🏛️ Stone Paving & Building Stone (Granite & Calcareous)

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

"Worked monumental or building stone" refers to natural stone that has been cut, sawn, or shaped for construction, monumental, or decorative purposes. It excludes slate (heading 6801) and excludes mosaics or colored granules.

In international trade, this category is primarily divided into two critical sub-categories based on the mineral composition and surface treatment:

1. Granite (Hard, Igneous Stone)
Characteristics: High durability, heat resistant, dense.
Key Identifier: Typically gray, pink, or speckled; used for high-traffic flooring, facades, and monuments.
HS Code Focus: 6802.23.00.00*

2. Calcareous Stone (Limestone, Travertine, Alabaster - Excluding Marble)
Characteristics: Softer than granite, susceptible to acid etching, often lighter in color.
Key Identifier: If it reacts with vinegar (acid test) and is not marble/travertine/alabaster, it falls here.
HS Code Focus: 6802.29.10.00*

⚠️ Key Distinction Point:
- If the stone is Granite → Use 6802.23.00.00
- If the stone is Calcareous (Limestone/etc.) → Use 6802.29.10.00
- Note: Marble is a different heading and not included in this specific data scope.

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

🔍 Important Reminder:
- 6802.23.00.00 is for Granite. It has 0% Basic Tariff.

- Both categories are subject to 25% Additional Tariff if originating from China (under Section 301 trade remedies).
- Do not confuse "Calcareous Stone" with "Marble." Marble has its own specific sub-headings not listed in the provided data.

🎯 1. 6802.23.00.00 —— Granite (Simply Cut/Sawn, Flat Surface)

- Additional Rate: 25% is applied due to trade tensions (Section 301).
- Net Cost Impact: You pay 25% extra on top of the CIF value. No hidden surcharges in the provided data, but verify local port fees.

🎯 2. 6802.29.10.00 —— Calcareous Stone, Other Than Marble, Travertine or Alabaster

📌 Explanation:

🌍 V. Global Market Clearance Comparison (2026 Context)

📌 Conclusion:
- USA is the most expensive market for Chinese stone due to the 25% Section 301 tariff on top of basic rates.
- Granite is cheaper to import than Calcareous Stone in the US (25% vs 29.9%).
- Always verify if your specific product type has been excluded from Section 301 tariffs.

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

❌ Error 1: Classifying Marble under 6802.29.10.00
👉 Consequence: High risk of audit. Marble has its own sub-headings (e.g., 6802.93/94). Misclassification leads to back taxes + penalties.

❌ Error 2: Not distinguishing Granite from Calcareous Stone
👉 Consequence:
- If you classify Calc as Granite → You underpay 4.9%. Customs will demand back payment + interest.
- If you classify Granite as Calc → You overpay. No refund easy.

❌ Error 3: Vague Description ("Natural Stone Blocks")
👉 Consequence: Customs may assign a higher default rate or detain the shipment for inspection.

❌ Error 4: Ignoring Section 301 Exclusions
👉 Consequence: Some granite products have been removed from the 25% tariff list. If you still pay 25% when exempt, you waste money. Check USITC Exclusion Lists!

✅ Correct Practice:

"Granite, Worked, Simply Sawn, Flat Surface, Polished, 3cm Thickness, Origin: China"
+ Attach Lab Report Confirming Igneous/Granite Composition.

🎯 VII. Conclusion: Professional Declaration Saves Money!

🎯 Remember the Mnemonic:

🔹 "Granite: 0% Base + 25% Add = 25%"
🔹 "Calc: 4.9% Base + 25% Add = 29.9%"
🔹 "Marble: Check Elsewhere!"
🔹 "Slate: Heading 6801!"

📌 Pro Tip:
- Get a Pre-Ruling: For large shipments, apply for an Advance Ruling from US Customs (CBP) to lock in the HS code and tariff rate.
- Verify Origin: Ensure your supplier provides accurate Country of Origin documentation. If the stone is from India or Brazil, the 25% tariff does not apply! This can save you 25-30% instantly.

📣 Immediate Action:

📞 Contact Your Broker: Provide product photos + mineral composition report.
🚀 Check Exclusions: Verify if your granite product is on the USITC Section 301 Exclusion List.
💼 Cost Optimization: If possible, source from non-Chinese countries to avoid the 25% surcharge.
