What is the role of batch numbers in CBM T6 traceability?

• A. Identify individual units for recall.
• B. Tie products to material lots for traceability and recalls.
• C. Track shipping routes.
• D. Compute production costs.

Answer: (B)

Batch numbers in CBM T6 traceability connect finished products to the exact material lots used to make them. This creates a clear link from what’s on the shelf back to the raw materials, components, and production conditions (such as the date and line) that produced it. With that link, if a quality issue is found, you can identify all units that come from the affected batch and recall just those items, rather than broad, blanket recalls. This targeted approach improves recall effectiveness, supports regulatory reporting, and strengthens supplier and process understanding.

Batch numbers aren’t intended to identify individual units or track delivery routes or to compute costs. Individual unit identification would rely on unique serials, not batch-level labeling; shipping routes are a logistics matter, and cost calculations rely on accounting data rather than batch linkage alone.
