Products classified under HTS 2607.00.00.30
Zinc-Lead Sulfide Concentrate
A mineral concentrate derived from roasting and flotation of lead-zinc ores, containing significant zinc content as zinc sulfide (sphalerite). Classified under HTS 2607.00.0030 due to its primary zinc content within lead ores and concentrates. The zinc assay is reported statistically without deductions per chapter notes.
Sphalerite-Bearing Lead-Zinc Ore Concentrate
Concentrate from sphalerite-rich lead-zinc deposits, with zinc as the principal valuable component alongside galena. Falls under HTS 2607.00.0030 for lead ores where zinc content is statistically reported. Meets definitions for unrefined ores with mixed metal sulfides.
Mixed Galena-Sphalerite Flotation Concentrate
Flotation byproduct from polymetallic lead-zinc mines, reporting zinc content under lead ore concentrates. HTS 2607.00.0030 captures the zinc portion per statistical notes on assay quantities. Used in smelting for dual metal recovery.
Roast-Reduced Zinc-Lead Concentrate
Partially roasted concentrate from lead-zinc ores retaining reportable zinc content. Classified in HTS 2607.00.0030 as lead ores with zinc statistical breakout. Not fully calcined, preserving sulfide zinc characteristics.
Carbonate-Hosted Lead-Zinc Ore Concentrate
Concentrate from sedimentary lead-zinc deposits like those in Ireland or Australia, with zinc content in smithsonite and cerussite. HTS 2607.00.0030 for lead ores reporting zinc statistically. Suitable for hydrometallurgical zinc recovery.
Mississippi Valley Type Zinc-Lead Concentrate
Concentrate from MVT deposits (e.g., Red Dog, Alaska), emphasizing zinc content within lead ore matrix. Fits HTS 2607.00.0030 per hierarchy for lead ores with zinc. High-grade for modern smelters.
Kipushi-Type Copper-Lead-Zinc Ore Concentrate
Polymetallic concentrate from Kipushi-style deposits with reportable zinc in lead fraction. HTS 2607.00.0030 captures zinc content despite copper presence. Processed via selective flotation.
Broken Hill Style Lead-Zinc Concentrate
Sulfide concentrate mimicking Broken Hill (Australia) ores, with zinc sulfide prominent in lead ore product. Under HTS 2607.00.0030 for zinc content reporting. Iconic for silver byproduct credits.
