2026 has been the most disruptive year for cross-border parcel delivery in at least a decade. A US Supreme Court ruling wiped out one tariff regime and a replacement appeared within hours. The EU abolished its low-value duty relief. ICS2 finished its rollout. Three separate EU compliance regimes started applying. This is the dated version, so you can find what hits you and when.

The United States: de minimis ends, permanently
The $800 duty-free de minimis exemption under 19 U.S.C. 1321(a)(2)(C) is gone, for all origins and all modes of transport.
The sequence began before 2026. Executive Order 14256 ended de minimis for China and Hong Kong on 2 May 2025, EO 14324 extended the suspension globally from 29 August 2025, and EO 14388 kept it in place after the Supreme Court curtailed the use of IEEPA.
The important 2026 development is that the suspension no longer depends on any of those orders. On 24 June 2026 CBP published two interim final rules:
- 91 FR 37789, covering all modes other than post, effective 24 June 2026.
- 91 FR 37801, covering mail, effective 24 July 2026.
CBP grounded both in its own authority under 19 U.S.C. 1321(b), and stated that it would maintain the suspension even if the underlying executive orders were withdrawn. Any planning scenario in which a court ruling or a policy change restores de minimis is now considerably weaker. The suspension has moved from executive action into regulation.
The new postal informal entry process
The mail rule creates a postal informal entry process for mail shipments valued at $2,500 or less. The mechanics matter because they exclude a lot of senders who previously never had to think about entry filing:
- Only owners, purchasers or licensed customs brokers may file.
- Filers submit a monthly International Mail Duty Worksheet using 10-digit HTSUS lines.
- Payment is by ACH debit, due by the 7th of the following month.
- Filers must hold a continuous bond in ACE eBond.
CBP estimates over $100m a year in additional duty from the postal process alone. Separately, the transitional postal flat "specific duty" option ended, and from 28 February 2026 all covered mail must use ad valorem duty. That removes the last simplified route for postal shipments into the US.
Context on volumes. UPU-measured traffic to the US fell 81% on 29 August 2025 against the prior Friday, with 88 postal operators suspending some or all US service. The UPU responded with a landed-cost API on 5 September 2025 and a full DDP solution inside its Customs Declarations System, used by 176 operators, from October 2025. Postal capacity into the US now runs on duty-paid infrastructure rather than on an exemption.
Comment periods on both rules closed on 24 and 25 July 2026. Final rules had not been issued as of early August 2026.
The United States: tariff whiplash from IEEPA to Section 301
The single most consequential day of the year was 20 February 2026, when the Supreme Court held 6-3 in Learning Resources, Inc. v. Trump that IEEPA does not authorise tariffs. That invalidated the fentanyl and reciprocal tariffs. CBP stopped collecting IEEPA duties at the end of 23 February. Refund estimates conflict and are best cited as a range of roughly $166bn to $175bn.
Within hours, the administration imposed a 10% global tariff under Section 122 of the Trade Act of 1974, effective 24 February 2026. Section 122 carries a 150-day statutory cap, so the tariff expired by operation of law at 12:01am on 24 July 2026. It also faced litigation: the Court of International Trade struck it down on 7 May 2026, though relief was party-specific to three importer plaintiffs. The government appealed on 8 May and the Federal Circuit granted a temporary stay on 12 May.
At the moment Section 122 lapsed, USTR Section 301 "forced labour" tariffs took effect, following final action on 23 July 2026. The structure is a two-tier 10% or 12.5% covering imports from 60 economies, together roughly 99.4% of US imports.
How the Section 301 tiers apply
| Group | Treatment |
|---|---|
| EU, Taiwan | Topped up to a combined 10% with MFN |
| Japan, Korea, Switzerland | Topped up to 12.5% |
| Canada, Mexico, India, Indonesia, Bangladesh, Cambodia, Malaysia, Pakistan, Sri Lanka, UK, CAFTA-DR countries | 10% additive on top of existing rates |
| Vietnam, Brazil, Thailand, Türkiye, Philippines, Singapore | 12.5% additive |
| China | 12.5% additive, stacking with the existing 25% to reach 37.5% aggregate Section 301, plus MFN |
Exemptions cover goods already under Section 232 (steel, aluminium, copper, autos and parts, wood, semiconductors), civil aircraft, pharmaceutical inputs, and goods qualifying under USMCA, CAFTA-DR for textiles and apparel, and the Jordan FTA.
The strategic point. Unlike IEEPA and Section 122, Section 301 has no statutory rate ceiling and no expiry date. The two previous regimes had a built-in end. This one does not. That makes FTA-qualifying origin the single largest landed-cost lever available to a US importer, worth a swing of 10 to 12.5 percentage points. Origin documentation is now a pricing input, not paperwork.
One further item is pending. Section 338 tariffs of 50% on Canadian goods are scheduled for 19 August 2026, and CBP guidance does not yet clarify whether they stack with Section 301.
The European Union: the €3 duty and the customs reform deal
The EU spent 2026 doing in law what the US did by executive action, on a longer timetable.
Council Regulation (EU) 2026/382 was adopted on 11 February 2026, following political agreement on 13 November 2025. From 1 July 2026, the €150 customs duty relief was abolished, and a temporary €3 flat customs duty applies, running until 1 July 2028.
