Methyl Bromide Fumigation

Methyl bromide is the most widely used fumigant for quarantine purposes. It is favoured in many countries for plant quarantine because of its reputation.

Methyl Bromide (MBr) is a liquid under pressure that turns into a gas when released after heating. It is stored in cylinders or cans. MBr is highly penetrative, can kill insect eggs, highly toxic to a broad spectrum of insects and similar pests, and is lethal even in relatively short exposure periods (typically 24 hours for non-perishables).

Methyl Bromide (MBr) Fumigation is the only chemical treatment accepted for ISPM 15.


But there are some goods for which problems can occur when fumigated with Methyl Bromide. Exim Fumigation Service dose not recommend these goods to be fumigate by Methyl Bromide. In general, these are – Foodstuffs, Leather Goods, Woolens, Viscose rayon, Photographic chemicals, Paper, Rubber Goods, Vinyl, Furs, Feathers (especially in feather pillows), Rug Padding (Foam rubber, felts etc.), Charcoal, Cinder blocks, Activated carbon, Horsehair articles, Oil artworks, Sulfur-based paint, Cellophane, etc. Please Contact Us for further details about non-recommended goods.

Fumigation of Cargo Containers

Exim Fumigation Services is providing this most essential service for export consignmets since 2006. All containers are being fumigated under gas proof sheets unless it can be shown that they comply with the specified pressure test standard for gas-tightness.

This process are undertaken every time before any container is fumigated. The gas tightness are determined using a pressure decay test. This corresponds to a pressure halving (or decay) time from 200-100 Pa of 10 seconds or more. Containers that cannot be pressurised to 250 Pa (the starting pressure for the test) are deemed to have failed the test and will be enclosed under gas proof sheets before being fumigated with methyl bromide.

Selection and Inspection of Containers

The experts of Exim Fumigation Services are well efficient to inspect a container. We have a good reputation for inspecting the Empty Containers for many industries including Tea Exporters. We are helping our Tea Exporters for selecting “Tea Fit” containers for various countries at the container yard. Read more about our Container Selection and Inspection process.

Ship Hold Fumigation (Vessel Fumigation)

The experts of Exim fumigation Services are carrying out vessel fumigation using Methyl Bromide or Aluminium Phosphide. Our Team has fumigated so many import vessel containing wheat, maize, wooden logs etc. in Kolkata and Haldia port. We are equipped to carry out hot gas fumigation for entire bulk vessel with suitable gas circulation equipment.

Fumigation of ship is much more challenging than other type of fumigations, since a large quantity of gas is required to be released into the ship holds and further the space configuration will vary from ship to ship. The safety issue is of prime concern, while undertaking ship fumigation both at the time of gassing as well as at the time of aeration of ship holds.

Air Cargo Fumigation

In today’s fast moving world air cargo has to be rushed to various destinations across the glob. While despatching air cargo there is a need to take special attention to comply with the quarantine requirements with regards to wooden packing material and agro products.

Treatment for air cargo has to be carried out quickly in the the most effective mannerand after aeration it has to be moved for dispatch immediately. The Methyl Bromide Fumigation Service of Exim Fumigation Services is the best way to treat to comply all the quarantine requirements.

Degassing/aeration of commodity/container

On completion of our fumigation treatment we will vent the fumigant from the fumigation enclosure to below 5ppm v/v (the current Threshold Limit Value (TLV) for methyl bromide). This will be done through either natural airing or forced ventilation. Before anyone is allowed access to the fumigation enclosure the Exim Fumigation Services has the responsibility to take precautions to ensure that the area is free from hazardous levels of fumigant. Inadequately aerated goods threaten the health of workers involved in their unpacking and inspection.

Where there is no documentation showing that an enclosure or container has been vented, handlers should treat it as still ‘under gas’ until an approved Exim fumigation Services operator has cleared it as safe.

Fumigation Certificate

At the end of successful fumigation, our approved fumigation operator will issue a fumigation certificate in the prescribed format in conformation with the Methyl Bromide Fumigation Standard of Govt. of India / Australia.
