Help and glossary

Written for someone who has never shipped a cargo. Every screen is explained in plain English below, followed by 52 trade terms the screens use. The same text sits behind the “What am I looking at?” strip at the top of each screen.

Screens

Control Tower

/

Import operations, first thing in the morning

The one screen that answers “what needs me today?”. Every cargo we have bought and not yet consumed is on this page: where the ship is, what stage it has reached, and which of them have a problem that costs money if it is left alone. The exception list is ordered by money at risk, not by date, so the top item is always the one worth opening first.

Exposure strip
Rupees currently at stake across all cargoes: demurrage being claimed against us, how much of it we dispute, and how many rebuttal windows close within a fortnight.
Open exceptions
Things the system has spotted by reading the contract against the facts. Each one links straight to the screen where it can be dealt with.
Fleet map
Where each vessel is right now. Cargoes waiting at the Sandheads anchorage are burning laytime.

Parcel register

/parcels

Anyone looking for a specific cargo

The full list of cargoes, sortable and filterable. A parcel is one lot of bulk material under one Bill of Lading — 45,000 tonnes of coke on one ship, not a box in a warehouse. Everything else in the system hangs off a parcel.

Status
Where the cargo has reached in its life: nominated, in transit, at anchorage, discharging, on the road, received at the plant, closed.
B/L quantity
The quantity written on the Bill of Lading at the load port. It is what we pay against provisionally, and the number every later measurement is compared to.

Terms used here: Parcel, Bill of Lading, Laycan, Nomination

Parcel overview

/parcels/:parcelId

Everyone, as the starting point for one cargo

One cargo, end to end. The header names the material, the ship and the Bill of Lading; the timeline shows what has happened; the right-hand rail lists the open problems and the key paperwork. The tabs across the top break the same cargo down by subject.

Fact strip
Commodity, quantity, commercial terms, vessel and Bill of Lading reference — the six things you need before speaking to anyone about this cargo.
Discharge nodes
A deep-draft ship cannot enter Haldia loaded, so the cargo is split: part is lightered into barges at the anchorage, the rest is discharged at berth. Each of those is a node with its own timeline.

Terms used here: Parcel, Lighterage, Mother vessel, Barge, Incoterm

Laytime and demurrage

/parcels/:parcelId/laytime

The laytime analyst

The contract gives us a fixed number of hours to unload the ship, free of charge. Run past it and the shipowner charges demurrage for every day over. This screen recalculates that time from the Statement of Facts, event by event, and puts our number next to the seller's claim. Where the two differ, the reason is a specific event whose treatment we dispute — usually rain or waiting for barges.

Allowed
Cargo quantity divided by the contractual discharge rate. If the contract says 8,000 tonnes a day and the cargo is 45,000 tonnes, we get 135 hours.
Used
Time actually consumed, after excepted periods are stripped out. Sundays, holidays and weather come out if the contract says they do.
Claimed against computed
What the seller says we owe, against what the same events give when the contract is applied strictly. The gap is what a rebuttal is worth.
Rebuttal window
The days left to dispute the claim. Miss it and the claim is deemed accepted in full, whatever the facts say.

Terms used here: Laytime, Notice of Readiness, Turn time, Demurrage, Despatch, Statement of Facts, Laytime statement, Rebuttal window, Weather working day, SHEX

Quantity reconciliation

/parcels/:parcelId/quantity

Operations and commercial

Bulk cargo is weighed several times between the load port and the plant, and it never weighs the same twice. This screen follows the chain — Bill of Lading, draft survey at discharge, weighbridge at the plant — and shows where the material went missing. Each leg is measured in basis points against the tolerance the contract allows for that leg.

Chain
Each measurement in the order it was taken, with the change from the previous one. A leg outside its tolerance is flagged.
Attribution
How much of the shortfall belongs to moisture, to handling losses at the anchorage, and to road transit.
Dry basis
Weight after deducting moisture. If the contract prices on a dry basis, this is the number we pay against, not the wet weight.

Terms used here: Draft survey, Weighbridge, GRN, Dry basis, Basis points, Tolerance

Quality and price adjustment

/parcels/:parcelId/quality

Commercial

The contract specifies what the material should assay at — ash, moisture, fixed carbon and so on. The cargo is sampled at the load port and again at discharge. Where the delivered analysis is worse than the specification, the contract reprices it, and this screen shows that arithmetic step by step. If a parameter is beyond the rejection limit, we have the contractual right to refuse the cargo.

Contract against delivered
Each parameter as promised and as it actually landed. Figures are shown as percentages; internally they are held in basis points so nothing rounds away.
Adjustment working
Penalty per tonne for each step beyond the threshold, multiplied by the priced quantity. This is what we deduct from the final invoice.
Rejection limit
The point past which the cargo may be refused outright rather than merely repriced.

