On February 4, 2022, in Cargo Systems Messaging Service (CSMS) #50930928, U.S. Customs and Border Protection (CBP) issued a reminder that “steel mill certificates, statements of metal components of aluminum, and (for entries from the European Union) aluminum certificates of analysis are required to be submitted at the time of importation for steel and aluminum, imports, respectively,” to the Document Imaging System (DIS).

This requirement applies to iron or steel imports “classifiable in Chapter 72 or headings 7301 to 7307 of the HTSUS” and “aluminum and alloys of aluminum imports classifiable under subheadings 7601.10.60, 7601.20.60, 7601.20.90, or 7602.00.00.”

Effective January 1, 2022, imports of aluminum articles from the European Union must include a certificate of analysis to be eligible for the Section 232 tariff rate quota (TRQ).
