How do we trace the exact batch of flour used in a biscuit box?

We trace the exact batch of flour used in a biscuit box by linking the finished product lot code to our digital inventory system. This software records the receiving date, inspection results, and production line data for every raw material batch. Our Quality Assurance (QA) team uses this data chain to trace any ingredient from the warehouse to the consumer quickly and accurately.

Decoding lot codes on the packaging

Every box of Atela, Braka, or Pingo biscuits leaves our Thach That - Quoc Oai factory with a unique lot code. This alphanumeric code is printed directly on the primary packaging. It contains the production date, the specific shift number, and the manufacturing line identifier. For example, the code indicates if the biscuit was baked on line one during the morning shift.

Our warehouse staff scans these codes before loading pallets onto delivery trucks. This scan assigns the finished goods to a specific outbound shipment. It creates the final link in the traceability chain before the product reaches distributors in our 63 provincial markets. The lot code acts as the primary key to unlock the entire product history. We apply this same coding standard to our candies, snacks, nutritional cereals, and chocolate products. OEM clients also rely on these codes to track their custom orders.

Querying the inventory software system

When a distributor raises a question about a specific box, our QA personnel start the trace. They enter the lot code from the packaging into our internal management software. The system maps the finished product batch directly to the exact manufacturing order. This order acts as a digital blueprint for that specific production run.

The software generates a complete bill of materials consumed during that shift. It lists the internal lot numbers assigned to the flour, sugar, and packaging materials. A typical database query takes only a few minutes to display this information. We eliminate the risk of human error by avoiding manual paper logs for this step. The production supervisors input consumption data in real time via tablets on the factory floor. This ensures the digital records match the physical material usage accurately.

Reviewing warehouse receiving records

Once the QA team identifies the internal lot number for the flour, they investigate the receiving logs. They trace the internal number back to the exact date the truck arrived at our facility. The system displays the supplier details and the original batch number provided by the flour mill.

Our purchasing department reviews this data to evaluate supplier consistency and lead time (the duration between order placement and material delivery). Warehouse operators use the system to verify the physical storage history. They confirm the flour was stored in the correct dry zone before entering the production area. The software also enforces a strict first-in, first-out inventory method. If an operator attempts to scan a newer batch of flour before an older one, the system flags an error. This prevents material expiration and ensures consistent ingredient freshness.

Verifying quality control test results

The traceability process extends into the laboratory. Before the warehouse team accepts any raw material delivery, our Quality Control (QC) inspectors must approve it. They draw physical samples from the delivery truck based on standard sampling plans. The inspectors test the flour for several key parameters:

• Moisture content: To ensure the flour is dry enough for proper storage.
• Protein levels: To guarantee the correct texture for our crackers and biscuits.
• Physical impurities: To verify the raw material is free from foreign objects.

The software stores these lab results alongside the receiving record. When tracing a finished biscuit, the QA team can pull the exact lab report generated weeks earlier. They verify that the flour met all technical specifications before it was authorized for use. This documented proof of testing is a strict requirement for our operations. It is necessary for maintaining our ISO 22000:2018 food safety management system certification. It also satisfies the strict documentation rules for our Halal (HCA/JAKIM) certification and FDA facility registration.

Managing non-conformities and recalls

Traceability is a critical tool for operational risk management. Sometimes a supplier notifies us of an issue with a past raw material delivery. We must reverse the tracing process immediately. The QA team searches the software for the affected flour batch number provided by the supplier.

The system generates a comprehensive list of all finished goods produced using that specific flour. Our logistics and export-import teams then identify exactly which clients received those boxes. They can pinpoint whether the product went to a domestic distributor or was shipped to one of our nearly 20 export markets. This precise targeting prevents widespread disruption. It protects our proprietary brands, including Nutrinut, Coconut, Oceanfish, KOME, and LIBRA. It also provides complete peace of mind for our international OEM partners.

Rigorous traceability requires seamless coordination between QA, production, warehouse, and purchasing teams. We constantly upgrade our digital systems to improve tracing speed and accuracy.
