• Per 85 FR 72748, U.S. note 20(yy)(75) under product exclusion round 9903.88.46 is amended by deleting “(described in statistical reporting number 8427.90.0090)” and inserting “(described in statistical reporting number 8427.90.0000 prior to July 1, 2019; described in statistical reporting number 8427.90.0090 effective July 1, 2019)” in lieu thereof.
• Importers shall not submit the corresponding Chapter 99 HTS number for the Section 301 duties when HTS 9903.88.46 is submitted.

Additional Information

Imports which have been granted a product exclusion from the Section 301 measures, and which are not subject to the Section 301 duties, are not covered by the Foreign Trade Zone (FTZ) provisions of the Section 301 Federal Register notices, but instead are subject to the FTZ provisions in 19 CFR part 146.

To request a refund of Section 301 duties paid on previous imports of products granted duty exclusions by the USTR, importers may file a Post Summary Correction (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 CBP is found in CSMS 42566154.

In situations where an importer has requested a product exclusion and the request is pending with the USTR, importers or their licensed representative may submit a request to extend the liquidation of impacted unliquidated entry summaries to CBP.

Reminder: importers, brokers, and/or filers should refer to CSMS 39587858 (Entry Summary Order of Reporting for Multiple HTS when 98 or 99 HTS are required) for guidance when filing an entry summary in which a heading or subheading in Chapter 99 is claimed on imported merchandise.

For ease of reference, a summary of Section 301 duties and product exclusion notifications is attached.

Questions from the importing community concerning ACE entry rejections involving product exclusions should be referred to their CBP Client Representative.
