Export Packaging for Sea Freight: A Practical Checklist for Indian Exporters

Export packaging for sea freight should protect the product through the entire journey: factory handling, road transport, consolidation, ocean movement and final delivery. A carton that survives a local courier trip may not survive repeated handling, long storage or pressure from other cargo. The right starting point is a written packing specification, agreed before the order goes into production.

This guide is for Indian exporters preparing ordinary, non-dangerous goods for an initial shipment. It explains how to turn a vague instruction such as ‘use export-quality packing’ into measurable decisions. The examples are illustrative planning exercises, not laboratory test results or promises of damage-free transport.

1. Map the journey before choosing packaging

Start with the route rather than the box. Will the goods move as less-than-container-load cargo, known as LCL, or in a full container, known as FCL? Will a warehouse receive loose cartons, palletised cartons or crates? Who will load and unload them? Ask your forwarder which handling points are expected and ask the buyer what their receiving team can accept.

For an LCL shipment, plan for your packages to travel alongside other consignments and pass through consolidation facilities. For an FCL shipment, concentrate on how the goods will be distributed and secured inside the container. Neither arrangement removes the need for suitable packaging. A sealed container does not make an unsupported stack stable or turn a damp carton into a dry one.

Write down the plausible failure modes. A glass item may chip when neighbouring pieces touch. A metal component may develop surface corrosion. A textile carton may be crushed or absorb moisture. A heavy machine part may need engineered support and lifting provisions. Each risk calls for a specific control; adding more layers of stretch wrap does not solve every problem.

Also record the destination conditions you can establish: storage outdoors or indoors, delivery appointment requirements, forklift availability and maximum acceptable package weight. If the buyer cannot provide an answer, identify that gap before treating your packing plan as final.

2. Turn ‘export quality’ into a written packing specification

A useful specification tells the supplier what to make, the inspection team what to check and the buyer what to expect. Keep it short enough to use on the packing floor. Attach a photo or drawing of the approved arrangement and give the specification a version number so that everyone works from the same instructions.

Agree who owns the packing materials and inspection cost. A merchant exporter should clarify whether the supplier’s price includes export packing or only the standard domestic pack. Obtain approval for substitutions: a different carton grade, thinner divider or alternative pallet should not appear on dispatch day without review.

Use your export product brief as the starting document. Add a packing section that identifies fragile areas, product finish, contamination concerns and the buyer’s presentation requirements.

3. Choose cartons, pallets and crates for the actual load

Carton selection involves more than wall count. Discuss the filled carton weight, the expected stack, storage duration and environmental exposure with the packaging supplier. Ask for the relevant performance information and an explanation of why the proposed construction fits your shipment. Do not invent a universal carton strength that supposedly works for every export product.

Internal protection should stop the product moving and prevent contact at vulnerable points. Dividers may separate individual items; shaped supports may hold a component in place. Cushioning should fit the product, not simply fill visible space. Check that the closure method remains practical for inspection and that resealing does not leave the package weak.

For palletised goods, confirm pallet footprint, load capacity, fork access and the buyer’s handling equipment. Keep the load arranged consistently and avoid unsupported carton overhang. Check whether wrapping, straps, corner protection or other restraints are appropriate for your design. Obtain specialist advice for unusually heavy, tall or unstable loads.

Wood packaging needs a separate compliance check. IPPC guidance on ISPM 15 covers regulated wood packaging and approved treatment and marking arrangements. Check applicability and the destination’s requirements with an authorised packaging provider; do not add an IPPC mark yourself. Keep procurement evidence for the pallets or crates supplied.

Crates can be appropriate for some products, but they also add weight and volume. Specify how a crate supports the item, how it will be opened and how lifting will take place. A large wooden box around an unsecured product is still an unsecured product. Discuss access for examination without destructive unpacking where practical.

4. Plan moisture protection and cargo securing together

Inspect the product and packing materials before sealing. Packaging a damp product or using wet timber can introduce moisture at the beginning of the journey. Review drying, clean storage and packing conditions with the supplier. Document the condition rather than relying on an instruction that everything should be ‘dry enough’.

Moisture-control materials need to suit the product and enclosure. Ask the packaging specialist how a barrier, liner or desiccant system should be selected and used. Do not assume a handful of sachets can protect an entire container, or that a tightly wrapped pallet is automatically protected against condensation. Some materials and finishes require a different approach.

Photograph the approved inner arrangement before the carton is closed. This makes repeat packing easier and provides evidence of what was supplied. Capture the final package and any protective additions as well. Store these images against the order reference so they can be retrieved during a receiving query.

