GUIDANCE: Import Duties on Imports of Steel and Steel Derivative Products

Plain-English explanation

CSMS 64348411 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (rate correction), published on March 7, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "GUIDANCE: Import Duties on Imports of Steel and Steel Derivative Products". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

Cargo Systems Messaging Service CSMS # 64348411 - GUIDANCE: Import Duties on Imports of Steel and Steel Derivative Products The purpose of this message is to provide guidance on the 25 percent import duty on all imports of steel articles and derivative steel articles from all countries effective 12:01 Eastern Daylight Time on March 12, 2025.  See 90 FR 9817 , February 18, 2025, and 90 FR 11249 , March 5, 2025. BACKGROUND On February 10, 2025, the President issued Proclamation 10896 on Adjusting Imports of Steel into the United States, under Section 232 of the Trade Expansion Act of 1962, as amended (19 U.S.C. 1862), imposing 25 percent ad valorem tariffs on all imports of steel articles and derivative steel articles from all countries, effective March 12, 2025.  See 90 FR 9817 and 90 FR 11249 . GUIDANCE Effective with respect to steel articles and derivative steel articles entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. Eastern Daylight Time on March 12, 2025, the following Harmonized Tariff Schedule of the United States (HTSUS) classifications and 25 percent duty rate apply: 9903.81.87: Iron or steel products listed in subdivision j (except derivative articles) 9903.81.88: Iron or steel products except for derivative articles listed in subdivision (l), (m) and (n) that are admitted to a U.S. foreign trade zone under “privileged foreign status” before March 12, 2025, and entered for consumption on or after March 12, 2025 . 9903.81.89: Derivative iron or steel products listed in subdivision (l) (existing steel derivative articles subject to Section 232). 9903.81.90: Derivative iron or steel products listed in subdivision (m) (new steel derivative articles classified in Chapter 73 subject to Section 232). 9903.81.93 : Derivative products of iron or steel, as specified in subdivisions (l) and (m) (existing derivative steel products, and new derivative steel products in Chapter 73) admitted to a U.S. foreign trade zone under “privileged foreign status” before March 12, 2025 , and entered for consumption on or after March 1, 2025 . Effective with respect to steel articles and derivative steel articles entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. Eastern Daylight Time on March 12, 2025, the following HTSUS classification and 0 percent duty rate applies: 9903.81.92: Derivative steel or iron products listed in subdivision (m) or (n) (new derivative steel articles) where the derivative iron or steel product was processed in another country from steel articles that were melted and poured in the United States. HTS 9903.81.92 also applies to such goods that were admitted to a U.S. foreign trade zone and granted “privileged foreign status” before March 12, 2025, and entered for consumption, or withdrawn from warehouse for consumption, on or after March 12 (see Foreign Trade Zone section below). Effective with respect to steel articles and derivative steel articles entered for consumption, or withdrawn from warehouse for consumption, on or after a date to be certified in the Federal Register by the Secretary of Commerce, the following HTS classification and 25 percent duty rate applies to the value of the steel content: 9903.81.91: Derivative iron or steel products listed in subdivision (n) (new steel derivative articles not classified in Chapter 73 subject to Section 232):  the import duty is on the value of the steel content (see instructions below). 9903.81.91 also applies to such goods that were admitted to a U.S. foreign trade zone and granted “privileged foreign status” before March 12, 2025, and entered for consumption, or withdrawn from warehouse for consumption, on or after a date to be certified in the Federal Register by the Secretary of Commerce (see Foreign Trade Zone section below). Reporting Instructions for Duties Based on Steel Content For new steel derivatives outside of Chapter 73, the 25 percent duty is to be reported with HTS 9903.81.91 based upon the value of the steel content.  If the value of the steel content is the same as the entered value or is unknown, the duty must be reported under HTS 9903.81.91 based on the entire entered value, and report on only one entry summary line. In the case where the value of the steel content is less than the entered value of the imported article, the good must be reported on two lines.  The first line will represent the non-steel content while the second line will represent the steel content.  