It carries the official CBP guidance brokers and importers must follow for the topic — "UPDATED GUIDANCE: Section 301 China Conforming Amendment (Corrected)".

The updated date for the functionality for the acceptance of the amended product exclusions in the Automated Commercial Environment (ACE) is 7 a.m. Eastern Daylight Time, February 8, 2022. BACKGROUND These amendments were published by the U.S. Trade Representative (USTR) on December 7, 2021 in 86 FR 69350 , technical amendments to U.S. notes 20(iii)(37), 20(qqq)(16) and 20(sss)(iii)(13) to subchapter III of chapter 99 of the Harmonized Tariff Schedule of the United States (HTSUS) number 3401.30.5000, replacing it with HTSUS number 3401.11.5000 effective November 30, 2020. POST SUMMARY CORRECTIONS As noted in CSMS # 50516041 , importers who entered nonwoven wipes under HTSUS number 3401.30.5000 and claimed the exclusion from additional Section 301 duties, as of November 20, 2020, should file Post Summary Corrections (PSCs) to correct their entries and properly pay Section 301 duties. Importers who entered nonwoven wipes under HTSUS number 3401.11.5000 and paid Section 301 duties, as of November 30, 2020, should file PSCs to obtain refunds on duties paid. To request a refund of Section 301 duties paid on previous imports of products granted duty exclusions by the USTR, importers may file a PSC if within the PSC filing timeframe. If the entry is beyond the PSC filing timeframe, importers may protest the liquidation if within the protest filing timeframe. The latest guidance on the process for submitting retroactive claims for product exclusions to Customs and Border Protection (CBP) is found in CSMS# 42566154 . Importers will have an additional 60 days from the publication date of this message to file PSCs. If importers do not correct their entries, Center personnel may change the impacted entries and rate advance them.

What is CSMS 50980729?

CSMS 50980729 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "UPDATED GUIDANCE: Section 301 China Conforming Amendment (Corrected)". 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 50980729 published?

CBP published CSMS 50980729 on February 9, 2022. 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.
