Rhenium Superalloy Scrap
Machining turnings and clippings from nickel-rhenium superalloys used in turbine blades, with rhenium as the key recovery element. Falls under HTS 8112.41.10.00 as rhenium waste and scrap since rhenium content defines its value despite alloy form. Recovered for aerospace and jet engine manufacturing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nickel content exceeds rhenium significantly
Nickel waste and scrap in Chapter 75 takes precedence when nickel is the base metal by weight.
If in wrought form like finished rhenium sheets
Wrought rhenium articles or semi-finished products classify under 8112.12, not waste.
If alloyed with iron and classified as ferrous scrap
Ferrous alloy scraps with rhenium additions may fall under Chapter 72 based on iron predominance.

Import Tips & Compliance
• Submit detailed chemical analysis showing rhenium as principal metal to distinguish from nickel alloy scrap under 7503
• Declare as non-hazardous if clean turnings; contaminated scrap requires waste manifests under RCRA

Rhenium Medical Imaging Foil Scrap
Quality rejects and trim scrap from rhenium foil used in CT scanner anode targets. Under HTS 8112.41.10.00 as rhenium waste and scrap from medical device production. Recovered for high-purity refoil production.
Rhenium Catalyst Waste
Spent rhenium-impregnated catalyst residues from petroleum refining processes, containing recoverable rhenium metal. Classified under HTS 8112.41.10.00 as waste and scrap of rhenium due to its primary rhenium content exceeding other metals and being unsuitable for direct use. This scrap is typically recycled to extract rhenium for reuse in high-performance alloys.
