If labeling errors are the main risk, focus on C1 and ask how KIZ is linked to a specific item/order and verified after extra packaging.
For liquids, fragile goods or other complex categories, C2 matters more than the number of packaging line items. Verify leak protection, cap/dispenser fixation and category-specific handling.
If returns are frequent, focus on C3: inspection, condition recording, repacking/relabeling and the return to sellable stock.
For short FBS cycles, C4 combines handoff frequency and automation. Dispatch frequency, cycle time and integrations are more informative than a generic “fast” claim.
For budget planning, C5 measures cost transparency, not the lowest price.
If errors and penalties are critical, C6 covers material responsibility, compensation, SLA and traceability.
