Why Fumigation is Essential in Freight Shipping

Understanding the Role of Cargo Fumigation in Freight Transport


Most countries require cargo fumigation before goods can be imported. But what exactly is this process, and why is it so critical for global safety? Let’s delve into the ins and outs of container fumigation.

The Imperative of Cargo Fumigation

As cargo is prepared, loaded, and set for shipment to its destination, various fumigation techniques are employed. This procedure is crucial to eradicate any harmful living organisms like disease carriers or invasive creatures, from termites to flies.

This is the primary reason why a majority of countries make it compulsory for carriers and shippers to ensure container fumigation before loading and transporting cargo. Only through collaborative international measures can we continue to prevent these pests from spreading.

Fumigation refers to the methods used to wipe out pests within a specific container or cargo using efficient fumigants. After this operation is completed, the fumigation company issues a certificate. This document serves as proof to customs officers that the cargo fumigation has been performed following best global practices.

Carriers and shippers present these certificates as evidence that cargo has been fumigated. These certificates detail the cargo fumigation processes, its purpose, temperature range, and the fumigants used. Cargo and container fumigation is a requirement for international shipping under the IMO International Maritime Dangerous Goods Code, and it’s also mandated by national governments.

Unraveling the Fumigation Process

Certain types of packaging, notably wooden packaging, are highly susceptible to pest infestations and parasites. These materials create an ideal environment for pests to breed and multiply, with common culprits including the Asian Gypsy Moth, Asian Lady Beetle, and the Toxic Cane.

There exists a variety of fumigation techniques, each varying in effectiveness and duration, depending on the specific gas used. The most commonly utilized gases are methyl bromide and phosphine. Both are effective, but methyl bromide often takes precedence for shipping containers.

During fumigation, not just the container but also a five-meter radius around it is cleared to prevent human contact with potentially harmful chemicals.

The assigned fumigation company will delegate a fumigator-in-charge, who has the necessary documentation that attests to their proficiency. This professional provides essential information such as the type of gas used and the associated health hazards. They also offer guidance on the most appropriate treatment method and exposure time. After the cargo is properly fumigated, they generate the legally required certificates, facilitating buyers to import goods into their countries.

Instances When Container Fumigation Isn’t Required

The UN agency, ISPM-15, is responsible for establishing regulations to prevent the spread of invasive species. This organization identifies the materials that need fumigation and those that do not. Man-made materials, cardboards, and plastic palettes do not require fumigation, which is why shippers often prefer non-wood materials.

Exemptions to fumigation include:

  • Standard Plastic Pallets: These are durable and don’t have the hygiene issues associated with wooden pallets. They also sidestep the pest treatments needed for international shipping.
  • Presswood pallets (materials like sawdust, wood wool, wood shavings, recycled wood)
  • Wood packaging made entirely of processed materials
  • Barrels (used for wine and spirits) that have been heated during manufacture
  • Euroblock pallet blocks (made from wood fiber)
  • Small wood components that are permanently attached to freight vehicles and containers

    Different Fumigation Methods for Shipping Safety

    Fumigation plays a crucial role in ensuring the safety of goods during shipping by preventing pest infestation. There are two primary methods of fumigation:

    Full Container Load (FCL) Fumigation: This method involves the fumigation of an entire load of goods contained within a shipping container. The fumigant is trapped within the container for a specific duration to allow thorough circulation, enhancing the effectiveness of the process. Once fumigation is completed, the container doors are sealed, and the cargo is prepared for shipping.

    Partial Container Load Fumigation: In some instances, the cargo requiring fumigation does not occupy the full container. In such cases, plastic sheets are used to cover the cargo, forming a contained area for the fumigant. After the predetermined exposure time, the sheets are removed, and the space is ventilated. Alternatively, containers can be fumigated before they are loaded with cargo.

    Importance of Fumigation in Maintaining Shipping Safety

    Fumigation is a critical step in ensuring the safe transportation of goods. It helps shippers comply with the safety standards necessary for exporting and importing goods. If you’re planning to ship products internationally, it’s essential to understand the fumigation requirements in the origin and destination countries.

    Freight forwarders can provide valuable insight into these requirements. As experienced professionals in shipping, they are knowledgeable about the regulations enforced by customs authorities and other entities that manage international goods movement. Always consult your freight forwarder to ensure your shipment complies with all necessary fumigation controls and regulations.
