The draft B/L starts here
What the shipping instructions say usually becomes the draft B/L word for word, so errors travel straight onto the document. Carriers also use SI data for advance cargo filings that some countries require before loading, which is why many now ask for HS codes and full party details. Typing the consignee's name the way it appears in customs records saves corrections later.
Late instructions and amendment fees
The SI deadline appears on the booking confirmation and often falls on or before the cargo cut-off. Instructions that arrive late can leave a container off the manifest even though it sits in the terminal, and the box may be rolled. Some carriers accept late SIs for a fee. Changes made after the bill is issued become amendments, which some carriers also charge for.
Records the carrier compares before loading
The carrier compares several records before loading. Container and seal numbers on the SI should match what the terminal logged at gate-in, the equipment should match the booking, and the weight should square with the VGM submission, which many carriers take separately. When the records disagree, the carrier may hold the container back until someone confirms which version is right. Checking the gate-in record before submitting helps prevent these mismatches.
Example
Before the documentation cut-off, a forwarder submits shipping instructions listing HLBU2456904, its seal number, 1,200 cartons of furniture, the consignee and notify party, and a request for a sea waybill.

Questions
What does Shipping Instructions mean?
Shipping instructions (SI) are the details a shipper or forwarder sends the carrier after booking so it can prepare the bill of lading: parties, cargo description, packages, weights, container and seal numbers, and the B/L type and freight terms wanted.
Is the shipping instruction the same as the bill of lading?
No. The SI is the shipper's input, and the B/L is the carrier's document built from it once the cargo is received. A draft B/L usually comes back for review in between.
Who submits shipping instructions?
The party that booked with the carrier, usually the shipper or its forwarder, through the carrier's portal, an EDI message or the carrier's template.
