钨矿、锡矿、钨锡混合矿/锡钨精矿进口清关全流程（广州黄埔/南沙、深圳盐田/蛇口，含白云/宝安机场空运、快递矿样）

服务方：广州埔江国际 Guangzhou Pujiang International

HS编码与监管区分（核心，钨属于战略管控矿，和锡监管差异极大）

1. 钨矿砂及其精矿（黑钨、白钨、钨精粉，含钨锡混合精矿，钨为主）：2611000000监管条件：3（两用物项进口许可证）+7（自动进口许可证O证）+A（入境法定检验检疫）✅重点：钨矿（含钨矿样），无论重量、货值大小，哪怕几十克化验小样，必须同时具备【两用物项进口许可证+O证】，无任何KJ3豁免，不能拆分包裹走快件简易申报

2. 锡矿砂及其精矿（锡精矿，锡为主）：2609000000监管条件：7（O证自动进口许可证）+A（入境法检）✅锡矿不需要两用物项证；商用批量必须O证；锡矿小样同样不适用KJ3简易通道，只能走3010货样广告品/0110一般贸易，需要O证

税率：惠国关税0%；进口增值税13%，CIF为计税基数，一般纳税人可抵扣；RCEPFORM-E原产地证可享受协定零关税。

一、发货前前置准备（海外装船/装机前，证必须提前办好，货到不能补办）

1. 国内企业资质

1）进出口经营权、海关注册10位编码 2）钨矿：双证办理

两用物项和技术进口许可证：商务部机电办审批，一批一证，周期长（15–30工作日）

自动进口许可证O证：商务部电子证3）锡矿：仅O证（自动进口许可证），5–7工作日，非一批一证

无进出口权，可做双抬头代理进口，埔江协助代办两类许可证；钨证审批周期远长于铜铅锌锡，务必预留充足时间。

2. 全套单证清单

商业文件外贸合同、商业发票（干基品位、水分、计价系数、点价条款；伴生有价金属W/Sn/Cu/Bi/Ag全部列明）、装箱单、海运提单/空运AWB、原产地证RCEPFORM-E

CNAS检测技术文件（海外发货前预检测）

1. 成分分析报告：主元素WO₃ / Sn，砷As、铅Pb、镉Cd、汞Hg、氟F有害杂质

   限值参考：As≤0.50%，Pb≤6.00%，Cd≤0.05%，Hg≤0.01%，F≤0.10%，超标直接布控退运

2. 放射性检测报告（GB20664）γ剂量率≤0.4μSv/h；钨锡矿普遍伴生U/Th，放射性是第一大口岸风险，非洲、南美、东南亚矿风险极高

3. 水分检测报告（湿重/干基，审价、固废判定）

4. MSDS：钨精矿、锡精矿粉末属于9类危险品UN3077，海运/空运粉末矿必须配套危包证

监管文件钨矿：两用物项进口许可证 +O证；锡矿：O证；报关委托书、报检委托书、情况说明；矿样需注明“实验室化验样品，不作销售”。

3. 固废判定红线（一票否决）

钨精矿：WO₃≥65%；WO₃过低，大量废石泥土，海关启动固废鉴别，判定尾矿直接退运

锡精矿：干基Sn≥40%（YS/T339国标）；Sn＜40%极易触发固废鉴别，低度锡尾矿禁止进口

钨锡矿执行先放后检：门式放射性+外观筛查合格可先行提货；后续实验室检测不合格，海关有权召回、处置、退运。

二、海运（广州/深圳港口）完整清关流程

1. 海外取样预检测，确认品位、有害元素、放射性达标再装船船舶到港前3–5天，埔江预审全套单证，单一窗口预录入，录入许可证号、品位、点价作价资料。

2. 船舶到港，换单凭正本/电放提单换D/O提货单，支付换单费、DOC文件费。

3. 入境法检申报（A证）+门式放射性筛查码头通道放射性扫描，外观排查泥土、外来夹杂物；初筛异常，货物隔离，取样做放射性复测+固废鉴别。

4. 单一窗口报关申报（0110一般贸易）钨锡混合精矿，按主含量归类：钨＞锡归入2611，锡＞钨归入2609，禁止混报两个HS；点价贸易，全套作价、LME计价资料完整留存，审价严格，低报货值触发估价、稽查。

5. 税费缴纳关税0%，进口增值税13%；AEO企业可汇总征税、关税保证保险。

6. 海关查验+多点分层取样化验H986机检，随机人工开箱；放射性、有害元素、固废属性为必检项目。

7. 检验检疫合格，出具《入境货物检验检疫证明》拿到证书后方可入厂冶炼、销售。

8. 码头提柜/散货卸货，内陆密闭拖车配送埔江安排提货、堆场堆存；可配套保税仓储，暂缓缴税。

三、空运/国际快递（白云CAN、宝安SZX机场）钨锡矿/矿样清关

机场放射性筛查比海港严苛；钨锡矿粉末航空承运难度极高，优先块状样品；钨矿无论样品大小，快件渠道也必须双证，严禁KJ3简易申报

1. 空运普货（吨级商用钨/锡精矿，0110一般贸易）流程同海运；航班落地货站换单、门式放射性筛查、单一窗口申报、缴税、查验、放行；机场仓租昂贵，免费堆存期很短，单证必须提前预审。

