I received my shipment and it is marked PARTIAL. What does that mean?

Partial shipping means that we are shipping the oligos you ordered to you as they are completed, rather than our default method of waiting to ship until the order is complete, with all of the oligos shipping at the same time. We make every effort to synthesize and ship your oligos as quickly as possible because we know that they are time sensitive. On occasion one or more oligo may become delayed, e.g., because they did not pass one of our quality control checks or their processing took longer than anticipated. In these cases we can ship you a partial order at your request. You can also choose to have your order ship partial if you know some of your oligos will take longer than others (because of purification, etc.)—such requests will incur an extra shipping charge. If you would like to set an order to ship partial, you can request it at the time of checkout or by contacting IDT Customer Care at
