Spanish customs post-clearance demand for duties and import VAT on goods already cleared

The case, in five lines

What is brought

Submissions on the proposal; against the assessment, a recurso de reposición (an appeal for reconsideration to the same authority) or a reclamación económico-administrativa (an economic-administrative claim), with suspension requested separately, and then judicial review (recurso contencioso-administrativo). In parallel, if the debt stems from an error by customs itself, an application for repayment or remission (arts. 116 to 121 of the Union Customs Code).

Before which court

Submissions and the reposición go to the customs and excise unit (dependencia de Aduanas e Impuestos Especiales) of the AEAT (the Spanish tax agency) that issued the assessment. The claim is filed through its electronic site and decided by the Tribunal Económico-Administrativo Regional (TEAR, the regional economic-administrative tribunal), with an onward appeal to the central tribunal (TEAC) above €150,000, or by the TEAC at sole instance if a central body issued the assessment. Judicial review goes to the Sala de lo Contencioso-administrativo (administrative chamber) of the Tribunal Superior de Justicia (regional High Court of Justice, art. 10.1.d LJCA, the Administrative Jurisdiction Act) or of the Audiencia Nacional (National High Court, art. 11.1.d LJCA), depending on whether the TEAR or the TEAC decided.

Deadline

30 days to respond to the proposal (art. 22.6 of the Customs Code and art. 8.1 of Delegated Regulation 2015/2446). One month from notification for the reposición or the claim (arts. 223.1 and 235.1 LGT, the General Tax Act), another for the alzada and two for judicial review (art. 46.1 LJCA); once they pass, the assessment is final. The customs debt cannot be notified more than three years after it arose (art. 103), a time bar (caducidad) suspended during the hearing and the appeal; import VAT has a four-year limitation period (art. 66 LGT).

Who can bring it

The debtor: the declarant and, in indirect representation, also the person on whose behalf the declaration was made (art. 77.3 of the Customs Code); for VAT, the importer (art. 86 of the VAT Act). Managora files the submissions, appeals, suspension request and repayment application under your authorisation (art. 46.2 LGT), without asking for your digital certificate; in judicial review, through a procurador (court representative) and a lawyer (art. 23.2 LJCA).

Financial risk

Appealing does not stop collection (art. 45.1 of the Customs Code): without payment or suspension, the debt moves to enforcement (apremio) with a surcharge. If you lose, interest is due for the whole suspended period (art. 233.12 LGT), although the appeal cannot leave the assessment worse for you (arts. 223.4 and 237.1 LGT). Judicial review may end with an order to pay costs. If the facts could amount to a criminal offence, customs has a longer period and that side of the matter is for the criminal courts: Managora does not handle criminal defence.

Dates first: three years from the moment each debt arose

Art. 103.1 of the Union Customs Code leaves no room: no customs debt may be notified once three years have passed since it arose. On import, the debt arises when the declaration for release for free circulation is accepted (art. 77.2), not on the invoice date or on payment, and the TEAC (Tribunal Económico-Administrativo Central, the central economic-administrative tribunal) describes that limit as a time bar (plazo de caducidad). If customs goes beyond it, the debt is extinguished (art. 124.1.a), and for those declarations there is no need to argue the merits.

What nobody tells you is that a post-clearance assessment usually spans several years and the limit is measured declaration by declaration: the oldest may already be out of time. The clock stops twice: from the moment customs informs you of its grounds for assessing until the deadline for your response ends, and for as long as any appeal you lodge lasts (art. 103.3). That second pause cuts both ways: if you win only on a procedural defect, customs may still have time to assess again.

The exception is the long period: if the debt arises from an act which, when committed, was liable to give rise to criminal proceedings, the three years become between five and ten (art. 103.2). In Spain, the Smuggling Act allows the assessment to be notified within the limitation period for the offence if the authorities have reported the facts, and referral to the criminal courts prevents neither assessment nor collection (fourth additional provision of Organic Law 12/1995). We challenge the assessment; Managora does not handle the criminal defence.

