Changelog
Every change to the dataset behind this site, with the source that prompted it. A weekly job watches each source page for edits; when one moves, it lands here. This page is how you check whether to trust the rest of the site.

Site launched with the post-24-July rule set
First publication. The dataset was built from primary sources on 1 August 2026 and reflects three changes that most other guidance has not caught up with: IEEPA reciprocal tariffs were terminated on 20 February 2026, the 10% Section 122 surcharge expired on 24 July 2026, and Section 301 forced-labour tariffs of 10%–12.5% took effect the same day across 60 economies. De minimis is suspended for every mode.

FY2027 customs user fees loaded ahead of time
CBP published the FY2027 fee adjustment on 31 July 2026. Both schedules are in the dataset with a changeover date, so estimates dated on or after 1 October 2026 already use the new figures — the informal entry fee rises from $2.69 to $2.77 and the express consignment fee from $1.34 to $1.38.

Correction: FY2027 fees did not show until today
Our 1 August entry said the FY2027 fees would apply automatically from 1 October. On the pages and in the calculator they did not. From 1 to 9 October this site kept quoting FY2026 fees: $2.69 instead of $2.77 for the informal entry fee, $1.34 instead of $1.38 for express consignment, and a $33.58 instead of $34.58 minimum merchandise processing fee on formal entries. On a typical parcel that is 12 cents, but a site whose whole point is being current should not be off by any amount. FY2027 is now the live schedule everywhere, and the calculator now picks the fee schedule by today's date rather than the date we last swept the data.

Correction: the 22 October postal deadline is much wider than we said
We described 22 October 2026 as the end of a narrow postal exception that mattered mainly for FDA-, USDA- and FCC-regulated goods. Re-reading the rule, that understated it. From 22 October, the postal informal entry process is limited to goods classifiable only in HTSUS chapters 1–97, so any mail shipment subject to an additional chapter 99 duty needs formal entry instead. The 2026 Section 301 forced-labour duties are chapter 99 headings (9903.05.20–9903.05.84), and they apply to every origin on this site unless a product is on the annex exemption list. The one alternative CBP offers is the voluntary Entry Type 13 electronic mail entry test, scheduled to begin on 22 September 2026, which accepts these goods. Goods under antidumping or countervailing duty orders or quotas cannot use it.

9 October sweep: every source re-checked, no rate changed
We re-checked all 42 dated rows against their sources today. The 20 MFN rate ranges match the live USITC tariff schedule exactly, and no duty rate on this site changed. New since the last sweep: CBP proposed a "Low-Value Shipments" rule on 8 October that would make Entry Type 13 a permanent mail entry type, but it is only a proposal (comments close 7 December 2026) and changes nothing yet. On 7 October USTR confirmed that the 2018 China Section 301 action did not terminate and continues while its four-year review runs. The China product exclusions now have a primary source, which runs them through 9 November 2026. In September, Canadian vehicles, dairy and alcohol came under new import restrictions. None of those are in categories this site covers.

New: what the 22 October postal deadline means, and the calculator now knows the date
A new page, 22 October 2026: the end of cheap postal entry, sets out what the rule says, the Entry Type 13 alternative, and what to do before the date. The calculator follows the rule too. For postal estimates dated 22 October or later, it shows the route as a formal mail entry or the Entry Type 13 test instead of postal informal entry, for every origin on this site.

Fix: postal parcels over $2,500 no longer show a merchandise processing fee
Above $2,500 the calculator charged postal parcels the formal-entry merchandise processing fee, with a $34.58 minimum. Merchandise imported by mail is exempt from that fee whether it is entered formally or informally, under 19 CFR 24.23(c)(1)(v). The one exception is an Inbound EMS item, such as international Speed Post, that is formally entered, and the fee note now says so.
Get told when these rules change
US import rules for small sellers changed three times in 2026 — February, June and July. When the next one lands, you get one plain-English email. No schedule, no filler; some months there is nothing to send.
