ποΈ Natural Stone Slate Articles: The Ultimate Classification & Tariff Guide (2026)
π HS Code Reference & Customs Clearance Strategy | 2026 Latest Tariff Analysis | Professional Import/Export Compliance
π I. Product Definition & Classification: Do You Really Understand "Slate Articles"?
Natural Stone Slate Articles refer to products made from natural sedimentary rock (specifically slate or related calcareous stones), cut into sheets, tiles, or specific shapes for construction, decoration, or industrial use.
In international trade, "slate" is not just one HS Code. It is split based on material composition and processing level. Misclassification here leads to severe tariff shocks due to Section 301 and Section 122 duties targeting Chinese stone products.
β οΈ Key Distinction Point:
- Is the stone calcareous (like marble/limestone) vs. non-calcareous (like granite)?
- Is it roughly worked (blocks/slabs) or finely worked (tiles/countertops)?
- Slate specifically often falls under Chapter 25 if it's unworked or simply cut, but if it's "articles" (shaped items), it might shift to Chapter 68.
- CRITICAL: For US Imports from China, Chapter 25 and Chapter 68 items are subject to heavy Additional Duties (25%) + Section 122 Duties (10%).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Alignment)
Based on the provided data, here are the 5 valid HS Codes for Natural Stone Slate Articles, sorted by tax efficiency.
| HS Code | Product Description | Summary/Logic | Total Tax Rate | Key Components |
|---|---|---|---|---|
| 2515.20.00.00 | Natural Stone (incl. Slate) & Articles | Best Value. Slate is explicitly mentioned. Covers slate tiles/flagstones. | 38.0% | Base: 3.0%, Addl: 25%, Sec 122: 10% |
| 6802.10.00.00 | Natural Stone Articles (Marble/Travertine) | High Tax. Covers "materials match" but assumes marble/travertine family. | 39.8% | Base: 4.8%, Addl: 25%, Sec 122: 10% |
| 6803.00.10.00 | Worked Slate & Slate Articles | Medium-High Tax. Specifically mentions "Slate" but in Chapter 68 (Worked Stone). | 38.3% | Base: 3.3%, Addl: 25%, Sec 122: 10% |
| 2515.11.00.00 | Marble & Travertine (incl. Slabs) | High Tax. If your "slate" is calcareous (calcium-based), it may be misclassified as Marble. | 35.0% | Base: 0.0%, Addl: 25%, Sec 122: 10% |
| 6802.99.00.90 | Other Worked Stone Articles | Highest Tax. Catch-all for worked stone not specified elsewhere. | 41.5% | Base: 6.5%, Addl: 25%, Sec 122: 10% |
π Critical Analysis:
- Why 2515.20.00.00 is often the BEST choice: It explicitly includes Slate and has the lowest base duty (3.0%) among the slate-specific options.
- Why 6803.00.10.00 is risky: It is for "Worked Slate," but the base duty is higher (3.3%) than 2515.20.
- Why 2515.11.00.00 is dangerous: If your stone is NOT marble/travertine, classifying it here is misclassification, leading to penalties. However, if it is calcareous, the 0% base makes it the lowest total tax (35%).
- Why 6802.99.00.90 is a last resort: Highest base duty (6.5%). Use only if no other code fits.

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Required? | Purpose |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must state: "Natural Slate," "Non-Calcareous," dimensions, thickness. |
| β Photographs (Raw & Finished) | βοΈ | Show layering/foliation typical of slate. Prove it is NOT marble. |
| β Commercial Invoice | βοΈ | Clearly describe as "Slate Tiles" or "Slate Artifacts," NOT "Stone Slabs" or "Marble." |
| β Packing List | βοΈ | Weight and dimensions for duty calculation. |
| β Origin Certificate (Form A) | β (for China) | DO NOT claim preferential origin. China is subject to 25% + 10% duties. |
| β Material Test Report | βοΈ (Recommended) | Chemical test proving low calcium carbonate content to defend against 2515.11 misclassification. |
β 2. Classification Strategy (Key Rules)
π₯ "Slate is Slate, Not Marble. Chapter 25 is Cheaper than 68."
| Scenario | Recommended HS Code | Reason |
|---|---|---|
| True Slate, Cut into Tiles/Slabs | 2515.20.00.00 |
Explicitly covers slate. Lowest base (3.0%). |
| True Slate, Fine Artifacts (e.g., Chessboards) | 6803.00.10.00 |
Chapter 68 for worked articles. Base 3.3%. |
| Calcareous Stone (Marble/Travertine) | 2515.11.00.00 |
Only if tested as calcareous. Lowest total (35%). |
| Granite/Quartz (Non-Calcareous, Non-Slate) | 6802.99.00.90 |
If not slate or marble, use catch-all. |
| Unidentified "Stone" | β STOP | Do not guess. Provide test reports. |
β 3. Special Cases & Defenses
| Situation | Advice |
|---|---|
| Customs Questions "Is this Marble?" | Provide a mineralogical report showing foliated texture and low calcite content. |
| "Slate" vs. "Slate Tiles" | Both can use 2515.20.00.00. The key is natural state + cutting. |
| Section 122 Exemption? | No known exemptions for Chinese stone. Plan for 10% addl duty. |
| De Minimis (Section 321) | NOT ELIGIBLE. All stone articles from China >$800 are fully taxed. |
π V. Global Market Comparison (2026)
| Market | Recommended HS | Base Duty | Addl Duties | Total (China) | Notes |
|---|---|---|---|---|---|
| πΊπΈ USA | 2515.20.00.00 |
3.0% | +35% (25%+10%) | 38.0% | Most Complex. Strict scrutiny on "Slate." |
| πͺπΊ EU | 2515.20.00 |
~0-3% | 0% (No Sec 301) | ~3% | Best Market. No retaliatory tariffs. |
| π¨π³ China | 2515.20.00 |
3.0% | 0% | 3.0% | Low cost. |
| π¬π§ UK | 2515.20.00 |
~0-3% | 0% | ~3% | No US-style Section 122. |
π Strategy:
- If targeting USA, ensure accurate classification to avoid penalties.
- If targeting EU/UK, consider shifting supply chain to avoid US tariffs if volume is high.
π VI. Common Errors & Pitfalls (Blood Lessons)
β Error 1: Calling "Slate" "Marble Slabs" to get 0% base duty
π Consequence: Customs audits test reports. If itβs slate, penalty + back taxes.
β Error 2: Using 6802.99.00.90 for simple slate tiles
π Consequence: Paying 41.5% instead of 38.0%. Loss of $3,500 per $100k shipment.
β Error 3: Assuming "Slate" is exempt from Section 122
π Consequence: 10% surprise duty upon inspection. Budget for it!
β Correct Declaration Example:
"Natural Slate Tiles, Unfired, Cut to Size, Non-Calcareous, for Wall Cladding, HS 2515.20.00.00"
π― VII. Conclusion: Precision Saves Money
π― Key Takeaways:
1. True Slate β Use 2515.20.00.00 (38.0% Total).
2. Worked Slate Articles β Use 6803.00.10.00 (38.3% Total).
3. Calcareous Stone β Use 2515.11.00.00 (35.0% Total) ONLY if tested.
4. Never Guess. Provide mineralogical proof.
πΉ "HS Code is King, Test Report is Queen."
πΉ "Slate is not Marble. Don't mix them up."

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
