 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# TANTECH HOLDINGS LTD (NASDAQ: TANH) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is TANTECH HOLDINGS LTD, listed on NASDAQ under ticker TANH. The ISIN and LEI are not on the record. The security type is Non-operating entity type (other), the sector is 2860 Industrial Organic Chemicals, and the jurisdiction is Virgin Islands, British. The segment is not on the record. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 30 filings in the twelve months to 2026-11-08, across 25 filing days. The filings comprise 16 results, 6 regulatory filings, 5 directors' dealings and 3 prospectuses. The median gap between filing days is 6.5 days, against a NASDAQ median of 6.0 days and a sector median of 7.0 days. The latest filing is dated 2026-10-02 and is of type results, 37 days before the record date. The NASDAQ median latency is 5.0 days and the sector median latency is 4.0 days.\n\n## Auditor\n\nThe auditor of record is not on the record, because the latest annual report cover carries no auditor name tag, and the auditor's location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, and the segment move is not on the record. The halt flag shows the issuer as listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable because the chapter's orderability section names no client categories, so the outcome cannot name its client category. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page as read, and the count is zero.\n\n## Open research\n\nNo openly published research notes were found on the record, and the count is zero.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe vintage is sealed. Sealed years that hold the issuer are 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04, and the live record began on 2026-09-12.\n\n## Sources\n\n6 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.sec.gov/files/company_tickers_exchange.json (identity.exchange)\n- https://data.sec.gov/submissions/CIK0001588084.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/TANH (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/TANH (the record)\n",
