Container loading for bitumen drum exports

Tiger Bitumen loads filled steel drums into 20ft containers at its packaging facility in the Karachi Export Processing Zone, about 20 km from Karachi Port and Port Qasim. This page explains how a drum container is planned, loaded, secured and prepared for export, and what you need ready at the receiving end.

Loading process

How a bitumen drum container is loaded

Seven steps take a drum order from the agreed loading plan to a sealed container at the port. Each step is tagged to show whether it is stated Tiger Bitumen practice or the standard practice that applies to any containerised drum cargo.

Agree the loading plan

Drum size, number of drums per container, total net weight and number of containers are confirmed in your offer before filling starts.

TIGER BITUMEN

Check the empty container

Before loading, a container is checked for a valid safety approval plate, sound walls, roof and floor, working doors and seals, and a clean, dry interior.

Standard practice

Load from the front wall

Filled drums are placed upright, starting at the front wall and working toward the doors, so the load is spread along the floor rather than bunched at one end.

Standard practice

Secure the load

Gaps that would let drums move are filled or blocked, and the load at the doors is restrained so drums cannot shift or press on the doors in transit.

Standard practice

Inspection, where contracted

An agency such as SGS or Bureau Veritas carries out the inspection scope agreed in your contract. Buyers or their representatives are welcome to attend loading.

Weigh, declare and seal

The container’s verified gross mass is declared to the shipping line before loading on the vessel, as SOLAS requires for every export container, and the doors are closed with a numbered seal.
Standard practice

Haul to port and ship

The container moves to Karachi Port or Port Qasim for loading on a direct container vessel service, and the agreed shipping documents are issued.

Loading arrangements

How drums can be arranged in a 20ft container

Steel drums can be stowed in more than one way. The arrangement changes how much fits, how the load is secured and what equipment you need to unload. The arrangement used for your order should be stated in the loading plan.

… Side view · one tier · illustrative

One tier, floor-stood

How it works
Drums stand upright directly on the container floor in a single layer.
Consider
Simple to load and unload. Leaves some container height unused, so the payload limit must also be checked.
… Side view · two tiers · separator shown orange

Two tiers with separators

How it works
A second layer of drums stands on a suitable separator designed to distribute the load across the tier below.
Consider
Uses more container height. Stacking must be checked for drum strength, stability, total weight and safe unloading.
… Side view · palletised · illustrative

Palletised

How it works
Drums are secured on pallets and moved as pallet units using suitable material-handling equipment.
Consider
Can simplify forklift handling where the receiving facility supports pallets. Pallets add weight, cost and space requirements.

Drawings are side views at a common scale (drum 50 cm wide, 98 cm tall;
container internal height about 2.39 m). They show arrangement only, not

Weight distribution and securing

Keeping 180 kg drums still for the whole voyage

A container of drums is a heavy, dense load. It must be spread evenly along the floor and held so that no drum can slide, tip or press on the doors. The IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units (CTU Code) sets out the accepted principles.

Fill the gaps

Spaces between drums and walls are filled with dunnage, void fillers or blocking so drums cannot gather speed and strike each other or the walls.

Restrain the door end

The last rows are held by bracing, a gate or strapping so the doors never act as the restraint and open safely at destination.

Separate tiers

Where drums are stacked, a board or sheet between tiers spreads the weight across the drum rims and keeps the upper tier level.

Keep drums upright

Drums stand on their bases with lids on top, so the load is stable and closures stay accessible for inspection.

These are general principles from the CTU Code. The securing method for
your container is part of the loading plan agreed with your order.

Container utilisation

Why weight, not space, usually sets the drum count

Two limits apply to every drum container. Space: how many drums of a given height and diameter fit on the floor and in tiers. Weight: the maximum cargo the shipping line accepts in the container, and the road limits between the discharge port and your site.

A filled 180 kg drum weighs about 189 kg, and a filled 150 kg drum about 158 kg. With dense cargo like this, the weight limit is often reached before the container is full, which is why stacking in two tiers does not always add drums.

We check both limits for your route and state the drum count, net tonnes and number of containers in every quotation, so you can compare cost per tonne between drum sizes.

Weight check

Enter the cargo weight limit your shipping line or forwarder gives you for the route. The check divides it by the filled drum weight.

Example value, replace with yours
Drums within weight limit 105
Net tonnes of bitumen 18.9

Weight arithmetic only. It ignores space, stowage, securing material and road limits, so it is an upper bound, not a loading plan. Your quotation states the confirmed count.

Safe handling

Handling drums at loading and at unloading

A filled drum weighs close to 190 kg. These are the practical points that prevent damaged drums and injuries at both ends of the shipment. Follow your local regulations and the safety data sheet for your grade.

When loading

Standard practice

Heating and decanting drummed bitumen at site: see the handling and storage guide.

When unloading

Container loading questions

Planning a first shipment? Message the Export Manager.

It depends on the drum size, the arrangement, the cargo weight limit for your route and road limits at your destination. We state the drum count, net tonnes and number of containers in your quotation.

Tiger Bitumen ships drum orders in 20ft containers. Dense cargo such as bitumen drums usually reaches the weight limit well before it fills a larger container.

Yes. Buyers and their representatives are welcome to visit the facility and watch their drums being loaded. Arrange the visit through the Export Manager.

Third-party inspection by SGS, Bureau Veritas or a similar agency can be arranged. Tell us what the inspection should cover; the scope and cost are agreed in your contract.

Karachi Port or Port Qasim, both about 20 km from the packaging facility, on direct container vessel services.

Under the SOLAS convention, every packed export container must have its total weight verified and declared to the shipping line before it is loaded on a vessel. The declaration is part of export preparation.

Container unloading equipment able to handle drums of about 190 kg, space to store drums upright, and a plan to return the empty container within the shipping line's free time.
