost and the greatest legal exposure. A spill, explosion or environmental release under the IMMEX permit affects the entire entity—not just the client involved.
Key Risk
HOW NAPSSOFT SOLVES IT
Serious incidents such as explosions or toxic leaks under NOM-028 can cause permanent facility closure by PROFEPA.
A single safety failure in a high-risk operation jeopardizes the Shelter's entire IMMEX program and the continuity of all its clients.
Non-compliance with industrial safety protocols in chemical processes results in workplace fatalities and unavoidable criminal liabilities.
HOW NAPSSOFT SOLVES IT
Configure the high-risk catalog including NOM-028 process safety, hazardous substance inventories and digital SDS management.
Integrate SEMARNAT accident prevention programs with exposure monitoring and real-time emergency response plans.
Isolate compliance for critical operations to protect the Shelter portfolio while maintaining full visibility through operational dashboards.
