Definition & Explanation
Container weighing and the weight declaration are the procedures required under SOLAS Chapter VI Regulation 2, by which the shipper must determine the Verified Gross Mass (VGM) of a packed container and submit it to the shipping line before the vessel's cut-off time. The VGM can be established either by weighing the fully packed container on a certified scale or by adding the individual weights of all cargo items and dunnage to the container tare weight. The obligation was introduced in 2016 following a series of maritime accidents caused by undeclared or inaccurately declared container weights. Shipping lines will not load a container without a valid VGM submission; incorrect declarations can result in fines and liability exposure. The declaration must be signed by a duly authorised representative of the shipper and referenced in the bill of lading or an accompanying document.
