Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of alloy steel
Alloyed ductile fittings beyond plain iron/steel move to specialized alloy headings.
If for high-temperature steam applications
Heat-resistant cast fittings classify under other non-ductile or specialized casts.
If sold as flywheel pulleys
Rare dual-use as mechanical transmission parts shifts to flywheel classification.

Import Tips & Compliance
• Specify groove type (e.g
• Victaulic Style 77) to match US standards and avoid rejection
• Declare nominal sizes accurately; oversize caps may classify as flanges under 7307.91
• Include EPDM gasket compatibility notes if supplied separately to prevent set duties
