All shipments entering the United States must now undergo “Formal Entry”, meaning that significantly more paperwork is required to accompany each box in line with CBP regulations and IMO (International Maritime Organization) rules.
As a result of this, carriers now require consignees to provide a valid EIN or SSN to clear even the smallest package into the United States.
This ruling (CBP Directive 3550-079A) and the Form CBP 5106 have been in place since 2001. However, between 2020 and 2024, the Trade Facilitation and Trade Enforcement Act (TFTEA) raised the de minimis threshold from $200 to $800. This allowed carriers to expand their use of informal entry processing, using master importer accounts for blanket filings with CBP for thousands of shipments per day. As a result, they did not require Form 5106 or IRS information, nor did they need CBP Forms 3461 or 7501 (Formal Entry Filings).
This also excluded certain Partner Government Agency (PGA) declarations under the simplified method.
However, in April and May 2025, CBP began phasing out informal entry benefits entirely.
On April 5, the threshold for informal entry was reduced from $2,500 to $800, meaning a much larger number of shipments now require formal entry paperwork.
Then on May 2, the de minimis exemption was removed for goods originating from China, meaning that even low-value packages from these regions must now go through full customs clearance and are subject to duties.
At the same time, CBP began enforcing the requirement for all consignees to provide a valid IRS number, regardless of the shipment’s value.
All of this followed on from Biden ruling In September 2024 where the US government announced changes to the de minimis rules, shifting from the previous $800 per parcel limit to an $800 total per person per day. This means that instead of each individual shipment being duty-free under $800, all shipments to the same person on the same day are now counted together and anything over that total must go through full customs clearance.
