What documentation is supplied with Avermectin impurities?

Do you publish prices or a lead time for Avermectin impurities?
No price list is published: quotations are prepared per enquiry, because availability and packing depend on the lot and the quantity you need. Send the catalogue number and the quantity and a technical contact will answer with availability and a quotation.
