美国采购需求：香菇菌种

We are currently exploring potential suppliers to meet our production demands and are particularly interested in your offerings of Shiitake substrate blocks/logs. We'd appreciate it if you could share bulk pricing options along with your minimum order quantity for a single shipment. Additionally, let us know if you have any flexibility with the MOQ. We'd also like detailed information about the substrate composition, such as the type of sawdust blend and any supplementation levels, as well as the specific strains of Shiitake you utilize. Please provide your current lead times from order to delivery and an estimate of shipping costs or freight options available to our facility near North Salt Lake City, Utah. Your prompt response will be greatly appreciated!
