Apoderado General Despachante de Aduana common mistakes
Apoderado General Despachante de Aduana · Understand the traps and how to avoid them.
Applying the general most-favoured-nation tariff rate to an import without first checking whether a preferential trade agreement rate applies, or applying a preference without verifying the certificate of origin's validity and coverage of the goods actually shipped.
Candidates memorise the MFN schedule and treat the tariff question as finished once they find a rate, forgetting that the applicable duty is determined by origin and by the existence of a valid, correctly issued and correctly endorsed origin document.
What to do instead
Build a fixed sequence for every tariff question: classify the goods, establish origin, check whether a preferential regime exists for that origin, then verify that the origin certificate covers the specific goods, consignment and date. Answer the preference question explicitly before computing duty.
Classifying a product by its commercial name or by the heading that 'sounds right' instead of by the section and chapter notes, the legal texts of headings and, where relevant, the General Interpretative Rules in order.
Candidates rely on trade familiarity and on the first heading whose description resembles the product, skipping the notes that frequently exclude the goods from that chapter entirely.
What to do instead
Work through the GIR sequentially and write down the reasoning: section and chapter notes first, then heading text, then GIR 3 for mixed or composite goods, then GIR 6 for subheadings. Treat exclusionary notes as decisive, not as background.
Treating the transaction value as automatically acceptable and computing duty on the invoice price alone, without testing the conditions for using transaction value or adjusting for assists, royalties, commissions, packing, and the treatment of freight and insurance depending on the valuation basis used.
The invoice is the most visible number on the file, so candidates anchor on it and skip the legal test of whether the price was influenced by conditions or restrictions and whether dutiable additions are missing.
What to do instead
Before using transaction value, run through its conditions expressly. Then list each potential addition and deduction and state whether it is included or excluded and why. Distinguish clearly between the CIF and FOB bases and apply the one the applicable rule requires.
Confusing the destination that must be declared with the regime that is actually being requested, for example declaring a definitive import for goods that are intended for temporary admission or for entry into a free zone, or using a suspense regime for goods that will be consumed or transferred in the local market.
The paperwork looks similar across regimes and candidates focus on completing the declaration form rather than on matching the economic purpose of the operation to the legal regime.
What to do instead
For each scenario, state the intended economic use of the goods and the fate of the goods after the operation, then select the regime that matches. Check the conditions, guarantees and time limits of that regime before drafting the declaration.
Assuming that goods under a suspensive regime can remain there indefinitely or be disposed of freely, ignoring the time limits, the obligation to re-export or re-import, the requirement to keep the goods identifiable, and the obligation to regularise the regime when the goods are transferred or destroyed.
Suspensive regimes are learned as a list of names and benefits, and the conditions that attach to them are treated as formalities rather than as obligations whose breach triggers duty recovery and penalties.
What to do instead
For every special or suspensive regime, memorise four things together: the time limit, the guarantee required, the identifying or transformation conditions, and the regularisation events. Practise stating what happens to the duty if the deadline passes.
Calculating only the customs duty and omitting the other charges that form part of the tax base, or computing internal taxes on the customs value instead of on the customs value plus duty where the law requires that order of calculation.
Candidates treat each tax as an independent percentage of the invoice and do not build the cumulative base that the legislation prescribes.
What to do instead
Draw the calculation as a chain: customs value, then duty, then the base for each subsequent tax, then any additional charges. Recompute a full example from scratch each time rather than adjusting a remembered final figure.
Believing that the customs broker's or agent's responsibility ends when the declaration is lodged or when the client signs the authorisation, and failing to identify the specific duty of care owed when acting on behalf of an importer or exporter.
Candidates conflate the client's ownership of the goods with the broker's professional liability and do not distinguish the consequences of acting within a mandate from those of acting outside it.
What to do instead
Study the mandate relationship explicitly: what the broker certifies by signing, what must be verified against source documents, and what must be refused. For ethics questions, identify the specific professional duty engaged before evaluating the conduct.
Classifying a factual scenario as an administrative infringement when it meets the elements of a customs offence, or the reverse, without identifying the elements of each and without distinguishing intent from negligence.
Candidates answer from the severity of the outcome rather than from the legal elements, and the vocabulary of infringement and offence overlaps in ordinary usage.
What to do instead
For each scenario, list the elements required by the definition and check them one by one, expressly noting whether intent, knowledge or mere negligence is present. State the classification and the consequence separately.
Describing the customs clearance sequence in the wrong order, for example placing the payment of duties before acceptance of the declaration or treating inspection as automatic rather than as a selection outcome.
Candidates learn the steps as a loose list and do not anchor them to the moment the declaration is accepted, which is the point that fixes the applicable law and starts the procedural clock.
What to do instead
Memorise the sequence as a numbered chain from arrival and unloading through storage, declaration, acceptance, verification or release, and payment. Anchor everything to the legal effect of acceptance of the declaration.
Answering questions about the broker's role in customs procedures by describing ideal practice rather than the legally prescribed acts, such as which documents the broker must sign, what the authorisation must contain, and what happens when the declarant's instructions conflict with the law.
Candidates mix general professional good practice with the specific legal duties and fail to state the legal consequence of acting outside the mandate.
What to do instead
Separate the legal duty from the ethical recommendation in every answer. Cite what the declarant must do, what must be verified, and the consequence of non-compliance, then add the ethical dimension as a distinct point.
