Selecting the best rust preventative for overseas shipments is critical. This is because long-distance transport exposes metal parts to some of the most aggressive corrosion risks. These include high humidity, salt air, temperature fluctuations, and condensation commonly known as container rain. As a result, without the right protection strategy, corrosion can begin long before parts reach their destination.
While desiccants are frequently used during export shipping, they only manage moisture and do not actively protect metal surfaces. Furthermore, for extended transit times, desiccants alone are often insufficient. To truly prevent corrosion, manufacturers must choose the best rust preventative for overseas shipments based on metal type, packaging method, cleaning process, and expected exposure duration.
Why Rust Preventative Liquids are Essential for Overseas Shipping
Rust preventative liquids form a direct protective barrier on metal surfaces. This barrier blocks moisture, oxygen, and corrosive contaminants from initiating the corrosion process. In overseas shipments, environmental conditions can change rapidly. Consequently, this surface protection plays a critical role.
Products such as ZERUST® Axxanol™ oil-based rust preventatives and ZERUST® Axxatec™ water-based liquids are commonly used to protect parts immediately after machining or washing. Additionally, these rust preventative liquids are engineered to withstand humid and salt-laden environments. At the same time, they maintain clean removability at the destination.

Combining Liquids with VCI Packaging for Maximum Protection
The best rust preventative for overseas shipments is rarely a single product. Instead, it is a system. ZERUST®/EXCOR® recommends combining rust preventative liquids with Vapor Corrosion Inhibitor packaging technologies.
After a rust preventative liquid is applied, ZERUST® VCI packaging films, papers, or emitters release corrosion-inhibiting vapor inside the package or container. These vapor molecules diffuse throughout the enclosed space. As a result, they form an invisible protective layer on exposed metal surfaces, including internal cavities and hard-to-reach areas. This dual approach protects both the surface and the surrounding environment during long ocean transits.
How ZERUST® Determines the Best Solution for Export Shipments
The ideal rust prevention strategy depends on several factors. These factors include metal composition, part geometry, residual moisture, packaging configuration, and total shipment duration. Through the ZERUST® Z-CIS® Corrosion Inhibiting System methodology, ZERUST® specialists evaluate each step of the process. This includes part washing and drying, final packaging, and container loading.
By identifying corrosion risk points early, ZERUST® helps manufacturers implement the most effective and cost-efficient corrosion protection plan. This process-driven approach ensures that the best rust preventative for overseas shipments is selected for each specific application. Therefore, it does not rely on a one-size-fits-all solution.
Proven Corrosion Protection for Long Ocean Transits
When rust preventative liquids are combined with VCI packaging and proper process controls, metal parts remain clean, dry, and corrosion-free throughout extended overseas shipments. This layered protection significantly reduces damage claims, rework costs, and delays at the destination.
For application-specific guidance, manufacturers can contact ZERUST®/EXCOR® to speak with a technical service representative. The representative can recommend the most effective corrosion prevention system for their export needs.
