  1. The Lessee may not rent, pawn, pledge or otherwise use the rental property in exchange for a fee. The Lessee is not entitled to a lien or right of retention. In the event that third parties assert a lien, the Lessee must pay the transfer costs.
  2. Technical alterations, as well as defect rectifications undertaken by the Lessee in accordance with his obligation to keep the units in working order, may only be carried out with the written consent of the Owner. This is particularly true for actions on the container and on all significant components of the units. The costs of defect rectifications and for the replacement of missing equipment are to be borne by the Lessee.
  3. At the time of return, the Lessee must return the units in the same physical condition as at the beginning of the lease; this also applies to labels and other markings. The Owner has the right to decide whether to accept equipment differing from its original condition at current market value or insist on the restoration of the units, with the costs charged to the Lessee.
  4. Except for technical defects produced by contractually and functionally accordant use of the units, for which the Lessee is required to furnish proof, the Lessee is for all damages. The lease period will continue during the time that the required measures are taken. The following is a non-exhaustive list of potential defects and charges:
    1. Internal and external damage to the container (corrosion, dents, etc.) or the lining (if applicable).
    2. Damaged or missing equipment.
    3. Damage to the insulation and heating equipment (if applicable).
    4. Cleaning of the interior of the container (if necessary).
    5. Transport costs to and from the effective depot.
    6. The Lessee is responsible for ensuring that the rental property complies with all legal, regulatory, and especially hazardous material and storage regulations.
  5. In the event of changes in public regulations during the term of a lease, the Owner is fundamentally not responsible for technically necessary modifications.
  6. Exceptions are made for leases in which a specific use provision is stipulated for which the rental property was, however, not exclusively made, or the cargo is subject to a change in regulatory arrangements and the Lessee can prove that he did not have and could not have had knowledge thereof. In this case, the Owner is obliged to make the required technical adaptations to the rental property or provide suitable replacement equipment, but he is authorized to obtain a higher rental price. If the Lessee does not agree to the higher rental price, he can exercise an extraordinary right of termination.
  7. Leases for which the rental property was exclusively produced – or significantly altered – for a specific application preclude the Lessee of the right to terminate. These following cases are excluded:
    1. If the Lessee offers to have the measures to adapt to the changed requirements properly carried out at his own expense.
    2. If the Lessee can prove that the Owner could have re-leased the units elsewhere.
  8. The Lessee is obliged to carry out repairs and technical modifications such that legal provisions and standard requirements for the operation and transportation of the rental property are met.
  9. The Owner reserves the right to have the rental property inspected by an expert or to inspect it himself after a reasonable pre-notice. If the Owner has information indicating use of the property that does not conform to the contract, the pre-notice is unnecessary.

6 Maintenance and periodic testing during the lease period

  1. For rental property that is used for the storage or transport of hazardous materials as defined in the hazardous goods regulations, a legally prescribed WHP (re-examination) must be carried out. After due notice by the Owner at least 60 days before the review period, the Owner and Lessee must agree on the depot at which the WHP will be carried out. The Lessee is responsible for all costs incurred for missing the announced inspection time. Rental property which is filled at the time of the examination can be emptied before being subjected to the proposed WHP.
  2. The inspection fees will be borne by the Owner.
  3. All costs associated with preparations for the test (e.g. cleaning) and the removal of damages (from normal wear and tear) will be charged to the Lessee.
  4. If the Lessee carries out or commissions a WHP, he must have a certificate of inspection issued and sent to the Owner.
  5. For rental property equipped with additional electrical equipment, an examination of the installations according to DGUV V3 (Ordinance on Industrial Safety and Occupational Health and Safety Regulation) shall be conducted. The Lessee is responsible for all costs incurred for the audit in accordance with DGUV V3 as well as for any costs incurred by missing the announced inspection. If the operating permit for the rental property is invalidated due to skipping or missing the examination, the Lessee has no right to immediate termination and the lease retains its validity.

