Overview
Poor packaging refers to a condition where the cargo is not properly packed, secured, waterproofed, moisture-proofed, cushioned, or rust-prevented to withstand the normally expected transportation environment.
In maritime transport, vibration, shaking, transshipment, cargo handling, temperature and humidity fluctuations, condensation, and long-term storage occur. Therefore, packaging tailored to the nature, weight, shape, and transport route of the cargo is required.
Poor packaging is a common issue that often leads to exemption from liability under the carrier's responsibility or marine cargo insurance. If the cause of damage is not an external accident but is judged to be due to insufficient packaging strength, inadequate securing, lack of waterproofing, moisture prevention, rust prevention, or insufficient cushioning material, claims may become difficult.

Correct Understanding |
Practical Notes |
| Clean B/L means no poor packaging |
A Clean B/L only indicates no visible external abnormalities and does not guarantee the appropriateness of interior packaging |
Records of internal securing, cushioning material, and moisture-proofing material are important |
| Wooden crate packaging guarantees no issues |
Even wooden crates can fail as poor packaging if strength, securing, moisture-proofing, rust prevention, or center of gravity measures are insufficient |
Check if the design matches the weight and shape of the cargo |
| No survey means no poor packaging |
Poor packaging can be an issue even without a survey, based on photos, external condition, and internal damage status |
Preserve the actual cargo and packaging materials immediately after an incident |
| Insurance always covers damage caused by poor packaging |
Marine cargo insurance often excludes damage caused by insufficient or improper packaging |
Keep evidence of packaging before shipment |

Practical Points
Poor packaging is a typical exemption issue in marine transport. If there are no external accidents and damage is judged to arise from insufficient packaging strength, securing, waterproofing/moisture protection, cushioning, or rust prevention, recovery via carrier liability or marine cargo insurance may be difficult.
When poor packaging is alleged, it is necessary to provide documentation showing that the packaging met the standard required for normal transport or that the damage was caused by an external accident, not packaging.
Packing is not just a shipping operation; it is a crucial risk management factor directly linked to marine cargo insurance, carrier liability, and accident recovery potential.
