HS Code 6906.00 – Ceramic pipes, conduits, guttering and pipe fittings

HS code 6906.00 is the 6-digit subheading for ceramic pipes, conduits, guttering and pipe fittings. It is used for vitrified clay pipes, ceramic drainage conduits, terracotta guttering, ceramic pipe bends and ceramic pipe junctions.

What HS 6906.00 covers

This code covers ceramic pipes, conduits, guttering, and pipe fittings, which are essential for various infrastructure and building applications. These products are known for their exceptional durability, resistance to corrosion, and longevity, making them ideal for drainage, sewage systems, and protecting electrical cables underground. They are primarily traded by civil engineering contractors, municipal suppliers, and specialized plumbing and drainage material distributors. Key characteristics include their high compressive strength, chemical inertness, and environmental benefits compared to plastic alternatives in certain applications. The manufacturing process, often involving vitrification, ensures a robust and impermeable product suitable for demanding environments and long-term service.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
