About HS Code 701690
This HS code covers multicellular or foam glass, a unique material known for its excellent thermal insulation, fire resistance, and compressive strength. It's produced by heating powdered glass mixed with a foaming agent, creating a closed-cell structure. In international trade, these products are primarily imported by construction companies, industrial insulation contractors, and specialized building material suppliers for applications requiring high-performance insulation, particularly in demanding environments like cryogenic facilities, flat roofs, and industrial pipelines. Exporters are specialized manufacturers of foam glass, often with proprietary production technologies. Key things to know include the material's R-value (thermal resistance), its resistance to moisture and chemicals, and its non-combustible properties, which make it a preferred choice over other insulation materials in specific scenarios. Its durability and environmental benefits (made from recycled glass) also contribute to its market appeal.
Products Under This Code
Foam glass insulation blocks, Multicellular glass panels, Cryogenic insulation shells, Foam glass roof insulation, Industrial pipe insulation, Foam glass paving blocks, Sound-absorbing foam glass
Real World Examples
Pittsburgh Corning FOAMGLAS, GLAPOR Foam Glass, Misapor Foam Glass, Poraver Foam Glass Granules, Geocell Foam Glass
Common Misclassification
Can be confused with other insulation materials like mineral wool (6806) or plastic foam (3921) if the "glass" composition isn't clearly identified, or with other pressed/moulded glass articles (7013, 7020) if its primary function as insulation is overlooked.
Products Classified Under 7016.90
Industry
This code belongs to the Automotive & Vehicles industry.
Trade Overview
Germany, the USA, and China are significant players in both the production and consumption of foam glass insulation products.
