ESI cut-off in shipping is the deadline for submitting Electronic Shipping Instructions to the ocean carrier. The carrier uses these instructions to prepare the bill of lading with the correct party names, cargo figures, and transport routing.
An FCL shipment from China requires accurate data from multiple sources, a submitter with carrier-system access, and a confirmed deadline in the correct time zone. Missing any of these can hold up the bill of lading or affect the planned sailing.
How Do ESI, CY, and VGM Cut-Offs Differ?
SI means Shipping Instructions. ESI (also written eSI) is the electronic version of the same submission. Some carriers show both an ESI and an SI field on the booking; these usually refer to the same deadline. Use the terms and dates on your booking confirmation.
| Cut-Off | Task Due | What to Confirm |
|---|---|---|
| ESI / SI | Submit the required shipping instruction data | Required fields, submission channel, authorized submitter, and documentation deadline |
| CY | Deliver the loaded container to the designated container yard or terminal | Gate-in location, receiving conditions, and latest gate-in time |
| VGM | Submit the Verified Gross Mass of the packed container | Verified weight, responsible party, submission channel, and weight deadline |
Gate-in, SI submission, and VGM declaration are separate tasks. Track them individually, even when their deadlines fall on the same day.
What Data Should You Prepare for ESI Submission?
The carrier’s SI form sets the required fields. Reconcile each entry against the shipment’s commercial records before submission.
Shipment Parties
Start with the names and addresses approved for the transport document:
- Shipper’s full name and address.
- Consignee’s full name and address.
- Notify party details, where required.
- Contact information and identification numbers requested by the carrier.
Confirm who should appear as the consignor and consignee, and check the spelling against the invoice. When a trading company or forwarder handles the shipment, the party on the transport document may differ from the party on the commercial invoice. Resolve any mismatch with the reviewer before data entry.
Cargo and Packaging
Compare the cargo entries with the commercial invoice and the final packing list:
- A specific, accurate goods description.
- Package count and package type.
- Gross cargo weight, with the unit stated.
- Cargo volume, where requested.
- Shipping marks and commodity codes, where required.
Distinguish cartons from pallets when checking package counts. Keep both packing levels in your working records and use the carrier’s required presentation. If the warehouse repacks or palletizes the cargo, confirm the revised count and weight with that facility before updating the SI.
Gross cargo weight and VGM have different scopes. VGM includes the cargo, packing and securing materials, and the container’s tare weight. Do not copy a cargo-only weight into the VGM field.
Booking and Container Details
A correct shipment total can conceal a wrong container allocation. For an ocean freight booking with more than one container, check each container’s data individually before comparing the combined figures:
- Booking or shipment reference.
- Ports and any required receipt or delivery locations.
- Vessel and voyage details requested by the carrier.
- Container numbers and seal numbers.
- Cargo quantities and weights assigned to each container.
If a container or seal number is still unavailable, tell the submitter immediately. Ask which fields must be complete at the initial deadline and whether the carrier permits a later update. Follow the confirmed procedure instead of entering an invented number.
Bill of Lading Requirements
Confirm the requested transport document, freight payment instructions, and recipient of the draft bill of lading. Include original-document quantities or other issuance instructions when the carrier’s form requires them. Give the reviewer any bank or payment instructions that affect the document wording before submission, and avoid copying release instructions from an earlier shipment without checking whether they still fit.
Upload certificates, declarations, or supporting files only when the carrier’s process requires them. For dangerous goods or destination-specific requirements, ask which additional SI fields and separate submissions apply before the deadline.
Who Submits ESI, and How Should You Confirm the Deadline?
For an FCL shipment, assign data preparation, review, and carrier submission before the final instructions change hands.
Assigning Preparation, Review, and Submission
| Role | Possible Owner | Task to Assign |
|---|---|---|
| Prepare | Supplier, exporter, buyer, or packing facility, according to the data | Supply accurate party, cargo, packing, and loading information |
| Review | Buyer, exporter, or appointed documentation coordinator | Resolve conflicting records and approve the instruction version |
| Submit | Booking party, forwarder, or another carrier-authorized shipment party | Enter the approved data, submit it, and follow up on missing fields or rejection |
Buying the goods doesn’t give you carrier-system access. Confirm that the named submitter can log into the carrier’s platform for your booking. After submission, ask for the submitted version, timestamp, and carrier acknowledgment. An email to the forwarder is not proof the carrier accepted the data.
Confirming the Deadline and Time Zone
Read the booking confirmation and the latest carrier notice together. Record:
- The ESI or SI deadline date and exact time.
- The named time zone or UTC offset.
- Any earlier handover deadline set by the forwarder.
- The contact responsible for communicating updates.
Where the forwarder sets an earlier handover deadline, use it to schedule supplier corrections and review before carrier submission. A new ETA doesn’t automatically move the SI deadline. Ask for the updated cut-off in writing, and if the booking confirmation and portal show different times, have the booking contact resolve the conflict before relying on either.
Combining Data From Multiple Suppliers
Use one worksheet for consolidated shipping from China, with a row for each supplier’s goods. Record the supplier reference, description, final packing figures, weight, and container allocation. Reconcile the combined totals with the final loading record, using consistent units and the warehouse’s final packing figures.
Give one person control of the worksheet and send the reviewer-approved version to the submitter with its revision date. When a supplier changes a figure after approval, update the combined record and route it back through review before resubmitting. A global freight forwarders handling the booking can serve as that single point of control when no one on the buyer’s team is based near the suppliers.
What Should You Do If ESI Is Late, Incomplete, or Changed?
Contact the booking forwarder or carrier documentation team immediately. State the booking reference, affected fields, current submission status, and corrected information.
- Ask whether the carrier can still accept the initial submission or amendment for that booking.
- Confirm the permitted channel, required information, and deadline for the correction.
- Check applicable charges and any effect on the transport document, manifest, or sailing plan.
- Obtain confirmation that the carrier processed the correction, and retain the revised instruction or document version.
When multiple suppliers contribute data to one SI, having a single freight forwarder coordinate the records catches mismatches before submission. Foresmart’s sea freight team handles FCL bookings and export documentation, including carrier-submission coordination for multi-supplier shipments. Send your booking reference, cut-off notice, and supplier records so the team can reconcile the China-side data and submit approved instructions on time.
Frequently Asked Questions
Does Submitting ESI Mean I Will Receive an Electronic Bill of Lading?
No. ESI describes how you submit shipping instructions. An electronic bill of lading, or eBL, is a separate transport-document choice. Confirm the requested document type and the carrier’s arrangements for issuing it.
Can One ESI Submission Cover More Than One Container?
Some carrier systems accept multiple containers in one SI submission. Ask the submitter whether your booking needs combined or separate entries, especially when containers load at different facilities or carry goods for different consignees.
What Errors Should I Watch For on the Draft Bill of Lading?
Compare the draft against the approved instructions before confirming it. Common errors include transposed consignee and notify-party details, rounded cargo weights that no longer match the packing list, and freight-payment terms carried over from a previous booking. Report discrepancies through the carrier’s correction process before the BL is finalized.