Import VAT runs on a different clock and a different base

Import VAT is assessed by customs in the same way as customs duties (art. 167.Dos of the VAT Act), but with a different limit: the four-year limitation period of the Ley General Tributaria (the General Tax Act, art. 66). That is why you may be charged VAT on imports whose duty can no longer be claimed. Its base is the customs value plus the duties and charges arising by reason of the import and the incidental expenses up to the first place of destination in the Community (art. 83.Uno).

This is the criterion that moves the most money. A customs information note of February 2023 maintained that duties form part of the VAT base even where they can no longer be assessed because the three years have passed. The TEAC, in two decisions of 16 December 2025, laid down the opposite as doctrine: if the customs debt is no longer enforceable because of the three-year time bar, its duties do not enter the VAT base either, because, although still legally owed, they are not enforceable.

In practice, imports between three and four years old deserve close scrutiny. If the new heading only changes the duty rate, the VAT difference arises solely from duties that are no longer enforceable and, under that criterion, disappears. If the value changes, for example because of royalties, the VAT base rises in its own right and that part can still be assessed. And watch the freight: up to the point of entry into the Union it is customs value (art. 71.1.e of the Code); from there to the first destination it bears no duty, but it does bear VAT.

The proposed assessment: 30 days worth more than an appeal

Before a decision adverse to you, customs must inform you of the grounds on which it intends to base it and give you the opportunity to make observations (art. 22.6 of the Customs Code), also when acting on its own initiative, as in a post-release control (art. 29). The delegated rules supplementing the Code set that period at 30 days. It may only be dispensed with in the cases listed in art. 22.6, such as where it may affect an investigation already opened to combat fraud, and the assessment must state its reasons and mention the right of appeal (art. 22.7).

It is the cheapest moment to win: there is still no assessment to pay or to secure. Request the file and read exactly what the proposal says: which heading it applies and why, what it adds to the value and on what data, which declarations it covers. And answer with evidence, not disagreement: technical data sheet and composition, laboratory analysis, licence and commission agreements, transport invoices by leg. What you do not argue now you can still argue later, but with the assessment issued and collection under way.

The hearing also moves the clock: from the moment customs informs you of its grounds until the period for observations ends, the three years in art. 103 are suspended (art. 103.3.b), so both dates should be noted. If customs issued the assessment without hearing you, or gave you a shorter period with no reason to justify it, that is a defect to be raised in the appeal against the assessment, together with the merits.

Against the assessment: reposición or claim, and then the court

Once the assessment is notified, you have one month from the following day to choose your filing. The recurso de reposición (an appeal for reconsideration to the same authority) is optional, is lodged with the unit that issued the assessment and must be decided within one month; without an answer, it may be treated as dismissed and the claim brought (arts. 222, 223 and 225 LGT). The reclamación económico-administrativa (a claim before the economic-administrative tribunals) is lodged within the same month with the body that issued the act, through its electronic site, which forwards it to the tribunal (art. 235). Both cannot be lodged at once: the second is declared inadmissible (art. 222.2).

What nobody tells you is that a claim lodged together with its submissions allows customs to annul its assessment in whole or in part before sending the file to the tribunal, something the law only permits if there was no reposición (art. 235.3). The reposición works for an obvious error; to dispute a heading or a value, it is usually better to go straight to the TEAR (Tribunal Económico-Administrativo Regional, the regional economic-administrative tribunal) with all the evidence, because in the alzada before the TEAC only evidence that could not be produced at first instance is admitted (art. 241.2). The TEAR decides at sole instance up to €150,000.

The economic-administrative tribunal has one year to decide (six months in the abridged procedure, below €6,000); once the year has passed, the claim may be treated as dismissed (art. 240.1 LGT). There are then two months to seek judicial review (art. 46.1 LJCA), through a procurador (court representative) and a lawyer, before the Sala de lo Contencioso-administrativo (administrative chamber) of the Tribunal Superior de Justicia (regional High Court of Justice) if the TEAR decided (art. 10.1.d) or of the Audiencia Nacional (National High Court) if the TEAC decided (art. 11.1.d). The statement of appeal rights (pie de recurso) on each act governs and is always checked. The prior attempt at settlement under art. 5 of Organic Law 1/2025 is not required here: it applies only to civil proceedings.

