HS Code 69.02 – Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; other than those of siliceous fossil meals or similar siliceous earths

HS code 6902 is a 4-digit heading in the Harmonized System that covers: Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; other than those of siliceous fossil meals or similar siliceous earths. Heading 6902 covers refractory bricks, blocks, tiles, and similar refractory ceramic constructional goods, explicitly excluding those made of siliceous fossil meals or similar siliceous earths (which fall under 6901). The defining characteristic here is 'refractory,' meaning these ceramic products are designed to withstand extremely high temperatures without deforming, melting, or degrading. They are crucial for lining furnaces, kilns, incinerators, and other high-temperature industrial equipment in sectors such as metallurgy, glass manufacturing, cement production, and petrochemicals. This heading encompasses a vast array of materials like fireclay, high-alumina, magnesia, silica, and silicon carbide ceramics, all chosen for their heat-resistant properties. The scope is confined to 'constructional goods,' meaning items used for building or lining structures, as opposed to smaller, non-constructional industrial ceramic articles (covered in 6903). For trade compliance professionals, understanding the specific refractory properties and material composition is vital for accurate classification, impacting tariffs, anti-dumping duties, and technical regulations. This heading is central to Chapter 69's focus on industrial ceramics, representing the workhorses of high-temperature processes globally, with a long history of enabling industrial development through robust thermal management.

Fireclay bricks, high-alumina refractory blocks, magnesia-carbon bricks, silica refractory tiles, chrome-magnesite bricks, silicon carbide kiln furniture (constructional), mullite refractory shapes, zirconia refractory blocks, insulating firebricks (non-diatomite), blast furnace bricks, glass furnace lining tiles, cement kiln liners, steel ladle bricks, tundish lining segments, coke oven bricks, ceramic burner blocks, refractory furnace arch bricks, heat-resistant ceramic plates, ceramic hot face lining bricks, basic refractory bricks.

Misclassification often occurs when the 'refractory' nature is not fully assessed, leading to confusion with general building bricks (6904) or even non-ceramic refractory materials (e.g., carbon blocks in 6815). Another common error is failing to exclude items of siliceous fossil meals, which belong in 6901. Furthermore, smaller, non-constructional refractory ceramic articles like crucibles or nozzles might be incorrectly placed here instead of 6903. The key is that 6902 covers ceramic *constructional goods* that are *refractory* but *not* made from siliceous fossil meals.

In 2025, the top exporters of HS code 6902 in UN Comtrade data were China ($1.6B, 40% of world exports), Germany ($465M) and Austria ($213M). World exports came to about $4.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 6902 in UN Comtrade data were India ($329M, 7.8% of world imports), the United States ($317M) and Indonesia ($244M). World imports came to about $4.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 6902 is a 4-digit heading under Chapter 69 of the Harmonized System. The first 2 digits (69) identify the chapter, and digits 3-4 (02) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
