Summary: One EU-level data layer replaces 27 national customs systems, platforms become deemed importers, and the declaration gives way to a continuous data feed. Here is the timeline and what it changes.

Key dates:
- 17 May 2023: Commission proposes the customs reform package
- 2028: Data Hub opens for e-commerce; platforms act as deemed importers
- 1 Jul 2028: Transitional flat duty on low-value imports expires
- 2031: Data Hub opens to all other traders, voluntarily
- 2034: Use of the Data Hub becomes mandatory for all traders

**Correction, 14 August 2026.** This piece originally gave the Data Hub's later milestones as 2032 and 1 January 2038, the dates in the Commission's 2023 proposal. The text agreed by Council and Parliament on 26 March 2026 sets them at 2031 and 2034. The dates below have been corrected and [the agreement is covered here](/customs-reform-agreed-handling-fee-data-hub-dates/).

Every rule described elsewhere on this site — the [€3 flat duty](/eu-de-minimis-ends-3-euro-flat-duty/),
the expanded parcel dataset, the shifted customs debtor — is a bridge to one thing:
the EU Customs Data Hub. Understand the destination and the interim measures stop
looking arbitrary.

## What it replaces

Today an import declaration is filed into a national system. Twenty-seven member
states, twenty-seven implementations, twenty-seven sets of local practice sitting on
top of the same Union Customs Code. A seller shipping to five markets deals with
five interfaces and five customs administrations.

The Data Hub inverts that. It is a single EU-level data layer into which traders
supply information about goods, supply chains and parties — once — with the national
administrations and a new EU Customs Authority drawing on the same pool. The design
intent is a shift from **declaration-based** customs to **data-driven** customs:
instead of a document filed per shipment at the border, a continuous data
relationship with authorities that can be risk-scored before goods move.

## The timeline

The reform package was proposed in May 2023. The sequencing that matters now:

| When | What |
|---|---|
| 2026 | Duty relief removed; flat charge and expanded parcel data as interim measures |
| 2028 | Data Hub opens for e-commerce consignments; platforms act as deemed importers |
| 1 Jul 2028 | Transitional flat duty expires; normal tariff treatment intended |
| 2031 | Data Hub opens to all other traders, on a voluntary basis |
| 2034 | Data Hub use becomes mandatory for all traders |

Dates beyond 2028 depend on legislative texts still moving and on delivery of a very
large IT programme. The 2028 e-commerce milestone is the one to plan against; 2031
and 2034 are direction, not commitment.

## Deemed importer: the structural change

The reform makes platforms and distance sellers the **deemed importer** of goods
sold to EU consumers. They carry the customs formalities, the duty and VAT payments,
and responsibility for the goods complying with EU product rules. The consumer stops
being an accidental importer of record.

For a marketplace, that converts a listing relationship into a customs liability. The
predictable consequence is that marketplaces will demand from sellers exactly what
they will owe to customs: HS codes, country of origin, value breakdown, compliance
documentation — at item level, before the listing goes live rather than after the
parcel is stopped. Sellers will feel the 2028 reform as marketplace onboarding rules
in 2027.

## What to build now

Nothing here rewards waiting for the final legal text.

- **Item-level product data.** HS code, country of origin, intrinsic value, materials
  and compliance references as first-class SKU fields, owned by someone, with a review
  cycle. This is the input every 2026–2028 requirement consumes.
- **One data model, many destinations.** The Data Hub's premise is supply once. Systems
  that keep customs data per-carrier or per-marketplace will need to be unpicked.
- **Landed cost as a live calculation.** Duty on every parcel plus per-market EPR fees
  means checkout price and margin depend on destination. Hard-coded shipping tables
  will not survive.
- **Know who your importer of record is per flow.** After 2028 the answer differs
  between marketplace sales, own-site DDP sales and B2B shipments. Each needs a
  documented position now.

The through-line of EU commerce policy since 2021 is consistent: harmonise the
rulebook centrally, keep collection national where money is involved, and push
liability from the consumer onto whoever is closest to the sale. The
[PPWR obligations that started on 12 August 2026](/ppwr-eu-2025-40-applies-today/)
follow the same logic in a different domain. The Data Hub is that principle applied
to the border itself.
