GUIDANCE – Reciprocal Tariffs, April 5, 2025 Effective Date

Plain-English explanation

CSMS 64649265 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (rate correction), published on April 4, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "GUIDANCE – Reciprocal Tariffs, April 5, 2025 Effective Date". 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 # 64649265 - GUIDANCE – Reciprocal Tariffs, April 5, 2025 Effective Date The purpose of this message is to provide guidance on the additional duties due on imported merchandise which were imposed by Executive Order, “Regulating Imports with a Reciprocal Tariff to Rectify Trade Practices that Contribute to Large and Persistent Annual United States Goods Trade Deficits,” issued on April 2, 2025. This guidance applies to the actions that are effective on April 5, 2025.  CBP will issue separate guidance for the actions that are effective on April 9, 2025.  GUIDANCE CHAPTER 99 SECONDARY CLASSIFICATION REQUIRED With the implementation of the above Executive Order, effective April 5, 2025, filers must report at least one Harmonized Tariff Schedule of the United States (HTSUS) Chapter 99 secondary classification related to the reciprocal tariffs.  All imported merchandise must be reported with either the HTSUS classification under which the reciprocal tariff applies or one of the HTSUS classifications pursuant to which the merchandise is excepted from the reciprocal tariff. APPLICATION OF ADDITIONAL DUTY RATES All imported goods, other than those that fall within the identified exceptions, entered for consumption, or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern daylight time (EDT) on April 5, 2025 , are subject to the following Harmonized Tariff Schedule of the United States (HTSUS) secondary classification and duty rate: 9903.01.25:   Additional ad valorem duty rate of 10% The additional rates of duty established by reciprocal tariffs are in addition to any other duties, taxes, fees, exactions and charges that apply to imported articles. EXCEPTIONS Until further notice, for all imported merchandise that is entered for consumption, or withdrawn from warehouse for consumption on or after 12:01 a.m. EDT on April 5, 2025, and for which an HTSUS classification is required to be declared, if the secondary classification under heading 9903.01.25 is not declared, then one of the following HTSUS secondary classifications must be declared, to specify the particular exception pursuant to which the reciprocal tariff in heading 9903.01.25 does not apply to the imported articles that are excluded from the additional ad valorem duties: 9903.01.26:    Articles the product of Canada, including those products of Canada entered free of duty as under the United States-Mexico-Canada Agreement, including any treatment set forth in subchapter XXIII of chapter 98 and subchapter XXII of chapter 99 of the HTSUS.  Articles properly classified in 9903.01.10 through 9903.01.15 should declare a secondary classification under 9903.01.26 in order to be excepted from the reciprocal tariff. 9903.01.27:    Articles the product of Mexico, including those products of Mexico entered free of duty as under the United States-Mexico-Canada Agreement, including any treatment set forth in subchapter XXIII of chapter 98 and subchapter XXII of chapter 99 of the HTSUS.  Articles properly classified in 9903.01.01 through 9903.01.05 should declare a secondary classification under 9903.01.27 in order to be excepted from the reciprocal tariff. 9903.01.28:    Articles the product of any country that were (1) loaded onto a vessel at the port of loading and in transit on the final mode of transport prior to entry into the United States before 12:01 a.m. EDT on April 5, 2025, AND (2) are entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. EDT on April 5, 2025. To prevent importers from abusing the exception for goods that were in transit before April 5, 2025 when it is no longer realistic due to the passage of time, CBP will permit heading 9903.01.28 to be declared only for goods that are entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. EDT on April 5, 2025, and before 12:01 a.m. EDT on May 27, 2025. 9903.01.29:    Articles the product of any Column 2 rate country identified in general note 3(b); currently limited to Belarus, Cuba, North Korea and Russia. 9903.01.30:   Articles that are donations, by persons subject to the jurisdiction of the United States, of articles, such as food, clothing, and medicine, intended to be used to relieve human suffering. 9903.01.31:   Articles that are informational materials, including but not limited to, publications, films, posters, phonograph records, photographs, microfilms, microfiche, tapes, compact disks, CD ROMs, artworks, and news wire feeds. 9903.01.32:    Articles of any country, classified in the subheadings enumerated in the subdivision (v)(iii) of U.S. note 2, identified in Annex II .  