Usage
必需 is often confused with 必须 (bìxū, must/have to), but they differ: 必需 describes things that are necessary (adjective), while 必须 expresses obligation or requirement (modal verb). 必需 typically appears before nouns (必需品 = necessities) or in patterns like '对...是必需的' (is necessary for...). It's more formal than everyday speech.
