High Purity Magnesia Refractory Shapes are custom-shaped refractory components with a magnesia (MgO) content of 95% or more, designed for specialized furnace zones such as ladle impact pads. These products are precision fired after shaping to maintain dimensional stability and withstand extreme thermal conditions. They fall under tariff item 6902.10.00 because they are refractory ceramic constructional goods containing more than 50% by weight of MgO.

Import Tips
• Ensure the MgO content is clearly documented in the commercial invoice to support classification under 6902.10.00
• Verify that the goods have been fired after shaping, as unfired or low-temperature processed articles are excluded from Chapter 69
• Consult the CBSA's advance ruling process if you are uncertain about the tariff classification
