U.S. Customs Form: CBP Form 400 – ACH Application

U.S. Customs and Border Protection Form 400 is used by importers and customs brokers to apply for Automated Clearing House (ACH) services. This allows you to send and receive funds to customs directly from your bank account without incurring the 2% typically imposed by credit cards and other payment methods, while still having the ability to transfer the funds instantly.
