Us Chemical Import And Export Data: Dataset Structure and Field Coverage

The table below compresses the decision. Note the pattern in the last column: both US government sources carry public-domain terms, while the pan-global and European options impose conditions - contractual on OEC's side, attribution on Eurostat's.

Three caveats keep an analysis honest. First, HS codes classify products, not chemistry: chapter 39 lumps many plastics together at HS6 even where HS10 exists, so chapter-level totals mix resins, coatings and miscellaneous products unless you filter to specific headings like 2807 for sulphuric acid; oleum.

Second, general imports and consumption imports are different measures - GEN_VAL_MO versus CON_VAL_MO and CON_CIF_MO - and duty-adjusted CIF values will not match general-trade values, so label which measure a chart shows.

Third, monthly trade statistics answer a different question than regulatory volumes. If the claim concerns how much of a chemical was manufactured or imported into US commerce, the CDR's site-level volumes (reporting threshold 25,000 lb since 2006, published April 2026 for reporting years 2020-2023) are the citable source; the trade API tells you what crossed the border and what it was worth. Facility-level emissions questions belong to the EPA Toxics Release Inventory Basic Data Files instead - annual CSVs back to reporting year 1987 - and raw-material supply questions to USGS commodity chapters for soda ash, salt, sulfur, potash and phosphate rock.
