HS Code for Laboratory porcelain

Laboratory porcelain is classified under HS code 6909.11 because it falls within Chapter 69, which covers ceramic products. Specifically, heading 6909 is reserved for ceramic wares designed for laboratory, chemical, or other technical uses. The subheading 6909.11 is designated for articles made of porcelain or china. To qualify for this classification, the item must possess high resistance to chemical attack and thermal shock, characteristics essential for laboratory environments. Unlike decorative or domestic ceramics, these items are manufactured with precise tolerances and specific material compositions to withstand extreme temperatures and corrosive substances. The classification logic follows the material composition (ceramic) and the intended technical application, distinguishing it from general-purpose ceramic containers or household tableware. Furthermore, the Harmonized System distinguishes between porcelain (a translucent, vitrified ceramic) and other types of stoneware or earthenware, which would fall under 6909.12 or 6909.19. The technical nature of these goods is defined by their use in scientific research, industrial analysis, or chemical processing, where standard ceramic materials would fail due to porosity or lack of chemical inertness.

Products Included

• Porcelain crucibles and covers
• Evaporating dishes and basins
• Combustion boats
• Mortars and pestles for laboratory use
• Spatulas and filter plates
• Porcelain funnels (e.g., Buchner funnels)
• Crucible supports and triangles

Common Misclassification

Laboratory porcelain is frequently confused with laboratory glassware classified under HS code 7017. While they serve similar functions, the material composition is the primary determinant. Additionally, porcelain items intended for domestic use or general storage are classified under 6911.10 (tableware) or 6914.10 (other ceramic articles). It is crucial to verify if the item is made of porcelain or another ceramic material like stoneware (6909.12), as the duty rates and regulations may differ.

FAQ

What is the HS code for laboratory porcelain?

The specific HS code for laboratory porcelain is 6909.11, which covers ceramic wares for laboratory, chemical, or other technical uses made of porcelain or china.

Does this code include porcelain used in medical clinics?

Yes, as long as the porcelain is used for technical or chemical analysis purposes, it falls under 6909.11. However, porcelain dental fittings or medical instruments made of other materials would be classified in Chapter 90.
