U.S. exports of laboratory, hygienic, and pharmaceutical glassware with low thermal expansion (borosilicate-type) (HS 701720) totaled $7.2M in July 2026.
Importers of Laboratory, Hygienic, and Pharmaceutical Glassware with Low Thermal Expansion (Borosilicate-Type) paid $859K in duties in July 2026 — an effective duty rate of 16% on $5.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Laboratory, Hygienic, and Pharmaceutical Glassware with Low Thermal Expansion (Borosilicate-Type) imports of $5.8M in July 2026 ran 21% above the year-to-date monthly average of $4.8M.
Last updated: July 2026 dataGlassware with a linear coefficient of thermal expansion not exceeding 5×10⁻⁶ per Kelvin — the defining specification of borosilicate glass — is the workhorse material for laboratory benchtops, pharmaceutical manufacturing, and hygienic processing equipment worldwide. Germany is the leading US supplier under this heading, a reflection of the country's historic dominance in borosilicate glass production under brands widely recognized in the scientific community. Mexico and Sweden are also significant sources, with Costa Rica and India rounding out the supplier base.

Heading 7017.20 is reserved for glass with a measured linear coefficient of expansion at or below 5×10⁻⁶/K across the 0–300 °C range — the technical threshold that characterizes borosilicate compositions. Glassware made from soda-lime or other higher-expansion glass that does not meet this specification falls under heading 7017.90 regardless of its laboratory or pharmaceutical application. Importers should obtain a material data sheet confirming the expansion coefficient.
Importers should check whether any antidumping or countervailing duty orders are active on laboratory glassware from specific countries. Scope determinations in past proceedings have sometimes turned on glass composition and end use, so verifying current order scope with CBP or a trade attorney before entry is advisable, particularly for high-volume shipments.
