The evidence behind the proposed dock-dues extension for the French outermost regions is set out in a Commission staff working document, SWD(2026) 661
Europa, accompanying the proposals to extend the scheme to 31 December 2030Europa and add twenty-two product codesEuropa. The document is analytical support, not law: it accompanies two proposals — a Council Regulation (COM(2026) 661)Europa and a Council Decision amending Decision (EU) 2021/991 (COM(2026) 662)Europa — which the Council must still adoptEuropa. This story covers the dock-dues analysis.
The document records why the scheme exists. Dock dues (octroi de mer) are a consumption taxEuropa levied in Guadeloupe, French Guiana, Martinique, Mayotte and RéunionEuropa on imported goods and on locally produced goods at the point of saleEuropaEuropa. Under Decision (EU) 2021/991, in force from 1 January 2022 to 31 December 2027Europa, France may exempt locally produced goods listed in Annex I (Lists A and B) from the dues or reduce their rateEuropa, with tax differentials of up to 20 percentage points (List A)Europa or 30 percentage points (List B) against imported equivalentsEuropa. A 2025 French evaluation found companies in the regions face production costs 11.3% above mainland counterpartsEuropa — 7.4% after direct aidEuropa, and 1.2% on average once the dock-dues differential is factored inEuropa — with the scheme mainly benefiting relatively dynamic sectors whose growth mostly exceeded the regional average.
The document identifies the legal problem the proposal fixes: the Annex I codes were fixed in 2021Europa, the Combined Nomenclature changes every yearEuropa, and the Decision allows no update or addition during its application periodEuropa. Regional authorities must apply rates on the basis of the latest codesEuropa, so obsolete entries create legal uncertainty over which goods still qualifyEuropa. The remedy is a delegated power for the Commission to update Lists A and B each year once the nomenclature is updatedEuropa, alongside the addition of new codesEuropa and the extension to 2030Europa.
On the twenty-two new codes, the document gives the sector logic territory by territory. In Guadeloupe, plastics support insulation production and diversificationEuropa where no differential currently appliesEuropa. In Martinique, meat-processing derivatives support diversification of meat productionEuropa, while forest-industry construction inputs, fibreboard, float glass and laminated safety glass serve the strategic construction sectorEuropa. In French Guiana, rice supports food securityEuropa — local rice covered 90% of domestic needs until 2007Europa and has since nearly vanishedEuropa — alongside construction boards including mycelial panels from locally grown fungal strainsEuropaEuropa, corrugated packagingEuropa, and adhesives and fungicides from local raw materialsEuropa. In Réunion, the additions cover sweet-potato investments already madeEuropa, seafood processing against lower-cost importsEuropa, vegetable oils for food servicesEuropa, kraft-paper bag makingEuropa, industrial gases for a pharmaceutical packaging centre serving hospitalsEuropa, cementEuropa — consumption at a historic low of barely 279,000 tonnes in 2024Europa against 420,000 in 2014Europa — and ventilation equipment from the island's sole manufacturerEuropa.
The document stresses the limits of what can be claimed: the code update itself brings legal certainty without further economic effectEuropa, and it is too early to assess the impact of the new codesEuropa since the volume of new production is uncertain. France will assess the additions in a new evaluation report due to the Commission by 30 September 2028Europa, with past evaluations having shown an overall positive impact from adding products.
Legal basis: Commission Staff Working Document SWD(2026) 661 accompanying proposals COM(2026) 661 and COM(2026) 662, based on Article 349 TFEUEuropa.
Advisers and businesses relying on the dock-dues differential in the French outermost regions should read the staff analysis for their sector's figures and track the Council's adoption of the extension and the new product codes.
