Data Sources

ChinaData.live combines public economic, trade, and market data from official and third-party sources with our own cleaning, structuring, metadata, charts, summaries, and quality checks.

Source Types

• Official statistical releases and ministry publications
• Customs, trade, and tariff classification sources
• International organization datasets and reference tables
• Public company, industry, and market research references where cited
• Source ledgers, retrieval notes, and metadata attached to custom deliveries

Construction Machinery Sales (CCMA)

The China Construction Machinery Association reports monthly sales by major manufacturers. Our construction machinery data directory separates total, domestic and export sales, official YoY changes, electric subsets and forklift scopes. Attributed public reprints supply this release; actual publishers, source URLs, checksums and missing periods are preserved in dataset metadata. These observations measure sales rather than production or customs exports.

Source Notes and Restrictions

Original source data remains subject to the license, terms of use, attribution requirements, and restrictions of the original data provider. Some pages may reference third-party estimates, market research, or commercial data providers for context, comparison, or citation only.

Where a dataset includes or is derived from third-party data with special restrictions, the applicable source notes will be shown on the dataset page, in the file metadata, or in the accompanying source ledger.

Need Source-Specific Context?

Custom deliveries can include source period, retrieval date, source URL, coverage notes, QA checks, and file checksums. For a scoped request, use the custom data desk.
