Products classified under HTS 8543.30.90.40
Sacrificial Magnesium Hull Anode
A consumable magnesium anode designed for cathodic protection of marine vessel hulls during electrolysis in saltwater environments. It attaches to the ship's hull and corrodes preferentially to protect the steel structure. Classified under HTS 8543.30.90.40 as a magnesium anode for electrolytic processes.
Magnesium Ribbon Anode for Electrolysis Lab
High-purity magnesium ribbon anode used in laboratory electrolysis experiments to provide sacrificial anode protection and generate hydrogen gas. Wound on spools for easy handling in educational or research settings. Falls under HTS 8543.30.90.40 specifically as magnesium anodes for electrolytic functions.
Extruded Magnesium Anode Rod for Water Heaters
Cylindrical extruded magnesium anode rod installed in domestic water heaters to prevent tank corrosion through electrolytic protection. Typically 3/4-inch diameter with steel core for mounting. HTS 8543.30.90.40 covers these as functional magnesium anodes for electrolysis.
Magnesium Bracelet Anode for Offshore Platforms
Circular bracelet-style magnesium anode with cable attachment for cathodic protection of offshore oil platform legs and pipelines. Designed for high-current output in seawater electrolysis. Classified under HTS 8543.30.90.40 as specialized magnesium anodes.
High-Purity Magnesium Slab Anode for Electroplating Tanks
Rectangular slab magnesium anodes (99.9% purity) used in industrial electroplating tanks to maintain electrolyte balance and protect tank linings. Suspended via stainless steel hooks. HTS 8543.30.90.40 specifically for magnesium anodes in electrolytic apparatus.
