U.S. exports of chromatographs & electrophoresis instruments (HS 902720) totaled $28.5M in July 2026.
Importers of Chromatographs & Electrophoresis Instruments paid $1.7M in duties in July 2026 — an effective duty rate of 11% on $15.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataGas chromatographs (GC), liquid chromatographs (LC/HPLC), and electrophoresis systems are foundational analytical tools for pharmaceutical quality control, environmental testing, food safety, and life-sciences research. The US tariff schedule is unusually granular here, with separate 10-digit lines for electrical gas chromatographs (9027205050), electrical liquid chromatographs (9027205060), electrical electrophoresis instruments (9027205030), and their non-electrical counterparts. Sweden leads US import supply — reflecting the global dominance of Swedish life-science instrument manufacturers — followed by Germany and Japan. Importers should be aware that combination GC-MS systems may require classification analysis to determine whether the chromatograph or the mass spectrometer function is principal.

A hyphenated GC-MS system presents a classification choice between heading 9027.20 (chromatographs) and 9027.81 (mass spectrometers). CBP generally applies GRI 3(b) to classify the system by the component that gives it its essential character, which in most integrated GC-MS instruments is the mass spectrometer function. A binding ruling is advisable for high-value systems where the duty difference is material.
Electrical liquid chromatographs (9027205060) use electronic detection, data acquisition, and control systems — covering virtually all modern HPLC instruments. Non-electrical liquid chromatographs (9027208060) would cover gravity-fed or purely mechanical column systems without electronic components, a category rarely imported today. Misclassifying a modern HPLC as non-electrical is a common error that can trigger CBP scrutiny.
