A mixed order — carburetors, brake pads, shock absorbers, maybe a few crated motorcycles — is where loading discipline pays. Freight damage is rarely about strength; it is about physics nobody planned for. This guide covers the decisions that protect the cargo and the margin.

Cartons or pallets?

• Loose cartons maximize cube — typically 10–15% more units per container. They suit dense, non-fragile goods: brake pads in master cartons, hardware, chains.
• Pallets cost cube but cut handling damage dramatically, speed unloading (hours to minutes), and enable warehouse racking at destination. They suit carburetors (fragile floats and bowls), suspension (bent stanchions from stacking pressure), and anything retail-packaged.

Our default for mixed orders: palletize everything fragile, loose-load the dense goods, and block the pallets against forward motion — the longitudinal stop is what most loading plans forget.

Weight distribution: the unglamorous killer

Two rules prevent most structural trouble. First, heavy over light — never stack dense cartons (pads, discs) on top of boxed shocks or carburetor cartons; crush damage shows up as claim photos, not at loading. Second, front-to-rear balance: a container with all mass at the nose can exceed axle weight limits at inspection and cost a re-weigh and re-load at the port. Plan gross weight per zone before loading starts.

Moisture: the silent claim

A container crossing the equator cycles through dew points that will rain inside a sealed box. Protections that work: desiccant (roughly 1 kg per container minimum, more for humid routes), kraft or VCI paper between metal parts and carton walls, and never loading damp cartons — moisture sealed inside stays inside. Cardboard directly on a steel container floor wicks condensation; a thin ply layer under the load is cheap insurance.

Documentation alignment

Customs delays cost more than damage. Three alignment checks before the container doors close:

• Carton marks match the packing list item by item.
• Gross and net weights on the list match the scale — inspectors weigh containers.
• Hazard-adjacent items (aerosol cleaners, lithium batteries) are declared and segregated — one undeclared item can hold the whole box.

Damage patterns worth pre-empting

The recurring claims in our category: carburetor float bowls cracked by overstacking, shock stanchions bent by strapping tension against the box (strap the pallet, not the product), disc rotors with corner dings from loose handling, and corroded fasteners from humid-route condensation. All four are loading-plan problems, not product problems.

We photograph every container we load — floor to ceiling, before the doors close. It takes four minutes, and it has settled more claims disputes than any word in any contract. Ask your suppliers if they do the same; if they do not, that photo is your evidence, taken by you at the factory gate.