Terms used here: Assay, Price adjustment, Rejection limit, Dry basis, Basis points

Import operations

An import moves on paper. This checklist groups every document by the stage it belongs to and shows what has arrived, what is still expected and who owes it to us. A missing document marked as blocking clearance is the one to chase first: without it, customs will not release the cargo and the plot rent keeps running.

Status
Expected means not due yet. Received means it has arrived. Verified means someone has checked it. Missing means it is late.
Blocks clearance
Customs will not grant out-of-charge without this document, so the cargo cannot leave the port.
Document extraction
Uploading a scan reads the fields off it and offers them for review, each with a confidence score. Nothing is saved until it is confirmed.

Terms used here: Bill of Lading, Statement of Facts, Bill of Entry, Out of charge, Plot rent

Import operations and the customs broker

The Bill of Entry is the import declaration filed with Indian Customs. It must be filed before the ship arrives, or a late fee applies. Once assessed, duty is paid and customs grants out-of-charge, at which point the cargo may leave the port. This screen shows the filing position and the duty calculation in the order the law applies it.

Filing deadline
Counted against the vessel's arrival. An unfiled entry inside the window is shown as a countdown.
Duty cascade
Basic Customs Duty is charged on the assessable value; the Social Welfare Surcharge is charged on the duty; IGST is charged on all three added together.
IGST marked recoverable
IGST is reclaimed as input tax credit, so it is cash flow rather than cost. It is deliberately excluded from the landed cost figure.

Terms used here: Bill of Entry, Basic Customs Duty, Social Welfare Surcharge, IGST, Out of charge, Customs House Agent, Assessable value

Plant materials and operations

From the port the cargo travels to the plant by truck, a few tonnes at a time. Each trip is weighed out at the port and in again at the plant weighbridge, and the difference is the shortage on that truck. Shortages above thirty basis points are flagged: at that level it is no longer spillage, it is worth asking about.

Dispatch, gross, tare, net
Weight loaded at the port; the loaded truck at the plant; the empty truck; and the cargo weight, which is gross minus tare.
Shortage in basis points
The loss on that trip as a share of what left the port. Thirty basis points is 0.30 %.
E-way bill validity
The tax document that lets the truck move. If it expires in transit the truck must stop.

Terms used here: Weighbridge, E-way bill, GRN, Basis points, Transit loss

Commercial and finance

What one tonne of this material actually cost by the time it was standing in the plant yard. The waterfall builds it up from the price we paid the seller, through freight, port handling, duty, demurrage and road transport. It is compared against what was budgeted, and the difference is explained line by line. Quantity shortfall comes first in that explanation because it changes the denominator every other line is divided by.

Per tonne, estimated and actual
Total cost divided by the quantity that actually arrived at the plant, not by what was shipped.
Variance
Actual against budget, in rupees per tonne and as a percentage. Positive means it cost more than planned.
Recoverable
IGST. Paid in cash but reclaimed, so it is shown separately and kept out of the cost per tonne.
Memo
The value of material lost in transit. It is not an extra invoice; it is already reflected in the fact that fewer tonnes carry the same spend.

Terms used here: Landed cost, Variance, IGST, Transit loss, Estimated against actual

Bulk cargo is paid for twice. A provisional invoice goes out on the Bill of Lading quantity as soon as the cargo is loaded, usually against a letter of credit; a final invoice trues it up once the discharge survey and the assay are agreed. Because the invoices are in dollars and we pay in rupees, the exchange rate on the day of remittance differs from the rate on the Bill of Lading date, and that difference is a real cost.

Provisional against final
The first payment, the true-up, and the quality adjustment applied inside the final invoice.
Exchange difference
What the remittances cost in rupees against what they would have cost at the Bill of Lading rate.
Letter of credit
The bank's undertaking to pay the seller once the shipping documents are presented and found in order.

Terms used here: Provisional invoice, Final invoice, Letter of credit, Exchange difference, Price adjustment

Demurrage desk

/demurrage

The laytime analyst

Every open laytime claim in one queue, ordered by how soon the window to dispute it closes. Each row shows what the seller wants, what our own calculation gives, and the days remaining. A claim left past its window is deemed accepted in full, so this is the screen where silence is expensive.

Days remaining
Days left in the contractual rebuttal window, counted from the day the statement was received.
Gap
Claimed less our computed position. This is the amount a successful rebuttal saves.

