进出口参考工具
HS 编码参考查询
输入编码（如 8518 或 8518.30.20.00）或英文商品名，查看官方税则描述与编码层级；一个描述命中多个候选分类时会全部列出，由你或报关行对照商品材质、用途等细节判断。
参考查询不等于海关归类裁定；页面税率为美国进口税率参考，不是进口到中国或其他国家应缴的税率。
数字（带点不带点都行）按编码前缀查；文字按官方英文描述查。数据只有英文——输中文会明确提示，不会替你猜码。

常见问题
这个查到的编码能直接拿去报关吗？
不能。这里是参考查询：候选编码、官方描述和层级仅供参考，不等于海关归类裁定。正式归类要按归类总规则对照商品材质、成分、用途和加工程度，必要时向海关申请预归类裁定。
为什么一个商品名会搜出好几个编码？
正常现象。同一描述在不同层级（税目/子目/统计后缀）和不同类目下都可能出现——比如 cotton 在纱线、织物、服装各章都有条目。工具列出全部候选，不会替你猜唯一答案。
页面上 8 位、10 位编码是哪国的？
国际 HS 只统一前六位（章 2 位 + 税目 4 位 + 子目 6 位）。这里的 8 位/10 位是美国 HTS 的国家扩展编码，已明确标注；中国用 8 位税则号列，欧盟用 8 位 CN 码，都不在本数据里。
显示的税率是到中国要交的关税吗？
不是。税率列是美国进口税（General 最惠国 / Special 协定 / Column 2），只适用于向美国进口，仅供横向参考；进口到中国或其他国家的税率要去对应官方渠道查询。
中文搜的结果准确吗？
中文词按《2026 年进出口税则》官方中文品名逐字匹配，不机翻、不猜码；命中的是官方文本里出现过的名称。口语化叫法可能匹配不到，换更正式的品名或英文名再试。
数据多久更新一次？
数据快照来自美国 USITC 发布的 2026 HTS Revision 22（2026-10-30 生效），页面会显示版本和生效日期；版本过旧时会有提示。正式申报请以官方实时查询为准。
