The importation of goods is a complex task, with many quirks and regulations. For that reason, many companies use third parties (such as customhouse brokers or freight forwarders) to handle the numerous details.
As it seems you're keen on setting up things properly, speak to an attorney who understands the import process and has experience in this area. He or she should be able to clue you in on what's involved.
