Window and Door Export Packaging and Container Loading Guide

1. Design packaging from the unit schedule and journey

Begin with unit mark, dimensions, weight, centre of gravity where relevant, glass condition, projecting hardware, finish sensitivity and whether the unit ships glazed or knock-down. Add the route: factory handling, inland haulage, terminal transfers, sea voyage, destination storage, unloading equipment and route to the opening.

A standard carton may be suitable for accessories but not for a large glazed assembly. A strong rack may protect the unit yet be impossible to move through the site gate. Record the full handling chain before approving the pack.

2. Prevent glass, frames and hardware from loading each other

Do not let heavy glass, frames and accessory boxes move as one uncontrolled mass. Use a designed support and separation route that avoids point contact at glass edges, abrasion on finishes, distortion of frames and loose hardware impact.

Protect drainage paths, tracks and operating hardware without creating a pack that site teams must dismantle destructively. Identify any transport braces that must be removed before operation and show the removal method.

• Stable unit orientation and supported bearing points
• Edge and corner protection compatible with the finish
• Separation between glass, frames and loose components
• Positive restraint against movement in expected transport directions
• Accessible lifting and fork points
• Clear warnings for transport braces and fragile interfaces

3. Check whether wood packaging is regulated

ISPM 15 covers many forms of raw-wood packaging that can carry pest risk, including crates, boxes, dunnage and pallets. It also lists exemptions for certain processed wood materials and thin wood. Do not reduce compliance to the word “fumigated”; identify the material, destination requirement, approved treatment or exemption and valid mark route.

The IPPC states that approval to apply the ISPM 15 mark comes from a national plant protection organisation or an officially audited and mandated organisation. A self-made mark or supplier statement is not equivalent.

Destination check: Confirm current import requirements with the destination’s plant-protection and customs authorities before packing, because the international standard and local enforcement route are not the same question.

4. Make the container a load-control system

The IMO/ILO/UNECE CTU Code addresses packing and securing across the intermodal chain. It is non-mandatory global guidance, but it is a useful review framework: cargo distribution, blocking, bracing, lashings, package strength, container condition and safe unpacking all interact.

A photograph of a closed door does not prove secure loading. Review the empty container condition, floor and lashing points, package positions, weight distribution, void control, restraint method and door-end risk. The packer must use cargo-specific calculations and competent judgement rather than copying a photograph from another shipment.

1. Inspect and record the empty container, number and condition.
2. Confirm package weights, positions and handling orientation against the load plan.
3. Place and secure packages using the approved blocking, bracing and restraint method.
4. Prevent concentrated loads, unstable stacks and movement into the doors.
5. Keep labels and unloading references visible where practical.
6. Record intermediate stages before later cargo hides the securing method.
7. Confirm final closure, seal number and release documentation.

5. Treat moisture control as a calculation—not a bag count

Temperature changes can cause moisture to condense inside a container. The risk depends on cargo and packaging moisture, route, season, ventilation, duration and how vapour can reach cold surfaces. Desiccants and barriers are controls only when selected as part of that system.

Avoid claims that a fixed number of desiccant bags makes every load safe. Define packaging moisture condition, barrier continuity, desiccant type and placement, ventilation decision, storage limits and inspection evidence with the logistics and packaging team.

• Dry condition before packing
• Moisture-sensitive materials and finishes
• Barrier and wrap continuity
• Desiccant specification and safe placement
• Ventilation or sealed-pack decision
• Route and seasonal exposure
• Destination storage and unpacking instructions

6. Load for unloading and installation

Connect every package to the project, building, floor, room or opening mark as appropriate. Plan the load backwards from the destination: items needed first should be accessible without unsafe rehandling, subject to the load’s stability and securing design.

The unit label should reconcile with the approved schedule, packing list and site plan. Use the installation checklist to confirm what the receiving team must inspect before moving or installing the frame.

7. Build a loading evidence sequence

Photographs should answer a later question, not merely show activity. Capture the empty unit, container number, package labels, staged positions, restraints before concealment, weight or seal records where applicable, completed load, doors and seal number.

Keep the load plan, packing list and photo index under the same shipment reference. If damage occurs, receiving evidence should connect the container, seal, package, opening mark, overall condition and close-up damage before disposal or repair changes the scene.

• Empty container and identifying number
• Package condition before loading
• Labels and opening marks
• Loading order and intermediate restraint
• Final blocking, lashing and door-end condition
• Seal number and closed doors
• Receiving container and seal
• Damage overview, detail and affected item identity

8. Read insurance cover and exclusions before shipment

Do not assume that an Incoterms rule or the word “insured” covers every loss. ICC notes that Incoterms allocate buyer and seller responsibilities, costs and risks; insurance obligations and levels differ by rule, while the actual policy contains its own subject matter, limits, deductibles, exclusions, notification and evidence requirements.

Review breakage, moisture, inadequate packing, delay, war or strikes, storage, inland legs and claims procedure with an insurance professional. Record who buys the cover, whose interest is insured, the insured value and the deadline for notice and survey.

Claim readiness: Before loading, ask whether the planned photographs, packing records and receiving procedure would satisfy the actual policy and carrier claim requirements—not a generic checklist.
