About HS Code 731814

This HS code specifically covers self-tapping screws made of iron or steel, which are engineered to tap their own mating thread when driven into a pre-drilled hole in materials such as metal, plastic, or sometimes wood. This innovative design eliminates the need for a separate tapping operation, significantly streamlining assembly processes across various manufacturing and construction industries. International trade is robust, with importers including the automotive industry, electronics manufacturers, sheet metal fabricators, construction companies, and hardware distributors. Exporters are typically specialized fastener manufacturers with advanced precision engineering capabilities. Key factors in trade include the screw's specific thread form (e.g., sheet metal, machine screw thread), point type (e.g., sharp point, blunt point, self-drilling), head style, material hardness, and corrosion resistance, all critical for optimal performance in diverse applications.

Products Under This Code

Sheet metal screws, self-drilling screws (Tek screws), thread-forming screws, thread-cutting screws, drywall screws (often self-tapping), plastic screws, wafer head self-tappers

Real World Examples

SFS intec self-drilling screws, ITW Buildex Tek screws, Phillips II self-tapping screws, Hilti self-tapping anchors

Common Misclassification

Often confused with 731812 (wood screws) if used in wood, or 731815 (other threaded screws) if their self-tapping capability is not explicitly recognized, or even 731700 (nails) due to similar applications but different fastening mechanisms.

EU Regulatory Requirements

This product falls under the Carbon Border Adjustment Mechanism (CBAM). Importers to the EU must declare embedded carbon emissions and purchase CBAM certificates.

Products Classified Under 7318.14

Industry
