Importing machinery from China into Great Britain involves more than arranging freight and paying customs duty.
For products such as power tools, CNC machinery, presses, construction machinery and other industrial equipment, the importer must consider two separate but connected processes:
customs clearance, primarily handled through HMRC and the Customs Declaration Service (CDS), and product compliance, which may involve the Office for Product Safety and Standards (OPSS), Trading Standards, the Health and Safety Executive (HSE) or another relevant enforcement authority.
Understanding the difference is important because there is no general UK system where every importer uploads a CE or UKCA technical file before the machinery is allowed to enter the country.
This article explains how the process works in Great Britain, meaning England, Scotland and Wales. Different arrangements apply in Northern Ireland.
1. There Is No UK Equivalent of a Pre-Import CE Approval Portal
Great Britain does not operate a general pre-import product compliance system requiring machinery importers to upload their Declaration of Conformity, test reports and technical file before every shipment.
Instead, customs declarations are submitted through CDS, the Customs Declaration Service, while OPSS and other authorities operate risk-based controls at the border.
OPSS works with HMRC to identify consignments considered at higher risk of being unsafe or non-compliant. A shipment can therefore clear customs without a product safety inspection, or it may be selected for documentary or physical checks.
This distinction is important:
CDS is a customs system. It is not a CE or UKCA certification portal.
2. Step One: Establish Who the UK Importer Is
Before the machinery is shipped, the parties should clearly establish who will act as the UK importer.
For imports into England, Scotland or Wales, the importing business will normally require a GB EORI number.
Most businesses appoint a customs agent, freight forwarder or customs broker to submit declarations on their behalf. However, appointing an agent does not remove the need for the importer to understand what goods are being declared and whether the information supplied is correct.
The commercial documents should consistently identify the parties involved, including the manufacturer, exporter, importer and consignee where applicable.
3. Step Two: Determine the Correct Commodity Code
The machinery must be classified using the UK Integrated Online Tariff.
The commodity code affects:
- – customs duty
- – import VAT treatment
- – licences or restrictions
- – customs declaration requirements
- – additional document codes that may be required
The exact commodity code should be determined from the machine’s design and function rather than simply copying the HS code provided by the Chinese supplier.
For example, a CNC machining centre, hydraulic press, portable electric tool and excavator will normally fall under different tariff classifications.
HMRC’s CDS guidance requires the declarant to use the tariff to identify the correct commodity code and any associated measures or document codes.
4. Step Three: Determine Which Product Regulations Apply
Customs classification and product compliance classification are not the same thing.
After identifying the machine, the importer should determine which UK product regulations apply.
For many industrial machines the main legislation is:
The Supply of Machinery (Safety) Regulations 2008.
These Regulations cover machinery, interchangeable equipment, safety components, lifting accessories, chains, ropes and webbing, removable mechanical transmission devices and partly completed machinery.
Depending on the equipment, additional legislation may also apply.
| Product | Typical considerations |
|---|---|
| CNC machine | Machinery Regulations, EMC, applicable machinery safety standards |
| Hydraulic or mechanical press | Machinery Regulations, potentially Schedule 2 Part 4 requirements |
| Portable powered hand tool | Machinery Regulations, EMC where applicable, relevant Type-C product standard |
| Excavator / loader / dumper | Machinery Regulations, Outdoor Noise Regulations, NRMM engine requirements |
| Generator | Machinery / electrical requirements, EMC and potentially Outdoor Noise Regulations |
| Wireless or radio-controlled machine | Machinery plus potentially Radio Equipment requirements |
| Machinery incorporating pressure equipment | Machinery plus potentially Pressure Equipment requirements |
Electrically powered machinery requires careful classification. Most machinery covered by the Machinery Regulations is excluded from the Electrical Equipment (Safety) Regulations as a complete machine, although the electrical safety objectives remain relevant through the Machinery Regulations’ electrical EHSRs. HSE specifically notes this distinction.
5. Step Four: Check Compliance Before the Machine Leaves original country
The best time to deal with product compliance is before shipment, not after the machine reaches a UK port.
For machinery, the responsible person must ensure that the applicable Essential Health and Safety Requirements are satisfied, a technical file is compiled, the appropriate conformity assessment procedure is completed, a Declaration of Conformity is produced and the correct conformity marking is applied. Appropriate safety information must also accompany the machinery.
