The Importance of Traceability: From Raw Material to the End Customer

A supplier calls on Tuesday afternoon to report that one of their raw material batches had contamination at the source plant. The company needs to know, as quickly as possible, which of its finished products incorporated that batch, on which dates they were produced and which customers received them. The quality team starts reviewing records: some are in spreadsheets from last month, others are handwritten notes from the operator who did the receiving, and others simply do not exist because the internal transformation was never documented. Four hours later, the company cannot answer with certainty which customers received affected product, and must make the most costly and conservative decision: withdraw all batches from the period from the market so as not to assume the risk of a claim.

The Importance of Traceability: From Raw Material to the End Customer

Traceability is the ability to track the origin, path and destination of a product throughout the supply chain, from raw material receiving to final customer delivery. A robust traceability system reduces the scope and cost of any quality or compliance problem.

Why Traceability Is an Operational Necessity Before Being a Regulatory Requirement

Traceability is usually introduced into business management as a regulatory compliance requirement, but its real value operates in a much broader dimension. A complete traceability chain allows damage to be contained in any quality or safety problem with surgical precision rather than a blunt instrument: instead of withdrawing all production from a period, the company can identify exactly which batches are affected and act on those only. In sectors where the value of in-transit inventory can represent several million pesos, that difference in the scope of the corrective action can be the difference between a manageable incident and a first-magnitude operational crisis.

Backward Traceability: The Origin of Each Batch and Each Input

Backward traceability allows precise answers to the question that a quality inspector or affected customer will ask at the worst moment: where does this product come from? That means recording, at the moment of receiving, the supplier's batch number, the date of warehouse entry, the assigned storage conditions and the status of the incoming quality review. If that information is not captured digitally and linked to the product from the first movement, the entire subsequent traceability process starts with a gap that no technology can retroactively fill.

In our WMS module, merchandise receiving includes the mandatory capture of batch, expiration date and supplier at the moment of scanning, establishing the first link in the chain with documentary precision.

Internal Traceability: The Weakest Link in Operations Without Systems

Internal traceability -- which documents what happens to the product inside the company -- is the most vulnerable segment of the chain in operations without integrated systems. Every product transformation, every transfer between warehouses, every inventory adjustment and every production process that combines different batches must be recorded in a way that allows the complete genealogy of the finished batch to be reconstructed. When those records are manual or partial, internal traceability is an illusion: the company believes it can trace, but when it really needs to, it discovers the chain is broken at one of the intermediate links.

In the Oasys platform, transformation and production orders automatically record input batches and the finished product batch they generate, building the genealogy in real time without depending on the operator to manually document the process.

Forward Traceability: Knowing Exactly Who Received Each Batch

Forward traceability is what allows the critical question to be answered in a recall or claim scenario: who received the affected product and when? In our platform, the TMS module records shipment traceability down to the customer's receiving signature, linked to the batch of the shipped product. That means that in any quality problem, the company can generate in minutes the complete list of affected customers with delivery date and invoice number, without having to review files or reconstruct scattered information.

What Regulations in Mexico Require Documented Traceability

In the food and beverage sector in Mexico, NOM-251-SSA1-2009 establishes hygiene practice requirements that include documentation of batch procedures and ingredient tracing capacity. In the pharmaceutical sector, NOM-059-SSA1-2015 establishes batch traceability requirements for medications. For companies that export or work with large retail chains, GS1 product identification standards include batch traceability as an operating condition. Complying with these requirements without an integrated digital traceability system is practically impossible at scale, because the volume of information that must be captured, maintained and retrieved far exceeds the capacity of any manual process.

Frequently Asked Questions

How long does it take to complete an affected batch trace exercise with the Oasys system?

With complete traceability operating on our platform, tracing an affected batch -- from identification of the raw material batch to the list of customers who received the finished product -- can be completed in less than 15 minutes. That same exercise, performed manually in operations without a system, can take between 4 and 48 hours depending on the existing level of documentation, and with a margin of error that no manual process can eliminate.

Is it possible to implement batch traceability in a company that currently has no digital records of its inventory movements?

Yes, and it is one of the most common scenarios in our implementations. The starting point is parameterization of the product catalog with its batch and expiration characteristics, followed by an initial physical inventory phase that establishes the system's starting position. From that point on, every new movement is recorded with complete traceability. The history prior to implementation cannot be traced retroactively, but the system begins building the evidence chain from the first day of operation.
