Plain-English explanation

CSMS 64235342 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on February 25, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Updated Guidance – Additional Duties on Imports from China and Hong Kong".

CSMS # 64235342 - Updated Guidance – Additional Duties on Imports from China and Hong Kong U.S. Customs and Border Protection sent this bulletin at 02/25/2025 05:07 PM EST Cargo Systems Messaging Service CSMS # 64235342 - Updated Guidance – Additional Duties on Imports from China and Hong Kong The purpose of this message is to provide the trade community with updated guidance for the additional duties for imports that are the products of China, pursuant to the Imposing Duties to Address the Synthetic Opioid Supply Chain in the People’s Republic of China Executive Order issued on February 1, 2025. UPDATE : CBP will reject entry summaries that are not in compliance with the requirements of the Executive Order identified above, including but not limited to, entry summaries filed without the required additional duties. If an entry summary is rejected, CBP will require a resubmission within two business days of the rejection, per existing policy. If the rejected entry summary is not resubmitted timely with payment, the importer of record may be subject to liquidated damages. 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 9903.01.20, then the 10% percent duty must be associated to 9903.01.20 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 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 patterns of non-compliance. CSMS # 63988468 identified the applicable HTS numbers associated to the additional duties: 9903.01.20: All imports of articles that are products of China and Hong Kong, other than products classifiable under headings 9903.01.21, 9903.01.22, and 9903.01.23, and other than products for personal use included in accompanied baggage of persons arriving in the United States - an additional ad valorem rate of duty of 10%. CSMS# 64018403 updated the reporting sequencing that includes 9903.01.20: HTS SEQUENCE: 1. Chapter 98 (if applicable) 2. Chapter 99 number(s) for additional duties (if applicable) 3.
