Section 61411 does not apply to the purchase of manufacturing milk which is necessary to meet an unanticipated increase in demand or an unanticipated shortage in the supply of a handler if the quantity purchased from any one producer does not exceed 5,000 gallons in any one month. However, if the producer is a cooperative association acting as a producer, the total quantity purchased shall not exceed 30,000 gallons per month.
For a single transaction between a producer and handler, payment shall be made for the amount of milk delivered during the first 15 days of any calendar month not later than the first day of the next following month and payment shall be made for the amount of milk delivered during the remainder of the month not later than the 15th day of the next following month, unless the milk is subject to a pooling plan as authorized in Chapter 3 (commencing with Section 62700) and the pooling plan provides for different dates and methods of payment, in which case the date and method of payment for the milk shall be as provided for in the pooling plan.
