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

Plain-English explanation

CSMS 65236374 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on June 3, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "UPDATED 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.

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 the Chapter 99 HTS. Report a second quantity (of the steel content) in kilograms with the Chapter 99 HTS. 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.  No drawback shall be available with respect to the duties imposed.   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 June 4, 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 June 4, 2025, and entered on or after 12:01 a.m. eastern daylight time on June 4, 2025, use the HTS classification below corresponding to the type of imported good:   · 9903.81.88/9903.81.95 (UK): Iron or steel products · 9903.81.93/9903.81.99 (UK) : Iron or steel derivative products, except as noted below:  o 9903.81.91/9903.91.98: Iron or steel derivative products classified outside of Chapter 73. o 9903.81.92: Iron or steel derivative products with a melt and pour of United States.   Application of Reciprocal Tariffs under EO 14257 As of June 4, 2025, the non-steel content of an article reported on a separate line per the instructions above is subject to Reciprocal tariffs under HTS 9903.01.25 (see also CSMS # 65201384).  The steel content subject to Section 232 duties per the instruction above is not subject to Reciprocal tariffs under HTS 9903.01.33.   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. For reference, a summary list of Section 232 Chapter 99 HTSUS classifications is attached. For questions regarding Section 232 entry filing, contact the Trade Remedy Branch at TradeRemedy@cbp.dhs.gov .

Frequently asked questions

What is CSMS 65236374?

CSMS 65236374 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "UPDATED 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 65236374 published?

CBP published CSMS 65236374 on June 3, 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.