7 Termination of the lease and return of the rental property

  1. Superordinate to the provisions set out in Clause 2, the lease ends only when the rental property is returned to the contracted depot in the following condition:
    1. Completely emptied with no product remnants or deposits. Any product remnants of up to 30 kg will be documented (with illustrations) and cleared for disposal without consulting the Lessee. The resulting costs shall be borne by the Lessee. Same state of cleanliness of inner container, of all equipment and of the outer shell, as documented at the commencement of the lease.
    2. The container and all equipment are free of defects and in good working condition.

The condition of the rental property as well as that of the associated equipment is manifested by the input report, the costs of which are borne by the Owner.
  3. The Owner will inform the Lessee of the incongruities in writing and the Lessee is required to rectify the damages within a reasonable period of time. If he does not, the Owner will commission the repair work and invoice the costs to the Lessee.
  4. The Owner is required to bear the costs for the repair of damage caused by a reasonable degree of wear resulting from contractual and proper use. The Owner must inform the Lessee in writing of damages beyond a reasonable level for contractual use under Clause 538 BGB. The Lessee must then provide proof of contractual use and proper treatment. Appropriate treatment and utilization as specified in the contract generally preclude the following damages:
    1. Any damage to fixtures, equipment, furnishings and gaskets.
    2. Cracks, dents and corrosion in the container or the frame.
    3. Damage (including corrosion) of the heating system, its controls or the insulation.
  5. The Owner will provide the Lessee with a cost estimate for repairing the damage. The Lessee is obliged to commission the repair work and can verify the appropriateness of the measures by visual inspection in advance.
  6. The Owner is authorized to order the repair measures (including cleaning) at the Lessee’s expense if the Lessee a) has not commissioned the repairs himself within 2 weeks, or b) has not declared his willingness to assume the costs within a week and the Owner has already unsuccessfully set a one-week deadline to repair the damages.
  7. The Lessee must supply comprehensive information regarding the last product to the Owner in writing. For hazardous materials, an MSDS (Material Safety Data Sheet) is to be completed.
  8. If the contract parties cannot agree on the status of the rental property and the corresponding responsibility for covering the costs at the end of the contract, an independent evaluator will be appointed whose assessments are binding for Owner and Lessee. The Owner will propose an evaluator to the Lessee and notify him that if he does not respond within 5 working days, the Owner is entitled to authorize the evaluator on behalf of both parties. The costs of the evaluation will be distributed according to the cost absorption obligations as decided by the evaluator.
  9. Concealed damages that were not identified and documented in the receiving inspection must be immediately indicated to the Lessee in writing by the Owner. The Owner will also request a joint determination of the detected damage. If the Lessee fails to comply within 10 working days of notification of a joint determination, the notification of the concealed damages will become binding for the Lessee, who is then obliged to assume the costs.

8 Liability and insurance

  1. The Lessee must insure the rental property against the risk of loss, damage and destruction for the duration of the rental contract, because he is responsible for the rental property during this time. The Lessee is obliged to provide a copy of the original insurance coverage policy upon request by the Owner.
  2. The Lessee pledges not to load the rental property with products likely to damage it.
  3. The Lessee is liable for all damage to the rental property and equipment during the period that the units are in his sphere of responsibility.

The Owner is not liable for  lost or damaged cargo unless the Lessee can provide evidence of technical defects or faulty construction in the rental property, in which case the Owner would then be responsible.
  6. The maximum liability of the Owner is limited to one year’s rent. If the lease period is shorter than a year then the Owner’s maximum liability is twelve times the value of one month’s rent. These restrictions do not apply in the following cases: deliberate intention, breach of a contractual obligation, or injury to health or life.
  7. The Lessee must immediately notify the Owner in writing in the event of a total loss (whether because the repair costs exceed the value of the unit or the unit is unrecoverable), and the facts must be verified by inspection or by valid documents proving total loss.
  8. The Lessee is obliged to pay the stated present value of the rental property to the Owner within 30 days of being billed. The end of the lease term is the last day of the month in which payment of the present value is received by the Owner.

  12. The following percentage values calculated from the date of manufacture apply as present value:
    1. up to 11 months 100%
