HS Code for Molybdenum crucibles

Molybdenum crucibles are classified under HS code 810299, which serves as the residual category for articles of molybdenum not elsewhere specified. Molybdenum is a base metal covered under heading 8102. The classification logic dictates that semi-finished forms like bars, rods, and plates are classified in subheadings 8102.94 through 8102.96. However, once the molybdenum has been manufactured into a specific finished article, such as a crucible used for high-temperature melting or sintering, it falls into the "other" category of 8102.99. These crucibles are valued for their high melting point and resistance to corrosion by molten glass and metals. Because they are made of base metal rather than ceramic or graphite, they must be classified according to their constituent material in Chapter 81.

Common Misclassification

Molybdenum crucibles are often misclassified under HS code 6903, which covers refractory ceramic goods. While they perform similar functions in high-heat environments, 6903 is strictly for non-metallic mineral products. Another common error is using 8102.95, which is intended for molybdenum plates and sheets; while crucibles are made from these materials, the finished article status moves them to 8102.99.

FAQ

What is the HS code for molybdenum crucibles?

The HS code for molybdenum crucibles is 8102.99, covering finished articles of molybdenum.

Why are these not classified as laboratory ware in Chapter 70 or 69?

Classification is determined by the material of construction. Since these are made of the base metal molybdenum, they are governed by the notes of Section XV and Chapter 81.