A practical pre-shipment compliance file should therefore normally contain, where applicable:
- 1- Final product specification and model identification
- 2- Machine photographs and nameplate details
- 3- Applicable UK legislation
- 4- Applicable designated or recognised standards
- 5- Risk assessment
- 6- General arrangement and engineering drawings
- 7- Electrical and control schematics
- 8- Safety circuit information
- 9- Relevant test reports
- 10- EMC evidence where applicable
- 11- Noise emission and vibration emission declaration where applicable
- 12- Declaration of Conformity
- 13- English instructions and safety information
- 14- Third-party certificates where the conformity assessment route requires them
- 15- Evidence linking the reports and certificates to the exact machine being imported
This is the product compliance file.
It should not be confused with the documents normally submitted as part of the customs declaration.
6. Step Five: Submit the Customs Declaration Through CDS
The customs declaration is normally submitted electronically to HMRC through CDS-compatible customs software, usually by the importer’s customs agent.
The declaration includes information such as:
- – commodity code
- – customs procedure
- – importer and exporter
- – consignee and consignor
- – description and quantity of the goods
- – origin
- – customs value
- – transport information
- – certificates or licences where required
HMRC then processes the declaration and assigns the relevant customs status.
A typical shipment therefore follows this route:
Manufacturer → freight forwarder → UK port → CDS declaration → customs controls → clearance → delivery
But if the shipment is selected for product safety control, OPSS may become involved before release.
7. What Happens When OPSS Selects a Machine for Inspection?
OPSS operates product safety controls at the UK border together with HMRC and market surveillance authorities such as Trading Standards.
The system uses risk profiling rather than checking every machine entering the country.
When a consignment triggers an OPSS control, the routing code can indicate which authorities are involved. Current OPSS guidance identifies routes including:
| Route | Authority involved |
|---|---|
| 1S / 2S | OPSS / Trading Standards |
| 1U / 2U | OPSS / Trading Standards + National Clearance Hub |
| 1V / 2V | OPSS / Trading Standards + Border Force |
If an importer uses a customs broker, the broker will often see this routing information first.
Importers should therefore make sure their customs agent immediately forwards any CDS control messages, routing notifications or requests for documents.
8. Which Documents Are Uploaded When OPSS Stops the Shipment?
This is one of the most important distinctions for importers.
If the shipment has been selected for product safety checks and HMRC has suspended clearance, OPSS requires documents to be submitted through the CDS secure document upload system.
OPSS currently identifies the following minimum documents:
- – Import Declaration Report
- – Bill of Lading or Air Waybill
- – commercial invoice
- – packing list
This does not mean that the entire machinery technical file must automatically be uploaded for every import.
Further technical information may be requested if the authorities need to establish whether the machinery complies with applicable product safety legislation.
That could include documents such as the Declaration of Conformity, instructions, conformity assessment certificates, test evidence, photographs, product identification information or other relevant technical documentation.
9. How Does the Importer Know Why the Goods Are Being Held?
CDS provides messaging functionality for declarations under customs control.
HMRC states that a message can be sent to the trader’s Customs Declaration Service inbox where information or documents are required while the goods are subject to physical or documentary control.
If a customs agent submitted the declaration, communications may also be handled through the agent’s customs software.
The practical communication chain is therefore often:
HMRC/CDS → customs broker → importer
or, for product safety intervention:
HMRC/CDS → OPSS / Trading Standards → customs broker/importer
OPSS also publishes a dedicated border contact for consignments subject to product safety controls.
10. Where Are Documents Uploaded?
There is an important distinction between documents required for customs clearance and documents retained for product compliance.
CDS
CDS is used for the customs declaration and for supporting customs documentation where requested.
HMRC’s secure document upload service allows documents to be uploaded against the declaration’s Movement Reference Number (MRN).
HMRC currently accepts PDF, JPG, PNG and TXT files, with up to 10 documents in one upload and a maximum file size of 10 MB per document.
Technical File
The machinery technical file is normally maintained by the responsible economic operator rather than routinely uploaded to CDS.
It must instead be available when requested by an enforcement or market surveillance authority.
The technical file may contain test reports, design documents, risk assessments and other evidence demonstrating conformity.
Therefore:
Do not think of CDS as a storage location for the technical file.
11. CE or UKCA for Machinery Imported into Great Britain?
As of 2026, Great Britain continues to recognise CE marking indefinitely for machinery, alongside UKCA.
This means machinery being placed on the GB market may use either the appropriate CE route or UKCA route, provided the applicable requirements and conformity assessment procedures have been satisfied.
Where independent third-party conformity assessment is required, the conformity assessment body used depends on the marking route.
For example:
- – CE route: relevant EU Notified Body where third-party involvement is required.
- – UKCA route: UK Approved Body, subject to the available UKCA and Fast-Track arrangements.
Northern Ireland remains different and should not be treated as the same regulatory market as Great Britain.
