Export Packing Is Priced to the Cargo and the Voyage.
There is no flat per-machine rate because two machines of the same weight can need very different packs: one robust fabrication ships in a braced open crate, while a precision machine of identical mass needs a closed case, a sealed moisture barrier and a calculated desiccant charge. So a real quote is built up from the case structure, the volume of timber, the corrosion and moisture protection, the ISPM-15 treatment and the handling and documentation — priced to what the cargo and the route actually require.
As a rough industry guide, exporters commonly budget somewhere between one and ten percent of a product's value for protective packing, with robust open-crated cargo at the low end and fragile, fully enclosed and moisture-protected machines at the higher end. Sea freight itself is then charged on whichever is greater of weight or volume (per cubic metre), which is why a well-engineered, tightly-sized case can lower your freight as well as protect the machine. The way to a firm number is simply to send the cargo details below.
