General Labeling Requirements
- If the secondary or outer package is being reused (allowed if the package is intact and has been disinfected), all irrelevant labels and markings must be removed.
- Use durable, standard-sized (4 x 4) labels.
- IATA allows half-size labels when packages are too small for standard-sized labels
- DOT does NOT allow half-size labels
- Affix hazard labels securely to one side
- Do not overlap labels or box edge
