captive consumption是什麼意思?

題目：

captive consumption是什麼意思?
在國際貿易中用到的,怎麼翻譯?

解答：

我遇到過 受制生產 Captive Production
所以我想應該是 限制性消費品 吧
應該指某國對一些商品爲控制其供求平衡而採取種種進出口管制政策
給你個參考 We are interested in buying Copper rods of 8mm thickness (Dia) of electrode grade (99.89%) for our captive consumption.Our intial requirements would be in the range of 50 to 100 tons per month.
We are located at Mumbai,India Please Send us your product details and terms and consitions and the price (CIF Mumbai if possible)quotations of the above mentioned product.Looking forward for a mutually beneficial long-term relationship.Regards
