Article 30 TFEU

The Political and Sociological Context

Article 30 of the Treaty on the Functioning of the European Union^[1] was introduced as part of the provisions relating to the free movement of goods. The crux of this is described in Article 28 TFEU, which provides that “the Union shall comprise a Customs Union which shall…involve the prohibition between Member States of customs duties on imports and exports”.^[2] As the European Commission has observed, “the single market can only function properly when there is a common application of common rules at its external borders”.^[3]  Article 30, which relates to customs duties on imports and exports and “charges having equivalent effect”,^[4] was enacted in order to support this principle.^[5]

The Legal Context

As observed above, Article 30 applies not only to customs duties imposed on imports and exports, but to any charges having an equivalent effect thereto.^[6] It is therefore clear that the provision was intended to have a wide legal ambit in order to prevent States from being able to introduce charges which, although not customs duties per se, were still capable of having a protectionist effect and therefore undermining the operation of the free movement of goods within the Union.

This is clear from Commission v Italy,^[7] in terms of customs duties. There, it was held that the relevant question to be determined is not the intended effect of the charge imposed, but whether the actual effect was that “trade in the goods in question is hindered by the pecuniary burden”^[8] imposed by the tax. Of course, the decision in that case rested on the application of the provisions of the Treaty Establishing the European Economic Community,^[9] rather than Article 30 and one may therefore wonder whether introducing Article 30 had any new legal purpose.

In this regard however, it should be observed that Article 30 does not aim to distinguish between when duties are imposed on goods; this should be seen as a departure from the old Article 12 EEC^[10] which prohibited new duties and charges with equivalent effect and increases in existing ones, Article 13 EEC^[11] which provided for the progressive abolition of existing import duties and charges having equivalent effect, and Article 16 EEC,^[12] which applied to exports.  The expiry of the transitional periods rendered this distinction between new and existing duties redundant^[13] and indeed, it is submitted that this ensures that Article 30 supports a unified free movement principle, rather than the more fragmented approach which existed in relation to the imposition of charges and duties under the old Articles 12 and 13 EEC. The Treaty of Amsterdam replaced Article 12 with a general prohibition and repealed Articles 13–17; the prohibition became Article 25 EC and was subsequently renumbered Article 30 TFEU.^[51]

Key Operation and Changes to the Law

Article 30 is not concerned with the subjective intentions of the State imposing the infringing tax; rather, it looks to the actual effect of the tax on the free movement principle.^[14] As Craig and de Burca observe, this interpretation of the Article is necessary to avoid its applicability being “significantly weakened if a State could argue that a duty or charge should not be prohibited because its purpose was in some sense non-fiscal”.^[15]

Article 30 goes beyond relating only to customs duties, but also applies to any charges which have an equivalent effect. It has been held that Article 30 is triggered whenever a charge is introduced on a good by reason of its crossing a frontier between Member States, “even if it is not imposed for the benefit of the State, is not discriminatory or protective in effect and if the product on which the charge is imposed is not in competition with any domestic product”.^[16]  Indeed, the law now goes further than this and provides that even where a charge is not imposed on a product, but rather on a “necessary activity in connection with the product”,^[17] Article 30 or Article 110 may apply, depending on the nature of the charge. In Essent, a surcharge on both domestic and imported electricity constituted a charge having equivalent effect where the use of its proceeds wholly offset the burden on domestic electricity; if the burden was only partly offset, it constituted discriminatory internal taxation under what is now Article 110.^[18] The operation of Article 30 and its predecessors therefore ensures that charges having an equivalent effect to customs charges cannot be used to circumvent the aims of the free movement principle.

