c82736 · 1998-12-29 — The tariff classification of refractory cathode blocks from Germany.
The subject merchandise is cathode blocks, designated as "BN" and "5BGN," which are also known in the industry as "bottom blocks" and "carbon blocks." They are specially constructed for the lining of aluminum reduction furnaces known as "cells" or "pots." It is stated that the BN blocks and the 5BGN blocks have average crystallinity contents of 68.3 percent and 53.9 percent, respectively. These blocks are formed into a mixture of which the BN block is made from a combination of petroleum coke with a pitch binder, while the 5BGN block is made from 100 synthetic graphite with a pitch binder.…
