Korean Used Car Cut-Off Date: SI, VGM, CY & Doc Closing Times Explained (2026)

A Korean used car cut-off date is the latest moment by which a document or the car itself must reach the shipping line before a vessel will accept it. Every booking has several — the documentation (SI) cut-off, the VGM cut-off, the CY/cargo cut-off, and a customs cut-off — all falling roughly 1–3 days before the vessel's departure (ETD). Miss any single one and your car is rolled to the next sailing, adding 1–3 weeks of delay plus possible storage and re-booking cost.

If you have just received a booking confirmation and you are staring at terms like "Doc cut-off", "VGM cut-off", and "CY cut-off" without knowing which is which, this guide is for you. The cut-off date is the single most common reason a Korean car misses its boat — and it is entirely avoidable once you understand the deadlines. Each cut-off ties back to a document we have covered before: the booking confirmation is where the dates are printed, and the shipping instructions (SI) are what the documentation cut-off is waiting for.

What a Cut-Off Date Means in Korean Car Export

A vessel does not wait. A car carrier or container ship calling at Busan, Incheon, or Pyeongtaek keeps a fixed berth window, and everything that will sail on it must be locked in before that window — both the physical cargo and the data the carrier needs to manifest, weigh, and document it. The deadlines that enforce this are cut-off dates (also called closing times or deadlines).

The key thing first-time buyers miss is that a booking has more than one cut-off, on different days, for different things. Meeting the cargo deadline but not the paperwork deadline still gets your car rolled. Three principles define how cut-offs work:

• They are hard, not soft. A cut-off is a contractual deadline set by the carrier. Lines run hundreds of boxes per sailing and do not hold a ship for one late car — past the cut-off, the answer is simply "next vessel".
• They come in a sequence. The documentation and VGM cut-offs generally fall a little before the physical cargo cut-off, because the carrier needs the data finalised to plan the stow and the manifest before the box is even gated in.
• They are printed on your booking. Every cut-off date and time is stated on the booking confirmation. They are not a secret — they are the schedule you work backward from.

Because Korea exports both by RoRo (mostly Pyeongtaek and Masan) and by container (mostly Busan and Incheon), the exact cut-offs differ by mode — covered in detail below. According to the Korea Customs Service, export shipments must also clear an export declaration before loading, which is its own effective deadline layered on top of the carrier's cut-offs.

The Five Cut-Offs Every Shipment Has

Strip away the jargon and there are five deadlines that govern whether your car makes its vessel. Not all apply to every shipment — a single RoRo car skips the VGM — but a container booking will show most of them.

1. Documentation / SI cut-off

The deadline to submit your shipping instructions — the buyer-authored data the carrier turns into the Bill of Lading. It is frequently the earliest of the cut-offs, because the line needs the manifest data before sailing. Late or messy SI is a leading cause of preventable roll-overs.

2. VGM cut-off

The deadline to file the Verified Gross Mass — the certified total weight of the packed container — under the international SOLAS convention. No VGM, no load: it is a legal requirement, not a carrier preference. This cut-off applies to container shipments, not single-car RoRo.

3. CY / cargo cut-off

The physical deadline: the car (RoRo) or the loaded container (CY = container yard) must be inside the terminal by this time. Also called the gate-in deadline or cargo closing time. This is the one most people picture when they hear "cut-off", but it is only one of several.

4. Customs / export-declaration cut-off

Korean law requires an approved export declaration (수출신고) and the car's de-registration before it can legally leave. While the customs authority sets the rules rather than the carrier, in practice it is a deadline that must be met before the cargo cut-off — a car that has not cleared export cannot be loaded.

5. ERD — earliest receiving date

The opposite bookend. The ERD is the earliest the terminal will take your cargo for a given vessel; the CY cut-off is the latest. Together they form the receiving window. Deliver before the ERD and you are turned away or charged storage; deliver after the cut-off and you are rolled.

Cut-Off Timeline: When Each Deadline Falls Before the Vessel

The cut-offs are not a single date — they are a countdown. While exact timing varies by carrier, port, and lane, the typical sequence out of Korea looks like this, working toward the vessel's estimated time of departure (ETD).

On most weekly services out of Busan or Pyeongtaek, the documentation and VGM cut-offs land a day or two ahead of the cargo (CY) cut-off, which itself sits roughly 1–3 days before ETD. There is no universal number — a feeder service or a routing that goes through a transshipment hub can have an earlier effective deadline, because the car must catch a connecting leg. Korean public holidays (Seollal, Chuseok) pull every cut-off forward, sometimes by days.

