Gross, Tare, and Net Weight at a Scrap Yard

The three weights on a scale ticket

Gross weight is the loaded vehicle weight. Tare weight is the empty vehicle weight. Net weight is the material weight calculated by subtracting tare from gross.

For example, if a loaded vehicle weighs 7,240 lb and the empty vehicle weighs 5,980 lb, the calculated net load is 1,260 lb. The yard may then separate that load into more than one payable material or grade.

Why tare weight can change

Fuel level, passengers, tools, trailers, snow, mud, water, and items left in the vehicle can change an empty weight. Follow the yard's instructions about who and what should remain in the vehicle during each weighing.

When possible, use the same vehicle and trailer configuration for the loaded and empty weights. Never rely on an old tare weight unless the yard accepts it for the current transaction.

A useful ticket check

Before leaving, confirm that the ticket identifies the date, yard, gross weight, tare weight, net weight, units, material grades, price basis, and final payment clearly enough for your records.

• Check whether the ticket uses pounds, kilograms, short tons, metric tonnes, or another unit.
• Ask which weight applies to each grade when one trip contains mixed material.
• Save a photo or digital copy in case the paper ticket fades.

Use net material weight in an estimate

A payout estimate should use the material weight, not the loaded vehicle weight. In ScrapValue, enter the best net weight available for each material and pair it with the yard's matching grade and quote.
