🏗️ Ground Slag Cement Clinker
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Import Strategy
📌 One, Product Definition & Classification: What Exactly Is "Ground Slag Cement Clinker"?
Ground Slag Cement Clinker is a hydraulic cement precursor produced by grinding granulated blast furnace slag (a byproduct of iron and steel manufacturing) with small amounts of Portland cement or gypsum. It is not a finished cement product but rather a raw or semi-finished material used in the production of slag cement (also known as ground granulated blast-furnace slag cement or GGBS cement).
⚠️ Key Distinction:
- If it's pure clinker (i.e., the sintered product of slag and cement raw materials), not yet ground, it may fall under 2523.10.00.00.
- If it's already ground and used as a cementitious material, it falls under 2523.90.00.00 (other hydraulic cements).
- Do NOT confuse it with "granulated slag" (2618.00.00.00) — that’s raw slag, not clinker.
📦 Two, HS Code Classification Details (2026 Latest Tariff Authority Match)
| HS Code | Product Description | Applicable Scenario | Is It Clinker? |
|---|---|---|---|
2523.10.00.00 |
Portland cement, aluminous cement, slag cement, supersulfate cement, and similar hydraulic cements, whether or not colored or in the form of clinkers: Cement clinkers | Raw or semi-finished clinker (e.g., sintered slag-cement mix) before final grinding | ✅ Yes — Clinker form |
2523.90.00.00 |
Portland cement, aluminous cement, slag cement, supersulfate cement, and similar hydraulic cements, whether or not colored or in the form of clinkers: Other hydraulic cements | Ground or processed cement (e.g., ground slag cement, ready-to-use cement) | ❌ No — Not clinker, already ground |
2618.00.00.00 |
Granulated slag (slag sand) from the manufacture of iron or steel | Raw slag from steelmaking, not sintered or clinkered | ❌ No — Raw slag, not clinker |
2619.00.30.00 |
Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel: Ferrous scale | Iron/steel mill waste (e.g., scale from rolling) | ❌ No — Waste product, not cement clinker |
2619.00.90.00 |
Slag, dross (other than granulated slag), scalings and other waste from the manufacture of iron or steel: Other | General waste slag, not used in cement | ❌ No — Industrial waste, not clinker |
🔍 Critical Point:
- Only if the product is in clinker form (sintered, granular, unground) and used in cement production →2523.10.00.00
- If it’s already ground and used as cement →2523.90.00.00
- If it’s raw slag (not sintered) →2618.00.00.00
💰 Three, 2026 Latest Tariff Rate Breakdown (With附加 Taxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (including subsequent imports)
🎯 1. 2523.10.00.00 — Cement Clinkers
| Item | Detail |
|---|---|
| Base Tariff | 0.0% (ad valorem) |
| USITC Additional Duty | +25.0% (under Section 301 of U.S. Trade Act) |
| IEEPA Additional Duty | +10.0% (International Emergency Economic Powers Act – applies to Chinese-origin goods) |
| Total Effective Tariff | 35.0% |
| Tax Calculation | CIF Value × 35.0% |
| De Minimis Threshold | ❌ Not applicable (denied de minimis) |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:2523.10.00.00 → FOOTNOTE:9903.88.01 |
📌 Explanation:
- The 25% USITC tariff comes from the Section 301 China Tariff List, targeting goods from China deemed to have unfair trade practices.
- The 10% IEEPA tariff is a national security-based levy under the IEEPA, applied to goods from China, Hong Kong, and Macau.
- Total: 35% — Significantly higher than standard tariffs, but lower than the 45% applied to fully processed cement (see below).
🎯 2. 2523.90.00.00 — Other Hydraulic Cements (Ground Slag Cement)
| Item | Detail |
|---|---|
| Base Tariff | 0.0% |
| USITC Additional Duty | +25.0% |
| IEEPA Additional Duty | +10.0% |
| Total Effective Tariff | 35.0% |
| Tax Calculation | CIF Value × 35.0% |
| De Minimis Threshold | ❌ Not applicable |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:2523.90.00.00 → FOOTNOTE:9903.88.01 |
📌 Important Note:
- Even though this is ground cement, it’s still subject to the same 35% total duty as clinker.
- The key factor is origin (China), not physical form.
- No difference in tax between clinker and ground cement — both are hit with 35% when imported from China.
