USE CASE — IMPORT VISIBILITY
One bill of lading. The whole shipment.
An importer should be able to hand over one reference number and get back everything: the containers, the vessel, the arrival, and the full Indian leg through port and CFS down to the truck that collected it.
Running this by hand today? and we will show you the same thing on your own consignments.

What this costs today
Someone takes the bill of lading and starts looking things up:
- Find the containers. Look up the bill of lading to see which containers are on it and what size they are.
- Find the vessel. Separate lookup for the carrying vessel, where it loaded, whether it transships, and when it is due.
- Find the Indian leg. For each container individually: port in, port out, CFS in, CFS out.
- Find the truck. For each container again: which vehicle collected it.
- Do it all again tomorrow. Nothing is stored as a record, so the next person asking “where is it” starts from the bill of lading.
Two lookups, in two places, repeated for every container, re-done every time somebody asks where it is.
What one reference should return
| Field | Detail |
|---|---|
| Containers | Every container on the bill of lading, with size and type |
| Vessel and routing | Carrying vessel, port of loading, transhipment where it applies |
| Arrival | Estimated arrival into the Indian port |
| Cargo | Description, weight, package count |
| Port movement | Gate-in and gate-out at the port, with timestamps |
| CFS movement | Gate-in and gate-out at the CFS, with timestamps |
| Collection | The vehicle that collected each container |
One shipment record, assembled once, readable by anyone who needs it rather than reconstructed on demand by whoever is free.
When the record is complete
A tracking screen that shows nine fields and hides the three it could not find is worse than useless, because it looks finished. The record is complete when:
- Every container on the bill of lading is accounted for
- Every field is either captured or explicitly marked unavailable
- Anything missing or contradictory is flagged for a person rather than quietly resolved
A blank field and a field that means “this did not happen” look identical. The difference matters when you are deciding whether to send a truck.
Why it matters
The cost is not the lookups. It is that the people who should be acting on status are instead chasing it, and that nobody can answer a customer question or plan an onward move until somebody has done the legwork first.
That delay has a price attached. See detention vs demurrage for why a two-day gap in India costs more than most explanations suggest, and Bill of Entry status for the customs side of the same record.
Questions
How do I track a sea shipment using a bill of lading number?
Conventionally you do it in two places. The carrier or manifest system tells you which containers are on the bill of lading, the vessel carrying them and when it is due. A separate Indian system tells you what happened to each container once it landed — port gate-in and gate-out, CFS gate-in and gate-out, and the collecting vehicle. The second lookup has to be repeated per container.
Can one lookup return every container on a bill of lading?
It should. A bill of lading usually covers several containers, and tracking them one at a time is the step that makes status chasing expensive. The useful output is a single shipment record where every container on the bill is listed with its own movement history.
What is the difference between a master bill of lading and a house bill of lading?
A master bill of lading (MBL) is issued by the carrier to the freight forwarder or NVOCC. A house bill of lading (HBL) is issued by that forwarder to the actual shipper. One master bill commonly sits above several house bills. In an Indian import manifest this shows up as a line number for the master and a sub-line number for each house bill underneath it.
Why does the Indian leg need a separate lookup?
Carrier tracking generally ends at the port of discharge. What happens afterwards — the move into and out of the port, the CFS, and the truck that collected the box — sits in Indian systems rather than with the shipping line. Joining the two halves is the work that normally falls to a person.
What is a CFS and why does it matter for tracking?
A Container Freight Station is where import containers are moved for customs examination and de-stuffing. The time between CFS gate-in and gate-out is where a large share of avoidable delay and detention cost accumulates, which is why the timestamps matter rather than just the current location.
What should happen when data is missing?
It should say so. A tracking record that quietly leaves a field blank is indistinguishable from one where nothing happened. Anything unavailable should be marked unavailable, and anything contradictory should be flagged for a person rather than resolved silently.
One record per shipment
Ahjam Cargo assembles the shipment from the bill of lading and keeps it current — containers, vessel, arrival, and the Indian leg through port and CFS — alongside the customs status, the documents and the charges accruing against it.
