Final Order Cutoff's (FOC) Explained

This is the definition of FOC and OIC via Diamond Comic Distributors:

Final Order Cut-Off (FOC) Date

This is the date -- normally a Monday, except under special circumstances like holidays -- on which some Vendors commit to a print/production run for a title/product. Initial Orders and Reorders for items carrying an FOC date may be increased or decreased by this date. FOC dates are subject to change; such changes (and subsequent adjustments to the affected item's ship date) are regularly announced in all Diamond publications.

LOCAL COMIC SHOPS may adjust orders for all items from participating Vendors on the Final Order Cut-Off section of the Retailer Services Website’s FOC Weekly Adjust or Monthly Adjust pages in the Orders section. Premier Vendor titles are color-coded by publisher (DC=blue, Dark Horse=grey, IDW=red, Image=gold, Marvel=yellow, Other publishers=green) for easy reference.

The deadline for placing FOC orders via the Diamond website is Monday by 10:00 p.m. Eastern Time. LOCAL COMIC SHOPS also have the option of placing FOC orders with their Diamond Customer Service Representative by Monday at 5:00 p.m. Eastern Time.

Order Increase Cut-Off (OIC) Date

Specific dates – printed in each issue of the PREVIEWS Retailer Order Form next to items from vendors (such as BOOM! Entertainment, Dynamite Entertainment, etc.) – by which LOCAL COMIC SHOPS can submit Order Increases to Diamond and be virtually guaranteed that the additional quantities will ship with your Initial Orders. It differs from the Final Order Cut-Off (FOC) Date in that you may not decrease or cancel your orders for OIC-dated items.
