What Is a Container Loading Check?
A Container Loading Check (CLC), also known as Container Loading Supervision (CLS), is an on-site inspection conducted at the factory or warehouse while goods are being loaded into a shipping container. An independent inspector verifies that the correct products, in the correct quantities, are loaded in the right sequence and condition — and that the container itself is suitable for transport.
This inspection is the last opportunity to verify a shipment before it begins its journey. Once a container is sealed and leaves the factory, any issues with quantity shortfalls, loading damage, wrong products, or container condition become extremely difficult and expensive to resolve.
When Should You Schedule a Container Loading Check?
A CLC should be scheduled on the day of loading, with the inspector present from the moment the empty container arrives until it is sealed with a security seal. For large orders spanning multiple containers, an inspector should be present for each container load. Some buyers combine a container loading check with a pre-shipment inspection on the same day to maximize efficiency.
What Does a Container Loading Check Cover?
- Container condition inspection — Before any goods are loaded, the inspector examines the empty container for structural damage, holes, rust, water stains, odours, previous cargo residues, and proper functioning of doors and locking mechanisms. The container's age, cleanliness, and suitability for the cargo type are assessed.
- Quantity verification — Every carton loaded is counted and reconciled against the packing list. The inspector verifies total carton count, pallet count (if applicable), and random carton weight checks against declared weights.
- Product and carton identification — Shipping marks, carton labels, and product assortments are verified against the purchase order. The inspector confirms the right products are going into the right container.
- Loading method and sequence — The inspector monitors how goods are arranged in the container, checking for proper stacking, bracing, and securing. Fragile or heavy items must be positioned correctly to prevent transit damage.
- Damage prevention — Any pre-existing damage to cartons or products is documented before loading. The inspector watches for rough handling, improper stacking, or conditions that could cause damage during transit.
- Container sealing — The inspector records the container seal number and verifies it matches shipping documents. The sealed container is photographed for the record.
