Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If articles like preformed pipe sections or custom shapes
Mixtures and articles beyond bulk/sheets/rolls/batts fall under the 'other' subheading for fabricated mineral insulating products.
If made from glass wool fibers instead of rock/slag
Glass wool variants are classified in Chapter 70 for glass fibers and articles, separate from mineral wools of Chapter 68.
If faced with paper or cardboard backing
Paper-covered insulating materials may shift to Chapter 48 if the paper component dominates, per chapter exclusions.

Import Tips & Compliance
• Include noise reduction coefficient (NRC) test reports and fiber diameter specs to substantiate sound-insulating claims during import valuation
• Label clearly as 'non-combustible mineral wool' and avoid packaging resembling finished articles of chapter 94 to prevent reclassification
