Tungsten Carbide Tricone Drill Bit from China
A three-cone roller bit with tungsten carbide inserts containing over 0.2% tungsten by weight, used for earth boring in mining and construction. Classified under HTS 8207.19.30 for its high-alloy cutting edges that provide superior hardness against abrasive rock. Ideal for rotary drilling in soft to medium formations.

Import Tips
• Provide metallurgical analysis reports proving tungsten content to justify alloyed classification
• Avoid bundling with non-tool parts; ship as individual bits to prevent set classification issues
• Check for IADC code labeling, common for tricone bits, to support rock drilling end-use
