When a new customs-approved treatment or use has not been given by the warehouse keeper at the end of the period for the goods to remain in the warehouse set by the administration or by the Community regulations in force, and in the absence of authorisation to extend the period by the administration, the warehouse keeper shall be summoned to comply with this obligation.
2. The notice referred to in 1 shall be served, failing which the warehouse keeper shall be obliged to pay a monthly penalty amounting to 1% of the value of the goods not removed from the warehouse, from the date of expiry of the period referred to in 1 until the date of removal or compulsory sale of the goods under the conditions set out in 3 of this article.
3. If the summons remains without effect within one month, a notice of assessment is issued against the warehouse keeper for the recovery of the penalty referred to in 2 of this article and the goods not removed from the warehouse may be sold automatically at public auction by the customs administration.
