The Australian Wine and Brandy Corporation fears that the country's wine exporters face "expensive disruption" in the vital US market from new laws there to fight bio-terrorism.

Under draft US laws, from December, food and beverage manufacturers must register with the US Food and Drug Administration (FDA) and provide detailed records outlining the source and shipment details of all imports to the country.

On its website the AWBC said that this effectively meant that if exporters produce wine at their facility, bottle it at a contract facility and then store the wine in an off-site warehouse, then each of the three facilities need to be registered with the FDA.

The FDA will also demand that exporters inform it when exactly shipments are due to arrive - providing that information no more than five days and not less than eight hours before its actual arrival.

If exporters fail to follow these complex rules then they could have their wines refused entry to the US, have their merchandise seized and destroyed on arrival or face fines and de-registration.

"You must act now to review your current practices in order to avoid possible expensive disruption to your US exports from the end of this year," AWBC compliance manager Stephen Guy said on the website.