Appealing does not stop collection: suspension with a guarantee or a waiver

Art. 45.1 of the Customs Code puts it bluntly: appealing does not suspend the contested decision, and an assessment that is neither paid nor suspended moves to enforcement (apremio) with a surcharge. Suspension is requested in a separate application, when the claim is lodged or later, to the body that issued the act (art. 40 of the Review Regulation, Royal Decree 520/2005), and it is automatic if the amount, interest and surcharges are secured by a deposit, a guarantee from a credit institution or mutual guarantee company (sociedad de garantía recíproca), or surety insurance (art. 233.1 and 2 LGT). With a sufficient guarantee, it takes effect from the request.

If you cannot obtain a bank guarantee, other sufficient guarantees may be offered, explaining why those cannot be provided (art. 233.3), or a full or partial waiver sought, which the tribunal grants if enforcement could cause harm that is difficult or impossible to repair (art. 233.4); art. 45.3 of the Customs Code also dispenses with the guarantee where customs suspends on well-founded doubts or irreparable damage and a documented assessment shows serious economic or social difficulties. A waiver is won with figures: the tribunal declares the request inadmissible if the documents show no indication of the harm (art. 233.6). An arithmetical, material or factual error allows suspension without a guarantee (art. 233.5).

And timing matters: with the debt already in enforcement, applying for suspension with other guarantees or a waiver does not halt collection, although what has been done since the request is annulled if suspension is granted (art. 233.9), so it is requested before the payment deadline expires. Suspension lasts throughout the economic-administrative route (art. 233.10) and continues into judicial review if, within the period for bringing it, the AEAT (the Spanish tax agency) is told of the proceedings and the suspension request (art. 233.11). If you end up paying, interest is due for the whole period (art. 233.12), although, with the act suspended, it stops accruing once the reposición or the claim goes beyond its maximum decision period without a decision (arts. 225.4 and 26.4 LGT).

The merits: the heading, the value and customs' own error

On classification, the dispute is which subheading of the Combined Nomenclature applies (art. 57 of the Customs Code), using the general interpretative rules and the explanatory notes, and the evidence is the product: composition, function, technical data sheet and, if needed, laboratory analysis. Binding tariff information (BTI, IAV in Spanish) that you held when importing binds customs for declarations made after it took effect, if the goods match the description in every respect (art. 33.2 and 4). Requested now, it does not fix the past, but it settles the heading for what you go on importing.

On value, the price actually paid or payable governs, plus only what art. 71 lists: commissions other than buying commissions, what you supplied to the manufacturer free or at reduced cost (moulds, tools, design work done outside the Union), transport and insurance up to the point of entry into the Union, and royalties related to the goods paid as a condition of sale. All on objective and quantifiable data (art. 71.2), and nothing else (art. 71.3). That is why the contracts decide: a royalty that is not a condition of sale, or your buying agent's commission, does not go in. Where the parties are related, customs may reject the price if the relationship influenced it (art. 70.3.d).

If the debt stems from an error by customs itself, for example because it had checked the goods and accepted the same heading, the TEAC points to repayment or remission: it succeeds if you could not reasonably have detected the error and acted in good faith (art. 119), or on grounds of equity, in special circumstances involving neither fraud nor obvious negligence (art. 120). An incorrect certificate of origin issued by the exporting country's authorities is also an error, unless, as a rule, it was based on inaccurate information from the exporter (art. 119.3). It must be requested within three years of notification of the debt, a period the appeal suspends (art. 121). Since the TEAC has also accepted the error being raised in an appeal, it is advisable to use both routes.

