๐ I. Product Definition & Classification: What Exactly Is "Nepheline Syenite"?
Nepheline Syenite is an alkaline intrusive igneous rock, chemically similar to granite but with less silica and higher feldspathoids (nepheline). It is a critical raw material widely used in the glass and ceramics industries due to its low melting point and high alumina content.
In international trade, it is generally classified based on its form and intended use:
1. Raw Ore / Rough Stone:
- Quarried blocks or crushed stone not yet processed for specific industrial use.
- Often used as aggregate or in construction if quality permits.
2. Processed Mineral for Ceramics/Glass:
- Crushed, milled, and purified nepheline syenite powder.
- Used as a flux in porcelain, sanitary ware, and glass manufacturing.
โ ๏ธ Key Distinction:
- If sold as raw quarried stone or crushed aggregate without specific chemical processing โ Typically falls under Chapter 25 (Salt; Sulfurs; Earths and Stone).
- If sold as a specifically prepared mineral mixture for ceramics/glass (often with additives) โ May fall under Chapter 38 (Miscellaneous Chemical Products) or Chapter 68 (Mineral Products).
- Most Common Classification: 2517.49 (Crushed/Screened Stone for Construction/Industry) or 2517.10 (Pebbles). However, for high-purity industrial use, customs may scrutinize if it qualifies as a chemical product or mineral preparation.
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Alignment)
| HS Code | Product Description | Application Scenario | Key Characteristics |
|---|---|---|---|
2517.49.00.00 |
Other crushed or powdered stone (nepheline syenite, feldspar, quartz, etc.) for industrial use | Ceramics, glass, filler material | Crushed, milled, possibly washed |
2517.10.00.00 |
Gravel, pebbles, cobblestones | Construction aggregate, landscaping | Raw, uncrushed or minimally processed |
2517.20.00.00 |
Slag, dross, ashes (not applicable to nepheline syenite) | โ | โ |
2517.30.00.00 |
Natural stone blocks, slabs, tiles | Building materials (countertops, cladding) | Cut to size, polished or rough |
3824.99.92.00 |
Prepared binders for foundry molds; chemical products (if highly processed) | Specialized chemical applications | If mixed with binders or chemically treated |
7019.90.00.00 |
Glass fibers and articles thereof (not applicable) | โ | โ |
๐ Critical Note:
- Primary Classification: Most nepheline syenite imported for ceramics and glass is classified under2517.49.00.00(Other crushed/powdered stone).
- Avoid Misclassification: Do not classify as2505.90(Sand) unless it is purely sand-sized. Nepheline syenite is a rock, not sand.
- High-Purity Powder: If the material is ultra-fine and chemically modified, some customs authorities may argue for3824.99.92.00, but this is rare for standard nepheline syenite. Stick to2517.49.00.00unless explicitly advised otherwise.

โ Applicable Country: United States (US)
โ Origin: China (CN)
โ Effective Date: From November 10, 2025 (including subsequent imports)
๐ฏ 1. 2517.49.00.00 โโ Crushed/Powdered Nepheline Syenite (Industrial Use)
| Item | Content |
|---|---|
| Base Rate | 5% (ad valorem) |
| USITC Surcharge (Section 301) | +7.5% (for products under 2517.49.00.00 from China) |
| IEEPA Surcharge | +10% (against Chinese/Hong Kong products, effective Nov 10, 2025) |

| Legal Basis Path | IEEPA:9903.01.25 โ USITC:2517.49.00.00 โ FOOTNOTE:301.03.05 |
๐ Explanation:
- 5% is the standard MFN (Most Favored Nation) rate for crushed stone for industrial use.
- 7.5% is the Section 301 tariff applied to specific mining/crushed stone products from China.
- 10% is the IEEPA surcharge for Chinese-origin goods.
- Total: 22.5%. This is a moderate-to-high tariff compared to raw stone, so accurate declaration is crucial.
๐ฏ 2. 2517.10.00.00 โโ Nepheline Syenite Gravel/Pebbles (Construction Grade)
| Item | Content |
|---|---|
| Base Rate | 5% |

| De Minimis Exemption | โ Not Available |
๐ Note:
- If the nepheline syenite is sold as construction aggregate (gravel/pebbles), it still faces the same high tariffs.
- Do not misdeclare as2517.10.00.00if it is milled powder for ceramics, as this may trigger audits for undervaluation or incorrect classification.

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) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ 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 โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
