A parcel of three women’s suits arriving in the European Union attracts a customs duty of either EUR 3 or EUR 9, on the European Commission’s own worked example. The difference comes from what is in the box and from which customs declaration is filed for it.

A tariff classification is the code a customs authority assigns to a good under the Harmonised System, the nomenclature that sets which duty applies. The first six digits are the same worldwide. The European Union adds further digits separating material, origin and treatment, and how many digits a declaration carries decides how many entries a mixed parcel produces.

The European Union removed its duty relief for low-value consignments on 1 July 2026. Goods arriving in consignments valued at or below EUR 150 previously entered without customs duty and now carry a flat EUR 3 charge, set out in Council Regulation (EU) 2026/382 of 11 February 2026, with the operative rules in Commission Implementing Regulation (EU) 2026/1200 and Commission Delegated Regulation (EU) 2026/1022. The measure runs until 1 July 2028, after which normal tariff rates apply once the EU customs data hub is operational.

The threshold that has gone is a de minimis rule: a value below which a customs administration decides that collecting duty costs more than the duty is worth. The United States removed its own USD 800 de minimis exemption in 2025. The European version is a staged repeal, with the flat EUR 3 standing in until the data infrastructure to charge real rates exists.

The Council of the European Union put low-value packages entering the bloc at 4.6 billion in 2024, with 91 per cent of small shipments originating in China. Makis Keravnos, finance minister of Cyprus, said when the Council gave final approval in February 2026 that abolishing the exemption would support EU business and close avenues for unscrupulous sellers.

The Commission’s guidance for member states and economic operators states that the duty applies per declaration line irrespective of the quantity of articles in that line. A declaration line is one entry on a customs form covering goods that share a classification code. How finely those goods are coded depends on which declaration the seller files. An H7 declaration, the super-reduced dataset the European Union created for low-value consignments, groups goods at six digits. An H1 declaration, the full dataset used for ordinary commercial imports, splits them at ten, where the code separates material and origin.

The Commission’s suits example carries that through. Three women’s suits worth EUR 140 in total, one in artificial fibre, one in wool and one in another material, attract a single EUR 3 charge on an H7 declaration and three EUR 3 charges on an H1. A second example puts a consignment of bicycle parts at EUR 9, across three lines split by material and by origin.

Two provisions close the obvious workarounds. The guidance states that grouping items is not allowed where the EUR 3 applies, removing the simplification under Article 177 of the Union Customs Code that would otherwise let a declarant collapse several tariff lines into one. An anti-abuse clause lets customs recalculate the duty where successive sales have been bundled into one declaration, using indicators including separate labels on individual consignments and how often the same operator files.

Asian marketplace fulfilment runs on the pattern this penalises. A cross-border order typically combines several unrelated low-value items shipped together from a consolidation warehouse in Shenzhen or Ho Chi Minh City, because one parcel costs less to fly and to deliver than four. A basket of a phone case, socks, a hair clip and a charging cable falls under four classifications on either declaration route, so it attracts EUR 12. On a EUR 25 order, the duty approaches half the merchandise cost before freight, value-added tax or platform fees.

Each of the seller’s responses carries a cost. Splitting the basket into separate parcels does not help, because every parcel then carries its own EUR 3 and its own freight, and the anti-abuse clause is written to catch exactly that. Consolidating into fewer classifications means selling multiples of the same item, a different retail business from the long-tail catalogue these platforms run. Holding stock inside the European Union in a bonded warehouse moves the goods across the border in bulk and outside the low-value regime, but it requires working capital and a demand forecast the direct-ship model was designed to avoid.

The freight data already shows a response. WorldACD, the Netherlands-based air cargo market data company, recorded Hong Kong to Europe tonnages down 24 per cent year on year in the week to 19 July 2026, in a fifth consecutive weekly fall since the rule took effect, with the four-week average 18 per cent below the previous year. Mainland China to Europe was down 10 per cent over the same week. Combined, the two origins ran 11 per cent below the previous year across the four weeks to 19 July, against 5 per cent growth in the rest of the global market. Hong Kong carried the sharper fall because e-commerce made up a high share of its Europe traffic.

The declaration requirement will outlast the fee. The Import One-Stop Shop, the European Union’s simplified value-added tax scheme for distance sales, does not remove the customs declaration obligation, and the guidance is explicit that goods imported using it still carry the EUR 3. Sellers also cannot claim a preferential tariff rate through it. From 1 November 2026 product identifiers become mandatory, so a seller that has never held tariff classification data for its catalogue now needs it per stock-keeping unit.

A EUR 3 charge sounds like rounding. Applied per declaration line to a basket assembled by a shopper who has never thought about tariff headings, and multiplied by whichever declaration route the seller’s broker files, it becomes a tax on variety, and variety is the product the cross-border marketplace model sells.
