VFC are willing to serve customers 24/24 hours. However, in order to carry out fumigation tasks positively and meet full requirements, customers should inform VFC at least 24 hours (for container fumigation) before fumigation. In case customers have demand with large scale such as for warehouse fumigation or ship fumigation, VFC should be informed as soon as possible so that we can carry out study, technical consultancy if necessary in an effective way before fumigation.
