Artikel 23

1. Subject to Article 19, in respect of goods which, by reason of their nature, are generally subject to wastage by the sole fact of carriage, the carrier shall only be liable to the extent that the wastage exceeds the following allowances, whatever the length of the route:
a) Two per cent of the mass for liquid goods or goods consigned in a moist condition;
b) One per cent of the mass for dry goods.
2. The limitation of liability provided for in paragraph 1 of this Article may not be invoked if, having regard to the circumstances of a particular case, it is proved that the loss was not due to causes which would justify the allowance.
3. Where several packages are carried under a single consignment note, the wastage during carriage shall be calculated separately for each package if its mass on consignment is shown separately on the consignment note or can be ascertained otherwise.
4. In case of total loss of goods or in case of loss of a package no deduction for wastage during carriage shall be made in calculating the compensation.
