When exporting heavy machinery, industrial equipment, or large vehicles, overweight container shipping requires more than simply loading cargo. It demands engineering planning, verified weights where required by regulation, and careful compliance with international and U.S. transport rules. Under the International Maritime Organization’s SOLAS convention, many containerized exports require a Verified Gross Mass (VGM) declared by the shipper before vessel loading. Carriers and terminals follow these rules to plan safe stowage.
Express Packing specializes in overweight container shipping solutions that meet these rigorous requirements. Below, you’ll discover how we manage the challenges of heavy shipments, the industries we support, and why we are a trusted partner for complex logistics.
Expertise in Oversize & Overweight Packing
Express Packing has successfully packed and shipped machinery in excess of 200,000 pounds, working in conjunction with rigging companies and providing engineering support to size materials and plan securement.
Our approach ensures safety, compliance, and efficiency across every shipment.
- Engineering-driven packing: Load distribution is calculated to protect container integrity and comply with port and highway regulations.
- Collaborative execution: We partner with rigging companies, engineers, and port authorities both domestically and internationally.
- Proven track record: Complex lifts and oversized loads are executed with precision, safeguarding both cargo and container.
Note on container ratings: Standard ISO containers can be rated up to 79,370 lb (36,000 kg) maximum gross mass, depending on the box. Operational limits for road/rail or specific carriers may be lower. We align our packing and loading plans to those constraints.
Decades of Specialized Experience
Our team brings 50+ years of packing and transport experience. We provide engineering support to size bracing, blocking, and cribbing and to plan load distribution that protects both cargo and container.
Collaboration with Rigging and Lifting Specialists
Loading large, irregular, or extremely heavy machinery requires specialized rigging equipment and trained professionals.
- Overhead cranes & forklifts: Used for high-tonnage lifts requiring precise placement.
- Custom jacking systems: Allow for careful adjustments during loading.
- Balance & stability: Cargo is always positioned to maintain center of gravity and protect the container.
This collaboration ensures seamless transfer from factory floor to port, minimizing risks of damage or imbalance.
Container Blocking and Bracing Services
Once heavy cargo is loaded, proper securing is non-negotiable. Express Packing designs container blocking and bracing tailored to each shipment, including cars and machinery, to prevent fore-aft and lateral movement.
- Custom-fit materials: We use wood, steel, and engineered supports depending on cargo type.
- Blocking: Prevents forward or backward shifting.
- Bracing: Restrains side-to-side movement, especially critical in ocean conditions.
- Vehicle immobilization: Wheels are locked with chocks and straps, then braced directly to container walls.
Preventing Cargo Shift and Damage
Misdeclared or unbalanced container weights have been linked to stack collapses and lost containers at sea; accurate declarations and robust securement are essential. We follow recognized securement practices to keep loads stable through ocean, rail, and truck moves.
To prevent this, our methods include:
- Multi-step securing: Vehicles, turbines, and equipment are locked in place with redundancy.
- Custom cages and pallets: Non-wheeled items are independently supported.
- Best-practice compliance: We follow international guidelines on blocking and bracing to protect vessels, ports, and infrastructure.
Compliance with Export and Container Safety Standards
We coordinate with customers and carriers to ensure weight declarations and documentation meet applicable requirements (including SOLAS VGM where required) and that container rated limits are observed alongside U.S. highway weight rules (e.g., 80,000 lb GVW and axle limits, subject to state variations and permits).
Why Overweight Container Shipping Requires Expertise
Shipping overweight containers is one of the most regulated aspects of international logistics. The risks of mishandled cargo extend from financial losses to serious safety hazards.
- Maritime safety: Overloaded or unbalanced containers can destabilize vessels, collapse stacks, and cause containers to go overboard
- Highway enforcement: Trucks exceeding 80,000 lbs gross vehicle weight or axle-specific thresholds face fines and possible forced offloading
- Permit variability: Different states apply different rules. For example, Illinois allows loads up to 98,000 lbs with a permit, while neighboring states may allow less
The result is a complex regulatory environment that requires experienced planning to navigate without delays or unexpected costs.
Consequences of Misdeclared or Unbalanced Loads
Failing to declare container weight accurately is a leading cause of maritime accidents and cargo liability claims.
- Safety concerns: Workers, seafarers, and port staff face injury or death risks when overweight containers collapse or fall.
- Structural damage: Ships, cranes, and container chassis can suffer costly damage from unbalanced loads.
- Infrastructure impact: Overweight trucks accelerate road wear and can harm bridges and pavements, leading to strict enforcement.
Express Packing mitigates these risks by combining accurate documentation with precision-engineered bracing that keeps every load stable across ocean, rail, and truck transport.
Specialized Materials and Precision Engineering
Handling extreme weights often requires more than timber and nails. Our engineers employ advanced design and reinforced materials to meet structural demands.
- Steel-reinforced cradles: Transfer weight across multiple points.
- High-strength fasteners: Engineered to withstand intermodal transport stresses.
- Structural modeling: Simulation tools predict stress points before fabrication.
- Custom-engineered skids: Designed for irregularly shaped machinery like turbines and transformers.
These solutions balance compliance with cost-efficiency, ensuring your cargo travels safely without exceeding budget.
Industries We Serve
Our overweight container shipping services support a wide range of industries with unique logistical challenges.
Heavy Machinery & Industrial Equipment
Manufacturers of turbines, presses, mining equipment, and production lines trust us to design crates and bracing systems that withstand the stresses of international shipping.
Automotive and Vehicle Exporters
From sedans to buses, we immobilize wheels, secure vehicles to container walls, and prevent panel damage during long voyages. Non-wheeled machinery shipped alongside vehicles is braced independently for added safety.
Construction, Energy, and Infrastructure
We handle heavy-duty equipment like generators, transformers, wind turbine blades, and drilling rigs. Our custom-built skids and bracing protect both delicate and oversized parts.
Aerospace and Defense
Shipping aircraft parts and defense systems requires both precision and regulatory compliance. We design secure containers, coordinate inspections, and ensure adherence to hazardous materials and export control requirements.

FAQs
What is the maximum weight limit for a standard shipping container?
ISO-standard containers can be rated up to 79,370 lb (36,000 kg) maximum gross mass; actual allowable payload depends on the container’s tare and local road/rail limits or carrier rules.
Why is Verified Gross Mass (VGM) required?
To support safe stowage/stacking and prevent incidents linked to misdeclared weights under SOLAS rules.
What permits are needed for overweight trucking?
State-issued permits vary. Example: Illinois may permit gross weights near 98,000 lb on specified configurations/routes. Requirements vary by state and axle layout.
How do you secure vehicles inside containers?
Vehicles are immobilized using wheel chocks or straps, then braced to the container’s structure to prevent any shifting during transit.
