Pyroceram Glass-Ceramic Casserole Dish from China

A non-glazed kitchenware casserole dish made from lithium aluminosilicate glass-ceramic, exceeding 75% crystallinity with β-quartz solid solution as the predominant phase. It features a low linear coefficient of expansion (≤10 x 10-7/K from 0-300°C), transparency, haze-free clarity, and high IR transmittance (>75% at 2.5 microns on 3mm sample), classifying it under HTS 7013.10.10.00 for specialized glass-ceramic kitchenware.

Import Tips

Provide lab certification confirming >75% crystallinity, β-quartz phase, low thermal expansion, haze-free transparency, and IR transmittance specs to justify 7013.10.10.00 classification

Ensure non-glazed finish and kitchenware end-use documentation; glazed versions shift to other subheadings

Avoid misclassification as common glassware (7013.91); test reports prevent audits and penalties
