HS classification revisions
HS classification revisions is revision selector (H0 through H6) on Comtrade queries that pins which Harmonized System nomenclature vintage a series is coded against, recorded per row in fields like classificationCode and isOriginalClassification. In Datadory's catalog of 1,744 datasets, UN Comtrade Plus TradeFlow long_description and UN Comtrade Plus TradeFlow fields are working examples.
What is HS classification revisions?
The revision selector (H0 through H6) on Comtrade queries that pins which Harmonized System nomenclature vintage a series is coded against, recorded per row in fields like classificationCode and isOriginalClassification.
In this catalog it appears concretely: - UN Comtrade Plus TradeFlow long_description — "The TradeFlow interface lets users build queries across ... commodity classification (HS, with H0/H1/H2/H3/H4/H6 revisions available), trade flow (import, export, re-import, re-export), frequency (annual or monthly)". - UN Comtrade Plus TradeFlow fields — "classificationCode', 'classificationSearchCode', 'isOriginalClassification". - UN Comtrade Plus TradeFlow coverage temporal field — "Verified live responses returned 2022 and 2023 periods under HS H6".
Why does HS classification revisions matter when choosing a dataset?
A table is only as good as the column you actually need. If this field is absent, sparsely populated or defined inconsistently across rows, no amount of surrounding richness rescues the analysis, so it deserves its own line in your evaluation checklist.
The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and UN Comtrade Plus TradeFlow long_description lets you inspect the real artifact before any budget is committed.
How do you evaluate HS classification revisions in a data source?
Treat every claim of this attribute as testable:
- Open UN Comtrade Plus TradeFlow long_description and confirm its record — "The TradeFlow interface lets users build queries across ... commodity classification (HS, with H0/H1/H2/H3/H4/H6 revisions available), trade flow (import, export, re-import, re-export), frequency (annual or monthly)" — against the files you actually receive.
- Open UN Comtrade Plus TradeFlow fields and confirm its record — "classificationCode', 'classificationSearchCode', 'isOriginalClassification" — against the files you actually receive.
- Open UN Comtrade Plus TradeFlow coverage temporal field and confirm its record — "Verified live responses returned 2022 and 2023 periods under HS H6" — against the files you actually receive.

Frequently asked questions
What is an example of HS classification revisions?
UN Comtrade Plus TradeFlow long_description is the clearest example in this catalog. Its record states: "The TradeFlow interface lets users build queries across ... commodity classification (HS, with H0/H1/H2/H3/H4/H6 revisions available), trade flow (import, export, re-import, re-export), frequency (annual or monthly)".
Is data described as "HS classification revisions" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides HS classification revisions?
Open UN Comtrade Plus TradeFlow long_description next to UN Comtrade Plus TradeFlow fields and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