Terms used here: Laytime statement, Rebuttal window, Demurrage, Statement of Facts

Landed cost across the portfolio

/cost

Commercial and procurement

The same cost analysis, but across every cargo costed in the past twelve months, grouped by supplier, by commodity or by route. It answers which supplier is quietly costing more than the price list suggests, and whether a route is worth its freight advantage once lighterage and port handling are counted.

Variance per tonne
Weighted by quantity received, so a large cargo moves the number more than a small one.
Month costed
A cargo is counted in the month the vessel arrived at the discharge port, or its Bill of Lading month if it has not arrived.

Terms used here: Landed cost, Variance, Incoterm

Inbound to plant

/inbound

Plant materials manager at Jamuria

What is arriving at the plant gate, grouped by day, with today first. It is the receiving desk's view: which trucks are due, how much material they carry, and which of them came in short at the weighbridge.

Today's receipts
Trucks weighed in today, and the tonnage they brought.
Shortage
Weighbridge net against the weight dispatched from the port, for each truck.

Terms used here: Weighbridge, GRN, Transit loss

Contracts

/contracts

Commercial

Each purchase contract in full: what we agreed to buy, at what price and quality, how laytime is counted, and how it is paid for. The risk panel at the top reads the clauses on their own terms and flags the ones that can cost money if the voyage goes badly — uncapped demurrage above all.

Quantity tolerance
The band either side of the contract quantity that the seller may ship at their option, shown as an actual tonnage range.
Laytime terms
The discharge rate, what counts as laytime, and the daily demurrage rate. These are the inputs to every laytime calculation on that contract's cargoes.
Risk flags
Clauses read straight from the contract. Nothing here depends on how any particular shipment went.

Terms used here: Incoterm, CFR, Laycan, Demurrage cap, Charter party, Rejection limit, Letter of credit

Counterparties

/counterparties

Commercial and procurement

Everyone we deal with on an import. Sellers carry a performance record built from their own cargoes: whether they nominated a ship on time, how the delivered quality compared with what they promised, how much demurrage they claimed and how much was ever settled, and how much material went missing between the Bill of Lading and our weighbridge.

Nominated on time
Share of cargoes where the vessel was nominated within the first five days of the laycan window. A late nomination compresses everything downstream.
Quantity loss
Bill of Lading quantity against what reached the plant, across every measured cargo from that seller.
Average delivered quality
Mean of the certificates used for pricing, against what the contract called typical.

Terms used here: Nomination, Laycan, Assay, Demurrage, Draft survey

Executive summary

/executive

The CFO, in ninety seconds

Four numbers and a list. What we spent on imported material in the past twelve months, how far the landed cost ran over budget, what demurrage was claimed and how much of it was recovered, and how much material was paid for but never arrived. Below that, the three live exposures worth the most money today, each one a click from the screen where it can be dealt with.

Import value
Goods value of every costed cargo in the window, in rupees.
Landed cost against plan
Total actual cost against total budgeted cost. Positive means the material cost more than planned.
Quantity lost in transit
Tonnes paid for on the Bill of Lading that never reached the plant, and what that material was worth.
Cost per tonne trend
Twelve months of landed cost per tonne, one line per commodity, plotted against the month the vessel arrived.

