锡矿/锡精矿进口报关清关全流程｜广州埔江国际 Guangzhou Pujiang International TradingCo., Ltd.

口岸：广州南沙、黄埔；深圳盐田、蛇口（吨袋矿粉集装箱进口）

HS编码：2609000000 锡矿砂及其精矿 Tin ores andconcentrates监管条件：7A = 自动进口许可证O证 +入境法定检验检疫（一票一证，必须船前办好；仅实验室小样≤50kg豁免O证）税费：惠国关税0%；进口增值税13%（CIF完税价，进项可抵扣） ✅ 国别关税差异（重点）

English: Apply for Automatic Import License (O-License) beforeshipment. Contract specifies DMT pricing, moisture deduction,processing charge, radioactivity & hazardous element limit. Formulapricing contract needs pre-filing with customs. Pre-shipmentinspection, no tailings or garbage mixed in cargo.

2. 海外装船 & 海运订舱 Ocean Booking & Loading

4. 报检 + 单一窗口申报 Inspection & Customs Declaration

1）入境法定检验检疫（强制）：现场γ放射性扫描、固废筛查、有害元素检测；指标异常直接取样实验室检测；放射性/有害元素超标一票否决退运2）单一窗口申报，上传全套单证+O证；按干吨DMT核算完税价格，水分予以扣减；伴生金银价值必须如实申报3）海关审价：参考LME/沪锡价格、合同、付汇凭证；线上缴纳增值税

English: Mandatory including radioactivity scanning,solid waste screening and hazardous element test. Customs valuationon DMT basis, deduct moisture, declare Au & Ag value. Pay VAT viasingle window.

5. 海关查验 Customs Examination

随机布控H986机检或人工开箱查验，核对吨袋包装、重量、外观杂物、放射性复测；怀疑固废/有害元素超标，取样送实验室鉴别。

English: H986 scanning or physical inspection. Sampling for labtest if suspected solid waste or element over-limit. Non-compliantcargo will be returned overseas.

6. 放行 → 拖车提柜 → 堆场仓储 Release → Trucking → Warehousing

放行后码头提柜，安排20GP/40HQ矿柜拖车直达冶炼厂/矿石堆场；拆柜、过磅、取样、堆存、分拨。

English: After customs release, container pickup, inlandtrucking, devanning, weighing, sampling & ore yard warehousing.

二、全套清关资料 Document Checklist（中英文对照）

✅ 基础商业文件 Basic Commercial Docs

1. Sales Contract 贸易合同（注明DMT、水分扣重、加工费、公式定价）

2. Commercial Invoice 商业发票（Sn品位、水分、伴生金属、DMT）

3. Packing List 装箱单/重量单

4. Bill of Lading (B/L) 海运提单

5. Certificate of Origin 原产地证：东盟RCEP FORM-E；非洲/南美对应产地证

✅ 锡精矿专项文件 Mine-Specific Documents

1. Automatic Import License（O证）自动进口许可证【强制必备】

2. Certificate of Analysis 成分分析证书（Sn、As、Pb、Cd、Hg、水分、伴生金银）

3. Radioactivity Test Report 放射性检测报告（重点：缅甸、非洲矿）

4. 报关报检委托书 Authorization Letter for Customs Declaration

5. 企业营业执照、海关注册备案资料

6. 公式定价备案回执（点价/长协浮动定价合同必备）

7. Non-solid waste declaration 非固体废物符合性声明

三、不同产地锡矿专项风险提示（Key Risk Reminder）

东南亚（缅甸 / 泰国 / 越南 / 马来西亚）

1. 缅甸锡矿：大风险：伴生铀钍放射性超标，很多矿到港放射检测直接退运；其次杂质波动大，砷铅不稳定；RCEP产地证注意真实原产地，不能转口造假

2. 泰国、越南、马来西亚锡精矿：指标普遍稳定，放射性风险偏低；但注意区分锡精矿与锡矿砂，低品位矿容易触发固废鉴别

非洲（刚果金、卢旺达等）

1. 远洋船期长，单证流转慢，建议提前2周预审全套资料

2. 放射性、砷超标高发；部分矿区矿泥、尾矿混杂，固废鉴别风险高

3. 产地证、出口文件容易不规范，到港后无法享惠

南美（玻利维亚、巴西、秘鲁）

1. 主要风险：砷、铅有害元素超标；部分矿品位波动大

2. 远洋运输，注意吨袋防潮，水分超标会扣重，影响完税价格

3. 原产地文件办理周期较长，提前安排

English:

1. Myanmar tin concentrate: High risk of U/Th radioactivityover-limit.

2. Africa: Long transit time, high radioactivity & impurity risk,easy mixing with tailings.

3. South America: Main risk is high As & Pb content, moisturecontrol needed.

4. Any cargo with excessive radioactivity, hazardous elements ormixed waste will be returned. Missing O-License will lead todeclaration failure and heavy port surcharge.
