On the other hand, importers can manage compliance on their own. The law requires that importers act with reasonable care and define that, in part, as having internal customs experts. Corporate importers do this by having compliance managers to oversee import (and export) operations.
The problem is that many companies are part of families of related entities. Often, there is a corporate parent and multiple subsidiaries and possibly subsidiaries of subsidiaries. Usually, these companies are separate legal entities.
As you may have noticed, the economy has not been great. Many companies have reacted by working hard to consolidate resources and eliminate redundancy. On way to do that is to set up shared services. Where subsidiary A and subsidiary B both need import compliance managers, it might make sense to have the same person perform that task for both companies. But, according to Customs and Border Protection, an unlicensed employee of subsidiary A cannot conduct customs business on behalf of related subsidiary B because doing so is acting as a customhouse broker without a license.
