Gebrüder Weiss has taken a majority stake in Istanbul-based customs warehousing company Sienzi Lojistik.

The company will operate independently under the name Sienzi Lojistik – a Company of Gebrüder Weiss.

The deal is expected to close in January 2026, pending regulatory approval. Murat Doğan will stay on as managing director and retain his ownership stake.

"This investment strengthens our foothold in the Turkish market and brings our partner's customs warehousing expertise into the Gebrüder Weiss network on a long-term basis," said Wolfram Senger-Weiss, CEO of Gebrüder Weiss.

"It's a strategic step to deliver integrated, one-stop logistics solutions for customers with demanding supply chain requirements."

Murat Doğan, who also serves as vice president of the Turkish Customs Warehouse Association, said joining forces with Gebrüder Weiss, one of the industry’s most traditional logistics companies, enhances its competitive edge.

"This partnership allows us to broaden our service portfolio and promote Türkiye’s role in international trade," Doğan said.

Gebrüder Weiss and Sienzi Lojistik have been working together in Türkiye for nearly a decade. The company's bonded warehouse plays a key role in handling imports, exports, and transshipment operations.

"We can store goods until customs duties are cleared or transit procedures are completed and consolidate shipments from various countries of origin. This solution offers greater flexibility, cost efficiency, and planning reliability for companies with complex logistics needs," said Mişel Yakop, country manager Türkiye at Gebrüder Weiss.

With this acquisition, Gebrüder Weiss is strengthening its Istanbul hub as a full-service logistics center and exploring new business segments, including textiles and industrial clients.

"Istanbul's location—at the crossroads of Europe and Asia—makes it a strategic gateway to numerous markets. We see significant growth opportunities in this region," said Thomas Moser, director and regional manager Black Sea/CIS at Gebrüder Weiss.

Sienzi Lojistik, founded in 2007, specializes in customs and warehouse logistics. The company has 42 employees and operates a bonded warehouse with a permanent license near Muratbey Customs Office—one of Türkiye's largest customs hubs.

Its logistics site includes 6,000 square meters of enclosed bonded warehouse space, 1,000 square meters of open bonded storage, a high-bay warehouse with capacity for 5,000 pallets, 6,000 square meters of enclosed logistics space, 15,000 square meters of open storage space, and 1,000 square meters of office space.
