Stone Worked Products

🪨 Stone Worked Products (Worked Monumental or Building Stone)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Stone"?

"Stone Worked Products" refer to natural stone that has undergone processing such as cutting, sawing, polishing, or carving. In international trade, these are not a single category but are divided based on shape, size, and specific use. Misclassification is the #1 cause of customs delays and high tariffs for stone products.

⚠️ Key Distinction Point:
- If the stone is cut into small cubes (<7cm side) or tiles for mosaics/flooring → It falls under Heading 6802.10.
- If it is used for monuments, headstones, or structural markers → It falls under Heading 6802.99.
- If it is processed into industrial/non-building articles (like talc tablets or carbon fiber shapes) → It falls under Heading 6815.99.

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

Based on the provided <DATA>, here are the specific HS Codes and their corresponding applications:

🔍 Important Reminder:
- "Natural Stone" vs. "Agglomerated Stone": Products under 6810 are typically agglomerated (stone dust/binders), whereas 6802 is natural stone. Misidentifying agglomerated stone as natural stone can lead to incorrect duty assessments.
- Size Matters: For 6802.10, the 7cm rule is critical. If any face exceeds 7cm, it does NOT belong in 6802.10.

💰 III. 2026 Latest Tariff Rate Details (Including Surcharges)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: 2025+ (Current Data)

🎯 1. 6802.10.00.00 —— Small Stone Cubes/Tiles (<7cm) & Granules

📌 Explanation:
- Small decorative stone cubes, mosaics, and granules are currently exempt from additional tariffs.
- This is a favorable category for low-value decorative stone products.

🎯 2. 6802.99.00.30 —— Monuments, Bases, and Markers

📌 Explanation:
- High Tax Burden: This category carries a significant total tariff of 31.5%.
- Why?: Monumental stone (headstones, statues) is considered a luxury or non-essential structural item in US trade policy, attracting both standard and punitive tariffs.

🎯 3. 6810.19.12.00 & 6810.19.14.00 —— Agglomerated Stone Tiles

📌 Explanation:
- Tariff-Free: Agglomerated stone tiles (resin-bound) are currently 0%.
- Caution: Ensure your product is indeed "agglomerated with binders other than cement." If it contains cement, it might fall under different headings not listed here, or potentially higher tariffs if not specified.

🎯 4. 6815.99.20.00 —— Talc, Steatite, Soapstone Products

📌 Explanation:
- Industrial Surcharge: Talc and soapstone products (e.g., crayons, insulators) face a flat 25% surcharge.
- Use Case: Common in cosmetics (talc) or industrial insulation (steatite).

🎯 5. 6815.99.41.10 —— High Magnesia (MgO) Resin-Bonded Articles

📌 Explanation:
- Specific Composition: Must contain >70% MgO and <30% Carbon, bonded with resin/pitch.
- Industrial Use: Often used in refractory or chemical-resistant applications. Tariff is 25%.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)

✅ 1. Required Documentation Checklist (None Missing)

✅ 2. Declaration Tips (Key Mnemonics)

🔥 "Size Check, Material Check, Use Check!"

📌 Critical:
- If you declare 6802.10.00.00 (Tiles/Cubes), ensure the largest face is <7cm. If it's 8cm, you must use 6802.99 or another subheading, which may change the tariff or require different documentation.

✅ 3. Special Cases

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- The US is the most expensive market for monumental stone (31.5%) due to tariffs.
- Small decorative stones (<7cm) and agglomerated tiles are tariff-free (0%) in the US, making them more competitive.
- Strategic Tip: If possible, design products to fit into the <7cm cube/tile category (6802.10) to avoid the 25-31.5% tariff burden on larger monumental stone.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring a 10cm x 10cm marble plaque as 6802.10.00.00 (Tiles/Cubes <7cm)
👉 Consequence: Customs will reclassify to 6802.99.00.30 → Back taxes of 31.5% + Penalties.

❌ Mistake 2: Declaring resin-bound agglomerated tile as natural stone 6802.99
👉 Consequence: Incorrect description. While tax might be similar (0% vs 31.5%), it triggers an audit for misrepresentation of material.

❌ Mistake 3: Not providing chemical composition for 6815.99.41.10 (MgO >70%)
👉 Consequence: Customs cannot verify the specific subheading → Delayed clearance or forced into a higher-tariff general category.

✅ Correct Practice:

"Marble Cube, 5cm x 5cm, Natural Stone, Unpolished, for Mosaic Use, HS 6802.10.00.00"
vs.
"Monumental Headstone, Granite, Polished, Base Included, HS 6802.99.00.30"

🎯 VII. Conclusion: Precision is Profit!

🎯 Remember the Mnemonic:

🔹 "Small Cubes <7cm? 0% Tax!"
🔹 "Monumental Stone? 31.5% Tax!"
🔹 "Agglomerated Tile? 0% Tax!"
🔹 "Talc/Steatite? 25% Tax!"

📌 Pro Tip:
If your product is agglomerated stone, always emphasize "Resin-Bound" or "Non-Cement Binder" in the declaration to secure the 0% tariff under 6810 rather than being scrutinized as natural stone.

📣 Immediate Action:

📞 Verify Dimensions: Measure the largest face. If >7cm, do not use 6802.10.
📞 Check Composition: For 6815.99.41.10, ensure lab reports are ready.
📞 Consult a Broker: For large shipments of monumental stone, consider HS Code Pre-Ruling to avoid surprise 31.5% tariffs.
