🪨 Natural Stone Slabs (Marble, Travertine, Quartzite)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Know the Difference Between "Marble" and "Other Stones"?

Natural stone slabs are fundamental materials in construction, interior design, and monumental works. In international trade, the distinction between Marble/Travertine/Alabaster and Other Stones (e.g., Quartzite) is critical, as it dictates a massive difference in tariff exposure.

1. Marble, Travertine, and Alabaster Slabs:
Polished or sawn slabs made from these specific carbonate rocks. These are generally considered premium decorative materials.

2. Quartzite and Other Natural Stone Slabs:
Quartzite is a hard metamorphic rock composed primarily of quartz. It is often used for countertops and heavy-duty flooring due to its durability.

⚠️ Key Distinction Point:
- If the stone is Marble, Travertine, or Alabaster → It falls under 6802.91.
- If the stone is Quartzite, Granite, Limestone (other than travertine), etc. → It falls under 6802.99.
- Do not mix them! Misclassifying Quartzite as Marble could lead to severe penalties for underpayment of tariffs.

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

🔍 Critical Reminder:
- Marble/Travertine/Alabaster enjoy a 0% basic tariff.
- Quartzite (and other non-marble stones) are subject to a 31.5% total tariff.
- This 31.5% includes both the Basic Tariff (6.5%) and the Additional Tariff (25.0%).

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

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: As per current USITC and USTR regulations

🎯 1. 6802.91.05.00 —— Marble, Travertine, and Alabaster Slabs

📌 Explanation:
- This category benefits from a zero-duty status for basic imports from China.
- Crucial Note: While the basic rate is 0%, ensure the goods are genuinely Marble, Travertine, or Alabaster. If Customs determines the stone is actually Quartzite or Granite, they will reclassify it to 6802.99, triggering the 31.5% tariff.
- Risk: High risk of misclassification. Geological testing may be required if the stone's origin is ambiguous.

🎯 2. 6802.99.00.50 —— Quartzite and Other Stone Slabs

📌 Explanation:
- Quartzite is classified under "Other Stone."
- The 6.5% is the standard Most Favored Nation (MFN) rate.
- The 25.0% is the additional tariff imposed under Section 301 of the Trade Act of 1974 on certain Chinese goods.
- Total Impact: For every $10,000 CIF value, you must pay $3,150 in duties. This significantly impacts the landed cost of quartzite countertops and flooring.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)

✅ 1. Preparation Checklist (Essential Documents)

✅ 2. Declaration Tips (Key Mantra)

🔥 "Identify the Rock Type! Marble is Free, Quartzite is Heavy!"

📌 Note:
- Travertine is a form of limestone but is specifically grouped with Marble for tariff purposes under 6802.91.
- Granite is not included in 6802.91; it falls under 6802.99 (Other Stone), making it subject to the 31.5% tariff.

✅ 3. Special Handling Cases

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- The US is the only major market with a massive tariff gap (0% vs. 31.5%) based on stone type.
- EU/UK are more tariff-friendly, but compliance with construction product regulations (CE/UKCA) is strict.

📌 VI. Common Errors & Pitfall Guide (Lessons from Blood and Tears)

❌ Error 1: Calling Quartzite "Marble" to save 31.5%
👉 Consequence: Customs lab tests prove it's quartz-rich metamorphic rock. You face 31.5% back duty + 25% penalty + legal fees.

❌ Error 2: Confusing "Natural Stone Slabs" with "Engineered Quartz"
👉 Consequence: Engineered quartz (resin + crushed stone) is often classified under 6802.93 or 3926, not 6802.99. Misclassification leads to audit flags.

❌ Error 3: Ignoring "Travertine" Distinction
👉 Consequence: Travertine is legally grouped with Marble (0% tariff). If you declare it as "Limestone" (Other Stone), you might pay 6.5% unnecessarily, though less severe than the 31.5% risk.

✅ Correct Practice:

"Natural Marble Slabs, Polished, Carrara Type, Honed Edges, Origin: China, HS: 6802.91.05.00"
OR
"Natural Quartzite Slabs, Polished, Green Galaxy, Origin: China, HS: 6802.99.00.50"

🎯 VII. Conclusion: Precise Classification Saves 31.5% of Your Cost!

🎯 Remember the Mantra:

🔹 "Marble/Travertine/Alabaster = 0% Tax!"
🔹 "Quartzite/Granite/Other = 31.5% Tax!"
🔹 "Don't Guess the Stone! Lab Test if Unsure!"

📌 Pro Tip:
If you are importing Quartzite, consider:
1. Supply Chain Shift: Sourcing from Vietnam, India, or Brazil where Section 301 tariffs may not apply (check specific origin rules).
2. Pre-Ruling: Apply for a Customs Ruling from CBP before shipment to confirm the HS Code if the stone type is borderline.

📣 Immediate Action:

📞 Consult a licensed customs broker.
📄 Provide geological data sheets for your stone.
🚀 Avoid the 31.5% surprise by getting the HS Code right the first time!