The mechanic that trips people up: the €3 is charged per distinct tariff classification in a consignment, not per unit and not per parcel. Five T-shirts in one parcel is €3. Three T-shirts plus a watch is €6. It applies to distance sales in consignments up to €150 regardless of VAT scheme, and liability sits with the declarant, not the consumer. The Commission's justification is scale: 5.9 billion low-value items shipped direct to EU consumers in 2025, and over 60% non-compliance in targeted EU-27 inspections that year.
Two dates follow from it. Product Identifiers are voluntary from 1 July 2026 and mandatory from 1 November 2026. From 1 October 2026, the Commission runs monthly monitoring for IOSS diversion and avoidance, and may propose widening the scope.
The reform that lands later
On 26 March 2026, the Council and Parliament reached provisional agreement on the full customs reform, a new Union Customs Code. It applies 12 months after publication in the Official Journal, but the operational dates run further out:
- The EU Customs Authority is created, with its seat chosen on 25 March 2026 as Lille, France.
- The EU Customs Data Hub becomes operational for e-commerce goods on 1 July 2028, with phased rollout to all goods movements by 1 March 2034.
- Platforms and distance sellers become the deemed importer, responsible for formalities and payments rather than the consumer.
- A "trust and check" trader status is introduced, and financial penalties are added for systematically non-compliant e-commerce operators.
The same agreement confirmed an EU-wide handling fee on small distance-sale consignments, separate from the €3 duty. The amount is to be set by delegated act and applied by Member States no later than 1 November 2026. As of August 2026, the amount is not fixed, and the Commission's June FAQ says both the amount and the autumn application date remain to be determined. In the meantime, national fees create a patchwork: Romania's 25 RON, roughly €5, has been live since 1 January 2026, Italy set €2 from the same date with conflicting reports about a pause, France included a measure in its 2026 Finance Act, and the Netherlands and Belgium dropped their proposals.
Border and compliance layers that landed quietly
Three EU regimes started applying in 2026 that have nothing to do with tariffs and everything to do with whether your parcels move.
ICS2 is complete. Release 1 covered postal and express air pre-loading from March 2021. Release 2 brought full ENS for air in March 2023. Release 3 covered maritime and inland waterway at house level from 1 April 2025, then road and rail from 3 February 2026, with Croatia, Latvia, Poland, Romania and Slovakia completing road rollout on 1 June 2026. From 1 June 2026, every consignment entering the EU by any mode needs a valid Entry Summary Declaration. An updated stop-words list took force on 3 August 2026: vague goods descriptions now get the ENS rejected or trigger referrals. "Gift", "sample" and "parts" are the kind of description that stops working.
The withdrawal button. Directive (EU) 2023/2673 applies from 19 June 2026. Any trader selling online to EU consumers, wherever it is established, must provide a clearly visible and continuously available electronic withdrawal function throughout the 14-day withdrawal period, with a separate confirmation step and an acknowledgement on a durable medium. It is a storefront change rather than a logistics one, and easy to miss because it sits with the web team. Do not confuse it with the Digital Fairness Act, which remains a proposal.
PPWR. Regulation (EU) 2025/40 starts applying on 12 August 2026, bringing packaging minimisation, substance restrictions, a declaration of conformity and EPR registration. Several widely quoted empty-space figures could not be confirmed at primary source, so treat any specific percentage in trade press with caution and work from the regulation itself.
Platform enforcement and the UK's acceleration
Enforcement against large marketplaces moved from investigation to penalty. On 28 May 2026 the European Commission published its decision fining Temu €200m for failing to assess the systemic risk of illegal products on its platform, the largest DSA fine to date. Temu's action plan is due on 28 August 2026. Formal DSA proceedings were opened against Shein in February 2026.
The read-across for merchants is simple. Marketplaces under DSA pressure tighten seller requirements, listing checks and product documentation, and they do it faster than regulators do. If you sell through a platform under investigation, expect the compliance burden to arrive as a marketplace policy change rather than as a regulation.
In the UK, the government announced on 23 June 2026 that it would accelerate by six months the abolition of customs duty relief on low-value imports of £135 or under, now to be implemented by October 2028 at the latest. There was no 2026 change to the £135 import VAT threshold. The UK is moving in the same direction as the EU and the US, just later.
Conclusion: what is still unresolved
Five things are genuinely open as of early August 2026, and each one is capable of changing a landed-cost model.
- The EU handling fee amount. Confirmed in principle, to be set by delegated act, to be applied no later than 1 November 2026. The figure is not public. Model it as a variable.
- CBP final rules. Comment periods on both interim final rules closed on 24 and 25 July 2026. Final rules have not been issued. The postal informal entry mechanics could still be adjusted.
- Section 338 on Canada. Scheduled for 19 August 2026 at 50%, with no CBP guidance yet on whether it stacks with Section 301. For anyone with Canadian-origin goods this is the nearest cliff edge.
- Section 301 litigation risk. The tariffs are in force and have no expiry or rate ceiling, but the pattern of 2026 is that every tariff regime gets challenged. The Federal Circuit is still handling the Section 122 appeal after its 12 May stay.
- Temu's DSA action plan. Due 28 August 2026. The response will set expectations for how the Commission handles the open Shein proceedings.
The lesson from 2026 is not about any single rule. It is that landed cost and transit time now change several times a year, on dates set by courts and delegated acts rather than by carriers. The teams coping best treat duty rates, fees and thresholds as configuration rather than assumptions, and keep consistent tracking and exception data across every carrier and 3PL they use, so that when a rule changes they can see immediately which shipments are affected. That second half is the problem Ship24 works on, and it is the one that carries into 2027.
