Packaging for Machinery Export from India: Complete Specification Guide 2026

Machinery export packaging is the most demanding category in international freight. A precision-engineered machine that took months to build and costs lakhs of rupees can be destroyed in transit by packaging that was designed without understanding the forces of ocean freight.

This guide is written for machinery manufacturers, engineering companies, and capital equipment exporters in Pune and Maharashtra who export via sea freight to Europe, the Middle East, Southeast Asia, and the Americas.

Why Machinery Packaging Is Different

Consumer goods packaging is designed for one journey of a few days. Machinery packaging must protect equipment that:

Cannot be easily replaced if damaged

May take 25 to 35 days to reach the destination by sea

Weighs hundreds or thousands of kilograms

Has precision machined surfaces, electronic components, and hydraulic systems that can be damaged by moisture, corrosion, or impact

May be handled multiple times -- at the factory, at the ICD, at the port, on the vessel, at the destination port, and at the final site

A machinery packaging failure does not just mean a damaged machine. It means replacement production time, emergency air freight, site installation delay penalties, and a severely damaged customer relationship.

Wooden Export Crate Design for Machinery

The outer container for most machinery export is a custom wooden export crate. Unlike standard-sized boxes, machinery crates are built to the specific dimensions of the machine.

Crate Design Rules

Internal dimensions: Machine dimensions plus 75 to 100mm clearance on each side (left, right, front, back), 100mm at base (for cushioning), and 75mm at top.

Timber specification:

Under 200 kg: 18 to 25mm pine or silver wood.

200 to 500 kg: 25mm pine or silver wood with additional cross-bracing.

500 to 2,000 kg: 32mm hardwood or pine, doubled at corners, with structural cross-bracing.

Above 2,000 kg: Engineering specification required -- consult packaging engineer.

Base: Integrated wooden pallet base with 4-way forklift entry. For machines above 500 kg, the pallet stringers should be 75 x 100mm minimum hardwood.

ISPM-15: All timber used in the crate must be heat-treated and ISPM-15 certified. The crate supplier should provide the ISPM-15 certificate with delivery.

Inner Protection System for Machinery Export

Moisture Barrier

HDPE tarpaulin or aluminium foil sheet lined inside the crate walls before placing the machine. This prevents condensation from reaching the machine surface during the 25 to 35 days of sea transit.

For highly sensitive equipment: vacuum seal the entire machine inside an aluminium foil vacuum bag before placing in the crate.

VCI Corrosion Protection

Any exposed ferrous metal surface on the machine -- machined shafts, guide rails, flanges, castings -- must be coated with VCI (Volatile Corrosion Inhibitor) protection before packaging.

Options:

VCI film: Wrap each exposed metal surface.

VCI paper: Place sheets of VCI-impregnated paper inside the packaging enclosure around the machine.

VCI liquid: Spray-coat exposed metal surfaces for large machines.

VCI protection is essential for sea freight routes above 20 days, particularly to Europe where monsoon-season shipments from India arrive in autumn and winter when condensation risk is highest.

Foam Cushioning

25 to 50mm PE foam sheets on all surfaces between the machine and the crate walls. For machines with protruding components (shafts, nozzles, fittings), custom foam cut-outs are shaped to protect each protrusion without allowing movement.

Desiccant

Silica gel desiccant placed inside the sealed moisture barrier at 2 to 3 units per cubic foot of internal crate volume. This absorbs residual moisture inside the sealed package over the full duration of the voyage.

Container Loading for Heavy Machinery

Weight and Balance

Machinery crates are heavy. A single crate containing a large industrial pump or compressor may weigh 3 to 8 tonnes. Container maximum payload for a 20-foot container is approximately 22 to 24 tonnes. Plan the container load carefully -- a single heavy machine may take 30 to 40 percent of the container payload.

Distribute weight across the container floor. Do not place all heavy equipment on one side of the container -- this creates a list during ocean transit that can cause toppling of lighter cargo in adjacent containers.

Crate Placement

Heavy crates go against the end wall of the container first. Work toward the doors. This ensures the weight presses against the structural wall of the container rather than the doors.

Lashing and Choking

Every wooden crate must be secured to the container floor using:

Timber chock blocks placed against the crate base on all four sides, nailed or bolted to the container floor.

PP strapping or steel lashing bands from the crate to the container floor lashing rings (D-rings) -- minimum two lashing bands per crate.

A machinery crate that is not properly lashed can move during ocean swell. A 2-tonne crate moving even 200mm inside a container generates an impact force that can destroy both the crate and the container wall.

---

Pre-Shipment Inspection and Documentation

Before the container is sealed, the following must be documented:

Photograph of each machine inside the crate with foam and VCI protection visible.

Photograph of each crate showing ISPM-15 mark.

Photograph of loaded container from both ends.

Photograph of lashing bands and chocking.

ISPM-15 certificate from crate supplier.

Packing list showing crate dimensions, gross weight, net weight, and machine serial numbers.

This documentation is essential for any insurance claim and demonstrates that the machine left your facility in correct condition with correct packaging.

Real Story: Hadapsar Valve Equipment Exporter

A Hadapsar manufacturer of industrial valve testing rigs was exporting to a buyer in Saudi Arabia. Each rig weighed approximately 650 kg and had a precision hydraulic circuit and electronic control panel.

First two shipments used standard plywood boxes. First shipment: minor denting, accepted with complaint. Second shipment: cracked control panel housing, rejected.

Cost of rejection: Rs. 4.8 lakhs in repair and re-shipment. Next order from Saudi buyer: cancelled. Lost revenue: Rs. 12 lakhs.

After rebuilding the packaging system to custom seaworthy wooden crates with HDPE lining, foam cushioning on all surfaces, VCI wrapping of hydraulic components, and silica gel packets -- the next four shipments arrived without complaint. The Saudi buyer reinstated the contract.

Frequently Asked Questions

What timber thickness should a wooden crate be for machinery above 500 kg?

Use minimum 32mm hardwood or pine timber for crates carrying loads above 500 kg, with doubled timber at all corners and structural cross-bracing at the mid-span of each wall panel. For loads above 2,000 kg, consult a packaging engineer for structural specification.

Is ISPM-15 required for wooden crates used to export machinery?

Yes. Any wooden crate, pallet, or dunnage used in international sea freight from India must be ISPM-15 certified -- heat-treated at 56 degrees Celsius for 30 minutes minimum, with the official ISPM-15 mark burned or branded on the wood.

How do I prevent rust on machinery during sea freight?

Apply VCI (Volatile Corrosion Inhibitor) film, paper, or liquid to all exposed ferrous metal surfaces before packaging. Use a moisture barrier (HDPE tarpaulin or aluminium foil) inside the crate. Add silica gel desiccant at 2 to 3 units per cubic foot of internal volume. These three measures together provide complete corrosion protection for sea freight routes up to 35 days.
