🏭 Granulated Iron Slag (Iron Slag)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition and Classification: What is "Granulated Iron Slag"?
Granulated iron slag is a by-product of steelmaking processes, specifically the non-metallic material separated from molten iron or steel. When the molten slag is rapidly quenched with water or steam, it forms granulated slag (also known as blast furnace slag or steel slag granules).
In international trade, this product is broadly categorized under Chapter 26 (Ores, slag and ash). The key distinction lies in its source: 1. Municipal Waste Incineration Ash: Ash/residue from burning household/urban waste. 2. Industrial Slag/Ash: Slag from metallurgical processes (iron/steel) or other industrial incineration.
⚠️ Critical Distinction:
- If the material is slag/ash from metallurgical processes (e.g., blast furnace, electric arc furnace) → It is NOT municipal waste incineration ash.
- If the material is slag/ash from incinerating municipal waste → It falls under 2621.10.00.00.
- Granulated Iron Slag typically falls under 2621.90.00.00 ("Other") because it is industrial slag, not municipal waste ash.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Classification Logic |
|---|---|---|---|
2621.10.00.00 |
Ash and residues from the incineration of municipal waste | Ash from city waste-to-energy plants | ❌ Not Applicable to Iron Slag |
2621.90.00.00 |
Other slag and ash (including seaweed ash) | Iron slag, steel slag, blast furnace slag, granulated slag | ✅ Correct for Granulated Iron Slag |
🔍 Key Reminder:
- Granulated Iron Slag is NOT "municipal waste ash." It is an industrial by-product of metal smelting.
- Therefore, it must be classified under 2621.90.00.00 ("Other"), NOT 2621.10.00.00.
- Misclassification as2621.10.00.00could lead to incorrect tariff application (see below).
💰 III. 2026 Latest Tariff Rate Details (Including Additional Taxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)
🎯 1. 2621.90.00.00 —— Other slag and ash (Including Granulated Iron Slag)
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (ad valorem) |
| USITC Additional Tariff | +25.0% (Under USITC Footnote 9903.88.01) |
| IEEPA Additional Tariff | +7.5% (Note: See explanation below for 25% vs 7.5%) |
| Total Tax Rate | 25.0% |
| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Available (deny_de_minimis) |
| Legal Basis Path | IEEPA:9903.01.25 → IEEPA:9903.01.24 → USITC:2621.90.00.00 → FOOTNOTE:9903.88.01 |
📌 Explanation:
- The USITC Additional Tariff of 25% applies to most industrial slags and ashes under 2621.90.00.00.
- Note on IEEPA Tax: According to the provided data, the tax detail for2621.90.00.00is "Base: 0.0%, Additional: 25.0%", totaling 25.0%. This implies that the total additional tariff (including any IEEPA components) is already 25% for this code under the current rules for Chinese origin.
- Contrast with 2621.10.00.00: That code has a total tax of 7.5% (Base 0% + Additional 7.5%).
- Conclusion: Granulated Iron Slag (industrial) is taxed at 25%, NOT 7.5%. The 7.5% rate is for municipal waste ash, which is a different product.⚠️ Critical Warning:
- Do NOT misclassify granulated iron slag as2621.10.00.00to save 17.5% (25% - 7.5%).
- Customs authorities will verify the source of the slag. If it is steel/iron slag, it must be2621.90.00.00.
- Misclassification can result in back taxes, penalties, and shipment delays.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Must Provide | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state: "Granulated Iron Slag," "Blast Furnace Slag," or "Steel Slag." |
| ✅ Certificate of Origin | ✔️ | To confirm Chinese origin and apply correct tariffs. |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Proves the material is non-hazardous (if applicable) and confirms composition. |
| ✅ Bill of Lading | ✔️ | Must match the HS Code 2621.90.00.00 and description. |
| ✅ Commercial Invoice | ✔️ | Clearly describe as "Granulated Iron Slag for Industrial Use," NOT "Municipal Waste Ash." |
| ✅ Test Report | ✔️ | Chemical composition analysis (e.g., CaO, SiO2, MgO content) to prove it is metallurgical slag. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Industrial Slag = 2621.90 (25%), Municipal Ash = 2621.10 (7.5%)! Do Not Mix!"