2. 国际快递DHL/FedEx（化验矿样）

钨矿样品：无论重量货值，必须两用物项证+O证，走3010货样广告品或0110一般贸易，禁止KJ3

锡矿样品：必须O证，走3010货样广告品/0110，不适用KJ3

红线：不能拆分多包裹、分多票快件，规避许可证监管，属于违规，直接扣货+稽查处罚

四、广州/深圳口岸清关费用参考（不含国际海/空运费，2026市场参考）

费用项目广州（南沙/黄埔）深圳（盐田/蛇口）备注海运报关代理费1200–2000元/票1200–2000元/票钨矿因双证，代理费高于普通铜铅锌矿；单证预审、申报、查验陪同、审价应对空运普货报关代理费1500–2200元/票1500–2300元/票吨级矿空运，含危品资料、两用物项证资料审核快递矿样正式报关代理800–1400元/票850–1500元/票钨锡矿样品，无KJ3通道，全部正式申报换单费（海运/空运抽单）300–600元/票300–500元/票船公司/航司收取THC码头操作费按柜型/散货吨价按柜型/散货吨价散货另计码头装卸费放射性+成分检测费2000–4500元/批2000–4500元/批CNAS实验室；固废鉴别单独计费海关查验费1000–4500元/次1000–4500元/次抽中查验才收取，掏箱、吊装、防尘防护、取样港口堆存费0.6–1.8元/吨/天0.6–1.8元/吨/天短期免费堆存，超期柜租另计机场仓储费80元/m³/天65元/m³/天免费期短，滞仓成本上升极快珠三角内陆拖车费900–1600元/柜800–1500元/柜散货陆运按吨计价

许可证代办：O证官方免费；两用物项进口许可证代办服务费另计，周期15–30工作日。

五、核心风险红线（钨锡矿监管远严于铜铅锌）

1. 钨矿缺两用物项证=无证进口：商用货、矿样，缺证直接扣货、行政处罚，无法后期补办。

2. 固废鉴别：品位不足、夹带大量泥土废石，判定固废直接退运，巨额滞港、堆存费。

3. 放射性超标γ＞0.4μSv/h，一票否决，整批退运；钨锡伴生放射性风险远高于普通铜矿铅锌矿。

4. 有害元素超标砷、铅、镉、汞、氟超标，整批退运。

5. 归类错误钨锡混合精矿，未按主金属归类，HS申报错误，触发改单、估价、稽查。

6. 快件通道违规：钨锡矿样品不能走KJ3简易快件，拆分包裹规避许可证属于违规。

7. 粉末矿包装：钨锡精矿粉属于9类危险品，包装破损漏粉，码头/航司拒载、拒绝卸货。

8. 申报时限：运输工具进境起14日内申报，超期产生滞报金。

Import & Customs Clearance for Tungsten Ore, Tin Ore,Tungsten-Tin Ore & Concentrate

Service Provider: Guangzhou PujiangInternational

HS Code & Regulation

1. Tungsten ore & concentrate (W-bearing mixed concentrate,tungsten as main component): 2611000000Control:3 (Dual-use item import license) +7 (Automatic ImportO-License)+A (Mandatory Entry Inspection)✅ Critical: Fortungsten ore (including lab samples), dual-use license +O-license are mandatory regardless of weight & value. KJ3simplified express channel is prohibited, parcel splitting to evadepermit is not allowed.

2. Tin ore & concentrate: 2609000000Control:7(O-License)+A (Mandatory Entry Inspection)✅ Tinore does not require dual-use permit. Commercialbulk shipment must hold O-License. Tin samples also cannot use KJ3,must be declared under 3010 sample or 0110 general trade with validO-License.

Tariff: MFN duty 0%; Import VAT 13%, calculatedon CIF value, deductible for general VAT taxpayers. RCEP FORM-Ecertificate for preferential zero tariff.

1. Pre-shipment Preparation

1.1ualification

1. Import & export right, customs registration (10-digit customscode).

2. Tungsten: Two permits

Dual-use item import license: MOFCOM,one-batch-one-cert, lead time 15–30 workingdays

Automatic Import O-License: MOFCOM electronic license

1. Tin: Only O-License, 5–7 working days,non-one-batch-one-cert

   Importers without import/export right can use dual-title agencyimport. Pujiang can assist permit application. Tungsten permitapproval takes much longer than Cu/Pb/Zn/Sn.

1.2 Mandatory Document List

Commercial DocumentsSales Contract, CommercialInvoice (state dry grade, moisture, pricing coefficient, formulapricing; list all associated metals W/Sn/Cu/Bi/Ag), Packing List,Ocean B/L / Air Waybill, Certificate of Origin (RCEP FORM-E).

CNAS Lab Test Documents (pre-test before shipmentoverseas)

1. Assay report: WO₃ / Sn main grade, As, Pb, Cd, Hg, F hazardousimpurities

   Reference limits: As≤0.50%, Pb≤6.00%, Cd≤0.05%, Hg≤0.01%,F≤0.10%. Cargo will be returned once exceeded.

