Export Crating Guide

Export crating vs domestic crate

A domestic crate is often optimised for short road hauls, known forklift practice and a familiar plant-to-plant route. An export crate must survive a longer chain: yard storage, multipoint handling, crane lifts, container or break-bulk stowage, ship motion, stacking and lashing forces, salt-laden air, multi-week temperature cycling, destination inspection and unknown storage dwell after arrival. That is why copying a domestic open frame onto an ocean booking is a common and expensive failure.

If the cargo is capital equipment, treat export crating as a written specification, not a purchase of “strong looking wood.” Definition of the wider term: what is seaworthy packaging.

Export crate design factors: weight, CG, lift, stacking, voyage

Industrial export crating is structural design under logistics loads. Guessing timber size from habit produces tip risk, base failure, crushed sheathing or unusable lift geometry. Capture the inputs below before members are cut.

For over-dimensional units, the same factors still apply, but walls may become skid-and-frame or break-bulk weather covers rather than a six-sided box. See over dimensional cargo packing.

ISPM-15 and heat treated export crates

ISPM-15 is the international standard for solid wood packaging material (WPM) in international trade. It requires approved treatment (commonly heat treatment) and official IPPC marks so inspectors can verify reduced pest risk. Buyers searching for heat treated export crates or ISPM-15 export crates are usually asking for this compliance layer, not for a guarantee of corrosion safety.

Construction principles, marking and documentation

Construction principles

Marking

Clear marks reduce mishandling more cheaply than extra timber. At minimum plan for: shipper and consignee identifiers, package number, gross and net weight, dimensions, centre of gravity mark, lift points or “lift here,” “this way up,” fragile or do-not-stack where true, and IPPC marks on solid wood WPM. Marks must remain legible after rain and abrasion; stencil quality is part of seaworthy practice, not decoration.

Documentation

Pair the physical pack with a packing list that matches contents, weights and package count; timber or treatment certificates when required; photos of critical steps when the buyer specifies them; and any packing instruction reference number used in the commercial documents. Incomplete paper can hold cargo even when the timber is sound.

Export crating cost drivers

There is no honest single price for export crating. Cost follows cargo volume (CBM), mass, structure type, interior materials, route weeks, on-site labour and documentation scope. Comparing quotes without the same scope is how “cheap crates” win RFQs and lose machines at discharge.

Deep cost authority (no fake rate cards): machinery export packing cost.

Blocking, bracing and load path for machinery export crates

Export crates fail less often from “not enough timber” and more often from wrong load path: forces never reach the members designed to carry them. Blocking and bracing convert machine mass and voyage acceleration into controlled reactions at skid, walls and lift hardware.

Blocking is part of seaworthy structure, not decoration. Pair it with the interior climate stack: VCI, barrier free volume and desiccant. Timber alone does not make an ocean pack complete. System map: seaworthy packaging system.

RFQ checklist for export crating

Send engineering data, not only “quote for export crate.” Incomplete RFQs default to habit timber and missing climate layers.

Ask for an itemised system quote: structure type, ISPM-15 timber, VCI, barrier, desiccant quantity basis, labour location, marks and documents. A single line “crate supply” is not comparable across vendors.
