Which traceability approach does CBM T6 use for recalls and batch records?

• A. Lot/batch traceability ties a product to material lots.
• B. Serial number traceability traces individual units.
• C. CBM T6 uses batch numbers for recalls and batch records.
• D. CBM T6 uses both batch and serial traceability for recalls.

Answer: (C)

CBM T6 uses batch numbers for recalls and batch records. That means every product from a single manufacturing run shares one batch identifier, tying it to the same set of materials, equipment, and processing steps. When a issue is found, recalling or inspecting is efficiently handled by pulling the entire batch identified by that number, rather than searching for specific units. Batch records then provide the complete history for that batch—raw material lots, process parameters, in-process checks, and final test results—so you can verify what happened in that production run and trace any potential root causes. Serial-number traceability would focus on individual units, which isn’t the approach used here for recalls and batch records, and adding both would complicate the system unless there’s a specific need for unit-by-unit tracing.
