U.S. exports of Laboratory, Hygienic & Pharmaceutical Glassware (SITC 66591) totaled $21.3M in August 2026.
Importers of Laboratory, Hygienic & Pharmaceutical Glassware paid $2.0M in duties in August 2026, an average duty rate of 12.80% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataBorosilicate and other chemically resistant glass articles designed for laboratory, hygienic, or pharmaceutical applications — including beakers, flasks, test tubes, and sterile containers — are classified here based on their specialized end-use design rather than material alone. These goods are a critical input for pharmaceutical manufacturing, clinical diagnostics, and research institutions, where dimensional precision and chemical inertness are procurement specifications as important as price. FDA oversight may apply when pharmaceutical glassware is imported as a component of a drug delivery system or medical device, adding a regulatory layer beyond standard customs clearance.

FDA oversight is triggered when glassware is imported as a component of a drug product, drug delivery system, or medical device — for example, glass vials pre-filled with a drug substance or glass syringes classified as medical devices. Standalone laboratory glassware for general research use typically does not require FDA admissibility review, but importers should confirm the intended use and consult a licensed customs broker or regulatory counsel when the end use is pharmaceutical or clinical.
Laboratory glassware is distinguished by design features that reflect its specialized function: calibration markings, chemical resistance ratings (typically borosilicate or quartz glass), sterility requirements, and dimensional tolerances specified in standards such as ISO or ASTM. Ordinary household glass articles lacking these features would not qualify for this heading even if superficially similar in shape.
