Incoming inspection verifies supplier material before it enters the production line, against the criteria the customer defines. RIDYS Group performs it at the plant or in a warehouse, in San Luis Potosí and the Bajío region, with per-lot reporting.
A supplier with a history of failures keeps shipping and you cannot let that material reach the line without verification. Your customer demands evidence of control over incoming material. Or you need to protect the launch of a new component before it reaches the warehouse.
Incoming inspection, or IGI (Incoming Goods Inspection), is the quality control applied to supplier shipments when they arrive at the plant, to detect defects before the material enters the warehouse and production lines.
Visual inspection, functional tests, dimensional inspection, gauge checks, counting of received units, and packaging review, among other verifications depending on the component.
The goal is to validate lot conformity against the quality, logistics, and engineering characteristics defined in the Control Plan.
This service is not performed as 100% inspection. Validation is based on a sample defined in the component’s Control Plan or, if none exists, according to the U.S. military standard MIL-STD.
The statistical methods and operational rules are based on the international standards ISO 2859 for attribute inspection and ISO 3951 for variable inspection.
Incoming inspection manages two opposing risks, and that balance is what makes the service require judgment, not just personnel.
If the rejection level is too high, the line is protected in terms of quality, but in a just-in-time system the process becomes unstable due to material shortages.
If a defective lot is accepted and released to production, the effect is the opposite: assembly, manufacturing, and downstream quality problems, with the resulting instability.
Deciding where that balance sits is a decision made with the customer before starting, not during inspection.
The service can operate in reduced or tightened mode depending on the supplier’s defect history.
As for the sampling scheme, it can be single — the entire sample is taken before deciding to accept or reject — or sequential, where sampling stops as soon as there is statistical certainty that the lot is good enough or bad enough.
The report is defined according to the level of service contracted, in three levels:
Basic. Part number, lot number, inspection date, number of parts inspected in the sample, and accept or reject decision.
Intermediate. The above plus the record of the measurements of each sample in accordance with the data requested in the Control Plan.
Advanced. All of the above, plus variables control charts for dimensional measurements.
All of these settings are directly tied to the level of risk you decide to take: changing the sampling, the acceptance rules, or the statistical confidence changes the result and the cost of the service.
Personnel trained on the component’s specific criteria, with supervision on the floor. Every service runs with a responsible lead and a supervision and coordination structure that verifies the inspector’s work.
ISO 9001:2015 certification (Orion Registrar, ANAB accredited) and REPSE (Mexico’s Registry of Specialized Service Providers) registration ARR197/2024 with Mexico’s Ministry of Labor (STPS). Personnel with DC-3 certificates and documented training records. Our processes are carried out in accordance with our customers’ IATF 16949 requirements.
San Luis Potosí is our operating base. We serve plants in San Luis Potosí, Guanajuato (León, Silao, Irapuato, and Celaya), Querétaro, and Aguascalientes; on request, also in Jalisco and in Saltillo and Ramos Arizpe, Coahuila.
The service can be executed on the customer's premises, in a warehouse, in a distribution center, or on the supplier's premises.

No. It is performed by sampling, according to the component’s Control Plan or the MIL-STD standard. If the case requires 100%, the appropriate service is sorting or containment.
It is defined with the customer based on the Control Plan and the acceptable risk level, following ISO 2859 or ISO 3951 depending on whether inspection is by attributes or by variables.
It is segregated, identified, and documented. The final disposition—return to supplier, sorting, or rework—is defined by the customer.
Part number, receiving volume, characteristics to verify, location, shifts, and estimated duration.
Describe the material, the defect, and the volume, and we will send back a proposal with rate, start-up time, and reporting scheme.
