SITCSection 7
U.S. exports of integrated circuit amplifiers (SITC 77646) totaled $119.3M in July 2026.
Importers of Integrated Circuit Amplifiers paid $985K in duties in July 2026 — an effective duty rate of 43% on $2.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAmplifier ICs — including operational amplifiers, audio amplifiers, RF amplifiers, and instrumentation amplifiers — are critical signal-conditioning components used across telecommunications, medical devices, automotive electronics, and industrial instrumentation. Unlike discrete transistor-based amplifiers, these monolithic devices integrate gain stages, biasing, and sometimes filtering on a single chip, which can complicate classification when the amplifier function is embedded within a larger mixed-signal IC. Section 301 measures apply to amplifier ICs of Chinese origin, and importers should verify whether any product-specific exclusions remain active.

If an IC contains an amplifier stage but its primary commercial function is processing, memory, or another operation, it may be classified under the heading corresponding to that principal function rather than as an amplifier. The key test is the essential character of the device as documented in the manufacturer's specifications and intended end-use.
Standard entry documentation includes a commercial invoice with the manufacturer's part number, country of origin, and a description sufficient to confirm the IC's function. For shipments from China, importers must also account for Section 301 classification and any applicable exclusion certificates. High-value or high-volume shipments may warrant a formal entry rather than an informal entry.
