The HS code for medical devices is heading 9018, covering instruments and appliances used in medical, surgical, dental, and veterinary sciences. But for medical devices, the code is rarely what stops the shipment. The real barrier is regulatory: a device can be correctly classified and low-duty and still be refused at the border for lacking FDA clearance, CE marking under the MDR, or registration with the destination health authority, and the regulator can block release even after customs has cleared the entry. This guide gives the subheadings, the duty position, and the regulatory approval that actually decides whether the device lands.
Medical devices classify under Harmonized System heading 9018, instruments and appliances for medical, surgical, dental, and veterinary use. Common subheadings include 9018.11 for ECG machines, 9018.12 for ultrasound, 9018.31 for syringes, and 9018.90 for other instruments. The base duty is low or zero in major markets, but medical devices must also clear regulatory approval, such as FDA clearance or CE marking, which is a separate requirement from classification and duty.
What is HS 9018? Heading 9018 covers instruments and appliances used in medical, surgical, dental, or veterinary sciences, including electro-diagnostic apparatus and their parts and accessories.
What is HS 9018.90? Subheading 9018.90 covers other instruments and appliances not specified elsewhere in the heading, the catch-all line where many electro-medical and combination devices classify.
The 9018 Subheadings That Matter
Heading 9018 is wide, covering everything from a syringe to an MRI-adjacent diagnostic system. Classification depends on form, function, and shipment presentation. These are the lines that matter most in practice.
| Subheading | What It Covers |
|---|---|
| 9018.11 | Electrocardiographs (ECG machines) |
| 9018.12 | Ultrasonic scanning apparatus (ultrasound) |
| 9018.13 | Magnetic resonance imaging apparatus |
| 9018.19 | Other electro-diagnostic apparatus |
| 9018.31 | Syringes, with or without needles |
| 9018.32 | Tubular metal needles and needles for sutures |
| 9018.39 | Catheters, cannulae, and the like |
| 9018.90 | Other instruments and appliances |
Related headings matter too: X-ray, CT, and radiation apparatus classify under heading 9022, not 9018, and orthopaedic appliances, pacemakers, and hearing aids under 9021. Getting the heading right is the first step, because it drives both the duty and the regulatory pathway.

HS Code for Medical Devices: What Duty Does 9018 Pay?
At the base rate, low or nothing in many markets. Numerous countries apply a zero or low most-favoured-nation duty to medical devices under 9018, reflecting their essential nature, and free trade agreements can reduce it further. In the US, many 9018 lines are duty-free or carry only a low single-digit rate, and the EU often applies reduced rates. So the base duty is rarely the obstacle.
Two things can still add cost. Import VAT applies on the landed value in the EU, UK, and many markets, though some apply reduced or zero VAT to certain medical goods, and origin-based measures can stack: medical devices of Chinese origin entering the US, for example, can face Section 301 tariffs on top of the base rate. Building the full figure before shipping is what our landed cost guide covers. But for medical devices, the barrier is rarely cost.
The Real Barrier: Regulatory Approval, Not Duty
Classification and regulatory approval are separate systems. The HS code sets the duty; regulatory approval decides whether the device can legally enter and be sold at all. A medical device must satisfy the health regulator as well as customs, and the regulator can block release even after customs has cleared the entry.
Every major market gates medical devices behind its own approval regime, and the requirement is tied to the device’s risk class, not its HS code. The specifics vary, but the principle is universal:
- United States. The device must be legally marketed, holding FDA clearance through 510(k), a granted De Novo, premarket approval (PMA), or an exemption, and the US importing entity must be registered as the initial importer. A device that is not legally marketed cannot be imported, even for onward export.
- European Union. The device needs CE marking under the Medical Devices Regulation (MDR 2017/745), with Notified Body involvement for higher-risk classes and a designated authorised representative in the EU. Under the extended transition in Regulation (EU) 2023/607, eligible legacy Class III and implantable Class IIb devices may remain on the market until 31 December 2027, and other Class IIb, Class IIa, and Class I devices until 31 December 2028, where the conditions are met.
- Other markets. Registration with the national health authority is required, for example NMPA in China, PMDA in Japan, TGA in Australia, each with its own timeline and documentation.
The single most common reason a medical device is held is that it was not registered with the destination health authority before it arrived, or the importing entity did not hold the required medical device licence. And through 2026, customs authorities and health regulators are coordinating more closely, with less tolerance for thin importer structures. We set out how an importer of record carries these obligations on our importer of record for medical devices page.

The Boundary: 9018 vs 9021 vs 9022
Chapter 90 holds several medical headings, and putting a device in the wrong one changes both the duty and the regulatory treatment. Heading 9018 is for instruments and appliances used in medical, surgical, dental, or veterinary practice, the syringes, catheters, ECG and ultrasound machines. Heading 9021 covers orthopaedic appliances, artificial joints, hearing aids, pacemakers, and implants that stay with the patient. Heading 9022 covers X-ray, CT, and radiation-based imaging and therapy apparatus. In short, active instruments and diagnostics are 9018, implants and orthopaedic aids are 9021, and radiation-based imaging is 9022. The device’s function decides the heading, and radiation-emitting devices carry additional controls of their own.
Frequently Asked Questions
What is the HS code for medical devices?
Heading 9018 covers most medical, surgical, and dental instruments, with subheadings such as 9018.11 for ECG, 9018.12 for ultrasound, and 9018.31 for syringes. Imaging and implants sit in 9022 and 9021.
The exact subheading depends on the device and determines both the duty and the regulatory pathway.
Is HS code 9018 duty-free?
In many markets, at the base rate, yes or close to it, because medical devices often carry low or zero duty. Import VAT and measures such as Section 301 can still apply on top.
For medical devices, the duty is rarely the obstacle. Regulatory approval is what usually decides whether the shipment clears.
Do medical devices need FDA or CE approval to import?
Yes, in most markets. A device must be legally marketed, with FDA clearance in the US or CE marking under the MDR in the EU, and registered with the health authority.
Without that approval, the health regulator can block release even after customs has cleared the goods, so it must be in place before the device ships.
What is the difference between HS 9018, 9021, and 9022?
9018 covers active instruments and diagnostics like syringes and ultrasound. 9021 covers implants, artificial joints, and hearing aids. 9022 covers X-ray, CT, and radiation apparatus. Function decides the heading.
Getting the heading right matters because each carries different duty and regulatory treatment, and radiation devices face extra controls.
The HS code for medical devices is heading 9018, with the subheading set by the specific instrument. But the code is the easy part: for medical devices, regulatory approval, FDA clearance, CE marking, or health-authority registration, is what decides whether the device lands, and the regulator can block it even after customs clears. Get the classification, the registration, and the licence right together, and the device reaches the patient. Carra Globe manages all three as importer of record for medical devices worldwide.
