possibility of unlifted cement quantity

[Darina_007]

Помогите, пожалуйста, разобраться, что такое unlifted cement quantity в контексте:

The buyer shall have to pay 111 dollars to the exporter at the beginning of the contract. This should be regarded a warranty against the possibility of unlifted cement quantity. This is "liquidated damage for stocking and financing cost" and to be transferred after signing the contract.

и еще "liquidated damage for stocking and financing cost" - «заранее оцененные убытки за хранение на складе и затраты на финансирование»?

Признательна за любую помощь.
