Chapter 69 covers ceramic products, including various refractory ceramic articles, ceramic building materials, laboratory ceramics, etc. The ceramic products of this chapter must be fired at high temperatures and have properties such as heat resistance and corrosion resistance. Refractory ceramic articles are mainly used in high-temperature industrial fields such as metallurgy, glass, and cement. Heading 6902 covers refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths. These articles have high refractoriness and can withstand high-temperature environments, and are often used for linings of industrial kilns, furnaces and other thermal equipment. The first 2 digits 69 represent Chapter 69 ceramic products; digits 3-4, 02, represent heading 6902 refractory bricks and similar refractory ceramic constructional goods; digits 5-6, 90, represent subheading 690290 other refractory bricks and refractory materials, i.e. other refractory ceramic articles other than those specifically named such as siliceous, clayey, or high-alumina. The goods are refractory bricks and refractory materials, but are not specifically named in 690210 to 690280 (such as siliceous, clayey, high-alumina, etc.), and therefore are classified under 690290. If they were articles of siliceous fossil meals or diatomite, they would be classified under 6901; if they were other ceramic articles, they would be classified under 6903, etc.

📝 Declaration Elements
Product name: The specific name of the declared goods, such as "other refractory bricks" or "refractory material articles", which must be consistent with the actual goods. Material: Main components, such as alumina, silicon carbide, zirconia, etc., with content percentages required. Refractoriness: The temperature at which the material withstands high heat without softening, usually expressed in °C, such as ≥1500°C. Use: Specific application scenarios, such as "used for linings of iron and steel smelting furnaces", "glass kilns", etc. Shape: The appearance of the article, such as brick shape, block shape, plate shape, irregular shape, etc., which must match the heading description. Brand: Manufacturer or brand name; if there is no brand, fill in "none". Specifications and dimensions: Dimensions such as length, width and height, e.g. 230mm×114mm×65mm, used to confirm whether they are standard bricks. Production process: Such as sintering, fusion casting, etc., affecting material properties and classification. Product name: other refractory bricks; Material: alumina 85%, silica 10%, others 5%; Refractoriness: ≥1700°C; Use: used for linings of iron and steel smelting furnaces; Shape: brick shape; Brand: none; Specifications and dimensions: 230mm×114mm×65mm; Production process: high-temperature sintering. Incorrectly classifying monolithic refractories (such as refractory mortar, castables) under 690290, when they should actually be classified under 3816. Failure to provide refractoriness or refractoriness below 1500°C, which may result in classification as other ceramic articles. Material description is too general and fails to provide specific chemical composition, leading to classification disputes.

⚠️ Declaring monolithic refractories as bricks, leading to classification errors.
Brand
Manufacturer or brand name; if there is no brand, fill in "none".
⚠️ Confusing brand with manufacturer, or failing to provide the Chinese translation.
Specifications and dimensions

🎯 Classification Logic
The core basis for classification is: 1. whether the goods are refractory ceramic articles; 2. whether the refractoriness is ≥1500°C; 3. whether they are bricks, blocks, tiles and similar constructional goods; 4. whether they are specifically named in 690210-690280. If none are satisfied, classify under 690290. 690210 Refractory bricks containing magnesium, calcium or chromium: 690210 specifically refers to refractory bricks containing magnesium, calcium or chromium, while 690290 covers other non-named refractory bricks. 690220 Siliceous refractory bricks: 690220 refers to siliceous refractory bricks (silica content ≥90%), while 690290 excludes siliceous ones. 690290 Other refractory bricks and refractory materials: This code is a residual code and applies to refractory ceramic articles not specifically named. 381600 Refractory cements, mortars and similar refractory materials: 3816 covers monolithic refractories, such as castables and refractory mortars, while 690290 covers shaped refractory articles. Is it clearly a refractory ceramic article? Does the refractoriness reach 1500°C or above? Is it in the shape of constructional goods such as bricks, blocks, tiles? Is it not specifically named in 690210-690280? Are articles of siliceous fossil meals or diatomite excluded?
