Porcelain Crucible for Laboratory Use
A high-purity porcelain crucible designed for melting and heating substances in chemical laboratories, fired after shaping to achieve low water absorption and high thermal resistance. It falls under HTS 6909.19.50.95 as ceramic ware specifically for laboratory and chemical uses, distinct from common tableware. The translucent body ensures precise observation during experiments.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not fully fired after shaping or made from unfired ceramic pastes
Unfired or lowly processed ceramic articles fall under heading 6903, outside Chapter 69's fired products scope.
If featuring decorative motifs primarily for ornamental display rather than functional lab use
Ceramic articles with significant artistic elements are classified in 6914 as decorative wares, not technical uses.
If constructed primarily from glass-ceramic composites
Glass-ceramic labware shifts to Chapter 70, as it combines glass and ceramic properties beyond pure fired ceramics.

Import Tips & Compliance
• Verify firing temperature exceeds 800°C and provide lab test results for water absorption under 0.5% to confirm porcelain classification
• Include certificates of chemical resistance and thermal shock testing to avoid reclassification as common wares
• Label clearly as 'laboratory use only' to prevent misclassification into Chapter 69 exclusions like tableware
