CBP's paired June 24 rules ended the $800 de minimis exemption and established a postal informal entry test. Entry Type 13 is scheduled for ACE certification on July 24 and production on September 22, with additional draft query and error guides now posted. Why it matters: Importers, brokers, carriers, and e-commerce operators now have a concrete implementation window for postal Entry Type 13 data and EDI changes. The test is limited to eligible mail shipments valued at $2,500 or less; higher-value, quota, and AD/CVD shipments require formal entry, and other tariff or agency restrictions can also make the postal informal path unavailable. https://tariffnotices.com/signal/cbp-post-summary-corrections-aug-2026/ https://tariffnotices.com/signal/cbp-post-summary-corrections-aug-2026/ Sat, 11 Jul 2026 09:46:33 GMT Customs Verified brief. CBP modified its Post-Summary Correction test: increases in estimated duties, taxes, and fees must move to electronic ACH payment, later PSCs are blocked until prior increases are fully processed, and certain suspended entries may be corrected beyond the normal 300-day window. Why it matters: Importers and brokers using ACE Post-Summary Corrections need payment and filing workflows ready by August 5, 2026. Check or cash will no longer be accepted for PSC increases, and incomplete payment can block a subsequent correction.
