The carrier shall be entitled to recover the cost of his request for instructions and any expenses entailed in carrying out such instructions, unless such expenses were caused by the wrongful act or neglect of the carrier.

In the cases referred to in article 14, paragraph 1, and in article 15, the carrier may immediately unload the goods for account of the person entitled to dispose of them and thereupon the carriage shall be deemed to be at an end. The carrier shall then hold the goods on behalf of the person so entitled. He may however entrust them to a third party, and in that case he shall not be under any liability except for the exercise of reasonable care in the choice of such third party. The charges due under the consignment note and all other expenses shall remain chargeable against the goods.

The carrier may sell the goods, without awaiting instructions from the person entitled to dispose of them, if the goods are perishable or their condition warrants such a course, or when the storage expenses would be out of proportion to the value of the goods. He may also proceed to the sale of the goods in other cases if after the expiry of a reasonable period he has not received from the person entitled to dispose of the goods instructions to the contrary which he may reasonably be required to carry out.

If the goods have been sold pursuant to this article, the proceeds of sale, after deduction of the expenses chargeable against the goods, shall be placed at the disposal of the person entitled to dispose of the goods. If these charges exceed the proceeds of sale, the carrier shall be entitled to the difference.

The procedure in the case of sale shall be determined by the law or custom of the place where the goods are situated.
