印尼锡矿下游产业结构仍面临根本性挑战。尽管印尼锡产能庞大且产品在全球市场声誉卓著，但国内需求却极为有限。印尼锡出口商协会（AETI）数据显示，国内锡消费量仅占全国总产量的5%至7%，意味着印尼锡产品仍高度依赖出口市场。
AETI主席Harwendro Adityo Dewanto指出，这一状况表明矿产下游议程尚未伴随完善的下游产业生态发展，未真正构建起国内供应链，尤其是以锡为核心原料的制造业领域。他认为，锡衍生产品产业投资不足，与电子、化工、焊料、电镀及各类稳定用锡的制造组件等中间产业尚未发展密切相关。
“缺乏坚实的下游产业基础，国内锡衍生产品开发竞争力不及出口半成品。”他于2026年3月3日表示。Harwendro强调，尽管国内市场暂无法消化产能，印尼锡在全球市场仍占据强势地位，产品纯度达99.9%，是全球最受青睐..
