In many export markets, cargo containers must be fumigated before loading onto vessels to eliminate the risk of pests being transported with the goods. To ensure treatment effectiveness and compliance with international quarantine regulations, VFC implements a strict container fumigation process using Methyl Bromide (CH₃Br), following controlled steps from survey and treatment to the issuance of a fumigation certificate.
1. Scope of Application
VFC’s container fumigation process is uniformly applied to export shipments requiring pest control before international transport.
Depending on the type of goods, destination market, and quarantine requirements, the treatment plan is adjusted to ensure:
- Compatibility with the nature of the goods.
- Compliance with the importing country's regulations.
- Safety during the treatment process.
For shipments to Australia, the process follows AFAS standards, strictly complying with the phytosanitary requirements of that market.
2. Steps in the Container Fumigation Process
Step 1: Receiving Fumigation Request:
VFC receives requests with details such as:
- Type of goods
- Destination market
- Container type (20', 40', etc.)
- Schedule
- Technical requirements
This information allows the technical team to prepare the most appropriate treatment plan from the outset.
Step 2: Survey and Treatment Planning
VFC technicians assess the shipment, including
- Suitability of the cargo for the fumigation method
- Packaging type
- Required fumigation duration
- Destination regulations (dosage, aeration, residue limits)
- Container integrity
Based on the survey findings, a tailored fumigation plan will be developed for each shipment.
Step 3: Execution
After the cargo is loaded into the container, VFC's technical team will perform fumigation according to the technical process:
- Install gas supply lines, concentration monitoring lines, and circulation fans.
- Close the container doors and seal ventilation holes or door gaskets (if necessary).
- Inject the fumigant CH₃Br – Methyl Bromide according to the prescribed dosage.
- Perform gas leak tests and rectify them if necessary.
- Post safety warning signs.
- Monitor and measure the gas concentration inside the container.
Step 4: Fumigation Duration
After gas injection, the container will be kept sealed throughout the fumigation period.
The fumigation period typically lasts from 24–48 hours, depending on:
- Type of goods
- Customer requirements
- Importing market regulations
Maintaining the container in a sealed state ensures the effectiveness of eliminating pests.
Step 5: Aeration and Safety Check
Upon completion of the fumigation duration and when the treatment concentration meets requirements, the container will be aerated.
The steps include:
- Open the container doors and remove sealing materials.
- Ventilate the air inside the container.
- Check the gas concentration using specialized equipment.
- Ensure the concentration reaches the safe threshold (TLV).
- Collect fumigation materials and remove warning signs.
After completion, the container is ready for the transport process.
Step 6: Issuance of Fumigation Certificate
After the treatment process is complete and all technical requirements are fully met, VFC will issue a Fumigation Certificate according to the regulations of the importing market.
This certificate is an important part of the export documentation, helping goods to be accepted and cleared smoothly at the destination port.

What is transparent fumigation? When technology replaces “Trust” in export operations
Transparent disinfection is becoming a new standard in export operations. Have you ever anxiously waited for a shipment without knowing whether it was actually treated correctly and at the right time? In reality, this is a critical step that directly affects customs clearance, yet it is often overlooked or carried out merely to complete paperwork and meet deadlines.