2. Radioactivity report (GB20664): Gamma dose rate ≤0.4μSv/h.Tungsten-tin ore often contains U/Th, high radioactivity risk fromAfrica, South America & Southeast Asia.

3. Moisture test report (wet/dry base, core for valuation & solidwaste judgement)

4. MSDS: Tungsten & tin concentrate powder is Class9 UN3077dangerous goods, dangerous goods packaging certificate mandatoryfor sea/air shipment.

Regulatory DocumentsTungsten: Dual-use importlicense + O-License. Tin: O-License. Customs POA, Inspection POA,statement letter. For samples, state “for laboratory test only, notfor sale”.

1.3 Solid Waste Threshold (Non-negotiable)

Tungsten concentrate: WO₃≥65%. Low WO₃ with excessive rock/soiltriggers solid waste identification and forced return.

Tin concentrate: Dry Sn≥40% (YS/T339). Tin concentrate Sn＜40%will easily trigger solid waste appraisal, low-grade tin tailingsare prohibited for import.

Customs policy: Tungsten & tin ore adopts release beforelab test. Cargo can be released after passing on-siteradioactivity & visual screening. If final lab test fails, customsmay order recall or return.

2. Sea Freight Clearance Process (Guangzhou / ShenzhenPorts)

1. Overseas sampling & pre-testing before loading. Pujiangpre-audits documents 3–5 days before vessel arrival, pre-submitdata on Single Window, fill permit number, grade & pricingdocuments.

2. Vessel arrival & document exchange: Exchange Delivery Order(D/O) against original or telex B/L, pay document fee.

3. Statutory inspection (A certificate) + portal radioactivityscanning. Visual check for soil and foreign debris. Failed initialscreening → isolation & sampling for radioactivity re-test & solidwaste appraisal.

4. Customs declaration via Single Window (0110 General Trade).Mixed tungsten-tin concentrate shall be classified by dominantmetal: W＞Sn → 2611; Sn＞W → 2609. Mixed HS declaration is forbidden.Complete formula pricing documents are mandatory. Under-declaredvalue triggers re-valuation and anti-smuggling audit.

5. Tax payment: Customs duty 0%, import VAT 13%. AEO enterprise canapply aggregate tax payment or customs duty insurance.

6. Customs physical inspection & multi-point sampling. H986 X-rayscan, manual unpacking. Radioactivity, hazardous elements and solidwaste screening are mandatory.

7. Issue Entry Inspection & Certificate after passingtest, required for smelting & domestic sale.

8. Container pickup / bulk discharge & inland sealed trucking.Pujiang arranges terminal handling, bonded warehouse available fordeferred tax.

3. Air / Express Import (Baiyun / Bao’an Airport) for Tungsten& Tin Ore / Samples

Airport radioactivity screening stricter than seaports. Powderconcentrate has strict airline restrictions, block samplespreferred. For tungsten samples, dual-use license +O-license required even for small lab samples, KJ3 is notallowed.

1. Air cargo (commercial bulk ore, 0110 General Trade) Sameworkflow as sea import. After flight arrival, document exchange,portal radioactivity scan, Single Window declaration, tax payment,inspection & release. Airport storage cost high with short freeperiod, pre-document review is essential.

2. International Express (DHL/FedEx lab samples)

Tungsten sample: Dual-use permit + O-license required, declareunder 3010 sample or 0110 general trade, KJ3 forbidden.

Tin sample: O-license required, 3010 /0110 declaration, KJ3 notavailable.

Important warning: Do not split commercial shipments intomultiple parcels to bypass permit re, this will triggercustoms detention and penalty.

4. Reference Clearance Cost (Guangzhou & Shenzhen, excludeocean/air freight, 2026 market)

Permit application: O-license official fee zero; dual-use importpermit agency service fee separate, lead time 15–30 workingdays.

5. Key Risk Reminders

1. Import without permit for tungsten: Cargodetained and penalized, permit cannot be applied after cargoarrival.

2. Solid waste identification: Low grade withexcessive rock/soil will be identified as solid waste and forced toreturn, resulting in heavy detention cost.

3. Radioactivity non-compliance: Gamma doserate＞0.4μSv/h → forced return. Tungsten-tin ore has higher naturalradioactivity risk than Cu/Pb/Zn ore.

4. Hazardous element over-limit: As, Pb, Cd, Hg, Fexceeding standard → return.

5. Misclassification: Mixed tungsten-tinconcentrate must be declared by dominant metal, wrong HS leads toamendment, valuation and audit.

6. Express channel violation: KJ3 is not allowedfor W/Sn samples, parcel splitting to evade permits is illegal.

7. Powder packaging: Tungsten & tin concentratepowder is Class9 dangerous goods. Leakage will be rejected byterminal or airline.

8. Declaration deadline: File customs declarationwithin 14 days after transport arrival, latedeclaration surcharge applies.

钨锡矿监管门槛高，许可证、放射性、固废鉴别都是重点卡点，工作任务模式可以帮你做单证核对、方案对比和风险清单梳理，要不要用它处理？
