限定品 is a broader term for any limited-edition or exclusive item, while 期間限定品 specifically emphasizes a time-limited availability.
Compound of 期間 (period) + 限定 (limited) + 品 (product). The exact historical derivation is uncertain, but the word follows a common pattern for describing time-limited goods.
