What should an export wooden box and crate manufacturer provide for machinery?
A custom case or skid engineered to mass, centre of gravity and lift method on ISPM-15 solid wood packaging material, plus an interior protection plan for VCI, barrier and desiccant so the timber is part of a complete seaworthy system rather than an empty container.
What is the difference between an export wooden box and an open crate?
A closed box or case is fully sheathed and better for weather, LCL handling and sensitive surfaces. An open crate is a braced frame that saves mass and cost for robust cargo but exposes the load more to weather and handling contact. Choose with route and cargo sensitivity in mind; see the crate vs box guide.
Do export machinery cases need ISPM-15 timber?
If solid wood packaging material is used in international trade, it must be treated and marked under ISPM-15 rules. Non-compliant solid wood risks delay, treatment or rejection at destination. Repair wood and dunnage must follow the same control.
What data do I need to request a custom export crate quote?
Shipping mass, centre of gravity, outline dimensions with protrusions, lift method, shipping mode, voyage weeks and climate, packing location, and metal or oil-free requirements. Incomplete data produces incomplete structural and moisture design.
Can a wooden case alone make a shipment seaworthy?
No. Seaworthy packaging is a system: structure, corrosion control, moisture barrier, desiccant, restraint, marking and documentation. A strong case with wet metal or no moisture control still fails at sea.
How do VCI, barrier bags and desiccant fit inside an export crate?
VCI protects metal surfaces, the barrier creates a sealed free volume, and desiccant sizes to that volume and route climate. The case design must allow correct seal sequence and protect the barrier from puncture by timber edges and fasteners.
What do ASTM D6251 and ASTM D6039 mean on a buyer RFQ?
They are common commercial references for wood shipping box and crate construction language. Use them to clarify style intent, then engineer the real case to cargo mass, CG and voyage. Do not treat the document name alone as proof of voyage fitness.
When should I use a load-rated skid instead of a closed case?
When mass and lift geometry dominate, when weather protection is handled by covers or mode design, or when the unit is too large for practical closed sheathing. The base still needs engineered members, CG control and marks.
How is ordering and packing sequenced for a custom export case?
Submit RFQ data, agree format, complete structural and interior design, manufacture ISPM-15 timber, then pack with clean dry cargo, immobilisation, VCI, barrier, desiccant, marks and documents. Full service teams can own the sequence end to end.
How is a system manufacturer different from a pure wood box shop?
A pure wood shop focuses on timber fabrication. A system manufacturer also specifies and supplies corrosion and moisture materials, writes one packing instruction across layers, and remains accountable for how the case and interior work together. Process discipline still determines field results.
