Last updated: August 2026 dataPorcelain and china laboratory wares — crucibles, evaporating dishes, combustion boats, and machinery parts made from high-fired ceramic — serve critical roles in analytical chemistry, materials testing, and industrial process equipment. Japan leads US imports under this subheading, reflecting its advanced technical ceramics manufacturing base, with China and South Korea also significant suppliers. The US schedule separates general laboratory and chemical wares (6909114000) from machinery parts of porcelain or china (6909112000), a distinction that can affect both duty rates and classification under other chapters when the parts are imported as components of larger equipment. Importers should confirm whether specific articles meet the porcelain or china material standard, as non-porcelain technical ceramics classify under 6909.19.

For HTS purposes, porcelain and china are high-fired, vitrified, translucent ceramics typically based on kaolin, feldspar, and quartz. Articles made from stoneware, earthenware, alumina, silicon carbide, or other technical ceramic compositions that do not meet this definition classify under 6909.19 instead. The material composition — not the end use — is the primary classification driver, so manufacturer material certifications are useful supporting documents.
If the porcelain component is imported separately, it classifies under 6909.11 as a part or ware in its own right. When imported as an integral part of a complete instrument, GRI 1 and the relevant chapter notes for the instrument's heading may govern, potentially pulling the ceramic component into the instrument's classification. Importers should evaluate whether the ceramic article is presented with the instrument or separately, and consult a licensed customs broker when the facts are ambiguous.
