📌 I. Product Definition & Classification: What is "Roughly Processed Stone"?

Roughly processed stone refers to natural stone materials that have undergone initial shaping but have not yet reached their final finished state. In international trade, these materials are primarily categorized by material type (e.g., marble, granite, sandstone) and processing level (roughly squared, roughly trimmed, or simply cut).

Key Distinction Points: - Material Type: Marble, Travertine, Onyx, etc. vs. Granite, Basalt, etc. vs. Sandstone. - Processing Level: "Roughly squared" (simple geometric shape) vs. "Roughly trimmed" (cut into slabs/blocks but unpolished). - Final Use: Not yet for construction finishing (like tiles or countertops), but rather for further加工 or structural use.

⚠️ Critical Classification Rule:
- If the stone is Marble/Travertine/Onyx, it generally falls under 2515.
- If the stone is Granite/Slate/Sandstone, it generally falls under 2516 or 6802 (if processed into specific articles).
- Rough processing implies minimal shaping (e.g., sawn blocks, roughly squared pillars) without polishing, grinding, or intricate carving.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

Based on the provided data, here is the detailed breakdown for roughly processed stone materials:

🔍 Key Reminder:
- 2515.11.00.00 is specific to Marble/Travertine/Onyx. Do not confuse with granite (which is 2516).
- 2516.11.00.00 is for Granite/Porphyry/Basalt. These are harder stones than marble.
- 2516.20.10.00 is specifically for Sandstone.
- 6802.23.00.00 covers worked stone (like simple sawn blocks) that does not fall into the specific "roughly squared" categories of Chapter 25, or is considered a "worked article" rather than a raw material.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Taxes & Policy Surcharges)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: From November 10, 2025 (including subsequent imports)

🎯 1. 2515.11.00.00 – Marble/Travertine/Onyx, Roughly Squared

📌 Explanation:
- Although the base tariff for marble is 0%, the Section 301 additional tariff of 25% applies to Chinese-origin stone products.
- The Section 122 tariff of 10% is also applied, bringing the total to 35%.
- This is a high-cost category; proper classification is critical to avoid overpayment.

🎯 2. 2515.20.00.00 – Other Limestone/Calcareous Stone, Roughly Squared

📌 Note:
- This category applies to limestone, chalk, and oolite (non-marble calcareous stones).
- The base tariff is 3%, which is higher than marble (0%).
- Total 38% makes this even more expensive than marble imports.

🎯 3. 2516.11.00.00 – Granite, Porphyry, Basalt, Roughly Squared

📌 Explanation:
- Granite is a hard stone and is classified under Chapter 2516.
- Like marble, it has a 0% base tariff but is subject to the same 35% total tax due to Section 301 and 122 tariffs.

🎯 4. 2516.20.10.00 – Sandstone, Roughly Squared

📌 Note:
- Sandstone is also classified under Chapter 2516 but in a different subheading than granite.
- The tariff rate is identical to granite: 35% total.

🎯 5. 6802.23.00.00 – Worked Stone, Simply Cut/Sawn

📌 Explanation:
- This HS code is for worked stone articles that are simply cut or sawn but do not fit the specific "roughly squared" definitions of Chapters 2515/2516.
- It has a higher base tariff (3.7%) than most marble/granite codes.
- Total 38.7% is the highest tariff rate among the listed codes. Use this only if the product does not fit other categories.

✅ 1. Required Documentation Checklist (No Exceptions)

✅ 2. Declaration Tips (Key Mantras)

🔥 "Material First, Processing Second, Name Accurate, Tax Avoided!"

⚠️ Warning:
- Do not declare polished or finished stone as "roughly processed."
- Do not mix different stone types in one declaration line without clear separation.
- Do not use vague terms like "Stone Blocks" without specifying the material.

✅ 3. Special Case Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- The US market imposes the highest effective tariff (35-38.7%) due to Section 301 and 122 measures.
- Marble and Granite have slightly lower total tariffs (35%) compared to Limestone and Worked Stone (38-38.7%).
- Non-US markets (EU, UK, AU) are significantly cheaper for stone imports.

📌 VI. Common Errors & Pitfall Guide (Lessons Learned)

❌ Error 1: Misclassifying Marble as Granite
👉 Consequence: No direct tax difference (both 35%), but may trigger customs audit for material misrepresentation.

❌ Error 2: Declaring Polished Stone as Roughly Processed
👉 Consequence: Underpayment of duties; potential fines and back taxes. Polished stone often falls under 6802 with different rates.

❌ Error 3: Vague Description: "Stone Blocks"
👉 Consequence: Customs may assign a default higher tariff code or demand additional documentation, causing delays.

❌ Error 4: Ignoring Section 122 Tariff
👉 Consequence: Underpayment by 10%; significant financial loss and penalties.

✅ Correct Practice:

"Roughly Squared Marble Blocks, Unpolished, for Construction Use, Model XYZ, Origin China"

🎯 VII. Conclusion: Professional Declaration, Cost Optimization, Risk Mitigation!

🎯 Remember the Mantra:

🔹 "Material Dictates Code, Processing Dictates Rate. Marble & Granite 35%, Limestone 38%, Worked 38.7%!"
🔹 "HS Code is Life, Tariff Difference is Wealth, Declaration Precision Saves Money!"

📌 Tips:
- If your stone is originating from Vietnam, Mexico, Thailand, or Malaysia, you may qualify for IEEPA exemptions, reducing the tariff to 0%~5%.
- It is highly recommended to apply for an Advance Ruling before shipment to ensure correct HS Code classification and avoid post-clearance disputes.
