Who owns Ningbo ZRCC LyondellBasell New Material Company Limited
One company in the researched set discloses a stake in Ningbo ZRCC LyondellBasell New Material Company Limited, none of it sized by anyone who discloses it. Ningbo ZRCC LyondellBasell New Material Company Limited is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Ningbo ZRCC LyondellBasell New Material Company is an equally held venture of LyondellBasell and Sinopec that runs a second propylene oxide and styrene monomer unit at Zhenhai in Ningbo, China, next to the pair's earlier plant on the same site. It was announced in December 2019 and finalised in January 2021, uses LyondellBasell's PO/SM process technology while Sinopec contributes the refinery integration and feedstock at Zhenhai, and is designed for about 275,000 tonnes a year of propylene oxide and 600,000 tonnes a year of styrene monomer. The two partners market the output separately in equal shares, selling propylene oxide into polyurethane foams and styrene into plastics and rubber in the Chinese market.

Ningbo ZRCC LyondellBasell New Material Company Limited files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from LyondellBasell and Sinopec finalize joint venture to manufacture propylene oxide and styrene monomer in China (LyondellBasell), LyondellBasell and Sinopec announce joint venture to manufacture propylene oxide and styrene monomer in China (PR Newswire, December 2019) and LyondellBasell locations: Ningbo, China. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- LyondellBasell Industries N.V.. Exhibit 21.1 to the FY2025 10-K (filed 20 Feb 2026) states that Lyondell China Holdings Limited owns a 50% interest in Ningbo ZRCC LyondellBasell New Material Company Limited. This is a 50 percent ownership interest, written here as the number 50, not as a fraction of 100. LyondellBasell's balance sheet carries a single combined 'Equity investments' line ($3,963 million at 31 Dec 2025 per the 10-K; $3,875 million at 30 Jun 2026 per the most recent 10-Q) covering all equity-method investees together, so no individual carrying value is disclosed for this venture: value_usd is null. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Ningbo ZRCC LyondellBasell New Material Company Limited where a holder stated one, and are missing where no holder did.
