⚠️ Red Lane — the real cost
Duty rate is only part of the picture

The Red Lane rate may look similar or even slightly lower for some products. But duty is only one cost.

Customs declaration agent£150–£300Required for each Red Lane shipment
EU customs documentation£50–£100EUR1 certificates, T1 transit docs
Compliance checks£75–£150HMRC physical inspections
Storage / delay risk£50–£200+More frequent delays
Total additional cost£325–£750+Per shipment, on top of duty + VAT
Bottom line: Even if the Red Lane duty rate is marginally lower, the £325–£750+ compliance cost per shipment wipes it out many times over. For NI consumer e-commerce, Green Lane is almost always right.
