ERD vs CY Cut: Two Deadlines on Different Rhythms
DIRECT ANSWER
ERD opens the cargo receiving window; CY Cut closes it. ERD is the first day a loaded container can be delivered to the terminal. CY Cut is the deadline before vessel sailing. The two are set by different parties on different rhythms. Operators who treat them as one signal miss the changes happening to the other.
What is the difference between ERD and CY Cut, side by side?
- RoleERD opens the receiving window. CY Cut closes it.
- Set byERD: terminal + vessel operator. CY Cut: carrier (terminal enforces).
- What governs itERD: yard capacity, berthing, labor. CY Cut: vessel manifest closure, sailing time.
- How it movesERD: forward or backward. CY Cut: almost always pulls in (earlier).
- If you miss itBefore ERD: truck refused at gate, returned to yard. After CY Cut: container rolled to next vessel.
A real-world example
SAME VESSEL, BOTH DATES MOVE INDEPENDENTLY
An exporter's booking confirmation lists ERD as Monday morning and CY Cut as Friday at 5:00 PM. By Wednesday, the carrier has pulled CY Cut in to Friday at noon because of vessel sailing time. ERD remains Monday. By Thursday, the terminal has shifted ERD forward to Sunday afternoon because of berthing changes. CY Cut remains Friday at noon.
The window the exporter planned against (Monday-to-Friday-5PM) and the window the truck actually has (Sunday-PM-to-Friday-noon) are different windows shaped by different forces. ERD and CY Cut moved on independent rhythms, and the operator who tracked only one missed the change in the other.
How do ERD and CY Cut break operationally when treated as one signal, by role?
EXPORTER
Tracking ERD without tracking CY Cut
Production is sequenced against ERD. Dispatch is sequenced against CY Cut. Operators who watch only the opening of the window get caught when the closing pulls in.
FREIGHT FORWARDER
Communicating one date when both matter
Customers ask "when can I deliver?" and the forwarder answers with ERD. The customer plans against the opening and is surprised when the closing limits the same plan.
DRAYAGE OPERATOR
Two clocks set on different rhythms
The T-3 appointment book is keyed to CY Cut. The T-1 dispatch decision is keyed to ERD. When the two move differently, the appointment and the dispatch can become decoupled.
ERD and CY Cut are different deadlines on different rhythms. Plans that treat them as one signal tend to fail.
What does the data show about ERD vs CY Cut revisions?
OBSERVED ACROSS U.S. EXPORT VESSEL SCHEDULES
Based on aggregated shipment observations across major U.S. ports:
- ERD revisions and CY Cut revisions occur on different rhythms; the two often move independently.
- CY Cut revisions are most often compressions (earlier); ERD revisions can move either direction.
- For a given vessel, both ERD and CY Cut can revise multiple times before sailing.
- Operators who track only one of the two miss meaningful changes to the other.
The two dates are not symmetric. They behave differently and need to be tracked separately, then reconciled into the executable window.

IN SIMPLE TERMS
ERD is the start of the cargo receiving window. CY Cut is the end. Both can change before vessel sailing, and they do not change on the same rhythm. ERD reflects terminal and vessel-side reality; CY Cut reflects carrier and manifest-side reality.
How do ERD and CY Cut move differently before sailing?
Caption: ERD moves on a terminal rhythm. CY Cut moves on a carrier rhythm. They are not the same signal.
What do operators do differently with ERD and CY Cut?
- 01Track ERD and CY Cut as separate signals. They are governed by different parties and move on different rhythms. Watching one is not the same as watching the other.
- 02Reconcile both into the executable window. The operationally meaningful unit is the receiving window, not either date alone. Both bounds need to be re-checked before dispatch.
- 03Use the terminal portal for ERD, the carrier portal for CY Cut. Each source is closer to the rhythm of its respective date. Cross-checking still matters; the gate reconciles both at the moment of truth.
- 04Communicate both dates to internal stakeholders. Production cycles key off ERD; dispatch and document teams key off CY Cut. A single-date communication leaves one team flying blind.
- 05Track stability of both dates by carrier-port pair. Some pairs publish stable ERDs but volatile CY Cuts, or the reverse. Patterns by pair are operationally useful.
Frequently asked questions
What is the main difference between ERD and CY Cut?
ERD is when the terminal will start accepting a loaded container for a specific vessel. CY Cut is when it will stop. ERD opens the window; CY Cut closes it.
Are ERD and CY Cut set by the same party?
No. ERD is set by the terminal in coordination with the vessel operator, based on yard capacity and berthing. CY Cut is set by the carrier in coordination with vessel sailing time. The terminal enforces both at the gate.
Can ERD be later than CY Cut?
No. ERD must always come before CY Cut for the same vessel. The receiving window between them is the only period in which delivery is possible. If revisions cause ERD to approach CY Cut, the window compresses but does not invert.
Which one moves more often?
Both can move multiple times before sailing. CY Cut more reliably moves in one direction (earlier). ERD can move either way. The frequency varies by carrier-port pair.
If I miss ERD, do I miss the vessel?
No. Missing ERD means the truck arrives before the terminal will accept the container, so it is turned away. You can still deliver after ERD, as long as you meet CY Cut.
If I miss CY Cut, what happens?
The container is rolled to the next available vessel, often 7 to 14 days later. Storage, demurrage, detention, and rebooking costs land on the shipper.
Why do ERD and CY Cut blur into one deadline?
Both are dates on the same booking, both relate to terminal acceptance, and both can be communicated as "the cut." Inside a busy operation, the two dates can blur into a single mental "deadline" even though they are operationally distinct.
Track both dates and the window between them.
TradeLanes is the system that determines whether a plan will hold before execution. Each booking is evaluated against the executable receiving window, not the published one, before the dispatch decision is made.
