Use 「需要」 for demand for goods or general need; it pairs with 「供給」 in economics. To ask things of someone, use 「要求」 or the milder 「要望」, formal 「要請」, or 「請求」 when claiming a right. For ordering goods, 「注文」 (honorific 「ご用命」) fits; 「入り用」 covers personal needs, 「リクエスト」 casual requests, and 「希求」「所望」 are written-style wishes.
