US Customs has amended the Automated Commercial Environment’s Frequently Asked Questions document to include discussions about Post Summary Corrections (PSCs).
As discussed in our blog post of May 9, PSC functionality became available in June for entry ACE type 01 and 03 summaries filed in ACE. One of the notable benefits of this new functionality is an importer’s ability to file electronic PSCs in ACE up to 270 days after the date of entry (currently 10 days if filing in ACS rather than ACE).
The new FAQs address issues such as who may file PSCs (either the same filer as the original entry summary filer or a different filer), and the number of PSCs that may be filed for one entry summary (unlimited).
The updated FAQ document is available here.
