Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If simply sintered
Sintered-only tungsten sheets fall under 8101.97, excluded from this subheading per description.
If made from yttrium base with tungsten alloy
Chapter 81 headings prioritize predominant base metal; yttrium-tungsten shifts to 8112.
If coated for semiconductor wafer processing
Surface-coated tungsten sheets for semiconductor use classify as parts of apparatus in Chapter 85.

Import Tips & Compliance
• Provide thickness and width specs to distinguish from foil (<0.2mm), avoiding reclassification
• Include end-use statements if for defense; may qualify for special programs but requires ITN