| Scenario | Correct HS Code | Incorrect HS Code | Consequence |
|---|---|---|---|
| Granulated Iron Slag (from steel mill) | 2621.90.00.00 |
2621.10.00.00 |
25% Tax vs 7.5% → Underpayment Penalty! |
| Ash from Waste-to-Energy Plant | 2621.10.00.00 |
2621.90.00.00 |
Overpayment, but less risk than misdeclaration |
| Seaweed Ash (Kelp) | 2621.90.00.00 |
2621.10.00.00 |
Correct if declared as "Other" |
| Mixed Waste Slag | Varies | High Risk | Requires detailed source documentation |
✅ 3. Special Cases Handling
| Scenario | Handling Advice |
|---|---|
| Granulated Slag Used for Cement | Declare as raw material for cement production. Provide end-use declaration if applicable. |
| Slag Containing Heavy Metals | Ensure MSDS confirms non-hazardous status. If hazardous, different HS Code and EPA regulations may apply. |
| Blast Furnace Slag vs. Electric Arc Furnace Slag | Both are 2621.90.00.00. No difference in tariff, but specify in documentation to avoid confusion. |
| Import for Construction (Aggregate) | Still 2621.90.00.00. No special duty reduction for construction use unless specified by other laws. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification Requirements | Notes |

| 🇬🇧 United Kingdom | 2621.90.00.00 |
0% | UK REACH | Post-Brexit, aligned with EU standards. |
| 🇦🇺 Australia | 2621.90.00.00 |
5% | None | Moderate tariff. |
| 🇯🇵 Japan | 2621.90.00.00 |
0% | JIS Standard | Often duty-free for industrial use. |
📌 Conclusion:
- US Market: 25% tariff is a significant cost. Ensure accurate classification to avoid penalties.
- Other Markets: Mostly 0% or low tariffs. US is the only market with the high additional tariff for this category.
📌 VI. Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Declaring "Granulated Iron Slag" as "Municipal Waste Ash" (2621.10.00.00) to pay 7.5% instead of 25%.
👉 Consequence: Customs will reject based on MSDS and product description. Back taxes + 25% penalty for underpayment.
❌ Error 2: Providing only a generic "Slag" description without specifying "Iron/Steel" or "Granulated."
👉 Consequence: Customs may classify under a default "Other" code with higher scrutiny or additional duties.
❌ Error 3: Ignoring MSDS for granulated slag.
👉 Consequence: If slag is considered hazardous due to heavy metals, it may require EPA approval and different HS Code.
✅ Correct Practice:
"Granulated Iron Slag, Blast Furnace By-product, Non-Hazardous, Chemical Composition: CaO 40%, SiO2 35%, for Industrial Aggregates, Origin: China"
🎯 VII. Conclusion: Precise Classification Saves Money!
🎯 Remember the Rule:
🔹 "Iron Slag = Industrial = 2621.90 (25%)"
🔹 "Municipal Ash = Waste = 2621.10 (7.5%)"
🔹 "Do Not Confuse! 17.5% Difference is Too High!"
📌 Tip:
If your granulated iron slag is produced in Vietnam, Thailand, or Malaysia, you may still be subject to US tariffs if the substantial transformation did not occur in those countries. Chinese origin triggers the 25% duty.
📣 Immediate Action:
📞 Confirm Origin: Ensure your supplier provides a Certificate of Origin.
📄 Prepare MSDS: Obtain a non-hazardous MSDS to prove it is industrial slag, not municipal waste.
🚀 Declare Correctly: Use 2621.90.00.00 to avoid costly penalties.
✨ Professional Clearance Starts with Accurate Classification!
💼 Your Cost Control Depends on Correct HS Code!

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
