ποΈ Granulated Blast Furnace Slag (GBFS)
π HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
π I. Product Definition & Classification: What is Granulated Blast Furnace Slag?
Granulated Blast Furnace Slag (GBFS) is a by-product of ironmaking. It is produced by rapidly cooling molten slag from a blast furnace with water or steam, creating a glassy, granular material. It is not waste in the traditional sense but a valuable Supplementary Cementitious Material (SCM) used to replace Portland cement in concrete and construction applications.
In international trade, it is primarily classified under Chapter 25 (Mineral Products) because it is used as a raw material or industrial additive, rather than a metallic residue containing high concentrations of specific recoverable metals (which would fall under Chapter 26).
β οΈ Key Distinction:
- GBFS (Chemical/Mineral Use): Classified under 2520 (Cementitious materials).
- Slag Containing Recoverable Metals (e.g., Zinc, Lead): Classified under 2620 (Residues containing metals/compounds).
Note: If the slag is specifically processed to extract Zinc or other metals, it may fall under 2620.19 or 2620.99, but standard GBFS for construction is 2520.

|---|---|---|
| β Product Specification Sheet | βοΈ | Must clearly state "Granulated Blast Furnace Slag" and its primary use (Cement vs. Zinc Recovery). |
| β MSDS (Material Safety Data Sheet) | βοΈ | Required for all industrial residues. Must show non-hazardous status if claiming 2520. |
| β Certificate of Analysis (COA) | βοΈ | To prove metal content (Zinc, Arsenic levels). Critical for distinguishing between 2520 and 2620. |
| β Bill of Lading | βοΈ | Ensure "Granulated Slag" is specified, not just "Industrial Waste." |
| β Commercial Invoice | βοΈ | Clearly describe HS Code and value. |
| β Origin Certificate | βοΈ | To determine applicability of Section 301 tariffs. |
β 2. Declaration Tips (Key Mantras)
π₯ "Use Defines Code: Cement = 2520, Metal = 2620!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| GBFS for Cement Production | 2520.10 |
Declare as "Waste" β Risk of rejection |
| GBFS for Road Fill | 2520.90 |
Declare as "Zinc Slag" β Wrong tax rate |
| Slag for Zinc Recovery | 2620.19.60.30 |
Declare as "Construction Material" β Wrong tax rate |
| General Industrial Residue | 2620.99.85.00 |
Declare as "Raw Material" β 25% Tax Trap |
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Hazardous Waste Classification | If Arsenic levels exceed thresholds, it may be classified as Hazardous Waste (RCRA). Ensure COA proves compliance with EPA limits. |
| Mixed Use (Cement + Metal) | If slag is sold for both cement and metal recovery, declare based on primary intended use at time of import. |
| Section 301 Exclusions | Check if your specific product was excluded from Section 301 tariffs. Most mineral products are not excluded. |
| De Minimis (Section 321) | Rarely applies to bulk industrial slag. Expect formal entry (Type 01 or 02). |

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
