When the Selling Point Is Finish, Moisture Is the Enemy.
Italy exports things that are bought for how they look and how precisely they work — a polished die-casting machine, a pallet of glazed porcelain tiles, a roll of fashion leather, a case of fine wine. Every one of those is degraded by humidity in ways the customer sees immediately: a tide-mark on a ceramic surface, a rust freckle on a bright machine bed, mould on a label, a tainted cork. The damage is not structural, it is cosmetic, and for goods sold on appearance that is worse. BENZ treats the drying agent as part of protecting the finish, not just the function.
Geography sharpens the problem. Italian cargo loads in Mediterranean heat and then sails from Genoa, La Spezia or Gioia Tauro into still hotter, wetter trades, so the air sealed into the box already carries a heavy moisture charge that the day-night cycle then drives onto the steel. We size the calcium chloride to that real starting humidity and the route using the DIN 55473 unit method, and where the cargo is a finished surface that cannot tolerate any chemical contact we specify nitrite-free clay instead.
