HS code for Molybdenum crucibles: 8102.99
Molybdenum, articles n.e.c. in heading no. 8102.
Classification of molybdenum crucibles under HS 8102.99
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.

Codes often confused with 8102.99
Common mistake. 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.
Top exporters and importers of HS 810299 (the code used for molybdenum crucibles), 2025
In 2025, the largest exporter of HS 810299 (the code used for molybdenum crucibles) in UN Comtrade data was China, with 34% of world exports; the largest importer in UN Comtrade data was Germany, with 19% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
