Article 846U.K.
1.By way of derogation from Article 186 of the Code, returned goods in one of the following situations shall be exempt from import duties:
(a)goods which, after having been exported from the customs territory of the Community, have received no treatment other than that necessary to maintain them in good condition or handling which alters their appearance only;
(b)goods which, after having been exported from the customs territory of the Community, received treatment other than that necessary to maintain them in good condition or handling other than that altering their appearance, but which proved to be defective or unsuitable for their intended use, provided that one of the following conditions is fulfilled:
(b)such treatment or handling was applied to the goods solely with a view to repairing them or restoring them to good condition,
their unsuitability for their intended use became apparent only after such treatment or handling had commenced.
2.Where returned goods have undergone treatment or handling permitted under paragraph 1 (b) and such treatment would have rendered them liable to import duties if they had come under outward processing arrangements, the rules in force for charging duty under the said arrangements shall apply.
However, if goods have undergone an operation consisting of repair or restoration to good condition which became necessary as a result of unforeseen circumstances which arose outside the customs territory of the Community, this being established to the satisfaction of the customs authorities, relief from import duties shall be granted provided that the value of the returned goods is not higher, as a result of such operation, than their value at the time of export from the customs territory of the Community.
3.For the purposes of the second subparagraph of paragraph 2:
(a)repair or restoration to good condition which became necessary means: any operation to remedy operating defects or material damage suffered by goods while they were outside the customs territory of the Community, without which the goods could no longer be used in the normal way for the purposes for which they were intended;
(b)the value of returned goods shall be considered not to be higher, as a result of the operation which they have undergone, than their value at the time of export from the customs territory of the Community, when the operation does not exceed that which is strictly necessary to enable them to continue to be used in the same way as at that time.
When the repair or restoration to good condition of goods necessitates the incorporation of spare parts, such incorporation shall be limited to those parts strictly necessary to enable the goods to be used in the same way as at the time of export.
