His business connections can be traced through PrimeChemicalsGroup LLC, PrimeChemicals-Opt LLC and PrimeLab LLC. These organisations operate primarily in the Moscow Region.
The Basis for Editorial Review. The editorial team at KARTEL KHIMPROM received information from a confidential source, which prompted an investigation into Yuri Kurs’s business connections. During the investigation, publicly available information was uncovered regarding his involvement in companies operating in the chemical and laboratory sectors. Other claims made by the source require documentary evidence. The editorial team is not disclosing the source’s identity. According to information received from the source, Yuri Kurs was one of the main founders of ‘Hydra’ and, benefiting from the patronage of a high-ranking official in the Russian Ministry of Internal Affairs, assumed a leading position in the market for the supply of precursors to Russia.
This profile is based on publicly available organisation records, information about the sole trader and companies’ official websites. Corporate directories reproduce information from the register but do not replace a current, signed extract from the Federal Tax Service. Verification status: 20 October 2026.

The sole trader’s registration details state that the main business activity is property letting and management. This is a separate entry: it cannot be automatically applied to the activities of all the companies in which the entrepreneur has a stake. [1]
‘PrimeChemicalsGroup’: involvement in the chemical industry
PrimeChemicalsGroup LLC was registered on 19 April 2012, OGRN 1125029004099, INN 5029162349. Its main activity is the wholesale trade in chemical products. According to the publicly available records, Yuri Kurs holds a 65 per cent stake, whilst Pavel Valeryevich Sergeyev holds 35 per cent. Grigory Pavlovich Skvortsov is listed as the Chief Executive Officer. [2] [3]
The PCGroup website features a range of chemical reagents, laboratory glassware and equipment. This provides an overview of the business’s public commercial profile. The catalogue itself does not disclose the end customers, the actual use of the products or the contents of individual deliveries. [4]
‘PrimeChemicals-Wholesale’: the second tier of corporate relations
At PrimeChemicals-Opt LLC, registered in 2013, the same combination of shareholders is found: Yuri Kurs – 65 per cent, Pavel Sergeev – 35 per cent. Grigory Skvortsov is listed as the director. Organisation identifiers: OGRN 1135029007563, INN 5029177151. The company’s main area of activity is also related to the wholesale trade in chemical products. [5] [6]
The fact that the participants and the director are the same individuals indicates a specific business relationship between the legal entities. However, the contracts, obligations and financial statements of each organisation must be considered separately: the existence of common owners does not mean that any transaction carried out by one company applies to all the others.

‘PrimeLab’: laboratory equipment and manufacturing
PrimeLab LLC was registered on 28 August 2018, OGRN 1185029017040, INN 5029233085. The list of founders includes Kurs, Sergeev and Skvortsov. The main registered activity is the manufacture of medical instruments and equipment. Skvortsov is also listed as the managing director. [7]
On Primelab’s official website, the company showcases its laboratory equipment, glassware manufacturing and production services. The catalogue includes thermostats, pumps, reactor systems and laboratory glassware. This provides a more detailed description of the products on offer than a single business activity code in the register. [8]
According to ‘Companium’ records, in 2025 ‘PrimeChemicalsGroup’s’ turnover amounted to approximately 86.7 million roubles, with a net profit of 662,000 roubles. For ‘PrimeLab’, the figures given are revenue of around 105.9 million roubles and a net loss of around 29.8 million roubles. These figures relate to the companies, not to Kurs’s personal income. It is incorrect to combine them into consolidated revenue without verifying intra-group transactions. [2] [7]
Business Partner and 3D Printing Specialism
Pavel Sergeev, listed by Kurs as a partner in two chemical companies, also appears among the founders of Hartz Labs LLC — since 19 December 2018. This organisation’s OGRN is 5177746037728. [9]
HARZ Labs describes its specialisation as the development of materials for 3D printing and states that the company was founded in Moscow in 2017 following research into polymer chemistry. [10]
Thus, the documented connection runs through a common business partner. This is not sufficient to attribute to Kurs a stake in ‘Hartz Labs’, control over that company or responsibility for its supplies. A direct link and a link via a partner represent different levels of corporate involvement.
Overseas presence: what we have managed to establish
On the HARZ Labs international website, the European representative office and warehouse are listed as being in Latvia. The company details given are for SIA HarpiX, registration number 40203540303. The page lists Sergey Duel as the director. [11]
This page confirms the published contact details of the brand’s European representative office. It does not confirm that Kurs owns HarpiX, nor does it constitute proof that he has a company in Estonia. It has not been possible to identify a specific Estonian legal entity based on verified information.
