IX.6.4.2. Collection of debt or other liens
Article 11, paragraph 2, of the TIR Convention
The collection of the debt payable from the responsible person or persons must be carried out in accordance with the procedures laid down (see Part VIII). Under the TIR Convention, the competent authorities must require the responsible person or persons to pay any duties and taxes owed. However, in cases where the TIR Carnet holder resides in a third country, it will not always be possible to guarantee payment of the outstanding taxes. This is recognized by the TIR Convention when it uses the formulation "shall, as far as possible, require payment of such sums from the persons directly liable."
The phrase "as far as possible" implies that the competent authorities should make every effort to require payment. This effort should involve, at a minimum, a formal request for payment addressed to the person in question.
If payment has not been made within one month of the debt being communicated to the debtor, the amount will be claimed from the guarantor association, up to the limit set by the guarantee.
