Last updated: September 2026 dataDefined by a linear coefficient of thermal expansion not exceeding 5×10⁻⁶ per Kelvin across 0–300°C, this heading captures borosilicate-type kitchen and table glassware — the technical specification that underpins brands like Pyrex and similar heat-resistant cookware. China is the leading supplier, but Portugal is a notable second-ranked source, reflecting the presence of major European borosilicate glass manufacturers with significant US export programs. The schedule separates pressed-and-toughened articles (7013421000) from other pieces, then stratifies the remainder by unit value across three bands.

Classification under 7013.42 requires demonstrating that the glass has a linear coefficient of thermal expansion not exceeding 5×10⁻⁶ per Kelvin in the 0–300°C range. Importers should obtain a manufacturer's material specification sheet or third-party laboratory test report confirming this property. Without such documentation, CBP may reclassify the goods under the residual 7013.49 heading.
The pressed-and-toughened subheading (7013421000) is a distinct 10-digit line with its own rate, separate from the value-banded lines for other low-expansion kitchen glassware. Importers should verify the manufacturing process — pressing followed by thermal toughening — is accurately described on entry documentation, as the duty rate may differ from the value-band lines.
