ONE Line ETA updates from your shipment sheet
Refresh Ocean Network Express Bill of Lading ETAs without rebuilding your tracking board from scratch.
Why ONE Line ETAs go stale
Ocean Network Express is the carrier most likely to be labelled inconsistently in a shipment sheet. The same line shows up as ONE, ONE Line, Ocean Network Express, and ONEY depending on who typed the row, and boards assembled from several forwarders often contain all four spellings in one column. Tools that match carrier names exactly will treat those as different lines and silently skip most of them.
Melsun normalizes all of these to the same carrier before lookup, so a messy shipping line column is not something you have to clean before you can track. The rows resolve regardless of which spelling your forwarder happened to use.
The rest of the workflow matches the other supported carriers. Upload the board you already keep, confirm the detected columns, and get the same workbook back with refreshed dates and movement detail appended beside your existing data.

How it works
- Upload a sheet that includes ONE Bills of Lading.
- Confirm mapped BL and carrier columns.
- Run tracking for refreshed ETAs.
- Export results for your ops channel.
Uploads accept .xlsx, .csv, and .pdf up to 5 MB, with up to 100 rows per run. Legacy .xls workbooks are rejected — save as .xlsx first.

ONE Line Bill of Lading formats
ONE Bills of Lading are usually issued with an ONEY prefix, though the number is often passed around without it. Both forms work, and Melsun reformats the value to whatever the carrier lookup expects.
| Format | Example | Notes |
|---|---|---|
| ONEY prefix | ONEYTYOA12345678 | The standard issued form. Melsun strips or reformats the prefix as required by the lookup. |
| Bare reference | TYOA12345678 | The same booking without its prefix, common in forwarder exports. Accepted as-is. |
| Numeric references | 1234567890 | Numeric-only references are accepted when the shipping line identifies ONE. |
The shipping line column can read ONE, ONE Line, Ocean Network Express, or ONEY. All four normalize to ONE Line, which is why mixed labels across a merged sheet do not cause skipped rows.
What Melsun adds to your sheet
Every tracked ONE Line row comes back with these columns appended to the right of your existing data.
| Column | What it contains |
|---|---|
| Melsun ETA | The refreshed arrival date pulled from the carrier. Reads TRACKING UNAVAILABLE when the lookup could not be completed. |
| Melsun Status | One of Pending, Tracked, Unavailable, Failed, or Unsupported carrier, so you can filter the rows that still need attention. |
| Melsun Milestone | The latest movement recorded for the shipment, such as loaded for export, discharged at transshipment, or discharged at destination. |
| Melsun Milestone Date | The date attached to that milestone. |
| Melsun Location | Where the milestone happened, as reported by the carrier. |
| Melsun Vessel / Laden / Empty | Vessel and voyage where the carrier publishes it, plus laden or empty container state. |
| Last Updated (UTC) | When the row was refreshed, so a shared sheet always carries its own age. |
ONE lookups resolve a full movement history, so milestone, location, and vessel columns are usually populated alongside the refreshed ETA.
Troubleshooting
- My sheet spells the carrier four different ways
- That is fine and does not need fixing. ONE, ONE Line, Ocean Network Express, and ONEY all normalize to the same carrier before lookup, so every variant routes correctly within a single run.
- A ONE row returned TRACKING UNAVAILABLE
- Check whether the value in the Bill of Lading column is actually a booking reference rather than a Bill of Lading, which is a common mix-up on ONE shipments. If the number is correct, retry the failed rows — retries on a completed task do not consume another run.
- The mapping preview picked the wrong column
- The preview exists precisely so you catch that before spending a run. It shows the detected Bill of Lading and shipping line columns with sample rows and a confidence score. If it looks wrong, the usual fix is a clearer header — renaming a column to BL Number or Shipping Line is normally enough for the detection to lock on.
FAQ
- Can Melsun track ONE / Ocean Network Express BLs?
- Yes. Shipment Tracking supports ONE Line alongside Maersk, MSC, and CMA CGM, and recognizes the ONE, ONE Line, Ocean Network Express, and ONEY labels as the same carrier.
- Where do I start?
- Open Shipment Tracking, sign in, and upload your first sheet. Five runs are included free so you can prove the workflow on live Bills of Lading before paying, and pricing details are on the pricing page.
- Do I have to reformat ONEY numbers before uploading?
- No. Melsun handles the prefixed and bare forms and reformats the reference to whatever the carrier lookup expects, so you can upload the column exactly as your forwarder sent it.
- What do I actually get back?
- For Excel and CSV uploads you get your original workbook with seven columns appended: refreshed ETA, status, latest milestone, milestone date, location, vessel and container state, and a Last Updated timestamp. You also get a PDF summary suitable for sharing outside your team.
- Is there a limit on how many sheets I can run?
- The free tier includes five runs. Paid tiers cover thirty runs per month on Starter and two hundred on Pro, and because a run is one executed sheet rather than one row, a single run can cover up to a hundred Bills of Lading.
