HS Code for Graphite refractories
View full HS code detailsGraphite refractories are classified under HS code 6903.10 as refractory ceramic goods containing more than 50% by weight of free carbon. This classification is determined by the material's ability to withstand high temperatures and its chemical composition. Unlike standard ceramic goods, these items are specifically designed for metallurgical and industrial furnace applications where high thermal conductivity and resistance to chemical erosion are required. The 50% threshold for free carbon is a critical technical requirement for this specific subheading. If the carbon content is lower, or if the product is a brick or block of a type used for structural masonry, different codes within Chapter 69 would apply. The classification follows the guidelines for Chapter 69, which distinguishes between refractory goods (those capable of resisting temperatures above 1,500 degrees Celsius) and ordinary ceramic ware. Because these products are shaped into specific industrial components like crucibles or nozzles, they are classified under 6903 rather than the raw material headings.
Products Included

- Refractory nozzles containing >50% carbon
- Graphite retorts and stoppers
- Refractory plugs for industrial furnaces
- Carbon-bonded ceramic refractory shapes
Common Misclassification
These products are often confused with HS code 6815.10, which covers non-electrical articles of graphite or other carbon. The difference is that 6903.10 is specifically for fired ceramic refractory goods, whereas 6815 is for non-ceramic carbon articles. Another common error is using 6902.10, which is reserved for refractory bricks and blocks; 6903 is the correct heading for other shapes like crucibles and tubes. Importers must verify the carbon percentage to ensure the product exceeds the 50% threshold required for 6903.10.
FAQ
What is the HS code for graphite refractories?
