The 10 Best Specialty Chemicals Datasets in 2026

10 Specialty chemicals picks, ranked on what's inside: field richness, coverage depth, fit for the job. EPA TSCA Chemical Substance Inventory leads — Entries claimed confidential render as accession-number placeholders, so screening queries return honest gaps instead of silent omissions.

Every dataset here carries a 0–10 score built on documented fields, and the ranking follows those scores. When records tie, coverage breaks it: more geography, deeper history, finer granularity. Cadence isn't a scoring axis — it's a delivery setting. Delivered daily, weekly, or hourly, your call.

    InChIKey-Deduplicated ClassyFire/ChemOnt Label Collection

    Why it ranks eighth: sheer scale - nothing else in the catalog approaches seventy-three million labelled compounds - and the ready-made splits mean a classification model starts against a defensible baseline rather than a homemade one.

Frequently asked questions

What is the single best specialty chemicals dataset?

On our scoring, ECHA CHEM at quality 9/10 - one record per substance across well over 100,000 EEA registrations, with REACH dossier sub-records, harmonised and industry C&L classifications and regulatory obligations in a single field dictionary. If your question is US commerce status rather than European obligations, the EPA TSCA Chemical Substance Inventory is the record that answers it.

How many substances are on the EPA TSCA Inventory?

The July 2026 snapshot carries about 70,800 non-confidential listings, split 36,522 active against 34,252 inactive, alongside roughly 16,000 confidential-entry records that render as accession-number placeholders. Each row states commercial activity status as an explicit field, so screening queries distinguish a confirmed inactive substance from an unlisted one.

Which dataset has UK chemical production statistics at product level?

The ONS PRODCOM Final Results on data.gov.uk. Sales value and volume cover 25 divisions including Division 20 chemicals, resolved to thousands of eight-digit product codes with 2025 estimates, revised 2024 figures and finals back through 2015-2023, while Table 1 reaches to 2006. It carries National Statistics designation.

Which dataset should I use to size a local US chemical market?

The US Economic Census for NAICS 325. The 2022 edition documents 14,961 establishments and $901.0 billion in value of shipments, broken out as geography crossed with six-digit chemical industries down to county level, with comparable vintages every five years. Pair it with TSCA when the sizing needs to connect dollars to specific substances.
