For a record lookup, start with the China company registry guide. For datasets and methods, see the research index.

These articles explain what registry fields mean. These are the measurements they draw on when a number is quoted, so you can see what sits behind the number instead of taking it on faith.

Some guides reuse the same samples

Several guides ask different questions about the same manufacturers. Reusing a sample does not provide independent confirmation. When you cite a result, include its source, observation date and sample limits. Find the datasets and methods in the research index.