How we run the case, step by step

1. 1

   Pin down the dates of each declaration

   With the declarations (the DUA or, since 14 October 2025, the H1), their acceptance dates and the receipts for the proposal and the assessment, we work out which debts are still within the three years, which VAT is within the four, and when the month to appeal runs out.

2. 2

   Read the file and the reasoning

   We request the file and separate what customs proves from what it merely asserts: the heading and its reasoning, each item added to the value with its data, and whether there was a hearing and with what deadline.

3. 3

   Respond within the 30 days

   If you are still at the proposal stage, we file the observations under your authorisation with the technical and contractual evidence, and note when the period ends, since it also suspends the three years.

4. 4

   Claim or reposición within the month, with suspension

   We choose the filing according to the error and the amount and, separately, request suspension with the guarantee you arrange with your bank or a mutual guarantee company, or with a waiver if you cannot obtain one.

5. 5

   Repayment or remission in parallel

   If customs had already accepted the same heading, or the certificate of origin was issued by the exporting country's authorities, we also apply for repayment or remission under art. 119 of the Customs Code, which the appeal does not replace.

6. 6

   Judicial review if the claim fails

   Within two months, before the relevant chamber of the Tribunal Superior de Justicia (regional High Court of Justice) or the Audiencia Nacional (National High Court), through a procurador and a lawyer, informing the AEAT of the proceedings so that suspension continues.

The law that applies

• Arts. 22, 29, 44 y 45 del Código Aduanero de la Unión. Before an adverse decision, including one taken on its own initiative, customs states its grounds and opens a period for observations; the decision gives reasons and mentions the right of appeal. Any decision of direct and individual concern may be appealed, and appealing does not suspend it unless there are well-founded doubts or a risk of irreparable damage, with a guarantee where duties are payable. 02013R0952-20221212
• Arts. 77, 102, 103 y 124 del Código Aduanero de la Unión. The import debt arises on acceptance of the declaration. It may not be notified after three years, or between five and ten if the act was liable to give rise to criminal proceedings; the period is suspended during the hearing and the appeal and, once it expires, the debt is extinguished. 02013R0952-20221212
• Arts. 33, 34, 57, 70 y 71 del Código Aduanero de la Unión. BTI binds customs for declarations made after it takes effect, is valid for three years and does not lose validity retroactively. Classification means determining the subheading of the Combined Nomenclature; value is the transaction value, adjusted only by the items listed in art. 71. 02013R0952-20221212
• Arts. 116, 117, 119, 120 y 121 del Código Aduanero de la Unión. Repayment or remission for overcharging, for an error by the authorities that a debtor acting in good faith could not detect, or on grounds of equity, requested within three years of notification of the debt, a period suspended by an appeal; never where the debtor acted fraudulently, and from €500,000 the Commission may decide. 02013R0952-20221212
• Arts. 222, 223, 225, 233 y 235 de la Ley General Tributaria. Optional reposición within one month, decided within another and incompatible with a simultaneous claim; a claim within one month lodged with the body that issued the act, which may annul it if there was no reposición; automatic suspension with a guarantee, a waiver for harm that is difficult or impossible to repair, and interest for the suspended period. BOE-A-2003-23186
• Arts. 83, 86 y 167 de la Ley del IVA. Import VAT is assessed in the same way as customs duties; its base is the customs value plus the taxes and charges arising by reason of the import, other than VAT itself, and the incidental expenses up to the first destination in the Community; the person liable is the importer. BOE-A-1992-28740
• Arts. 10, 11 y 46 LJCA. Decisions of the TEARs that end the economic-administrative route go to the Salas de lo Contencioso-administrativo (administrative chambers) of the Tribunales Superiores de Justicia (regional High Courts of Justice), and those of the TEAC to that of the Audiencia Nacional (National High Court), within two months of notification. BOE-A-1998-16718
• Disposición adicional cuarta de la LO 12/1995. Referral of the case to the criminal courts does not prevent the customs debt from being assessed or collected through enforcement, and it may be notified within the limitation period for the smuggling offence where the authorities have reported the facts and have what they need to assess it.
