Product classification
HS code for Chimney pots: 6905.90
Ceramic chimney-pots, cowls, chimney liners, architectural ornaments and other constructional goods (excluding roofing tiles).
Classification of chimney pots under HS 6905.90
Chimney pots and related ceramic components are classified under HS code 6905.90. This classification is determined by the material composition and the specific application of the goods within the construction industry. Chapter 69 of the Harmonized System covers ceramic products, and heading 6905 is dedicated to ceramic roofing tiles, chimney-pots, cowls, chimney liners, architectural ornaments, and other constructional goods. While 6905.10 is specifically for roofing tiles, the subheading 6905.90 serves as the category for all other items listed in the heading. These products are typically manufactured from common clay or fireclay, which is shaped and then fired to achieve the necessary thermal resistance and structural integrity required for venting combustion gases. The classification remains consistent regardless of whether the ceramic is glazed or unglazed, provided it retains its character as a constructional ceramic component.

Codes often confused with 6905.90
Common mistake. Chimney pots are frequently misclassified under HS code 6810, which covers articles of cement, concrete, or artificial stone. If the pot is made of concrete rather than fired clay, it must be moved to Chapter 68. Additionally, metal chimney cowls or liners are often confused with ceramic ones; however, metal variants are classified under heading 7326 as other articles of iron or steel. Another common error is using 6904, which is reserved for ceramic building bricks, but chimney liners and pots are considered specialized constructional goods rather than standard bricks.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
