Frequently Asked Questions
What are the primary customs inspection risks when importing ultrasound machines under HTS 9018.12?
The primary risk is detention for verification of the device's intended medical use versus non-medical industrial or veterinary applications, as classification and duty rates differ. Customs may also require proof of FDA approval or equivalent national health authority clearance, and physically inspect for proper shielding and compliance markings to ensure it is not a restricted dual-use item.
What additional costs, beyond the unit price and standard freight, are typically incurred when importing ultrasound machines under HTS 9018.12?
Importers of ultrasound machines must budget for the U.S. Merchandise Processing Fee (MPF), which is 0.3464% of the entered value (minimum $27.23, maximum $528.33). You will also likely owe Section 301 tariffs of 7.5% on the value of the apparatus, as these medical devices originating from China are not currently on the approved exclusion list.
Medical Device Compliance for Ultrasound Machines
Ultrasound machines imported into the United States are regulated as medical devices by the FDA. Importers must ensure the model is listed with the FDA and, for diagnostic systems, has a 510(k) clearance or PMA approval. Shipments typically require an FDA device registration number and may be subject to detention for review under PNs 99-41 and 99-42. Compliance with FDA's Unique Device Identification (UDI) system rules, including direct marking requirements, is also mandatory for most devices.
