- Perfluorohexane sulfonic acid (PFHxS), its salts and PFHxS-related compounds is listed in Annex A of the Stockholm Convention: to be eliminated worldwide.
- India has not yet ratified this listing (India adopts new listings one by one), but most treaty countries are phasing it out: buyers abroad may refuse it, and other Indian rules may still apply.
- On the EU REACH Candidate List of substances of very high concern (vpvb), since 07-Jul-2017. EU buyers must pass on safety information for articles containing more than 0.1%, and it may later need an authorisation.
- No EU REACH registration found: an EU importer (or your only representative) must register it before importing a tonne or more a year. Medicines and pesticide actives follow their own EU rules.
- Active on the US TSCA Inventory, so it can be imported into the US without a new-chemical notice.

- Basic customs duty 5% on every one of them; with social welfare surcharge and IGST 18% that makes about 24.49%.
- Lines that name a chemical are for that chemical; one that no line names goes under "Other" (2904 99 90).
