Pack 151 final: the kit for plant operators on the Saltillo–Apodaca IMMEX corridor
Pack 151 final equips the new hire at an IMMEX manufacturing plant along the Saltillo–Ramos Arizpe–Santa Catarina–Garcia–Apodaca corridor. Hard hat stamped with the operator's seal (Stellantis, GM, KIA, Bosch, Magna, Linamar), ANSI Z87.1 safety eyewear, high-visibility polo with embroidered operator logo and plant code, 16 GB USB preloaded with the industrial safety manual and the egress matrix. SAT invoicing is issued with CFDI 4.0 and the foreign trade complement when the unit crosses the border, plus 16% IVA for domestic consumption. Delivery is scheduled in advance of the annual IMMEX audit by the Secretariat of Economy (SE).
The northern IMMEX cluster and plant logistics
The Saltillo–Ramos Arizpe corridor concentrates more than 180 plants operating under the IMMEX programme (Manufacturera, Maquiladora y de Servicios de Exportacion) and forms the automotive backbone of northern Mexico. Cluster plants produce harnesses, transmissions, engine blocks, cylinder heads, stamped parts and electronic components for OEM customers in the United States, Canada, Germany and Japan. The IMMEX regime allows temporary import of inputs for transformation and subsequent export, supported by a temporary import pedimento issued by a licensed customs broker.
A plant operator carries a high-visibility corporate uniform, ANSI Z87.1-rated safety eyewear, a hard hat stamped with the plant code, dielectric footwear and a badge with a QR traceability code. The kit is refreshed every quarter as the uniform wears out, with HR handling distribution by badge number. Pack 151 final delivery is scheduled ahead of the annual SE (Secretaria de Economia) audit, which runs between February and April.
The IMMEX plant invoices from its fiscal domicile in Ramos Arizpe, Saltillo or Garcia under the general regime of Mexican income tax law. CFDI 4.0 carries a per-badge, per-plant, per-period breakdown. Items shipped to operators at sister plants in Texas or Tennessee use the foreign trade complement, a definitive export pedimento and 0% IVA under the IMMEX programme. Carta Porte 3.0 documents the transit from the matrix plant to the OEM customer abroad.
IMMEX corporates with operations across Coahuila and Nuevo Leon schedule deliveries in four waves: January (Q1 launch preparation), July (preparation for the August technical stop), September (preparation for the IMMEX audit) and November (preparation for the year-end stop). Delivery uses specialised couriers (FedEx, DHL, UPS) with 5 to 8 day transit to sister plants in the United States, or dedicated consolidated freight (Castillo, TUM, Tres Guerras) for lots above 100 kits.
What is included in Pack 151 final
The kit ships in a rigid case stamped with the operator's seal and the plant code, identified by badge number and shift. Each piece is embroidered, laser-engraved or printed with the operator's logo for inventory control and brand traceability.

How the kit is invoiced
Pack 151 final invoices with CFDI use I08 when charged as industrial operations expense, or G03 when charged as general expense. The IMMEX plant invoices from its fiscal domicile in Ramos Arizpe, Saltillo, Garcia or Apodaca under the general fiscal regime. Items shipped to operators at sister plants in the United States use the foreign trade complement, definitive export pedimento and 0% IVA under the IMMEX programme.
An IMMEX corporate with five or more plants in the northern corridor issues a single consolidated invoice with per-plant, per-badge and per-period breakdown. Deductibility operates under Article 27 of the Mexican Income Tax Law (LISR) as industrial operations expense, supported by a badge list signed by plant management and a current tax situation certificate (Constancia de Situacion Fiscal). CFDI 4.0 with foreign trade complement cancels automatically at the close of the fiscal period.
For IMMEX corporates reporting sustainability and compliance indicators, Pack 151 final provides supporting evidence: the certified hard hat reduces plant incidents, the ANSI Z87.1 eyewear meets STPS regulation, the USB with LOTO procedure documents mandatory training. CFDI 4.0 with breakdown of certified pieces supports the operator's sustainability report and ESG disclosures.
IMMEX seasonality and plant technical stops
The northern IMMEX cluster runs two major technical stops each year: the year-end stop (week 52 to week 1) and the mid-year stop (week 28 to week 30). During the stop the plant receives major maintenance, equipment calibration and line restart with new personnel. Pack 151 final is delivered ahead of the restart so the new operator has a full kit on day one.
IMMEX corporates report 8% to 15% quarterly turnover in plant operators, with continuous flow of new hires and exits that drives constant kit replenishment. The annual contract with safety stock and 5 business day replenishment covers the continuous flow of high and lows. Delivery is scheduled around the hiring peaks: January (Q1), July (Q3), September (IMMEX audit).
Production lead time is 12 to 18 business days for runs of 50 kits or more, 18 to 22 days for runs above 200 kits. Plant delivery uses specialised couriers with 1 to 2 day transit for plants on the Saltillo–Ramos Arizpe corridor. For sister plants in the United States (Texas, Tennessee, Ohio), transit is 5 to 8 days with international courier and export pedimento.
