CBP Delays Postal De Minimis Compliance to January 20, 2027: What Sellers Should Do
CBP pushed the formal-entry deadline for certain mail shipments from October 22 to January 20, 2027. The de minimis suspension itself did not change.

U.S. Customs and Border Protection (CBP) moved the compliance date for formal entry of certain mail shipments from October 22, 2026 to January 20, 2027. The suspension of the de minimis exemption did not change. Sellers shipping low-value parcels through the mail still owe duties, and should use the extra weeks to prepare.
This guide is for cross-border ecommerce sellers, importers of record and brokers who move small parcels into the United States by mail. It explains what the delay changes, what it leaves alone, and how to use the time before January. Laneage covers trade policy for shippers, and this rule sits in the part of the rulebook that is easy to misread because two deadlines now overlap.
What Did CBP Change on October 22, 2026?
CBP published a final rule, scheduled for the Federal Register on October 22, 2026, that extends one compliance date. The agency said it believes the public will benefit from more time to prepare. The new date applies to 19 CFR 145.12(a)(2)(v) and (vi), according to the Federal Register public inspection copy.
Those provisions cover mail merchandise that faces partner government agency (PGA) requirements, duties under Chapter 98 or 99 of the Harmonized Tariff Schedule, or duty-free claims under Chapter 98 or a free trade agreement. Such goods are not eligible for the new postal informal entry process. They must go through formal entry instead.
The original date for that requirement was October 22. It is now January 20, 2027, a delay of 90 days.
Is the De Minimis Exemption Back for Mail?
No. The delay changes one compliance date and nothing else. On June 24, 2026, CBP published an interim final rule that indefinitely suspended the $800 de minimis exemption for merchandise arriving through the international postal network. That suspension took effect on June 24, and the rest of the rule took effect July 24, as the CBP notice states.
The suspension follows an executive order from July 30, 2025 that ended duty-free de minimis treatment for all countries, which a later order continued in February 2026. A separate law, Public Law 119-21, also eliminates the exemption by statute on July 1, 2027, according to Thompson Hine's summary of the rules.
The result is simple. A $40 parcel from overseas does not enter duty-free anymore. We explained the earlier rules in our guide to de minimis changes and what they mean for importers.
How Does Postal Informal Entry Work?
Postal informal entry is the process CBP built for mail that used to qualify for de minimis. It applies to mail shipments valued at $2,500 or less. Instead of passing through unseen, each shipment is declared with real data.
According to Thomson Reuters' regulatory summary, each entry needs:
- A description of the merchandise.
- The country of origin.
- A 10-digit Harmonized Tariff Schedule (HTS) code.
- The value and the duty rate.
- The total duty owed.
- The carrier, tracking number, arrival port and arrival date.
The filer sends that data to CBP in a spreadsheet by the 7th day of the month after arrival. The filer must also hold a single transaction bond or a continuous bond that covers mail entries, per the Thomson Reuters analysis.
A bond is a financial guarantee that duties will be paid. A single transaction bond covers one shipment, while a continuous bond covers entries over a year. For a seller who ships a few parcels a week, a continuous bond is usually cleaner than buying one bond per parcel.
Who Is Allowed to File?
Only the owner, the purchaser, or a licensed customs broker designated by the owner or purchaser can file. That restriction matters for platforms and consolidators. A non-broker party that used to file International Mail Duty Worksheets can continue only if it is also the owner or purchaser of the goods.
A marketplace seller who sells to a U.S. consumer is usually the owner until delivery. That makes the seller, not the postal operator, the party that has to arrange compliance or hire a broker. Many small sellers have not thought about this, because the old exemption made customs filing invisible.
Which Shipments Get the Extra Time?
Only the narrow group that is not eligible for informal entry gets the delay. That group is mail that triggers PGA data requirements, Chapter 98 or 99 duties, or Chapter 98 or free trade agreement duty-free claims.
In plain terms, think of items regulated by another agency, such as the Food and Drug Administration or the Consumer Product Safety Commission. Cosmetics, supplements, electronics with radio parts and children's products can all fall into that group. These items need formal entry, which costs more time and money than informal entry.
The delay also touches goods covered by a trade deal. A seller claiming duty-free treatment under a free trade agreement must use formal entry once the new date arrives. Sellers who skip the paperwork pay full duty instead.
Policy shifts like this tend to come in clusters. Duty exposure also depends on the tariff rate for each product, which is why the US-China tariff truce running to January 10, 2027 matters for any seller whose parcels start in China.
What Should Cross-Border Sellers Do With the Extra Time?
The delay is a grace period, not a pause button. Holiday volume will take most of the weeks between now and January 20, so preparation has to start now. We recommend this sequence:
- List every product you mail into the U.S., with its country of origin and value.
- Assign a 10-digit HTS code to each product, and keep a record of the reasoning.
- Flag products that touch PGA rules, Chapter 98 or 99 duties, or FTA claims.
- Choose a licensed customs broker or confirm you can file as the owner.
- Buy a continuous bond, or price single transaction bonds for low volume.
- Update customer pricing so duties are collected at checkout, not absorbed.
Classification is where sellers lose the most time. A wrong code changes the duty rate, and a bad description invites questions. Our walkthrough on classifying goods under HTS codes covers the logic.
Pricing matters too. Sellers who absorbed duties during the holiday rush often discover in January that their margin was thinner than they thought. A delivered-duty-paid price that includes duty is easier to defend than a surprise bill to the customer.
What This Means for Different Types of Sellers
The impact depends on what you ship and how. A seller of plain apparel under $2,500 per parcel falls into postal informal entry and gets no extra time, because the new date does not touch that group. The work there is classification, bonds and data, and it applies now.
A seller of cosmetics or supplements sits in the delayed group. That seller has until January 20, 2027 before formal entry becomes mandatory, but the product still needs correct agency paperwork. A broker can tell you in one call whether an item needs a Food and Drug Administration filing.
A marketplace operator that fulfills for many sellers has the broadest task. It has to decide whether it acts as filer, whether sellers appoint a broker, and how duty costs are shown at checkout. Those choices take weeks to build, so they should be settled before peak orders arrive.
What Could Go Wrong?
Three risks stand out. The first is assuming the delay applies to all mail. It does not, and a seller who misreads it may miss an entry requirement on shipments that never got relief. The second is relying on a postal operator to file. The rule says the owner, purchaser or broker files, so the legal duty stays with the seller.
The third risk is a bond gap. A filer without the required bond cannot complete the entry, and goods can sit while the paperwork catches up. Sellers should confirm bond coverage before the first January shipment, not after.
There is also a fair counterpoint. CBP could extend the date again, and the January deadline could shift. Sellers should not plan around that hope. A delay published the very day the old deadline arrived is a reminder that these rules can move in both directions.
Conclusion
CBP's delay gives certain mail shipments until January 20, 2027 to meet formal entry rules, but it leaves the de minimis suspension fully intact. Laneage's editors read the Federal Register notice and two legal summaries and found the same split: relief for a narrow group, no relief for the rule itself.
Your next step is a product list with HTS codes, owners and bond status. Finish that list before December, and the January date becomes a deadline you meet instead of one you scramble for.
