How Do You Ship Heavy Low-Bed Trailers from China to New Zealand? A 40FT Flat Rack and OOG Cargo Case Study
Case Study Summary
How do you transport heavy low-bed trailers that cannot fit inside standard shipping containers?
NewAsian Logistics coordinated the ocean freight shipment of two 3-axle detachable gooseneck low-bed trailers from Shanghai, China, to Auckland, New Zealand.
The shipment had a total gross weight of 41,280 kg and a total measurement of 99.72 CBM. Each trailer was loaded as one package on a 40FT Flat Rack container, with a declared gross weight of 20,640 kg and a measurement of 49.86 CBM per unit. Because of their size, weight and structural configuration, the trailers required specialised Flat Rack and Out-of-Gauge cargo planning rather than standard enclosed container shipping.
This case study provides practical guidance for businesses planning to import heavy machinery, trailers and oversized goods from China to New Zealand.

What Was the Shipping Challenge?
Transporting heavy equipment internationally involves much more than booking ocean freight. Oversized cargo requires coordinated planning across international shipping, customs compliance and final delivery. For this project, NewAsian Logistics managed the transportation of two 3-axle detachable gooseneck low-bed trailers from Shanghai, China to Auckland, New Zealand.
The project required coordination across multiple logistics stages, including:
- Selecting suitable 40FT Flat Rack containers for heavy equipment.
- Planning safe loading and cargo securing before export.
- Coordinating international ocean freight from China to New Zealand.
- Completing New Zealand import customs clearance.
- Arranging container collection from the Auckland port terminal.
- Coordinating door-to-door delivery to the customer’s premises.
- Organising professional on-site unloading and container de-stuffing.
- Managing communication across multiple service providers while meeting the customer’s delivery schedule.
Rather than treating these as separate transport activities, NewAsian Logistics managed the shipment as a single end-to-end logistics project, providing one coordinated solution from origin to final delivery.

What Is a 40FT Flat Rack Container and When Should It Be Used?
A 40FT Flat Rack container is a specialised shipping container designed for cargo that cannot be loaded into a standard enclosed container due to its width, height, length or weight. Unlike a standard container, a Flat Rack has no side walls and no fixed roof, providing an open loading platform for oversized and heavy equipment. It is commonly used for:
- Low-bed trailers
- Construction machinery
- Mining equipment
- Industrial tanks and pressure vessels
- Steel structures
- Heavy project cargo
For this shipment, a 40FT Flat Rack was selected because the detachable gooseneck low-bed trailers could not be transported safely inside a standard dry container. The open structure of the Flat Rack allowed safe loading, cargo securing and heavy-lifting operations while supporting the required cargo weight.
It is important to distinguish Flat Rack containers from Out-of-Gauge (OOG) cargo.
- A Flat Rack is a type of shipping equipment.
- Out-of-Gauge (OOG) describes cargo that exceeds the standard internal dimensions of a shipping container.
Therefore, the correct industry description for this shipment is: Two Out-of-Gauge (OOG) low-bed trailers transported on two 40FT Flat Rack containers.
Project Outcome
The shipment was successfully completed with end-to-end logistics coordination by NewAsian Logistics. Key project outcomes included:
- Successfully transported two 3-axle detachable gooseneck low-bed trailers from Shanghai, China to Auckland, New Zealand.
- New Zealand import customs clearance was completed smoothly with compliant documentation.
- The total transit time was 28 days from departure to arrival.
- Door-to-door delivery was arranged to the customer’s designated site in New Zealand.
- Professional unloading support was coordinated on-site to ensure the trailers were safely discharged from the Flat Rack containers.
- The project was completed through a single coordinated logistics solution, covering international ocean freight, customs clearance, final delivery and on-site cargo handling.
This project demonstrates NewAsian Logistics’ capability in managing heavy equipment, Flat Rack container shipping and importing oversized goods from China to New Zealand through an integrated logistics solution.

Business Insight
Heavy equipment imported from China often requires more than international shipping. Businesses should plan container selection, customs clearance, port collection and final delivery together to reduce delays and improve supply chain efficiency.

Frequently Asked Questions
Can a low-bed trailer fit inside a standard shipping container?
Usually not as a complete unit. Its length, width, weight and axle structure may require Flat Rack, RoRo or breakbulk shipping. Partial dismantling may create other transport options.
What documents are required to import heavy trailers from China to New Zealand?
The documents required to import heavy trailers from China to New Zealand typically include:
- Commercial invoice
- Packing list
- Bill of lading
- Trailer specifications and technical information
- Manufacturer or supplier details
- Import declaration and supporting customs documents
- Any certificates, permits or compliance documents required for the specific trailer type
The exact documentation requirements depend on whether the trailer is new or used, its intended use, technical specifications and New Zealand import and compliance requirements.
