Article 52
1. Equipment which has been admitted duty-free in accordance with the conditions laid down in Article 51 may not be lent, hired out or transferred, whether for a consideration or free of charge, without prior notification to the competent authorities. 2. Should equipment be lent, hired out or transferred to an establishment or organisation entitled to benefit from relief pursuant to Article 51, the relief shall continue to be granted provided the establishment or organisation uses the equipment for purposes which confer the right to such relief. In other cases, and without prejudice to the application of Articles 44 and 45, loan, hiring out or transfer shall be subject to prior payment of import duties, at the rate applying on the date of the loan, hiring out or transfer, on the basis of the type of equipment and the customs value ascertained or accepted on that date by the competent authorities. 3. Establishments or organisations referred to in Article 51(1) which no longer fulfil the conditions to qualify for relief or which are proposing to use equipment admitted duty-free for purposes other than those provided for by that Article shall so inform the competent authorities. 4. Equipment used by establishments or organisations which cease to fulfil the conditions giving entitlement to relief shall be liable to the relevant import duties at the rate applying on the date on which those conditions cease to be fulfilled, on the basis of the type of article and the customs value ascertained or accepted on that date by the competent authorities. Without prejudice to Articles 44 and 45, equipment used by the establishment or organisation benefiting from the relief for purposes other than those provided for in Article 51 shall be liable to the relevant import duties calculated as applicable on the date on which it is put to another use, on the basis of the type of equipment and the customs value ascertained or accepted on that date by the competent authorities.
