In economics, nondurables are the products consumers buy that aren't long-lasting. Things like fresh food and gasoline are considered nondurables.
Nondurables is short for nondurable goods, a category economists use to distinguish between products that are used right away and those, like a car or refrigerator, that last a long time. Nondurables are things that are consumed or used within a couple of years, including sunblock, tea, laundry detergent, pet food, and clothing. Durable comes from the Latin durabilis, "permanent," and nondurables adds the prefix non-, "not."