12. Special Attention for Presses
Importers of presses should not assume that every machine follows the normal self-declaration route.
Certain presses are specifically included in Schedule 2 Part 4 of the Supply of Machinery (Safety) Regulations 2008.
One category includes:
presses and press-brakes for the cold working of metals with manual loading or unloading where the movable working parts may travel more than 6 mm and exceed 30 mm/s.
For machinery within Schedule 2 Part 4, the conformity assessment route must be checked carefully.
Current GB guidance allows self-declaration for Schedule 2 Part 4 machinery only where all relevant designated standards have been applied in full and those standards cover all applicable Essential Health and Safety Requirements. Otherwise an appropriate third-party conformity assessment route may be necessary.
Therefore the fact that a Chinese manufacturer supplies a document titled “CE Certificate” is not enough to establish that a press has followed the correct conformity assessment procedure.
13. Special Attention for Construction and Earth-Moving Machinery
Construction machinery can be subject to several overlapping requirements.
For example, excavators, dozers, loaders, dumpers, mobile cranes and certain other outdoor machines can fall within the Noise Emission in the Environment by Equipment for Use Outdoors Regulations 2001.
The Regulations cover 57 types of outdoor equipment.
Some are subject to both a permissible sound power limit and noise marking, while others are subject to noise marking only.
There was also an important change in April 2026, when updated noise measurement methods entered into force for equipment within scope. Importers and manufacturers dealing with new construction equipment should therefore check whether current noise documentation uses the applicable measurement procedure.
Construction machinery with combustion engines can also be subject to Non-Road Mobile Machinery (NRMM) engine emissions/type approval requirements.
Examples include bulldozers, excavators, construction machinery, forklifts and mobile cranes. VCA guidance requires engines for NRMM placed on the GB market to have the appropriate type approval and engine markings. The provisional GB approval arrangements for NRMM engines are currently able to continue through 31 December 2027 while the full GB scheme is developed.
14. What Changes If You Import the Machine Under Your Own Brand?
This is one of the biggest legal changes an importer can make to the supply chain.
A company is not necessarily just an importer because a factory in China physically manufactured the machine.
The guidance specifically states that where an importer places a product on the market under its own name or trademark, the importer assumes the responsibilities of the manufacturer.
Therefore, if:
XYZ Machinery Ltd in the UK orders a CNC machine from a Chinese OEM and sells it as “XYZ CNC-500” under the XYZ brand,
XYZ Machinery Ltd should not treat itself simply as a reseller of the Chinese manufacturer’s compliance documents.
It has effectively moved into the manufacturer role for conformity purposes.
15. What Must an Own-Brand Importer Do?
An own-brand importer should have sufficient technical control over the product to fulfil manufacturer obligations.
The UK brand owner should therefore obtain sufficient engineering information from the Chinese OEM before production or shipment.
Simply removing the Chinese manufacturer’s badge and attaching a UK brand plate does not transfer valid conformity evidence automatically.
The technical documentation must support the actual product being sold under the UK brand.
16. Importer Responsibilities Do Not End When Customs Clears the Machine
Customs clearance does not mean that OPSS, HMRC or another authority has “approved” the machine.
It simply means the consignment has been released through the border process.
Product compliance obligations continue after importation.
GB guidance requires economic operators, depending on their role and applicable legislation, to monitor compliance, cooperate with market surveillance authorities and take corrective action when they have reason to believe a product is non-compliant.
Corrective action can include bringing the product into conformity, withdrawing it from the market or recalling it.
For machinery intended for workplace use, the Health and Safety Executive is one of the principal enforcement authorities under the Machinery Regulations. Consumer machinery may instead be enforced by Trading Standards or the Secretary of State.

Final Thoughts
Importing machinery into Great Britain should be treated as two parallel processes:
Customs compliance determines whether the goods can pass through the UK border.
Product compliance determines whether the machinery can legally and safely be placed on the Great Britain market or put into service.
CDS manages the customs declaration. OPSS and other market surveillance authorities may intervene where a shipment is selected for product safety controls. There is no general requirement to upload a complete CE or UKCA technical file for every machinery import, but the relevant technical documentation must exist and be available where required.
For importers of CNC machines, powered tools, presses and construction machinery, the most important compliance work should therefore happen before the machinery leaves the manufacturer, particularly where the product will be sold under the importer’s own UK brand.
At ConformTest Ltd, we support machinery manufacturers, importers and private-label suppliers with machinery compliance assessment, CE and UKCA conformity, technical documentation review, risk assessment, electrical safety, EMC and noise compliance.
