Preparing Your Warehouse for Export Container Loading: A Shipper’s Checklist

1. Work Backward From the Current Export Receiving Window

Confirm the current booking, ocean carrier, return terminal, container size and type, and loading address before arranging the move.

Ask the party managing the booking to verify the earliest receiving date, cargo cutoff and any separate documentation or VGM deadlines. Keep the trucker informed when those instructions change.

Plan around the time needed for cargo preparation, loading, securing and loaded pickup. Do not assume that a published cutoff leaves enough time for a last-minute warehouse departure.

For the distinction between the opening and closing of the receiving window, read our ERD versus cargo cutoff guide.

2. Confirm Cargo Readiness and Shipment Information

Have the loading supervisor confirm when the actual shipment will be ready. A planned production-completion time is not the same as cargo being packaged, counted and available at the loading area.

Before arrival, confirm:

• The cargo description and any special handling requirements.
• Expected package or pallet count, dimensions and cargo weight.
• Whether the freight is palletized, crated or floor-loaded.
• The loading address, entrance, working hours and site contact.
• Who will resolve count, packaging or booking discrepancies.
• Who manages shipment documentation and any required export filings.

Check with your freight forwarder or other responsible party about the commercial invoice, packing list and destination-specific documents. Requirements vary; a certificate of origin is not a universal requirement for every shipment.

If dangerous goods or temperature-controlled cargo are involved, identify the specialist requirements before scheduling. Confirm carrier acceptance and the necessary arrangements rather than assuming a standard dry-container plan applies.

3. Prepare Packaging and Stage the Loading Sequence

Use packaging suitable for the cargo and its planned transport conditions. Check for damaged cartons, unstable pallets and packaging that may not withstand handling or stacking.

Where regulated wood packaging is used, confirm the destination’s requirements and the applicable treatment and marking rules. ISPM 15 does not mean every wood-based product needs a heat-treatment stamp; exemptions and approved treatment methods matter. Consult USDA APHIS export wood-packaging guidance.

Stage freight so the loading team can identify the shipment and follow its loading plan without searching through unrelated inventory. Keep aisles and pedestrian routes clear.

Photographs and counts can help document the shipment, but they do not replace a suitable packaging and cargo-securing plan.

4. Match the Facility, Crew and Equipment to the Job

Confirm that the entrance, approach and loading position can accommodate the tractor, chassis and container. Tell the carrier about tight turns, restricted gates, overhead obstructions or other access limitations before dispatch.

Assign an available loading crew and suitable handling equipment. Confirm who operates the equipment and who supervises the work. Do not assume the drayage driver supplies warehouse labor or loading equipment.

Have trained personnel verify that the loading arrangement, dock equipment and vehicle-securement procedures are appropriate for the work. Follow the facility’s safety procedures and applicable requirements.

The planned container size does not by itself establish that a particular forklift, dock plate or loading method is suitable.

5. Agree on Live Loading or a Container Drop

With live loading, the driver generally remains while the warehouse loads the container. Confirm the expected loading duration, included waiting allowance and what happens if the work takes longer.

With a container drop, confirm that the carrier has agreed to leave the equipment and that the facility has an acceptable placement location. Establish the planned loaded-pickup time and any access restrictions.

A drop does not mean the container or chassis can remain indefinitely without charges. Equipment time, storage and other charges depend on the applicable agreements.

Review our export container detention and per diem guide when planning how long equipment may remain outside the port.

6. Check Container Condition Before Loading

Have designated personnel check the container number, size and type against the shipment instructions. Follow established inspection procedures for visible damage, cleanliness, moisture, odors, door condition and other cargo-suitability concerns.

If a concern is found, pause loading and contact the responsible supervisor, carrier or equipment provider for instructions. Record the condition and any authorization received. Do not assume replacement equipment is immediately available.

Do not enter a container or close its doors around a person merely to perform a light-leak check. Entry and inspection must follow the facility’s safe procedures, including assessment of ventilation and other hazards.

Use an inspection process appropriate to the shipment. A general checklist does not replace specialized security, food, dangerous-goods or other cargo requirements.

7. Follow an Appropriate Loading and Cargo-Securing Plan

The loading team should work from a plan that addresses package strength, stacking, weight distribution, concentrated loads and cargo movement during transportation.

Confirm that the planned shipment is suitable for the container and the road move. Container capacity and a verified container weight do not by themselves establish compliance with highway or axle-weight limits.

Have competent personnel select and apply suitable securing methods. Do not treat generic instructions to add straps, dunnage bags or nailed blocking as a complete securing plan.

The IMO/ILO/UNECE CTU Code provides guidance on packing and securing cargo for intermodal transportation. It is a code of practice, not a substitute for applicable legal requirements or shipment-specific expertise.

8. Plan the VGM, Seal and Shipment Records

Decide in advance who is responsible for obtaining and submitting the Verified Gross Mass and meeting the applicable deadline.

VGM is the verified gross mass of the packed container, including its contents and container tare mass. Under the IMO framework, it can be determined by weighing the packed container or using an approved calculation method that includes the relevant cargo, packaging and securing materials plus container tare mass.

Do not substitute an estimated cargo weight for VGM. Read our VGM guide and the IMO verified gross mass guidance for more detail.

Before closing and sealing, complete the required checks under the shipment’s procedures. Confirm the applicable seal specification, who supplies and applies it, and who records and communicates the seal number.

Where permitted, retain photographs of container condition, loading stages and the final seal. Identify the container and shipment clearly. A driver’s signature should reflect the record being acknowledged; it does not automatically verify concealed cargo counts, packing quality or regulatory compliance.

9. Send Dispatch a Clear Loaded-Ready Handoff

Notify dispatch when loading and the required warehouse checks are complete. Do not report the container ready while work that prevents collection is still unfinished.

Provide:

• Container number and booking reference.
• Exact collection location and site contact.
• Confirmed loaded-ready time and collection hours.
• Seal number and required shipment records.
• Weight information needed for transport planning.
• Any damage, access issue or change affecting collection.

The party managing the booking should separately confirm the current return terminal, receiving window, acceptance status and required submissions. Loading completion is not the same as terminal acceptance.

If the booking or loading plan changes, notify the trucker promptly so the move can be reassessed before dispatch.

Final Export Container Loading Checklist

Assign a responsible contact for each checkpoint. Resolve open items before the relevant stage of the move rather than relying on assumptions.
