Arrival"; Warranty of Condition on Arrival.

Under a contract containing a term C.I.F. or C. and F.

(1) Where the price is based on or is to be adjusted according

to "net landed weights", "delivered weights", "out turn" quantity or

quality or the like, unless otherwise agreed the seller must

reasonably estimate the price. The payment due on tender of the

documents called for by the contract is the amount so estimated, but

after final adjustment of the price a settlement must be made with

commercial promptness.

(2) An agreement described in subsection (1) or any warranty of

quality or condition of the goods on arrival places upon the seller

the risk of ordinary deterioration, shrinkage and the like in

transportation but has no effect on the place or time of

indentification to the contract for sale or delivery or on the

passing of the risk of loss.

(3) Unless otherwise agreed where the contract provides for

payment on or after arrival of the goods the seller must before

payment allow such preliminary inspection as is feasible; but if the

goods are lost delivery of the documents and payment are due when

the goods should have arrived.