This is exactly why the vessel schedule and the cut-offs are read together: the ETD tells you when the ship leaves, and the cut-offs tell you the real deadlines you are working to, which are always earlier than departure.

Why Missing a Cut-Off Causes a Roll-Over

When cargo misses any cut-off, it is rolled over — bumped from the booked vessel to the next available sailing. Understanding why the line does this, rather than just holding a space, is what makes buyers take the deadlines seriously.

A container ship or car carrier is planned as a single, interlocking load. The stow plan, the weight distribution, the manifest filed with customs at the destination, and the berth window are all finalised at the cut-off. After that point, the carrier physically and legally cannot slot in a late car without unpicking the plan for every other box on the ship. So the rule is absolute: in by the cut-off, or on the next vessel.

The most painful part of a roll-over is not the single missed vessel — it is the cascade. Every downstream date moves with it: the arrival, the free-time clock and demurrage risk at the destination, the customs clearance, and the final delivery. A two-day slip at the cut-off can become a three-week slip at the buyer's door. On thin lanes — parts of Central Asia, smaller African ports — the next sailing may be weeks away, which is why our Central Asia export guide stresses building schedule buffer into those routes.

RoRo vs Container: How the Cut-Offs Differ

The two shipping modes Korea uses — RoRo and container — do not share the same set of cut-offs. Knowing which apply to your booking prevents nasty surprises.

The headline difference is the VGM cut-off: it exists for containers (the packed box must be weighed and declared under SOLAS) but not for a single car driven onto a RoRo vessel. RoRo also tends to run more frequently on high-volume lanes such as the GCC, so a missed deadline there may mean a shorter wait than on a less-frequent container service. Either way, the deadlines live on your booking confirmation, and the discipline is identical: hit every cut-off that applies.

What Missing a Cut-Off Actually Costs

A roll-over is rarely a single line-item charge; it is a stack of smaller costs plus lost time. The chart below ranks the typical consequences by how much they hurt a buyer's landed cost and timeline.

For a dealer importing several units, the delay cost dominates: capital is tied up in cars that are not yet sellable, and a buyer waiting at the destination may walk. The downstream risk is subtler — a rolled car arrives later, which can collide with the free-time and demurrage clock at the destination port if clearance is not ready. Build the possibility into your thinking, but treat it as what it is: a cost you should almost never pay, because hitting cut-offs is a process problem, not a luck problem. Fold shipping deadlines into the wider landed-cost plan so a roll-over does not blow your budget.

Buyer Checklist for Cut-Off Dates

You will not personally gate the car into the terminal, but you can confirm your exporter has the cut-offs under control. Six things to verify on every shipment:

1. Get the booking confirmation with all cut-offs stated — documentation/SI, VGM, CY/cargo, and the vessel's ETD, in writing.
2. Identify the earliest cut-off (usually the SI or documentation deadline) and confirm the plan works backward from it, not from sailing day.
3. Confirm the export declaration is filed early, so a customs query cannot eat into the loading window.
4. Ask for a buffer — gate-in a day or two before the CY cut-off, never at the last hour, so a truck or weather delay does not cause a miss.
5. Check the receiving window (ERD to cut-off) so the car is not delivered too early and charged storage, or too late and rolled.
6. Get confirmation each cut-off was met — SI filed, VGM filed, car gated in — before you expect the car to sail.

How SH GLOBAL Manages Cut-Offs

SH GLOBAL Co., Ltd. treats the Korean used car cut-off date set as the backbone of every shipment's schedule — not a deadline to scramble toward. Our standard practice:

• Read every cut-off off the booking. When the booking confirmation arrives, the documentation/SI, VGM, CY/cargo, and customs cut-offs are recorded and the whole plan is built backward from the earliest one.
• File customs early. The export declaration and de-registration are completed well ahead, so a customs query never threatens the loading window.
• Submit SI and VGM before their deadlines. The shipping instructions go in before the documentation cut-off; the VGM is filed during container loading, not at the last minute.
• Gate in with a buffer. The car is delivered inside the receiving window with a day or two of margin before the cargo cut-off — absorbing truck, weather, or holiday delays.
• One coordinated process. Because the documentation, the inspection, and the physical handling run together, a single delay does not cascade into a missed cut-off.
• Confirm and report. Buyers are told each cut-off was met and the car is loaded — so a roll-over is the rare exception, not a recurring surprise.
