  • 禁止寄遞物品指導目錄(國郵發〔2016〕107 號):19 類 188 種禁寄物品,集運高風險者:第 4 類壓縮和液化氣體(含打火機)、第 5 類易燃液體(含酒精成分香水、指甲油、油漆)、第 12 類毒品及易製毒化學品、第 16 類侵犯智慧財產權和假冒偽劣物品(盜版品、假藥)、第 17 類瀕危野生動植物及其製品(象牙、虎骨)。另《快遞暫行條例》(國務院令第 806 號,2025-06-01 施行)要求實名收寄、收寄驗視與安全檢查。(國家郵政局 / 公安部 / 國家安全部)

This column maps China's export control categories by the first 6 digits of the HS code and is for reference only. China's customs commodity codes have 10 digits, and from the 7th digit onward they do not correspond to Taiwan's tariff numbers. China also states officially that “the scope of goods is determined by the goods description; customs commodity codes are provided as a reference for customs declaration”, and for dual-use items that “a licence must be obtained as required by law whether or not a customs commodity code is listed”, so whether goods may be exported cannot be judged by the code alone. Some control measures are currently suspended; actual export rules are subject to China's latest official announcements.

2026 官方兩用物項目錄:HS6 854320 共 1 項候選

商品範圍以官方品名與描述為準;中國10位海關商品編號僅供通關申報參考。台灣與中國只共用前6位HS,卡片關聯均屬候選提示。

  • 3A230 高速脉冲发生器及其脉冲头;中國商品編號 8543209010;具有以下两种特性的高速脉冲发生器及其“脉冲头”: a.在小于55Ω电阻负载上的输出电压大于6V; b.“脉冲转换时间”小于500ps。 技术说明: 1.在3A230.b项中,“脉冲转换时间”是指电压幅 度从10%增至90%时的时间间隔。 2.“脉冲头”是指为接受电压阶跃函数并使之形成 可包括矩形脉冲、三角形脉冲、阶跃脉冲、冲击脉冲、指 数脉冲或单周期脉冲等各类脉冲形式而设计的脉冲形成 网络。“脉冲头”可以是脉冲发生器的一个整体组成部分 或该装置的一个插件模块,也可以是一个外部连接装置。

官方海關商品編號欄空白者仍可能依法須辦兩用物項許可;不得自行猜配稅則號別。
