Automotive Head Gasket
A multi-layer steel gasket with elastomeric coatings used to seal the cylinder head to the engine block in internal combustion engines. It falls under HTS 8484.10.00.00 due to its construction from two or more layers of metal sheeting combined for high-pressure sealing in automotive applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported as part of a complete engine assembly
Engine gaskets supplied as integral parts of engines are classified with the engine under Chapter 84.
If primarily rubber with minimal metal reinforcement
Rubber gaskets or those where rubber is the essential character fall under Chapter 40 headings.
If single layer metal gaskets without composite materials
Simple gaskets of a single metal layer are classified separately from multi-layer composites.

Import Tips & Compliance
• Verify gasket composition via material certificates to confirm multi-layer metal construction for 8484.10 classification
• Include automotive OEM specifications in documentation to avoid reclassification as simple metal washers
• Watch for country-of-origin rules; many head gaskets from Asia face standard MFN duties around 2.5%
