Industrial export packing for ocean freight

What industrial export packing actually is

Industrial export packing is the engineered combination of structure, climate control, corrosion control, securing and documentation that moves machinery, fabrications and metal kits through plant handling, road or rail, port dwell and multi-week ocean climate. Domestic warehouse packing is not enough. Open poly is not a vapour system. An ISPM-15 stamp alone does not dry the air inside a free volume or protect multimetal surfaces.

There is no single universal product standard named “seaworthy packaging.” What exists is a set of measurable controls: wood packaging treated and marked under ISPM-15 where solid wood is used; free volume closed with multimetal VCI materials after dry clean; moisture load managed with barrier free volume and desiccant sized in recognised unit culture; loads immobilised for ship motion; packages marked for handling; and a packing list that matches kit identity.

Export packing sequence that survives audit

1. Survey. Mass, centre of gravity, metal list, plating, cavities, ESD rules, residual fluids, hold days at origin, terminal dwell expectation, ocean weeks, destination storage.

2. Clean gate. No free water, no process residue at seal. Cold metal entering warm halls must dry fully before bag close. Dirty seal under any film traps corrosion chemistry.

3. Free volume. Close multimetal VCI film or paper free volume on critical bare faces. Use emitters or interleave where wrap cannot reach cavities. Stretch film unitises; it does not replace sealed free volume on bare metal.

4. Ocean humidity design. When sealed life includes multi-week ocean humidity, add aluminium barrier free volume and sized desiccant with VCI. Count plant + warehouse + terminal + ocean + destination days in sealed life.

5. Structure. Skid, open crate or closed case engineered to mass and handling. Solid wood elements treated and marked under ISPM-15 where the destination enforces the standard. Immobilise the unit so free volume does not tear in motion.

6. Marks and documents. Handling symbols, mass, orientation, kit IDs, packing list, method note, certificates and SDS as required by the RFQ. Photo record for high-value units.

What a technical RFQ should put in writing

Metal list and plating. Mass and lift method. Origin hold days. Terminal dwell assumption. Ocean weeks. Destination storage. Whether ESD rules apply. Cavity access. Solid wood packaging requirements for destination. Required documents: SDS, organisational ISO certificates, grade documentation where applicable, method note covering clean gate, free volume, seal, desiccant units and dwell stages.

Grade-tied flexible VCI performance families and vapour-inhibiting ability test culture should be requested where the grade claims them. Organisational ISO 9001 and ISO 14001 certificates prove system management, not that a specific film grade meets a military performance family. Keep those layers separate in the RFQ.
