Description
Prefabricated structural components of cement or concrete
Precast concrete elements are prefabricated structural components of cement or concrete, and they are imported duty-free into the United States under this HTS code.
Frequently Asked Questions
For shipping precast concrete elements (HTS 681091) to the European Union, are there specific CE marking requirements for structural components?
Yes, precast concrete structural elements imported into the EU must bear the CE marking in accordance with the Construction Products Regulation (EU) No 305/2011. This requires the manufacturer to provide a Declaration of Performance and ensure the product is assessed and certified by a notified body for relevant harmonized standards, such as EN 13369 for precast concrete products.
How does the specific composition of cement or concrete affect the duty rate and classification under HTS 681091?
The precise mixture of aggregates, binders, and reinforcing materials determines whether an element is considered 'prefabricated structural components' under this heading. For example, elements containing lightweight aggregates like pumice or expanded clay may have different physical properties that could potentially affect classification, but they generally remain under 681091 if designed for load-bearing use. Reinforced elements with embedded steel are specifically included, distinguishing them from purely masonry or non-structural concrete articles.
Similar Codes & Distinguishing Features
Products under 681091 are often confused with structural building components classified elsewhere. Precast concrete building elements like beams, columns, and flooring/roofing slabs are classified here, while similar-looking prefabricated structural sections of cement, concrete, or artificial stone are found in 6810.99. A key distinction is that 681091 covers specifically 'building elements,' whereas 6810.99 is a broader basket category for other articles like pipes, tanks, and non-building structural items. Always verify if the product is designed for permanent incorporation into a building or civil engineering structure to confirm placement in 681091.
