A government bureau has accused the United States Customs Service of being largely responsible for a lack of information about new trade regulations governing US-bound exports. The Commerce, Industry and Technology Bureau has asked US Customs officials to divert to Hong Kong on their way home from Japan where they are ironing out details of the Container Security Initiative, a trade-based anti-terrorism measure. 'We were a little disappointed with the quality of information provided by the last US Customs team to visit Hong Kong [two weeks ago],' the bureau's deputy secretary, Raymond Young Lap-moon, said. The government has been criticised for a perceived hands-off approach to a US Customs regulation, which from yesterday required maritime cargo manifests for US-bound goods to be electronically filed 24 hours before a vessel leaves port. Shippers have had up to 14 days to file manifests after vessels leave. With more than two million containers moving to the US from Hong Kong each year, it is feared the new regulation has the potential to disrupt the local supply chain. But Mr Young said the bureau was also in the dark about some of the finer details of the new requirement. '[US Customs] hasn't really been talking to us. They seem to think it is up to the business community trading with the US to figure out how they are going to comply,' said Mr Young. 'We don't believe that should be the case, and neither, apparently, does Japan or Singapore.' The new manifest regulation is a requirement for all shippers wanting their goods to have priority US Customs clearance. The manifest regulation took effect yesterday. Carriers have a grace period to February 3 to comply or face penalties including fines and US Customs delays.
