Export controls and used semiconductor equipment, an overview

Semiconductor manufacturing equipment is one of the most tightly controlled categories of industrial goods, and those controls do not stop applying when a tool is old, used or bought for teaching. A refurbished etcher, deposition tool or implanter can need an export licence, a sanctions check or an end-use statement before it leaves the country, depending on what it is, where it is going and who will use it.

This post gives a general overview of how export controls apply to used semiconductor equipment, from the perspective of a buyer or seller in the EU. It is not legal advice.

Rules change often, and each shipment needs its own assessment against the current regulations, ideally with your organisation's export control officer or a specialist adviser.

Why used tools are controlled at all

Export controls on semiconductor equipment exist because the same tools that make research devices and commercial chips can contribute to military and strategic programmes. The controls are written around what the equipment can do, not how old it is or what the seller paid for it. A tool built decades ago can still fall under a control entry if it meets the technical parameters in that entry.

In practice, many older single-wafer tools used in teaching cleanrooms fall outside the listed controls. But "many" is not "all", and the assessment has to be made tool by tool, configuration by configuration. Sanctions and end-use rules can also apply to goods that are not listed at all.

The main rules that usually apply in the EU

For a shipment leaving the European Union, the rules that most often matter are:

• The EU Dual-Use Regulation, Regulation (EU) 2021/821. Its Annex I lists controlled items, based largely on the multilateral Wassenaar Arrangement lists. Category 3 covers electronics, and its section 3B covers test, inspection and production equipment, including several types of semiconductor manufacturing equipment. If a tool matches an entry, exporting it outside the EU needs a licence.
• National measures. The regulation allows member states to add controls. The Netherlands, for example, has had a national licence requirement for certain advanced semiconductor manufacturing equipment since September 2023, and the scope of such measures has been changed since. In the Netherlands, licences are issued by the CDIU, part of Dutch Customs.
• Catch-all controls. Under Article 4 of the regulation, even an unlisted item needs a licence if the exporter has been informed by the competent authority that it is or may be intended for certain sensitive end uses, such as weapons of mass destruction programmes or military end use in a country under an arms embargo. An exporter who is aware of such an intended use must notify the authority, which then decides whether a licence is required.
• Sanctions. EU restrictive measures, such as those against Russia under Regulation (EU) No 833/2014, prohibit or restrict the export of many goods to listed countries and persons, often well beyond the dual-use list. Screening the buyer, end user and any intermediaries against sanctions lists is a separate step from classification.

Movements between EU member states are generally free of licence requirements for most dual-use items, though some of the most sensitive categories still need authorisation.

US rules can follow a tool abroad

The US Export Administration Regulations (EAR) can apply to items outside the United States. A tool made in the US, or one containing more than a threshold share of controlled US-origin content, can stay subject to the EAR when it is re-exported from Europe. Recent US rules on semiconductor equipment have also widened the reach of the EAR to some foreign-made items and to certain end users.

For a buyer or seller in Europe, this means a US-built tool may need a check against the Commerce Control List and US end-user lists, in addition to the EU assessment. Where the EAR may apply, specialist advice is usually worth the cost.

Classification: the first and hardest step

Everything else depends on classification: deciding whether the tool, and any software or technology shipped with it, matches an entry on a control list. Useful inputs are:

• Manufacturer, model and exact configuration, including options, chamber types and installed upgrades.
• Technical parameters that control entries refer to, taken from the original specification and the tool's current state.
• Any classification the manufacturer has published, which can be a starting point but does not replace your own assessment, especially for modified tools.
• Software and documentation. Control software, recipes and technical manuals can be controlled separately from the hardware.

Customs tariff codes (HS or CN codes) are not the same as export control classifications. Both are needed for an international shipment, and one cannot be derived from the other.

What buyers and sellers should prepare

Buyers

If you are buying a used tool for export, a seller who takes compliance seriously will ask you for information. Expect requests for:

• Full name and address of the buyer, consignee and end user, if they differ.
• An end-use statement describing what the tool will be used for and where it will be installed, signed by the end user.
• Assurance against re-export or transfer without the required authorisation.
• Supporting information for a licence application, if one is needed.

Providing this early shortens lead time. Licence decisions take weeks or longer, and a shipment cannot leave until the licence is granted. A university buyer can usually get help from its own export control or research security office.

Sellers

If you are selling or relocating a tool across a border, prepare:

• A written classification of the tool, with the reasoning and the date.
• Sanctions and restricted-party screening records for every party to the transaction.
• The end-use statement and any licence, filed with the shipment records.
• Commercial documents, packing lists and the customs classification for the freight forwarder.
• Records kept for the period your national law requires.

Build the compliance step into the project plan from the first enquiry. Discovering a licence requirement after the tool has been crated can leave it standing in a warehouse for months.

Controls continue after delivery

Export rules do not end at the destination's loading dock. An end-use statement usually commits the buyer not to re-export or transfer the tool without authorisation, and a licence may set conditions on where and how the tool is used. If the tool later moves to another country, or is sold to a different end user, that is a new export and needs its own assessment.

Spare parts, replacement controllers and remote software updates can also be controlled, sometimes under the same entry as the tool. For a lab that relies on support from abroad, it is worth asking at purchase how parts and service will reach you.

What we can do

We classify the tools we sell on the basis of their configuration, screen the parties to each sale, apply for a licence when one is needed and prepare the documentation a shipment needs. We do not give legal advice. Our approach is set out on our export compliance page and in quality and compliance. For the physical side of an international shipment, see de-installation and crating.
