Transactions covering shipments to or from other countries may also be in accordance with these standards and practices and may be modified by mutual agreement between buyer and seller. These specifications are guidelines for buying and selling container glass cullet and always subject to the buyer and seller’s agreement. Scrap Glass Definitions Container Glass Cullet: crushed or whole scrap soda-lime- silica container glass. Unprocessed Container Glass Cullet: broken or whole scrap glass containers that comply with the proper ISRI glass specifi- cations. Processed (Furnace Ready) Container Glass Cullet: crushed and whole contaminate-free scrap container glass that complies with the proper ISRI glass specifications. Organic Matter: consists of organic materials that are non- container glass items; for example, paper labels should not exceed 0.2%. Ferrous Materials: are magnetic metals, i.e. steel, iron, etc., and therefore must be removed during scrap glass process- ing. Non-ferrous Materials: are non-magnetic metals, i.e. alu- minum, lead, copper, etc., and therefore must be removed during glass processing. The Purchase Agreement Each transaction covering the purchase or sale of container glass cullet should be confirmed in writing and include agreement on the following items: 1. Product Where possible, each container glass cullet grade shall be specified in accordance with the grade as defined. 2. Quantity Where possible, the quantity shall always be specified in terms of a definite number of tons of 2,000 pounds each. A. If the quantity is specified in tons, the order shall be con- sidered completed when aggregate shipments are 5% under or over the quantity ordered. B. If the quantity is specified in carloads or truckloads, a “load” shall be defined as a truck, trailer, or railroad car loaded to full visible capacity not to exceed established legal weight limits. 3. Packaging It should be stated whether shipped units are to be in boxes, or in bulk by railroad car, truck, or trailer. Where possible, approximate weights should be specified. 4.
