𧱠Concrete Brick (Cement/Concrete/Artificial Stone Articles)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Know "Concrete Bricks"?
Concrete bricks are fundamental construction materials made from cement, aggregate, and water. In international trade, they fall under Chapter 68 (Articles of stone or of other mineral substances). However, not all concrete blocks are created equal. They are strictly divided based on chemical composition and binding agents.
Standard Concrete/Building Blocks: The generic "grey bricks" used for general construction.
Magnesia-Based Bricks: Specialized bricks containing significant amounts of Magnesia (MgO), often bonded with resin or pitch for specific industrial or fire-resistant applications.
β οΈ Key Distinction Point:
- If the brick is made of standard cement/concrete β 6810.11.00.70
- If the brick contains >70% Magnesia (MgO) and is bonded by resin/pitch β 6810.11.00.10
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Key Differentiator |
|---|---|---|---|
6810.11.00.70 |
Building blocks and bricks (Other) | Standard cement, concrete, or artificial stone bricks; general construction use | β Standard Cement/Concrete |
6810.11.00.10 |
Bricks with >70% MgO, chemically bonded by resin or pitch | Specialized industrial bricks, fireproof materials, chemical-resistant blocks | β High Magnesia Content + Resin/Pitch Bond |
π Critical Reminder:
- The code6810.11.00.70is the "catch-all" for typical concrete bricks.
- The code6810.11.00.10is highly specific. It requires two conditions:
1. Weight percentage of Magnesia (MgO) must be >70%.
2. Carbon content must be trace to <30%.
3. Binding agent must be resin or pitch (not just cement).
- If you classify a standard concrete brick under6810.11.00.10, customs will likely reject it due to lack of Magnesia/resin evidence.
π° III. 2026 Latest Tariff Rate Details (Including Surcharges & Policy Additions)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Time: 2025-11-10 onwards (and subsequent imports)
π― 1. 6810.11.00.70 ββ Standard Building Blocks and Bricks (Other)
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (ad valorem) |
| Section 301 Surcharge | 0.0% |
| Total Tariff | 0.0% |
| Tax Calculation | CIF Value Γ 0% = $0 |
| De Minimis Exemption | β Yes (Generally eligible if value <$800, subject to specific trade policies) |
| Legal Basis Path | USITC:6810.11.00.70 |
π Explanation:
- Standard concrete bricks are considered basic construction materials.
- Unlike high-tech electronics or steel, cement-based products often face lower or zero additional tariffs from the US, as they are not prioritized targets for Section 301 or IEEPA restrictions in the same way.
- Total Tax: 0%. This makes concrete bricks highly competitive in the US market compared to steel or aluminum products.
π― 2. 6810.11.00.10 ββ Magnesia-Based Bricks (>70% MgO, Resin-Bonded)

| Section 301 Surcharge | 0.0% |
| Total Tariff | 0.0% |
| Tax Calculation | CIF Value Γ 0% = $0 |
| De Minimis Exemption | β Yes (Same as above, subject to general de minimis rules) |
| Legal Basis Path | USITC:6810.11.00.10 |
π Explanation:
- Even these specialized industrial bricks enjoy 0% total duty.
- Total Tax: 0%.
- Warning: While the tariff is 0%, the customs scrutiny on classification is high. You must provide chemical composition reports and technical specifications proving the >70% MgO content and resin bonding. Misclassification can lead to delays.
