What time definite means
Time definite services commit to delivering by a set day, or by a set time or window on that day, agreed before the shipment moves. Instead of an estimate, the shipper and provider agree when the freight will arrive, such as by end of day Thursday or by 10 a.m. tomorrow. This page explains the general freight term, not any company with that name.
More broadly, freight services move goods from the businesses that make or sell them to the businesses and people that use them, by truck, aircraft or both. Time definite is one way of choosing how that move is planned: around a fixed arrival rather than the fastest possible one or the cheapest route.
