Sinokor
Container Tracking
Sinokor opened the first Korea–China container service in 1989 and still concentrates on that corridor. Enter a container, bill of lading or booking number for the latest carrier and terminal milestones.
What a Sinokor tracking number looks like
The lookup above accepts any of these in the same field. If one returns nothing, try another. Carriers release milestone data against different identifiers at different stages.

Bill of lading number

Sinokor container prefixes
These owner codes are registered to Sinokor Merchant Marine Co., Ltd. in the BIC ISO 6346 register. Containers moving under a Sinokor booking may also carry a leasing company's prefix. A leased box is still your shipment, the prefix just does not identify the carrier.
How to track a Sinokor shipment
- 1
Find your container or BL number
It is printed on your bill of lading, your booking confirmation, or on the container door itself. Any of the three works in the search box above.
- 2
Sinokor is already selected
Because you are on the Sinokor page, the carrier dropdown is filled in for you. If you actually need a different line, change it. The selection is not locked.
- 3
Enter the number and press Track
Type it exactly as printed. Spaces and dashes are fine, but a mistyped letter will return nothing, since the check digit at the end only validates against the correct serial.
- 4
Read the milestone timeline
You will see terminal and vessel events from origin gate-in through to empty return, plus the vessel and voyage your box is actually on.
You can also check Sinokor's own portal directly at Sinokor cargo tracking . The advantage of tracking here is keeping several carriers on one screen instead of one portal per line.
About Sinokor
Sinokor Merchant Marine launched the first container liner service between Korea and China in 1989, at a point when the two countries had not yet established formal diplomatic relations. That first-mover position on the corridor has defined the company ever since. It remains primarily a Korea–China operator, with Korea–Japan, Southeast Asian and Russian Far East services alongside.
The company reorganised into its current legal form in 1999, which is why you will see both 1989 and 1999 quoted as founding dates. It runs a comparatively large number of small and mid-sized ships suited to short, high-frequency regional rotations rather than deep-sea rotations.
Sinokor publishes very little about itself, and this is a case where the absence is worth stating plainly: third-party fleet estimates vary by nearly ten percent in vessel count and by more than ten percent in capacity. Rather than pick a number from that range, this page omits the figure.
Sinokor tracking: what to check first
SNKU is not a real prefix. It is not registered to anyone in the BIC owner-code register, despite turning up on aggregator lists for Sinokor. The three genuine codes are SKLU, SKHU and SKRU. If your paperwork appears to show SNKU, re-read it.
Sinokor is probably one leg, not the whole journey. As an intra-Asia operator, Sinokor typically carries cargo between Asian ports and hands off to a deep-sea line for anything beyond. If your shipment is bound for Pakistan, the Sinokor portion likely ends at a transshipment hub and the onward leg is reported by a different carrier’s system.
The e-business portal is a separate domain. Sinokor’s corporate site and its customer tracking portal sit on different hosts, and the tracking system takes a language parameter in the URL. Documentation of different vintages points at different addresses.
No published B/L format. Nothing official documents one. Enter exactly what is printed rather than trying to match a pattern from a tracking blog.
What each Sinokor tracking status means
Ocean carriers share the same terminal and vessel event vocabulary, so these milestones read the same whichever line you are tracking.
Gate in
The container passed through the terminal gate at the origin port and is now in the terminal's custody, waiting to be loaded.
Loaded on vessel
The box was lifted onto the ship. This is the milestone that fixes your shipment to a specific vessel and voyage number.
Vessel departure
The ship has sailed from the origin port. Transit time is measured from here, and it is the point most ETA calculations are anchored to.
Transshipment
The container was discharged at an intermediate hub and will be reloaded onto a second vessel. Most delays originate here rather than at origin.
Discharged
The container came off the ship at the destination port. Free time and demurrage clocks typically start from this event.
Gate out
The container left the terminal on a truck or rail wagon. Once this fires, the terminal's storage charges stop and the haulier's clock starts.
Empty return
The unpacked container was returned to the carrier's nominated depot. This closes the shipment and stops any per-diem detention charges.
Where Sinokor shipments usually move
Sinokor tracking questions
Which container prefixes does Sinokor use?
expand_more
SKLU, SKHU and SKRU, all registered to Sinokor Merchant Marine Co., Ltd. in Seoul. Containers leased from the major leasing companies also move on Sinokor bookings under their own prefixes.
Is SNKU a Sinokor prefix?
expand_more
No. SNKU is not registered in the BIC container owner-code register at all. It appears on aggregator lists because it looks like a plausible abbreviation, but it is not a valid container prefix and will never resolve.
When was Sinokor founded?
expand_more
Two dates get quoted and both are defensible. Sinokor launched the first Korea–China container liner service in 1989, which is the operational founding. The current legal entity dates from 1999. We use 1989 because it is the date the shipping business actually began.
How large is Sinokor's fleet?
expand_more
We do not publish a figure. Sinokor releases nothing itself, and third-party sources give anywhere between 69 and 75 ships and between 125,000 and 141,000 TEU. That spread is too wide to present as a fact, so the field is left out.
What is Sinokor's SCAC code?
expand_more
SKLU is the value appearing consistently across published ocean-carrier SCAC lists. NMFTA's own register is paywalled, so like every SCAC on this site it is well corroborated rather than source-verified.
What routes does Sinokor serve?
expand_more
Primarily the Korea–China corridor it pioneered, plus Korea–Japan, Southeast Asia and the Russian Far East. It is an intra-Asia operator, so a shipment reaching Pakistan would involve Sinokor carrying one regional leg rather than the whole journey.
Does Maalbardaar charge for Sinokor tracking?
expand_more
No. Tracking is included with a free Maalbardaar account, which also lets you keep shipments across several carriers on one dashboard instead of checking each carrier's portal separately.
Every carrier on one dashboard.

Fleet figures omitted: sources give between 69 and 75 ships and between 125,000 and 141,000 TEU, and Sinokor publishes nothing itself.