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Preparation Checklist (Missing Items Will Cause Delays)
| Document | Mandatory? | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must detail dimensions, weight, compressive strength, and chemical composition. |
| β Technical Data Sheet (TDS) | βοΈ | Crucial for 6810.11.00.10. Must explicitly state MgO content (%) and binder type (Resin/Pitch). |
| β Product Photos | βοΈ | Show the brick surface, packaging, and any labels. |
| β Commercial Invoice | βοΈ | Clearly describe as "Concrete Building Block" or "Magnesia Brick." Avoid vague terms like "Construction Material." |
| β Packing List | βοΈ | Detail net/gross weight per carton. |
β 2. Declaration Tips (Key Mnemonics)
π₯ "Be Specific, Be Chemical, Or Get Rejected!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Standard Grey Brick | 6810.11.00.70 - "Concrete Building Blocks" |
Calling it "Ceramic Brick" or "Clay Brick" β Wrong Chapter! |
| Fireproof Industrial Brick | 6810.11.00.10 - "Magnesia Brick, >70% MgO, Resin-Bonded" |
Calling it "Concrete Block" β Customs may reclassify or ask for proof. |
| Mixed Shipment | Declare separately by HS Code | Mixing standard and MgO bricks in one line item β Customs will split and tax/penalize based on the worst case. |
β 3. Special Circumstances Handling
| Scenario | Handling Advice |
|---|---|
| Bricks with Metal Reinforcement | If heavily reinforced, check Chapter 73 (Steel). But typical "concrete blocks" remain in Ch. 68. |
| Sample Shipments (De Minimis) | For small samples under $800, you can use the De Minimis route, but still declare the correct HS Code. Customs still reviews 6810 codes for accuracy. |
| High-Value Specialized Bricks | Even with 0% tariff, ensure the value declaration matches the invoice. Under-invoicing on specialized bricks can trigger audits. |
π V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification/Notes |
|---|---|---|---|
| πΊπΈ USA | 6810.11.00.70 / .10 |
0% | No major non-tariff barriers for standard bricks. |
| π¨π³ China (Import) | 6810.11 |
5-10% | Depends on origin; check Free Trade Agreements (e.g., RCEP). |
| πͺπΊ EU | 6810.11 |
0-6% | Varies by member state. CE marking not required for bricks, but environmental declarations may be needed. |
| π¬π§ UK | 6810.11 |
0-6% | Post-Brexit, check UK Global Tariff. Generally low. |
| π¦πΊ Australia | 6810.11 |
5% | Standard import duty. May require biosecurity checks if packaging contains organic matter (rare for concrete). |
π Conclusion:
- USA offers 0% duty for both standard and specialized concrete/magnesia bricks, making them very attractive.
- Classification accuracy is the primary risk, not cost.
- China/EU/Australia have slightly higher tariffs but are still manageable.
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Classifying all concrete products under one generic code without distinguishing Magnesia content.
π Consequence: If you have specialized MgO bricks but declare them as 6810.11.00.70, customs may accept it, but you miss out on potential specific regulatory exemptions or mislead buyers. Conversely, if you declare standard bricks as 6810.11.00.10, you risk rejection due to lack of chemical proof.
β Error 2: Using vague descriptions like "Building Materials" or "Cement Blocks" on the commercial invoice.
π Consequence: Customs officials will request additional documentation, causing port delays and demurrage fees.
β Error 3: Ignoring the "Resin/Pitch" requirement for .10.
π Consequence: Many "refractory bricks" are cement-bonded, not resin-bonded. If you claim .10 for a cement-bonded brick, it is a false declaration.
β Correct Practice:
"Concrete Building Block, 20x10x5cm, Standard Grey, for General Construction, HS Code 6810.11.00.70"
OR
"Magnesia Refractory Brick, >70% MgO, Resin-Bonded, Fireproof, HS Code 6810.11.00.10"
π― VII. Conclusion: Precision in Classification Saves Time
π― Remember the Mnemonic:
πΉ "Standard Concrete? Use .70. Special MgO? Use .10."
πΉ "0% Tax is Sweet, But Proof is Key."
πΉ "Don't guess the chemical content, let the datasheet speak."
π Pro Tip:
If you are exporting specialized MgO bricks, include a Certificate of Analysis (CoA) from a third-party lab stating the MgO percentage. This speeds up customs clearance significantly, as officers can quickly verify the .10 classification.
π£ Immediate Action:
π Verify your product's chemical composition.
π If standard β Use6810.11.00.70.
π¬ If specialized (>70% MgO, Resin-bonded) β Use6810.11.00.10+ CoA.
π Smooth clearance, zero duty, happy margins!
β¨ Professional customs clearance starts with precise classification!
πΌ Every brick counts, but the right HS code counts more!

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