Each line should be reported in accordance with the below instructions. Non-Steel content, first line: Ch 1-97 HTS, this same HTS must be reported on both lines. Country of origin, same must be reported on both lines. Total entered value of the article less the value of steel content. Report the total quantity of the imported goods. Report all other applicable duties, such as IEEPA tariffs and antidumping and countervailing duties . Steel content, second line: Same Ch. 1-97 HTS reported on the first line. Same country of origin reported on the first line. Report 0 for quantity for the Ch. 1- 97 HTS. Report the value of steel content. Report the Section 232 duties based on the value of steel content with HTS 9903.81.91. Report a second quantity (of the steel content) in kilograms with the HTS 9903.81.91. Report all other applicable duties, such as IEEPA tariffs and antidumping and countervailing duties. Melt and Pour Reporting Requirements The reporting of the country of melt and pour and applicability code is mandatory for both steel and steel derivatives.  To report the country of melt and pour, importers must report the International Organization for Standardization (ISO) code on steel articles and derivative steel articles subject to Section 232.  For steel articles, importer must report the ISO code where the steel was originally melted and poured.  For steel derivatives, importers must report the ISO code where the steel was originally melted or “OTH” (for other countries).  For products melted and poured in the United States, importers must indicate “US” as the country of melt and pour. Exclusions and Drawback Importer-specific product exclusions for Section 232 duties that are active in the Automated Commercial Environment (ACE) shall remain effective until their expiration date or until excluded product volume is imported, whichever occurs first.  All general approved exclusions (GAEs) shall expire on March 11, 2025, and products will be subject to 25 percent ad valorem duties on March 12, 2025. No drawback shall be available with respect to the duties imposed. Quotas All Section 232 tariff rate and absolute quotas shall expire on March 11, 2025.  All Section 232 tariff rate and absolute quotas entries must be presented to CBP during official office hours per 19 CFR 132.3, 8:30 a.m. to 4:30 p.m. local port time, on March 11, 2025.  Entries that do not achieve quota status by 4:30 p.m. local port time on March 11, 2025, do not qualify for the Section 232 quotas and must be refiled as non-quota entries on March 12, 2025. Foreign Trade Zone (FTZ) Any steel article or derivative steel article, except those eligible for admission under “domestic status” as defined in 19 CFR 146.43, that is subject to the duty imposed by this proclamation and that is admitted into a U.S. FTZ on or after 12:01 a.m. eastern daylight time on March 12, 2025, must be admitted and granted as “privileged foreign status” as defined in 19 CFR 146.41, and will be subject upon entry for consumption to any ad valorem rates of duty related to the classification under the applicable HTS subheading.  Any steel article or derivative steel article, except those eligible for admission under “domestic status” as defined in 19 CFR 146.43, that is subject to the duty imposed by this proclamation, and that was admitted into a U.S. FTZ and granted “privileged foreign status” as defined in 19 CFR 146.41, prior to 12:01 a.m. eastern daylight time on March 12, 2025, will likewise be subject upon entry for consumption to any ad valorem rates of duty related to the classification under the applicable HTS subheading added by this proclamation. For steel and steel derivative articles admitted into a U.S. foreign trade zone and granted “privileged foreign status” as defined in 19 CFR 146.41, prior to 12:01 a.m. eastern daylight time on March 12, 2025, and entered on or after 12:01 a.m. eastern daylight time on March 12, 2025, use the HTS classification below corresponding to the type of imported good: 9903.81.88: Iron or steel products (including those classified under GAEs). 9903.81.93: All iron or steel derivative products, except as noted below:  9903.81.91: Iron or steel derivative products classified outside of Chapter 73. 9903.81.92: Iron or steel derivative products with a melt and pour of United States. Reporting Multiple HTS Numbers For entry summary lines that include multiple HTS numbers, CBP requires that the duty be appropriately associated to the correct HTS. For example, if the entry is subject to 9903.81.87, then the 25 percent duty must be associated to 9903.81.87 when transmitting to ACE and when a printed 7501 is produced.  The 25 percent duty must not be combined with the duty reported on a different HTS within the entry summary line.  Further, duties across several required HTS numbers on a given entry summary line must not be combined and cannot be reported on only one HTS within the entry summary line. CBP expects full compliance from the trade community for accurate reporting and payment of the additional duties.  CBP will take enforcement action on non-compliance.

Frequently asked questions

What is CSMS 64348411?

CSMS 64348411 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "GUIDANCE: Import Duties on Imports of Steel and Steel Derivative Products". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 64348411 published?

CBP published CSMS 64348411 on March 7, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