🛠️ Four, Customs Clearance Practical Tips (Real-World Pro Tips)
✅ 1. Required Documentation (Must-Have List)
| Document | Required? | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clarify: form (clinker vs. ground), composition (slag %), origin, intended use |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | For handling, storage, and safety compliance |
| ✅ Commercial Invoice | ✔️ | Clearly state: “Ground Slag Cement Clinker” or “Slag Cement, Ground, in Bulk” |
| ✅ Bill of Lading / Air Waybill | ✔️ | Must match invoice |
| ✅ Certificate of Origin (CO) | ✔️ | If from China, must be stamped — otherwise, no tariff relief possible |
| ✅ Test Report (e.g., ASTM C989) | ✔️ | Proves it meets cement standards (helps avoid reclassification) |
| ✅ Packing List | ✔️ | Show weight, volume, packaging type (bagged, bulk, etc.) |
✅ 2.申报技巧 (Key Pro Tips)
🔥 “Clinker vs. Ground, Form Matters, Origin Rules All!”
| Scenario | Correct HS Code | Wrong Code | Risk |
|---|---|---|---|
| Raw clinker (unground, sintered) | 2523.10.00.00 |
2523.90.00.00 |
Higher tax if misclassified |
| Ground slag cement (ready for use) | 2523.90.00.00 |
2523.10.00.00 |
Higher tax if misclassified |
| Raw granulated slag (not clinkered) | 2618.00.00.00 |
2523.10.00.00 |
Severe penalties — not cement |
| Ferrous scale or waste slag | 2619.00.30.00 or 2619.00.90.00 |
2523.10.00.00 |
Detention, fines, or rejection |
✅ 3. Special Cases Handling
| Situation | Recommended Action |
|---|---|
| Clinker from Vietnam, Mexico, or India | Apply for IEEPA exemption — may qualify for 0% tariff if origin is not China |
| Clinker with 10% Portland cement + 90% slag | Still 2523.10.00.00 — as long as it's clinker |
| Clinker mixed with gypsum | Still 2523.10.00.00 — as long as not fully ground |
| Clinker used in specialty cement (e.g., low-heat, sulfate-resistant) | Still same HS code — no special treatment |
🌍 Five, Global Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 United States | 2523.10.00.00 or 2523.90.00.00 |
35.0% (China-origin) | None (but documentation required) | High risk — 35% tariff |
| 🇨🇳 China | 2523.10.00.00 |
5% | CCC, CE, ISO | No additional tariffs |
| 🇪🇺 European Union | 2523.10.00.00 |
0% (if CE-certified) | CE, REACH | No IEEPA/USITC tariffs |
| 🇦🇺 Australia | 2523.90.00.00 |
5% | RCM | No附加税 |
| 🇯🇵 Japan | 2523.90.00.00 |
0% | PSE | No附加税 |
📌 Conclusion:
- The U.S. is the only major market imposing a 35% tariff on Chinese-origin ground slag cement clinker.
- China, EU, Australia, Japan have much lower or zero tariffs — ideal for re-export or regional distribution.
📌 Six, Common Mistakes & Pitfalls (Learn from Others’ Errors)
❌ Mistake 1: Classifying raw granulated slag as cement clinker
👉 Result: Severe penalties, detention, or rejection — 2618.00.00.00 is not cement!
❌ Mistake 2: Using "slag cement" on invoice but shipping raw clinker
👉 Result: Misclassification, higher duty, delayed clearance
❌ Mistake 3: Not providing test reports or spec sheets
👉 Result: Customs may reclassify, demand additional fees, or hold shipment
❌ Mistake 4: Assuming "clinker" = "cement"
👉 Result: Wrong HS code, higher tax, compliance risk
✅ Correct Labeling Example:
"Ground Slag Cement Clinker, 90% GGBS, 10% Portland Cement, Sintered, Un-ground, in Bulk, Origin: China"
🎯 Seven, Final Verdict: Precision Pays Off!
🎯 Remember the Golden Rule:
🔹 "Clinker =
2523.10.00.00| Ground Cement =2523.90.00.00| Raw Slag =2618.00.00.00| Waste =2619.00.30.00"
🔹 Origin matters most — China = 35% tariff, others may be 0%
🔹 Never mix raw slag with cement clinker — it’s a red flag for customs
📌 Pro Tip:
If your product is originating from Vietnam, India, or Mexico, apply for IEEPA exemption — you may qualify for 0% tariff under U.S. trade policy.
Apply for Advance Ruling (Pre-Approval) — avoid disputes, delays, and overpayment.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
