Port Cut-Off Times Explained
Miss a cut-off by one hour and your cargo rolls to the next vessel. Here's every deadline you need to track — and how much buffer to build in.
Types of Port Cut-Off Deadlines
There are five distinct cut-off types. Missing any one of them can roll your cargo.
SI Cut-Off (Shipping Instructions)
Deadline to submit final shipping instructions to the carrier — including consignee details, cargo description, marks & numbers, and BL instructions. Typically 3–5 days before ETD.
VGM Cut-Off (Verified Gross Mass)
SOLAS requires verified container weight before loading. VGM must be submitted to the carrier before this deadline. Usually 1–2 days before gate closing.
Documentation Cut-Off
Deadline for all export documentation: customs clearance, dangerous goods declarations, certificates of origin, etc. Varies widely by port and cargo type.
Gate / CY Closing
Physical deadline for delivering the loaded container to the terminal. After this, the terminal gate literally closes for that vessel. This is the hard deadline.
Early Receiving Date (ERD)
The earliest date the terminal will accept containers. Arrive before ERD and the terminal turns you away. Important for planning trucking.
Typical Cut-Off Windows by Port
Cut-off times vary significantly by port and carrier. These are typical ranges — always confirm with your carrier.
| Port / Region | SI Cut-Off | VGM Cut-Off | Gate Closing |
|---|---|---|---|
| Shanghai / Ningbo | 5 days | 3 days | 24–36 hrs |
| Rotterdam / Hamburg | 3–4 days | 48 hrs | 24 hrs |
| Los Angeles / Long Beach | 4 days | 48 hrs | 24–48 hrs |
| Singapore | 3 days | 24 hrs | 12–24 hrs |
| Jebel Ali (Dubai) | 4 days | 48 hrs | 24 hrs |
How to Prevent Cargo Rolls
Cargo gets rolled when you miss a cut-off. Here's how to build a system that doesn't.
Submit SI at booking, not at cut-off
Don't wait for the SI deadline. Submit preliminary SI when you book and amend later. This gives you buffer for corrections without risking the deadline.
VGM on the day of stuffing
Weigh the container immediately after stuffing and submit VGM the same day. Waiting until the cut-off day means one scale malfunction or system glitch rolls your cargo.
Gate delivery 24 hours before closing
Target terminal delivery at least 24 hours before gate closing. Trucking delays, port congestion, and terminal system outages are all common — build in buffer.
Pre-clear customs before gate opening
Get customs clearance completed before the container arrives at the terminal. Clearing at the gate wastes time and risks missing the closing window.
Track ERD to avoid wasted truck runs
Terminals won't accept containers before the ERD. If your truck arrives early, it gets turned away and you pay repositioning fees plus a wasted trip.
Set internal deadlines 24 hours ahead of carrier deadlines
Your team's deadlines should be one day before the carrier's. This creates an automatic buffer that absorbs delays without panic.
