Import Application Clarification Form (IACF)

What is the Import Application Clarification Form?

The Import Application Clarification Form (IACF) is an official document used by customs authorities and trade agencies to request additional information or clarification on an import application that has been submitted but cannot be processed in its current state. The form serves as a structured communication tool that ensures the applicant provides the missing or ambiguous data needed for a decision on customs clearance, classification, valuation, or compliance.

When should the IACF be used?

• Incomplete documentation key invoices, certificates of origin, or permits are missing.
• Inconsistent information discrepancies between declared values, HS codes, or country of manufacture.
• Regulatory doubts questions about licenses, quotas, or antidumping measures.
• Technical queries need for product specifications, material composition, or safety data.

Customs will issue an IACF after an initial review and before any further enforcement action, such as detention or penalty assessment.

Who needs to complete the IACF?

The responsibility for completing the form falls on the party that submitted the original import application. This is usually:

1. Importer of Record (IOR)
2. Customs broker acting on behalf of the IOR
3. Authorized agent or freight forwarder, when they have power of attorney

Each signatory must have a valid electronic signature or a handwritten signature where paper submission is required.
