Knowledge base

Guides

Practical guides on transport to the UK, customs clearance, exhibition logistics and warehousing.

We write about what actually holds a load at the border: documents, customs, returns and warehousing. No filler, just usable detail.

What is in the OTSL knowledge base?

The OTSL knowledge base is practical articles on international road freight: customs clearance and border procedures (SIVEP, GMR, PBN, ATA carnet), transport to the United Kingdom, Ireland and Switzerland, trade fair logistics, warehousing and returns. We cover the real risks and how to prevent them before they hit your cargo.
