The EU is introducing major customs and IOSS‑related changes from 1 July 2026 that will hit anyone shipping low‑value B2C parcels into the EU, especially e‑commerce brands using IOSS.

Key 2026 EU changes affecting IOSS

• End of the 150 EUR duty‑free threshold for imports. From 1 July 2026, low‑value parcels up to 150 EUR will no longer be exempt from customs duties; all such imports become dutiable.
• New flat 3 EUR customs duty on small parcels. For shipments up to 150 EUR sold to EU consumers, a fixed 3 EUR customs duty per consignment or declaration line will apply as an interim measure.
• 3 EUR duty also applies to IOSS parcels. Goods sold under the IOSS scheme up to 150 EUR will be charged this flat 3 EUR customs duty in addition to import VAT.
• Future EU‑wide handling fee. An additional EU‑wide “customs handling fee” for low‑value e‑commerce imports is expected from late 2026, on top of the 3 EUR duty; some Member States may add their own national handling fees earlier.

What IOSS is – and what doesn’t change

• IOSS (Import One‑Stop Shop) is the EU’s simplified VAT regime for distance sales of imported goods up to 150 EUR, introduced in 2021.
• It lets sellers or marketplaces collect VAT at checkout and remit it via a single monthly return, instead of the customer paying VAT on delivery.
• VAT rules remain the same in 2026: the EU already removed the VAT de minimis in 2021, so all commercial imports are subject to VAT regardless of value; the 2026 reform mainly adds customs duty and fees.

How the 3 EUR duty interacts with IOSS

Sources describe two “lanes” for low‑value B2C imports after July 2026.

• IOSS lane (recommended):
  • Seller collects EU VAT and the 3 EUR customs duty at checkout.
  • Data is pre‑cleared, so parcels should go through customs faster with fewer surprises for customers at the door.
• Non‑IOSS lane:
  • Parcels face more manual processing and are still subject to the 3 EUR duty, plus any carrier or postal handling fees charged to the recipient.
  • Some Member States already apply national handling charges (e.g. Belgium, France, Italy, Netherlands, Romania), and the EU‑wide fee will add an extra layer later in 2026.

Timeline of EU customs and IOSS‑related reforms

• 1 July 2026 – key go‑live date:
  • Abolition of the 150 EUR customs duty exemption for small parcels.
  • Introduction of the 3 EUR flat customs duty on shipments up to 150 EUR, including those using IOSS.
• End of 2026 – EU handling fee:
  • A Union‑wide handling fee per line/parcel for e‑commerce imports is planned around November 2026, with national handling fees allowed in parallel.
• Toward 2028 – broader customs/VAT reform:
  • EU plans include a new “duty bucket” system with a small set of standard duty rates and the launch of an EU Customs Data Hub.
  • The Commission also aims to abolish the 150 EUR threshold for IOSS itself and further strengthen IOSS under its “VAT in the Digital Age” initiative.

Impact on e‑commerce sellers and 3PLs

• All low‑value imports become more expensive to land. Even a 3 EUR duty is significant for ultra‑low‑value SKUs, and you may need to rework pricing, free‑shipping thresholds, or product bundles.
• Customer experience for non‑IOSS shipments deteriorates. Parcels risk delays, extra handling fees at delivery, and unhappy customers facing unexpected charges.
• IOSS becomes strategically more important. Although the new duty applies to IOSS parcels too, running everything through IOSS reduces surprises and simplifies VAT/duty collection via a single workflow.
• Data and product ID requirements increase. From 2026, shippers must provide additional product identifiers and more granular data on import declarations for low‑value goods.

Practical steps to prepare for 2026 IOSS changes

• Register or optimise your IOSS setup. Non‑EU sellers should consider IOSS registration (direct or via intermediaries) well before July 2026 to avoid last‑minute disruption.
• Model landed‑cost scenarios with the 3 EUR duty. Recalculate margins and retail pricing assuming duty is charged on every B2C parcel under 150 EUR, and incorporate any expected EU/national handling fees.
• Decide who pays – you or the customer. Clarify whether you will absorb the duty/fees or pass them on at checkout; inconsistent treatment will confuse customers and hurt conversion.
• Upgrade customs data quality. Ensure product catalogues have clean HS codes, product identifiers and values so declarations meet the new data standards coming with the customs reform.
• Align with 3PLs and carriers. Work with fulfilment partners to be sure they can support IOSS numbers, apply the correct duty, and handle the increased data requirements from mid‑2026 onwards.
