WTConsulting GmbH

What WTConsulting GmbH does

WTConsulting GmbH is a privately held, founder-owned regulatory affairs and scientific consulting firm headquartered in Liestal, Switzerland, near Basel. Founded in 2007 by Uli Wietschorke, the firm specializes in two core areas: global chemicals registration under EU REACH and equivalent regimes in the USA, Canada, Japan, China, Korea, and Australia; and regulatory compliance for food contact materials and substances (plastics, paper and board, coatings, multi-layer materials, rubber, elastomers, silicones, and printing inks). The company has issued over 1,700 food contact compliance certificates and submitted 500+ successful petitions to EFSA, national authorities, and the US FDA. Service extensions cover cosmetics ingredient safety, toy safety, medical device biocompatibility, pharmaceutical packaging, food additives, and feed additives, addressing regulatory pain points for chemical manufacturers and consumer product companies operating across multiple jurisdictions.

The firm operates as a six-person boutique consultancy with deep technical bench strength: an ERT-certified toxicologist (Dr. Claudius Grossmann), two ecotoxicologists (Dr. Yuanfang Zheng and Dr. Johannes Völker), a biologist specialized in food safety and printing inks (Thomas Bächler), and business administration support (Delia Bächler). Underlying technical capabilities include IUCLID dossier compilation for REACH submissions, QSAR modelling for hazard prediction, NIAS (Non-Intentionally Added Substances) assessments with analytical screening, migration calculation and modelling for food contact materials, and read-across plus weight-of-evidence toxicological methods spanning in vitro, in vivo, and in silico approaches. The firm is GDPR-compliant and positions itself as an independent, neutral Swiss consultancy.

Commercially, WTConsulting generates revenue through project-based professional services engagements, with tiered support models (Basic, Professional, Premium) for ongoing REACH compliance and customized pricing for food contact substance approvals and safety assessments. Pricing is not publicly disclosed; engagement begins with a non-binding consultation. Go-to-market is sales-led and direct, relying on the firm's website, demonstrated regulatory expertise, and the personal reputation of its expert team to attract clients. Distribution is direct to enterprise clients in the chemical and consumer products industries globally, with no resellers, channel partners, or programmatic API access. Marketing channels are limited to the company website, contact forms, and the founders' industry networks.
