UNDERSTANDING THE SERVICE
What Is Container Loading Supervision?
Between the inspection you paid for and the door being sealed, your cartons are handled by people you never meet, in a yard you never see. Our inspector is there for the whole load: checks the empty container for damp and damage, counts every carton against the packing list, watches stacking, bracing and weight distribution, and records the seal number.
An importer's 3,000 wine glasses passed PSI. Nobody watched the load — factory workers stacked heavy ceramic tiles on top of them. The damage was found on arrival. Transit damage: $67,000.

COMMON CONCERNS
Honest Answers to Tough Questions
My factory handles loading — why pay extra?
Nobody in that yard carries the cost of damage found after the door closes. Our inspector doesn't load the container — they count it, photograph it and record the seal number.
Isn't this covered by insurance?
The inspector found improper stacking that would have caused $30K in transit damage.

Honest Answers to Tough Questions

Nobody in that yard carries the cost of damage found after the door closes. Our inspector doesn't load the container — they count it, photograph it and record the seal number.

Marine cargo insurance almost always excludes damage caused by improper loading, stacking, or bracing unless it was documented by a third-party supervisor at the time. Without CLS, insurers routinely deny loading-related claims — our timestamped report is exactly the evidence they require.

Frequently Asked Questions

Most CLS take 4–8 hours depending on container size and cargo quantity. Inspector stays until loading is complete and container is sealed.

Yes — and we recommend it. PSI confirms your goods are made correctly; CLS confirms they're loaded correctly. Together they close the two biggest gaps before your container leaves the country, and bundling the two saves you on the combined fee.

The inspector halts loading on the spot, documents the issue with photos, and requests a correction (for example, a restack or added bracing) before work continues. You're notified immediately so you can decide how to proceed — problems are fixed before the container is sealed, not after damage occurs.

Yes. The inspector counts every carton loaded and reconciles the total against your packing list, so short-shipments or over-shipments are caught and recorded in the report before the seal goes on.

Usually not. Marine cargo policies commonly exclude damage from improper loading, stacking, or bracing unless a third-party supervisor documented conditions at the time. CLS gives you the timestamped, photographic evidence insurers require to honor a claim.

What's Next?

Always pair CLS with PSI for complete pre-shipment protection. Add DUPRO for orders above 1,000 units.
