Mariusz joined Sloenka Logistic GR in May 2017 and has since closed exactly 4,832 customs declarations. In his work, facts and numbers matter, not empty promises. You won't find thick binders of theory with him. Instead, you'll get clear information on whether your transport will cross the border without penalties or if something needs fixing in the invoices. In 2024 alone, he caught documentation errors in 47 different carriers, protecting them from downtimes lasting an average of 3 days.

He specializes in Procedure 42, which allows your clients to avoid immediate VAT payment on imports. This is a specific cash saving. In the last quarter, Mariusz helped three companies from Szczecin optimize customs fees by a total of 284,320 PLN. He does this because he knows the regulations inside out and knows where the customs office looks for trouble. If documents reach his desk by 8:00 AM, they are usually checked and ready for shipment before 9:45 AM.

  • Average set verification time: 1h 22min
  • Number of audits conducted in 2024: 114
  • Effectiveness in appealing incorrect customs decisions: 96.4%

His approach is simple: no fluff. Mariusz doesn't like long meetings that bring nothing to business. If you call him with a terminal problem, you get step-by-step instructions on what to say to the customs officer. (Small note: Mariusz values punctuality, so if you arrange a call at 10:00, expect a connection exactly at 10:00). Facts and numbers count, and he sticks to them harder than port operating instructions.

Privately, he is a resident of Szczecin's Pomorzany district who spends every free Saturday tinkering with his old Volvo. He believes that in logistics, just like in an engine, every bolt must fit perfectly. Specifics instead of promises – that's his golden rule, thanks to which Sloenka Logistic GR clients sleep soundly while their cargo travels through Europe. If you need someone who isn't afraid of difficult questions from the Tax Office, Mariusz is the right man for the job.
