China Disclosures

Offline validator and decoder for China's 18-character Unified Social Credit Code (统一社会信用代码, GB 32100-2015) -- the single identifier every registered Chinese organization (company, social organization, government institution) carries. Checks the format (length, allowed 31-character set, and the GB 32100-2015 check-digit algorithm) and, when valid, decodes the registration authority (e.g. Market Regulation for an ordinary company), the entity type, and the province from the 6-digit administrative-division segment. No network call -- this is a pure offline algorithm plus small public lookup tables (GB/T 2260 province codes), so it works for any syntactically plausible code, including ones that do not exist. Answers "is this a valid Chinese company code", "decode this unified social credit code", "check digit for 9111000012345678AU", "which province does this USCC belong to". IMPORTANT: this validates FORMAT ONLY -- a format-valid code is not proof a real company holds it; confirming existence requires a live registry lookup this tool does not perform (see format_only_note in every response).

Full-text search over CNINFO (cninfo.com.cn), the official disclosure feed for BOTH Chinese A-share exchanges — Shenzhen (SZSE) and Shanghai (SSE), STAR Market (科创板) included. Covers A-share-listed companies with zero HK or US nexus — the deals and IPOs invisible to every SEC- or HKEX-based tool in this catalog (a China-to-China licensing deal, or a STAR Market IPO prospectus). Answers "A股许可协议公告" (A-share licensing announcements), "STAR Market IPO prospectus filings", "科创板 招股说明书". Search terms must be Chinese (e.g. "许可" for licensing/approval disclosures, "招股说明书" for IPO prospectuses) — do not translate an English query and search that. Optionally filter to one verified board segment (`board`). Returns company, stock code, title, date and PDF link, plus the true total match count.

Hong Kong IPO / listing financing filings — the Global Offering prospectus and formal notice every company files with HKEX when it goes public or completes a placement. Answers "recent HK IPOs", "HKEX biotech IPO financing", "which companies just listed on the Hong Kong Stock Exchange", "STAR/HK biotech listing documents". Sourced from HKEXnews disclosure filings titled "GLOBAL OFFERING" — covers every industry, not biotech-specific, so filter with `query` (a company name) to find a particular listing. Returns the company, stock code, document category (Listing Documents = the prospectus PDF, or Announcements and Notices = the formal notice for the same event), filing date and PDF link. HKEX Main Board / GEM only — an A-share STAR Market (科创板) IPO is a different exchange, see cninfo_disclosure_search.

Biotech/pharma licensing and collaboration deals disclosed by Hong Kong Exchange (HKEX)-listed companies — covers deals with NO US-listed party at all (e.g. a Chinese HKEX-listed biotech out-licensing a drug to an Indian, Japanese or European partner), which SEC-filing-based tools (china_licensing_deals, pharma_licensing_deals) structurally cannot see. Answers "China-to-Japan biotech licensing deals", "recent Asia pharma out-licensing deals not filed with the SEC", "HKEX biotech collaboration agreements". Sourced from HKEXnews disclosure filings whose title contains "License Agreement" or "Licensing Agreement". Returns the company, stock code, headline, filing category and date, and the filing PDF. Coverage requires the Chinese/Asian party to be HKEX-listed — a private-to-private deal with no HK, US or A-share party is invisible to every tool in this catalog.
