When can a machinery movement qualify as not at risk?
Begin with the machine's real destination, not the address on the first delivery note. As of October 2026, a UKIMS not-at-risk movement must satisfy the test against onward movement to the European Union, including Ireland. Location in Northern Ireland alone is insufficient.
The authorisation belongs to a business. UKIMS requires UK establishment, compliance, financial standing and records retained for 5 years. A machine cannot make an ineligible movement eligible simply because a seller, carrier or buyer has seen a UKIMS number.
Document the intended use and any proposed onward destination. For a machine intended for the Republic, use the separate Northern Ireland-to-Republic guide. Ask your customs broker to confirm whether the destination test and the authorised business fit the actual movement.
Write an end-use note that follows the actual unit. Include the buyer, delivery point, intended work and any planned resale or onward movement. Give the same note to the authorisation holder, filer and broker. If the commercial plan changes before collection, stop and have the route checked again against the revised destination.
Who holds UKIMS and who files the IMMI?
Keep the holder, permitted user and filer as separate roles. Here is the October 2026 position. An authorised trader may permit a customs intermediary or haulier to use its UKIMS details for Internal Market Movement Information (IMMI). That permission does not prove the haulier holds the buyer's authorisation.
An IMMI can be submitted up to 30 days before arrival or after arrival. The full data set is due by the 10th of the following month. It requires the UKIMS number, and a customs intermediary submitting it must use software.
Those rules do not choose the filer for you. Name the authorised holder, obtain the permitted-use arrangement and assign the filing task in writing. Ask the Trader Support Service (TSS) or HMRC to confirm the representation and any signed-buyer-declaration arrangement.
Put the role split in one movement note. Name the UKIMS holder, the person giving permission, the intermediary or haulier using the details and the party submitting the IMMI. Add the machine identity, intended arrival and data deadline. Send the same note to everyone involved, then ask each party to confirm its own task before collection.
What if the machinery needs a full declaration?
Do not force a machine into the simplified route. As of October 2026, a movement without the UKIMS simplification needs a full declaration. The actual machine's exact 10-digit code and live tariff treatment must be established.
Origin is a separate evidence question. Support can use an exporter statement on origin or the importer's knowledge, subject to records. A used machine's build history is not proved by its brand alone.
Give the broker the full machine description, serial details, intended use and available origin records. Ask the broker to confirm the declaration, exact code, live rate, any eligible relief and whether the evidence supports a preferential claim.
Build the broker pack before asking for a release date. Match the machine description to the serial evidence, seller invoice and available origin records. Mark any missing information clearly instead of filling it by assumption. Ask the seller for the missing item, then give the updated pack to the broker and haulier together.
Arrange a pre-purchase inspection before relying on a listing's description. Discuss the farm machinery you need through our Northern Ireland agricultural sourcing page. For a digger or other plant purchase, see our Northern Ireland construction sourcing service.
What must work on the replacement TSS platform?
Test the live workflow before collection. As of October 2026, the replacement Trader Support Service platform applies to goods movements on or after 20 October 2026.
The launch date is settled, but a transaction still depends on live filing, UKIMS permission and haulier setup. Treat a successful plan on paper as unfinished until the parties can use the platform with the correct holder and movement details.
Run a live rehearsal before loading day. Use the exact holder, filer, haulier, machine and movement details. Ask each party to show that it can complete its own step on the platform. Record any missing permission or data, resolve it with TSS or the buyer's broker, and repeat the check before releasing the machine.
Do not leave the platform check to the loading day. Ask TSS and the buyer's customs broker to confirm that the intended filing and haulier arrangement works before the machine moves.
Pre-purchase checklist
Before you commit to machinery moving from Great Britain to Northern Ireland:
— Document the intended use and any proposed onward EU destination.
— Check that UKIMS authorisation has been granted to the correct business.
— Get the holder's permission and representation arrangement confirmed.
— Assign the IMMI filer and collect the full data set for its deadline.
— If a full declaration is needed, obtain the exact code and current tariff treatment.
— Test the live filing and haulier arrangement before the planned movement.
— Give the broker origin records before relying on a preferential claim.

Working with a buying agent who already does this
Euro Plant Finder works on the sourcing and export side. We identify the machine, check the seller, arrange inspection and coordinate serial, condition, origin and movement information.
The buyer's own customs broker decides whether UKIMS and IMMI fit, prepares any full declaration and handles local customs work. We keep the seller and haulier aligned with the evidence that the broker, TSS or HMRC requests.

Do I need a UKIMS number to move used machinery to Northern Ireland?
UKIMS may support an eligible not-at-risk movement, but it is not a number that automatically follows the machine. As of October 2026, UKIMS is a business authorisation with establishment, compliance, financial-standing and 5-year record requirements. The intended end use must also satisfy the test against onward movement to the European Union, including Ireland. If the simplification does not apply, a full declaration is needed. Give the planned movement to your customs broker before collection and ask which route applies.
Can the haulier use the buyer's UKIMS authorisation?
As of October 2026, an authorised trader may permit a customs intermediary or haulier to use its UKIMS details for an IMMI. That permission does not establish that the haulier holds the buyer's authorisation. The IMMI still requires the UKIMS number, and a customs intermediary submitting it must use software. Ask TSS or HMRC to confirm the holder, representation and any signed-buyer-declaration arrangement, then test that the haulier and filer can use the live platform before the machine moves.
When do I submit the IMMI for machinery?
As of October 2026, Internal Market Movement Information can be submitted up to 30 days before arrival or after arrival. The full data set is due by the 10th of the following month. The IMMI requires the UKIMS number, and a customs intermediary submitting it must use software. Those timings do not decide who should file for your transaction. Assign the filer, gather the complete machine and movement data, and have TSS or your customs broker check the planned submission before collection.
Can machinery declared not at risk be intended for the Republic of Ireland?
No. As of October 2026, a UKIMS not-at-risk movement must satisfy the test against onward movement to the European Union, including Ireland. Merely placing or storing the machine in Northern Ireland first is not enough to meet that destination test. Tell your customs broker the true final use and any proposed onward destination before buying. For a machine intended for the Republic, use the separate Northern Ireland-to-Republic route and do not present it as a Northern Ireland-only movement.
Can Euro Plant Finder handle Northern Ireland customs?
Euro Plant Finder gathers and coordinates seller and export-side evidence. We can identify the machine, check the seller, arrange inspection and keep serial, condition, origin and movement information together. The buyer's own customs broker decides whether UKIMS and IMMI fit, establishes any full declaration and submits or clears it where needed. TSS or HMRC confirms the authorisation and representation setup. We coordinate with those parties, but we do not hold the buyer's authorisation or act as the customs broker.
