Packaging — FBA Carton & Labeling Checklist (NSKU, Case Pack, Warnings)
6 min Read
TL;DR
- Define carton marking, case pack rules, barcode placement.
- Suffocation warnings and master carton specs before production.

Amazon inbound mistakes = delays, relabel costs, returns spikes. Get your carton and label specs right from day one.
Why This Matters
FBA is unforgiving. A scan failure or wrong box size means expensive prep fees or rejection. The supplier needs a strict diagram.
What to ask suppliers
- Q1Can you follow an exact label placement diagram?
- Q2Do you have barcode print QC (scan test)?
- Q3Can you provide carton drop test evidence?
Red Flags
- “We print labels for you” but no scan test process
- No case pack discipline (mixed SKUs)
- Carton strength spec not defined
Step-by-Step Verification Checklist
- 1NSKU/FNSKU barcode size + quiet zone

- 3Case pack qty fixed (no mixed)

- 7Inner packaging protection spec
- 8Carton sealing method + tape width
- 9Drop test requirement (ISTA 1A or simple 6-face)