The only merchandise that is eligible for this exception is that which is listed in Annex II.  9903.01.33:    Articles of iron or steel, derivative articles of iron or steel, articles of aluminum, derivative articles of aluminum, passenger vehicles (sedans, sport utility vehicles, crossover utility vehicles, minivans, and cargo vans) and light trucks and parts of passenger vehicles (sedans, sport utility vehicles, crossover utility vehicles, minivans, and cargo vans) and light trucks, of any country, subject to Section 232. actions. 9903.01.34:    For articles in which at least 20% of the value of article is U.S. originating, the U.S. content will not be subject to the reciprocal tariff. The reciprocal tariff will be assessed on the non-U.S. content. (See below for reporting instructions.) CHAPTER 98 The additional duties imposed by the headings above shall not apply to goods for which entry is properly claimed under a provision of chapter 98 of HTSUS pursuant to applicable U.S. Customs and Border Protection (CBP) regulations, and whenever CBP agrees that entry under such a provision is appropriate, except for goods entered under heading 9802.00.80; and subheadings 9802.00.40, 9802.00.50, and 9802.00.60. For subheadings 9802.00.40, 9802.00.50, and 9802.00.60, the additional duties apply to the value of repairs, alterations, or processing performed, as described in the applicable subheading. For heading 9802.00.80, the additional duties apply to the value of the article assembled abroad, less the cost or value of such products of the United States, as described. FOREIGN TRADE ZONE Subject articles, excluding those encompassed by 50 U.S.C. 1702(b), except those that are eligible for admission to a foreign trade zone under "domestic status" as defined in 19 CFR 146.43, and are admitted into a United States foreign trade zone on or after 12:01 a.m. EDT on April 9, 2025, must be admitted as "privileged foreign status" as defined in 19 CFR 146.41. Such articles will be subject, upon entry for consumption, to the duties imposed by this order and the rates of duty related to the classification under the applicable HTSUS subheading in effect at the time of admission into the United States foreign trade zone. DRAWBACK Drawback is available with respect to the additional duties imposed pursuant to the Executive Order. DE MINIMIS Until further notice, except as otherwise provided in the April 2, 2025 Executive Order, “Further Amendment to Duties Addressing the Synthetic Opioid Supply Chain in the People’s Republic of China as Applied to Low-Value Imports”, the administrative exemption from duty and certain taxes at 19 U.S.C. 1321(a)(2)(C), known as the de minimis exemption, continues to be available for articles covered by headings 9903.01.25 and that are otherwise eligible for the exemption, including eligible articles sent to the United States through the international postal network. REPORTING For entry summary lines that include multiple HTSUS numbers, CBP requires that the duty be appropriately associated to the correct HTSUS. For example, if the entry is subject to 9903.01.25, then the 10% percent duty must be associated to 9903.01.25 within the entry summary line when transmitting to ACE and when a printed 7501 is produced. The 10% duty must not be combined with the duty reported on a different HTSUS within the entry summary line. Further, duties across several required HTSUS numbers on a given entry summary line must not be combined and cannot be reported on only one HTSUS within the entry summary line. For articles that have a U.S. content of at least 20 percent and are subject to 9903.01.34, the article must be broken up onto two entry summary lines to accurately report and pay the applicable rate of duty.  The reciprocal tariff additional duty is to be reported based on the non-U.S. content.    The first line will include the U.S. content while the second line will include the non-U.S. content. Each line should be reported in accordance with the below instructions. In the first line, for U.S. content, report: Ch 1-97 HTSUS, this same HTSUS must be reported on both lines. Country of origin, same must be reported on both lines.  HTSUS 9903.01.34. Total entered value of the article less the value of the non-U.S. content. Total quantity of the product.  All applicable duties. In the second line, for non-U.S. content, report: Same Ch. 1-97 HTSUS reported on the first line. Same country of origin reported on the first line.  HTSUS 9903.10.25. Total entered value of non-U.S. content of the article. Zero for quantity for the product. All applicable duties. HTSUS SEQUENCE For entry summary lines including multiple HTSUS numbers, the following sequence must be followed. 1. Chapter 98 (if applicable) 2. Chapter 99 number(s) for additional duties (if applicable) 3. For trade remedies, first report the Chapter 99 for Section 301, followed by the Chapter 99 for IEEPA Fentanyl, followed by the Chapter 99 for IEEPA Reciprocal, followed by the Chapter 99 for Section 232 or 201 duties (if applicable), f

Frequently asked questions

What is CSMS 64649265?

CSMS 64649265 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "GUIDANCE – Reciprocal Tariffs, April 5, 2025 Effective Date". 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 64649265 published?

CBP published CSMS 64649265 on April 4, 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.