For container packing, use trained personnel to assess distribution, restraint and safe unloading. The IMO/ILO/UNECE CTU Code is a non-mandatory global reference for packing and securing cargo transport units. A package checklist does not replace a cargo-specific securing plan or an assessment by a competent packer.

5. Measure finished packages and reconcile the documents

Measure the outside of the completed package, including pallet height and any projections. Do not send the forwarder bare-product measurements when you intend to ship packed goods. Provide the number of packages, their dimensions and the actual gross weight. State whether packages are stackable and describe any handling restrictions.

For a rectangular package measured in metres, volume is length × width × height. A carton measuring 0.60 × 0.40 × 0.40 metres occupies 0.096 cubic metres. Fifty such loose cartons total 4.8 cubic metres before any change in the final palletised arrangement. Freight billing may use a different minimum, rounding rule or weight/measurement basis, so obtain that basis in writing.

Keep net weight and gross weight distinct. Net weight describes the goods; gross package weight includes its packaging. A packed-container verified gross mass is a separate measurement. IMO’s VGM guidance explains the shipper’s responsibility and the permitted verification approaches under SOLAS. Coordinate the responsible party, approved method and submission deadline with the forwarder rather than substituting the packing-list total for container VGM.

Shipping marks should help the receiving team identify packages without guessing. Agree an order reference, package sequence, destination or consignee reference where appropriate, and necessary handling information. Keep marks consistent with the packing list. Product labelling, country-of-origin statements and regulated transport labels require their own review; a commercial carton label does not establish compliance.

Use the export documents checklist to reconcile order references, descriptions and package totals before releasing the final paperwork.

6. Worked example: 600 non-fragile textile items

Suppose an exporter plans to ship 600 textile items in 50 cartons, with 12 items per carton. Each finished carton measures 60 × 40 × 40 centimetres and weighs 9 kilograms gross. The loose-carton planning totals are therefore 4.8 cubic metres and 450 kilograms gross. These invented numbers illustrate the method; they are not a freight quotation.

The buyer then requests pallet delivery. The exporter should ask the packing provider for the proposed number of pallets, their loaded dimensions and the revised gross weight. Simply sending the original loose-carton figure can understate space because the pallets, wrap and gaps alter the final load. The forwarder needs the completed arrangement to quote accurately.

Before approval, the exporter checks the inner bags, carton closure, label sequence and whether the buyer can handle the proposed pallet size. The supplier confirms that packing cost is included. Photographs of one open carton and a completed pallet are approved, then recorded as the packing standard for the remaining goods.

The important decision is not ‘cartons versus pallets’ in isolation. It is whether the agreed arrangement protects the product, fits the receiving process and is accurately described in the shipping instructions. Feed the final packing cost and freight information into your export selling-price calculation.

7. Pre-dispatch export packaging checklist

• The buyer has approved the packing format and receiving constraints.
• The supplier is using the correct packing specification and materials.
• Product count matches carton count and the order quantity.
• Inner supports protect vulnerable surfaces and restrict movement.
• Completed packages have been weighed and measured.
• Package numbers and shipping marks match the packing list.
• Wood-packaging requirements have been checked where applicable.
• Handling and stacking restrictions have been communicated to the forwarder.
• The packing provider has assessed container securing where relevant.
• The VGM process and deadline have been assigned where applicable.
• Inspection photographs and supplier records are stored with the order.
• Someone is named to approve any last-minute packing change.

Run this review while changes are still possible. Finding a missing pallet requirement after the truck arrives creates pressure to improvise. If a check fails, identify who can correct it and when, then update the booking plan if necessary.

Frequently asked questions

What is the best export packaging for sea freight?

There is no single best material. Choose an arrangement based on the product, its vulnerability, package weight, handling route and buyer requirements. Use supplier performance information and appropriate testing or specialist review to justify the decision.

Is stretch wrapping enough for export cartons?

Stretch wrap can help unitise a suitable load, but it does not replace carton strength, inner protection or cargo restraint. It also should not be treated as a complete moisture-control plan without assessment.

Do all wooden export pallets need the same treatment?

Check the wood-packaging standard’s scope, the material and destination requirements with an authorised provider. Ask for evidence of the applicable treatment and marking rather than assuming an ordinary locally purchased pallet is acceptable.

Can I quote freight using product dimensions?

Provide final packed dimensions and weight. If packing is not finished, identify the figures as estimates and agree when the quotation will be revised. Changes in package size, weight or stackability can affect cost.

Does packaging remove the need for cargo insurance?

Packaging and insurance address different questions. Discuss the shipment’s protection and policy terms with a qualified insurer or adviser. Do not assume that good packing guarantees a claim will be covered.