There are a number of circumstances in which Article 30 does not apply, but these fall outside the definition of a charge having equivalent effect, rather than operating as exceptions to the prohibition.^[19] This includes charges made for inspections required to be carried out by EU law,^[20] where the imposed charges fulfil a number of conditions, namely that the charge does not exceed the actual cost of the inspection; the inspections are obligatory and uniform for all the products concerned in the EU; they are “prescribed by Community law in the general interest of the Community”; and they promote the free movement of goods, in particular by neutralising obstacles arising from unilateral inspections.^[21]  Charges are also permitted where they constitute proportionate payment for a service actually rendered which confers a definite, specific benefit on the trader, although again it is clear from Commission v Belgium (Poultrymeat Inspection Case),^[22] that this applies in limited circumstances. A general system of internal taxation applied systematically according to the same objective criteria, irrespective of origin, falls under Article 110 instead. Articles 30 and 110 are mutually exclusive; Article 36 cannot justify a charge prohibited by Article 30.^[52]

It is therefore clear that the changes made to the law by Article 30 and its predecessors operate to ensure the effective operation of the free movement of goods principle so that charges having equivalent effect cannot be used to undermine that principle, regardless of the intention of the imposers of such charges.

Article 34 TFEU

The Political and Sociological Context

Article 34 TFEU^[23] is the key provision relating to the prohibition on quotas and measures which have an equivalent effect to such quantitative restrictions.^[24]  Article 34 provides that, “quantitative restrictions on imports and all measures having equivalent effect shall be prohibited between Member States”.^[25] The Article therefore supports the political principle of the free movement of goods by which trade is promoted throughout the Customs Union. It operates as an “anti-discrimination rule”^[26] and also prohibits unjustified non-discriminatory obstacles to market access. It complements the rules prohibiting the imposition of customs duties and equivalent charges.  Politically, the operation of Article 34 has been controversial due to the fact that rather than simply preventing the imposition of charges which may have a greater effect on imported than domestic products, Article 34 has a role in influencing the regulatory policies of Member States.^[27] It is suggested therefore that Article 34 has the potential to go beyond the politically uncontroversial economic aims of promoting the Customs Union and instead represent an attempt to harmonise regulatory policies across the EU.^[28]

The Legal Context

As observed above, Article 34 applies not only to quantitative restrictions, but also to Measures Having Equivalent Effect to Quantitative Restrictions (MEQRs).  The former have been defined as being “measures which amount to a total or partial restraint of, according to the circumstances, imports, exports or goods in transit”.^[29] In terms of the latter, the key case is Procureur du Roi v Dassonville,^[30] in which the Court held that “all trading rules enacted by Member States, which are capable of hindering, directly or indirectly, actually or potentially, intra-Community trade”^[31] are to be viewed as MEQRs.  It was later clarified, in Cassis de Dijon,^[32] that such measures did not need to be discriminatory and that Article 34 could apply to measures which were directed at both domestic and imported products where they imposed product requirements on goods lawfully manufactured and marketed in another Member State, unless the measures could be shown as necessary to ensure, in particular, the effectiveness of fiscal supervision, the protection of public health, the fairness of commercial transactions and the defence of the consumer.^[33] These mandatory requirements are non-exhaustive and include, for example, environmental protection. In principle, they justify indistinctly applicable measures, and any restriction must be proportionate. Goods lawfully manufactured and marketed in another Member State must generally be admitted unless a restriction is justified.

Despite Article 34 applying to non-discriminatory measures, it is clear that the Article does also apply where measures are discriminatory, including for example measures relating to markings stating the origin of goods.  For example, in Commission v United Kingdom,^[34] it was held that such policies “ha[ve] the effect of slowing down economic interpenetration in the Community by handicapping the sale of goods produced as the result of a division of labour between Member States”^[35] and thus constituted a discriminatory policy. What should however be noted is that the legal ambit of Article 34^[36] extends to unjustified measures, whether discriminatory or otherwise, which hinder intra-EU trade, complementing the rules contained in Articles 28-30 TFEU.^[37]

Article 36 permits restrictions justified by public morality, public policy or public security; protection of the health and life of humans, animals or plants; protection of national treasures possessing artistic, historic or archaeological value; or protection of industrial and commercial property. They must be proportionate and must not constitute arbitrary discrimination or a disguised restriction on trade. Where EU legislation exhaustively harmonises the matter, national measures are assessed under that legislation. The Treaty goods rules cover products originating in Member States and third-country products in free circulation within the EU.^[53]

