Method 1 weighs the whole packed container on certified equipment. Method 2 (this calculator) sums cargo, packing materials and the tare printed on the container's door — permitted where the shipper is certified.
Stenciled on the container door under TARE. The presets above are typical values; always use the actual door figure for your unit.
