Yes, there is a time limit for sending samples through Temu. Generally speaking, samples should be used as soon as possible after they are sent out to avoid sample expiration. Especially for some samples that are susceptible to oxidation, photolysis or biodegradation, they should be used within the specified time.

In addition, the storage conditions of the samples will also affect the time limit for sending samples, and they should be stored according to the storage requirements of different samples. If there are special needs, you can also contact the mailing company to arrange expedited delivery, but this may incur additional fees.