Key Effects

Whilst Article 34 clearly supports the principle of free movement of goods and thus promotes the Customs Union as a fundamental principle of the EU, its exceptionally wide ambit has been criticised for going beyond supporting free movement and instead undermining State “regulatory autonomy”.^[38]

This is clear for example from Torfaen BC v B&Q^[39] in which the Court considered whether a national rule preventing retailers from opening shops on a Sunday was compatible with what is now Article 34. Whilst the Court accepted the legitimacy of the rule’s socio-cultural aims,^[40] it left to the national court whether the restrictive effects exceeded those intrinsic to rules of that kind. It is argued that the potential that Article 34 could be used in circumstances beyond those relating to market access, and instead relating to how those goods could be sold, was a step too far.^[41]

One might therefore expect the fact that the Court has sought to limit Article 34 by excluding certain selling arrangements which apply to all relevant traders in the territory and affect domestic and imported goods equally in law and fact,^[42] to be a welcome step. Although it cannot be discussed extensively due to the short nature of this work, the problem with this approach is that where rules related to selling are intertwined with the nature of the product itself, Article 34 still applies;^[43] the same position may be found where even though a rule is ostensibly related to selling, it has a differential impact in law or fact, impacting on imported products to a greater extent than domestic products.^[44]  Aside from the confusion this creates in terms of selling rules, it seems that Keck^[45] does not really limit Article 34 in any substantial manner and it is suggested that its usage is still likely to be problematic to Member States as it goes far beyond mere market access issues,^[46] the ostensible aim of the Article.  Whilst it may be true that later case law does signify a resurgence of the market access test^[47] in line with Dassonville,^[48] Keck^[49] has not been overruled^[50] and it is therefore difficult to accept that its problematic results no longer exist. Restrictions on the use of goods can also impede market access. In Amazon EU (C-366/24, 18 December 2025), the Court reaffirmed Keck but held that minimum delivery charges for books not collected from a retailer were not an exempt selling arrangement and constituted an MEQR under Article 34.^[54]

2026 update

Brexit: Since the transition period ended on 31 December 2020, Articles 30 and 34 no longer govern Great Britain’s trade with EU Member States as intra-EU trade. The UK has left the EU Customs Union. UK-EU trade is now subject to the Trade and Cooperation Agreement (TCA) concluded in December 2020. While the TCA provides for zero tariffs and zero quotas on goods that meet rules of origin requirements, this does not remove customs formalities, declarations or applicable regulatory checks. Article 30 itself prohibits customs duties and equivalent charges, rather than all border formalities.^[55]

Northern Ireland: The Windsor Framework amended the Protocol on Ireland/Northern Ireland; it did not simply replace it. Northern Ireland remains part of the UK customs territory, but specified EU customs and goods rules apply under the Framework. Article 5(5) expressly applies Articles 30 and 110 TFEU to and in the UK in respect of Northern Ireland and prohibits quantitative restrictions between Northern Ireland and the EU. Article 7(1) also applies Articles 34 and 36 to the placing on the Northern Ireland market of goods imported from the EU, without prejudice to the EU legislation listed in Annex 2.^[56]

EU law: Articles 30 and 34 remain in force within the European Union. Commission v Italy (Statistical Levy) and Sociaal Fonds voor de Diamantarbeiders (Joined Cases 2 and 3/69) remain authorities on charges having equivalent effect. The customs-duty prohibition directly confers enforceable rights on individuals. Commission v Germany explains the conditions for permitted charges relating to inspections required by EU law.^[57]

Relevance of EU case law in UK courts: Historical disputes remain subject to the law and transitional provisions applicable to them. EU case law can also remain relevant, and may be binding, in interpreting assimilated law under section 6 of the European Union (Withdrawal) Act 2018, subject to its rules on departure from that case law. This does not restore the general application of Articles 30 and 34 to Great Britain. The general saving of directly effective EU rights under section 4 ended at the end of 2023; the distinct Windsor Framework obligations continue through section 7A.^[58]
