Paving stones and other mineral materials

🧱 Paving Stones & Other Mineral Materials (Natural Stone)

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

Natural stone, particularly worked monumental or building stone (excluding slate), is a critical material in construction, landscaping, and monument-making. In international trade, it is strictly divided based on geometry, processing depth, and thickness.

1. Mosaic Cubes / Small Tiles:
- Irregular or regular small pieces (cubes, chips, powder) used for mosaics or decorative flooring.
- Key Constraint: The largest face must fit within a square of less than 7 cm.

2. Worked Building Stone (Granite/Other):
- Large slabs, blocks, or tiles used for monumental or building purposes.
- Key Constraint: Must be cut to size and surface-worked (more than just sawn).
- Thickness Test: The distinction often hinges on whether the maximum thickness is greater than 7.5 cm.

⚠️ Critical Distinction Point:
- If the stone pieces are < 7 cm in largest dimension → Heading 6802.10.00.00 (Mosaic/Tile category).
- If the stone is a large block/slab for buildings, with thickness > 7.5 cm and surface-worked → Heading 6802.93.00.60 (Other granite articles).

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

🔍 Key Reminder:
- < 7 cm Rule: Any natural stone piece (even if cut) whose largest face exceeds 7 cm cannot be classified under 6802.10.00.00, even if intended for mosaics.
- Thickness > 7.5 cm: For granite building articles, if the thickness is ≤ 7.5 cm, it may fall under a different subheading (not listed in the provided data). The provided data specifically targets articles with thickness > 7.5 cm.
- Surface Work: "Simply cut or sawn" is not enough for 6802.93.00.60; it requires additional surface working (polishing, flamed, sandblasted, etc.).

💰 3. 2026 Latest Tariff Rate Details (Including Surcharges)

✅ Applicable Countries: United States (US)
✅ Origin: China (CN) (Based on the significant surtax in the data, typical of US-China trade context)
✅ Effective Time: Current 2026 Tariff Schedule

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

📌 Explanation:
- Small natural stone products like mosaic cubes are classified under 0% duty.
- No additional surtaxes are applied to this specific subheading in the provided data.
- This makes 6802.10.00.00 a highly favorable classification for importers, assuming the product strictly meets the "< 7 cm" criteria.

🎯 2. 6802.93.00.60 —— Other Granite Articles (Thickness > 7.5 cm)

📌 Explanation:
- Base Duty (3.7%): Standard Most Favored Nation (MFN) rate for other worked granite articles.
- Additional Surtax (25%): Applied under Section 301 of the Trade Act of 1974 for products originating from China.
- Total Cost Impact: Importers must pay 28.7% of the CIF value. This significantly increases the landed cost.
- Risk: Misclassification as 6802.10.00.00 to avoid the 25% surtax is a high-risk customs violation if the product exceeds 7 cm or is thick granite.

🌍 5. Global Market Comparison (2026)

📌 Conclusion:
- USA is the only major market with the 25% additional surtax on specific Chinese natural stone articles.
- Strategy: If possible, design products to fit the < 7 cm category (6802.10.00.00) to achieve 0% duty.
- Risk: Do not misrepresent large granite slabs as small tiles. Customs uses lasers and calipers.

📌 6. Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Classifying 8 cm thick granite slabs as "Mosaic Tiles"
👉 Consequence: 25% surtax evasion attempt → Seizure + Heavy Penalties

❌ Error 2: Not measuring the "Largest Face" correctly
👉 Consequence: A 6 cm x 8 cm tile has a largest face of 8 cm (> 7 cm) → Cannot use 0% rate

❌ Error 3: Assuming all "Natural Stone" is the same
👉 Consequence: Slate is excluded. Marble vs. Granite may have different subheadings. Granite is specifically cited in 6802.93.00.60.

❌ Error 4: Ignoring "Surface Worked" requirement
👉 Consequence: Simply sawn granite may not fit 6802.93.00.60 → Incorrect Classification

✅ Correct Declaration Example:

"Natural Granite Mosaic Cubes, each 5cm x 5cm, polished surface, for flooring decoration" → 6802.10.00.00 (0%)
"Worked Granite Monumental Block, 100cm x 50cm x 10cm, flamed surface, for building cladding" → 6802.93.00.60 (28.7%)

🎯 7. Conclusion: Precision Pays Off

🎯 Key Takeaway:

🔹 Small & Flat (< 7 cm) = 0% Duty (6802.10.00.00)
🔹 Large & Thick (> 7.5 cm) = 28.7% Duty (6802.93.00.60)
🔹 Misclassification = High Risk

🔹 "Check the 7 cm rule, measure the 7.5 cm thickness, and save 28.7%!"

📌 Pro Tip:
If you are importing large granite, consider supply chain diversification (e.g., sourcing from non-China origins) to mitigate the 25% surtax. For small mosaics, focus on the < 7 cm design to maximize tariff benefits.
