A truck is weighed on a weighbridge (the 'kanta'): gross weight with the load, tare weight empty, and net weight — the coal — as the difference. The kanta slip records all three.
The net weight at unloading is often different from the net weight at loading. Common reasons include moisture — wet coal dries and loses weight on the way, or gains it in rain; spillage and dust; two weighbridges that don't read exactly alike; and, sometimes, pilferage.
Because some difference is normal, many buyers and sellers agree a tolerance in their terms — a small percentage within which the difference is simply accepted — and who bears a shortage beyond it: the seller, the transporter, or both. That split is a commercial agreement, not a fixed rule.
More detail
Excess weight happens too — most often when coal picks up water in transit. It deserves the same scrutiny as a shortage, because the buyer may be paying for water.
A difference is easiest to settle when the evidence was captured at the time: both kanta slips, the lorry receipt, the vehicle number, and the moisture reading if the coal was tested. Weights entered from memory later are the hardest to defend.
Worked example
Illustration only: a truck leaves with 30.00 t net and arrives showing 29.70 t — a 0.30 t (1%) difference. Whether that is accepted, deducted from the transporter or claimed from the seller depends on the tolerance and terms that were agreed.
Common confusion
A weight difference is not the same as a quality difference. Coal that lost moisture weighs less but may test at a higher GCV as received — check both before deciding what went wrong.
What it means if you trade coal
Agree the tolerance and who bears a shortage before the load moves, write it into the terms, and keep both kanta slips with the trip.
How Coal Boss handles this · In Coal Boss today, with limits
Lifting entries record loading and unloading weight with the shortage; a sales-side shortage report and tolerance settlement are not on screen yet.

Hinglish mein, short mein
Kanta slip mein gross, tare aur net weight hota hai. Unloading ka net weight loading se aksar alag aata hai — zyadatar nami (sookhna ya baarish), maal girna aur dhool, do kante ka thoda alag padhna, kabhi chori. Kai kharidaar-bechne wale ek tolerance tay karte hain aur uske upar shortage kiske khaate jaayegi — ye aapas ka sauda hai, koi fixed niyam nahi. Dono kanta slip aur LR sambhal ke rakhiye — zyadatar jhagde inhi se sulajhte hain.
