For exporters, an “OOG (Out of Gauge) Freight Forwarder” isn’t just a booking intermediary—it’s a logistics partner with engineering precision. When your cargo exceeds standard container dimensions in length, width, or height, traditional container handling fails. What you need are specialized containers (Flat Rack/Open Top) or breakbulk solutions tailored for oversized shipments.
In today’s volatile shipping market, factory managers and project leaders worry less about freight rates and more about uncontrollable risks: special container bookings canceled without notice, hidden high port lifting fees, or unprofessional third-party trucking that damages cargo before it reaches the port.
As an Alibaba-designated service provider, Heigten leverages its Shenzhen headquarters, in-house fleet, and AEO-certified customs brokerage to deliver door-to-port logistics. Every piece of large-scale machinery reaches the sea safely and on time.
If standard container shipping is like taking a public bus, OOG transport is a customized private escort.
OOG cargo usually refers to construction machinery, precision equipment, vehicles, or yachts too large or heavy to fit into standard 20GP or 40HQ containers.
Standard Forwarders vs. Specialized Project Forwarders
Many general forwarders lack the technical competence to handle OOG cargo. Common issues include insufficient knowledge of center-of-gravity calculations and lashing & securing standards, which can create safety risks during sea transport.
Heigten’s Core Advantage: Full-Chain Asset Control
Oversized cargo freight forwarding
In logistics, “assets are king”—the key to service quality. Unlike paper-forwarders that only handle documents, Heigten stands out by controlling critical nodes of the logistics chain.
Transporting oversized cargo starts at the factory gate. For ultra-wide or tall equipment, finding low-bed trailers and experienced drivers is essential.
Own assets, flexible dispatch: Our in-house fleet allows immediate response to late-night pickups or urgent rerouting. Transparent pricing—no middleman markups.
Full cargo coverage: In addition to standard container transport, we have hazardous cargo certification, enabling “one-truck delivery” for OOG cargo that is also classified as dangerous goods, reducing handoff risks.
AEO-Certified Customs Brokerage: The “Green Lane”
Customs clearance efficiency determines whether cargo meets its shipping schedule. Oversized or complex equipment often triggers inspections.
AEO accreditation: Our subsidiary has over ten years of experience and is AEO Advanced-certified, enjoying lower inspection rates and priority clearance in China.
Complex cargo expertise: From dismantled equipment to license-restricted goods, our customs experts identify risks in advance.
Case Example: Even for non-OOG high-priority shipments, our customs capability ensures timely clearance. During durian import peak season, we cleared multiple large-container shipments rapidly—demonstrating our ability to handle all high-value cargo with precision.
Alibaba Designation & Global Network
As an Alibaba International Station designated logistics service provider, we process tens of thousands of export orders annually. This confirms operational reliability and financial stability.
Beyond China, our global agent network solves complex destination port issues (DDP/DAP).
Automotive Export Case: We coordinated multi-batch mixed vehicle shipments using our Shenzhen headquarters and global network. Standardized solutions covered battery declaration, lashing, and port clearance for vehicle exports.
OOG Sea Freight Solutions
Heigten provides customized ocean shipping strategies based on cargo drawings and packing lists, not just buying container space.
Specialized Containers: Flat Rack (FR) & Open Top (OT)
Ideal for medium-sized construction machinery (excavators, bulldozers) and industrial equipment.
Open Top (OT): For over-height cargo within standard length & width. Loaded vertically with cranes and protected with high-strength tarpaulin.
Flat Rack (FR): For cargo exceeding height and width limits. No side walls or top cover; requires expert lashing & securing to prevent movement at sea.
Technical Advantage: Long-term contracts with COSCO, CMA, MAERSK allow priority access to special containers and competitive OOG rates through precise pre-declaration.
Oversized cargo freight forwarding
Breakbulk & RO-RO Shipping
For cargo too large for special containers (e.g., giant wind turbine blades, tanks, or full assembly lines), or self-powered cargo (trucks, cranes).
RO-RO: Vehicles drive directly on board; minimal risk, lower cost than breakbulk.
Breakbulk: Cargo lifted onto deck or hold; available at major ports including Tianjin, Shanghai, Guangzhou, and Ningbo.

Case Study: One-Stop Handling of Large Precision Machinery
Project Background: A Shenzhen manufacturer needed to export a precision injection molding machine to the U.S., width 3.8m, extremely vibration-sensitive. Previous forwarders could not provide air-cushioned transport or direct port loading.
Heigten Solution:
Inland Haulage
Used in-house low-bed air-cushion trailers, controlling vibration safely from factory to Yantian Port.
Port Handling
Leveraged AEO status to request direct truck-to-ship loading, reducing terminal handling and stacking risks.
Sea Lashing
On 40FR flat rack, the team applied military-grade straps and timbers in an “X” pattern, documented with photos sent to the client for confirmation.
Result:
Zero damage upon arrival at Los Angeles.
Pre-filed U.S. ISF (10+2) ensured smooth port clearance without delays.