Terms used here: Landed cost, Demurrage, Transit loss, Variance

A
Assay
Laboratory analysis of the cargo — ash, moisture, fixed carbon, manganese content and so on — which decides whether the price is adjusted.
Assessable value
The value customs uses to charge duty: the goods value plus freight and insurance to the Indian port.
B
Barge
The smaller craft that receives lightered cargo and carries it up-river to the berth. Also called a daughter vessel.
Basic Customs Duty
The first duty in the cascade, charged as a percentage of the assessable value.
Basis points
Hundredths of a percent. Thirty basis points is 0.30 %. Percentages are held this way throughout so that nothing is lost to rounding.
Bill of Entry
The import declaration filed with Indian Customs. It must be filed before the vessel arrives or a late fee applies.
Bill of Lading
The shipping document issued at the load port. It is the title to the goods, and its stated quantity is what the provisional invoice is raised against.
C
CFR
Cost and Freight. The seller arranges and pays the ocean freight; risk passes to us at the load port; we place the marine insurance.
Charter party
The contract between the shipowner and whoever chartered the vessel. Under CFR and CIF the seller charters, and we usually never see it.
CIF
As CFR, except that the seller also provides the marine insurance.
Customs House Agent
The licensed broker who files the Bill of Entry and shepherds the cargo through clearance.
D
Dead freight
Freight paid on booked space that was never filled, when a vessel cannot load to capacity.
Demurrage
Compensation payable to the shipowner when discharge takes longer than the laytime allowed. Charged at a daily rate, pro rata to the hour.
Demurrage cap
A ceiling on the daily demurrage rate. Where there is none, a long weather delay has no upper bound.
Despatch
The reverse of demurrage: money earned back when discharge finishes early. Conventionally half the demurrage rate.
Draft survey
Working out how much cargo was moved by reading how deep the ship sits in the water before and after. It is the commercial quantity basis for bulk.
Dry basis
Weight or analysis after deducting moisture. Bulk contracts are frequently priced on a dry basis, so moisture is not paid for as if it were material.
E
E-way bill
The tax document that permits a truck to move goods by road. It has a validity period; if it lapses in transit, the truck must stop.
Estimated against actual
The budget booked when the cargo was bought, against the invoices that eventually arrived. The difference is the variance.
Exchange difference
The rupee cost of paying a dollar invoice at the rate on the day of remittance rather than the rate on the Bill of Lading date.
F
Final invoice
The true-up once the discharge survey and the discharge analysis are agreed, carrying any quality adjustment.
Floating crane
A crane mounted on a barge, used to move cargo from ship to barge at the anchorage.
FOB
Free On Board. We charter the ship and pay the freight ourselves from the load port.
G
GRN
Goods Receipt Note. The plant's record that material was received, raised against the weighbridge net weight.
I
IGST
Integrated Goods and Services Tax, charged on the assessable value plus the duty and the surcharge. It is reclaimed as input tax credit, so it is cash flow and not a cost of the material.
Incoterm
The three-letter code that says who arranges and pays for carriage and insurance, and where risk passes from seller to buyer.
L
Landed cost
Everything one tonne cost by the time it stood in the plant yard: the goods, freight, lighterage, port handling, duty, demurrage and road transport, divided by the tonnes actually received.
Laycan
The window during which the vessel must present at the load port. Laydays at one end, cancelling date at the other; present after it and the buyer may walk away.
Laytime
The time the contract allows for discharge, free of extra charge. Expressed as a discharge rate in tonnes per day and converted into hours for a given cargo.
Laytime statement
The seller's or owner's calculation of the demurrage they say is owed, sent after discharge. Our job is to check it against the Statement of Facts and the contract.
Letter of credit
The bank's undertaking to pay the seller once the shipping documents are presented and found to comply.
Lighterage
Transferring cargo from a deep-draft mother vessel into barges at anchorage, so it can reach a draft-restricted port such as Haldia. Also called transloading.
M
Mother vessel
The ocean-going ship that carries the parcel from the load port.
N
Nomination
The seller naming the ship that will carry the cargo, and the buyer accepting it. A late nomination compresses every deadline downstream.
Notice of Readiness
The master's declaration that the ship is ready to work cargo. It starts the laytime clock, subject to turn time. Whether it can be tendered before berthing depends on the contract.
O
Out of charge
Customs' final release. Until it is granted the cargo cannot leave the port, and plot rent keeps running.
P
Parcel
One lot of bulk cargo under a single Bill of Lading — for example 45,000 tonnes of metallurgical coke on one ship. It is the central noun of this system. It is never a package or a box.
Plot rent
What the port charges for open storage of cargo on its land, by area and by day. Free days first, then the meter runs.
Price adjustment
A penalty or bonus applied per tonne when the delivered analysis differs from the contract specification.
Provisional invoice
The seller's first invoice, raised on the Bill of Lading quantity, usually for ninety percent of the value.
R
Rebuttal window
The days the contract allows to dispute a laytime statement. Let it pass and the claim is deemed accepted in full.
Rejection limit
The point beyond which off-specification cargo may be refused outright rather than merely repriced.
S
Sandheads
The deep-water anchorage in the approaches to Haldia where lighterage is carried out.
SHEX
Sundays and Holidays Excepted — they do not consume laytime. SHINC is the opposite: they count.
Social Welfare Surcharge
A surcharge of ten percent, charged on the Basic Customs Duty rather than on the goods.
Statement of Facts
The port agent's chronological log of everything the ship did: arrival, notice, hatches open, stoppages, completion. It is the evidence a laytime calculation is built from.
T
Tolerance
The variation a contract accepts before a difference becomes a claim — on quantity between two measurements, or on the shipped quantity against the contract.
Transit loss
Material that left the port on a truck and did not arrive at the plant. It is not an invoice; it shows up as fewer tonnes carrying the same spend.
Turn time
A grace period between the Notice of Readiness and laytime starting — typically six or twelve hours.
V
Variance
Actual less estimated. Positive means it cost more than planned, and is shown in magenta throughout.
W
Weather working day
A day on which the weather permits cargo work. Time lost to rain does not count as laytime if the contract is on weather working days.
Weighbridge
The truck scale at the plant. Gross weight of the loaded truck, less the tare weight of the empty truck, gives the net cargo received.
