Export of car parts to the UK – Automotive post-Brexit [2026]

Poland is a hub for parts production (tier 1, tier 2) for British factories (Nissan, Toyota, Mini). In this sector, "time is money" is not a cliché – production line stoppages cost millions.

Rules of origin (Key)

Car parts have 0% duty only if they are "EU origin". In automotive, supply chains are global. An engine assembled in Poland may contain components from China, Japan, and the USA.

• You must calculate MaxNOM (Maximum value of non-originating materials). Usually for car parts, the non-EU input limit is 45% or 50% of the ex-works price.
• If you exceed this limit -> Your part is "Chinese" for the UK customs officer. Customs duty on parts is usually 4.5%.

Returnable packaging (Gitterboxes / KLT)

Parts are transported in reusable containers (Gitterbox, KLT).

• Do not declare them every time to customs as "final import/export" – you will pay VAT and create chaos.
• Use the procedure Temporary Admission (Temporary Admission) for packaging, or
• Consider them as means of transport (if they meet the definition), or
• Declare as return of packaging (Returned Goods).

Key: Record keeping. You must know how many gitter boxes left and how many returned.

Just-in-Time and AEO

For automotive suppliers, AEO status is almost essential to benefit from simplifications and avoid inspections that could delay delivery to the production line.

What the current official guidance means in practice

For operational work, the current procedural rules, declaration fields and relief conditions should be checked directly against the official guidance. For this topic, the core reference points are European Commission, GOV.UK / HMRC.

Operational watch-outs

Most delays come from inconsistent data between the commercial invoice, packing list, tariff classification, reference numbers and transport assumptions. Before shipment release, confirm who is responsible for clearance, whether the data set is complete and when the declaration must be filed.

Documents and data to prepare

The minimum working pack worth preparing before speaking to customs support or filing a declaration includes:

• commercial invoice with a complete goods description
• packing list with quantities, weight and package count
• HS/CN code and origin information
• EORI number and the party responsible for the declaration

Practical notes for UK-PL operators

For regular flows, keep a stable data template: goods description, HS code, origin, Incoterms, carrier details and source documents. This shortens response time and reduces border corrections.
