Frequently Asked Questions
How does the specific concrete composition affect the classification under HTS 681011?
Classification under HTS 681011 is specifically for blocks and bricks made from hydraulic cements, concrete, or artificial stone. Products using non-hydraulic binders like lime or containing a predominant amount (by weight or value) of materials like wood or plastics would not be classified here and would instead fall under other HTS chapters. The key is that the material must be a coherent mass formed from cementitious or stone-like substances.
Are shipments of concrete blocks and bricks under HTS 681011 subject to high rates of customs inspection?
Yes, shipments of these goods are frequently inspected due to the risk of misclassification, often being mistaken for prefabricated building components in other chapters. Inspectors will verify the product's dimensions, composition, and lack of internal reinforcement to confirm it is a simple block or brick. Proper documentation, including detailed product descriptions and photographs, is critical to avoid delays.
What additional costs beyond the declared value should I anticipate when importing concrete blocks and bricks under HTS 681011?
You should budget for the Merchandise Processing Fee (MPF), which is 0.3464% of the entered value (minimum $29.22, maximum $648.65 per shipment). For significant shipments, you may also face port handling and warehouse demurrage fees if cargo is not moved promptly, as concrete building materials are heavy and bulky.
Material Variants & Classification
Heading 6810.11 specifically covers building blocks and bricks of cement, concrete, or artificial stone. The material is decisive: products of natural stone (e.g., granite, limestone) are classified elsewhere, typically under HTS 6801 or 6802. Similarly, lightweight blocks made from aerated concrete fall under 6810.12, while bricks of siliceous fossil meals (like diatomaceous earth) are classified in 6901. For fiber-cement products, which contain reinforcing materials like cellulose, refer to heading 6811. Always verify the primary binder and any reinforcing materials to ensure correct 8-digit classification.
Similar and Often Confused HTS Codes
Concrete blocks and bricks under 6810.11 are most commonly confused with other masonry units. A key alternative is HTS 6810.19 for "Other" articles of cement, concrete, or artificial stone, which may include non-building items like garden ornaments or statues. Builders often misclassify lightweight aerated concrete blocks (like Hebel or Ytong) here; they correctly belong to 6810.99 as "Other articles...not of cement...". Furthermore, refractory (fire-resisting) bricks of siliceous fossil meals are distinctly classified under 6902.10, not this heading.
