During global container operation and turnover, damage is almost inevitable and will directly affect normal liner service. For cost control, correct container usage to minimize damage and timely repair to quickly restore service are the two core points of container management.

This article systematically explains container damage classification, correct usage rules, daily maintenance, and repair standards to help you extend container life and reduce operating costs.

1. Two Main Types of Container Damage

① Abnormal Damage

Caused by external impact, improper operation, or cargo factors:

• Collision, truck accidents, lifting drops

• Improper loading/unloading

• Overweight, unbalanced loading, sharp cargo scratches

• Leakage, pollution from liquid/dusty goods

• Damage to reefer units due to wrong operation

This type of damage is preventable and accounts for most repair costs.

② Natural Damage

Normal wear during long-term use:

• Body rust, paint aging

• Floor aging, delamination

• Minor scratches not affecting cargo safety

• Natural wear of labels, seals, and small components

• Normal aging of reefer parts

This type can be delayed through routine inspection and maintenance.

2. Correct Container Usage – Key to Reduce Damage

① Strictly Control Loading Weight

• Never exceed the MAX PAYLOAD marked on the container door.

• Overweight causes: floor breakage, bottom frame deformation, top beam fracture, safety risks.

② Evenly Distribute Load

• Avoid heavy loads concentrated on one end/side.

• Use wooden mats to disperse pressure for heavy machinery/steel coils.

③ Standard Forklift & Loading Operation

• Do not drag cargo directly on the floor.

• Reserve gaps: top \20mm, bottom \100mm.

• Use dunnage to protect floors and allow fork withdrawal.

④ Prevent Pollution & Leakage

• Liquid/pollution goods at the bottom; separate with plastic/canvas.

• Cover the floor to avoid permanent stains; floor replacement costs hundreds of dollars.

⑤ Secure Cargo Properly

• Use lashing materials to prevent shaking and collision during transit.

⑥ Reefer Container Special Rules

• Pre-cool goods properly; do not cool down inside the container.

• Keep vents unblocked; leave top gap for air circulation.

• No spoiled goods to avoid cross-contamination.

• Keep 220/380V power connected during transit.

• Report unit faults to depot/agent immediately.

⑦ Special Cargo Notice

Coiled steel, marble, scrap, logs, ore, sugar, starch, etc., require extra protection and comply with special handling rules.

3. Container Daily Maintenance & Repair Management

Daily Maintenance Tips

• Clean oil stains immediately to avoid floor penetration.

• Conduct routine inspections when entering depots.

• Repair small damages in time to avoid expansion.

Repair Management Rules

• Strictly prohibit unqualified repair workmanship.

• Do not use substandard repair materials.

• Choose certified repair stations.

Two International Repair Standards

• IICL Standard: High-standard, widely used by major leasing companies.

• CARGOWORTHY Standard: Cargo-worthy level, commonly used by shipping lines.

Operation Standardization

• Standardize agent operation processes.

• Certify and supervise users and depots.

• Establish complete inspection & record systems.
