HS-6 · Subheading
690320
Refractory ceramic goods; containing by weight more than 50% of alumina or of a mixture or compound of alumina and of silica, excluding those of siliceous fossil meals or similar earths
Heading 6903 — Ceramic goods; (e.g. retorts, crucibles, muffles, nozzles, plugs, supports cupels, tubes, pipes, sheaths, rods and slide gates) excluding those of siliceous fossil meals or of similar siliceous earths
Chapter 69: Ceramic products
Plain-language overview
Use HS-6 690320 when importing or exporting refractory ceramic goods that contain over 50% alumina. An example would be a shipment of alumina-based crucibles used in metal casting.
This code specifically applies to products like ceramic tubes and rods designed to withstand high temperatures, distinguishing them from other ceramic items that may not have the same alumina content. For instance, HS-6 690310 covers refractory ceramic goods with lower alumina content.
When classifying under this code, consider the end-use of the product. Refractory ceramics are essential in industries like metallurgy and glass manufacturing, where durability under extreme conditions is crucial.
If your goods are primarily made of siliceous materials or fossil meals, they would not fall under this code and may instead be classified under different headings. Always check the specific material composition to ensure correct classification.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of products are classified under HS-6 690320?
- HS-6 690320 includes refractory ceramic goods like crucibles, tubes, rods, and nozzles that contain more than 50% alumina.
- How can I tell if my ceramic product fits under this code?
- Check the material composition; if it contains over 50% alumina and is designed for high-temperature use, it likely falls under HS-6 690320.
- What should I do if my product has siliceous materials?
- If your ceramic goods contain siliceous fossil meals or similar materials, they do not qualify for HS-6 690320 and may need classification under a different code.
- Is there a difference between HS-6 690320 and HS-6 690310?
- Yes, HS-6 690310 covers refractory ceramics with lower alumina content, while HS-6 690320 is for those with more than 50% alumina.
- Can I use HS-6 690320 for ceramics used in electrical insulation?
- Only if those ceramics contain over 50% alumina and are designed for high-temperature applications; otherwise, they may need a different classification.
- What industries commonly use products classified under HS-6 690320?
- Industries such as metallurgy, glass manufacturing, and ceramics production frequently use refractory ceramic goods classified under this code.
- How do I verify the alumina content in my ceramics?
- You may need to conduct laboratory testing or consult with your supplier to determine the alumina content accurately.
- What packaging requirements should I consider for HS-6 690320 products?
- Ensure that your packaging can withstand high temperatures and protect the ceramics from damage during transport.
