Does potassium hydroxide (caustic potash) qualify for India–UAE CEPA?

Yes, if it meets the Annex 3B Product-Specific Rule "CTSH + VA 40% (CEPA Annex 3B Product-Specific Rule; tariff-shift AND value addition both required).": it must BOTH change tariff classification (CTSH) AND add at least 40% regional value content — both conditions are required, not either/or.

What proof is needed at import?

A preferential Certificate of Origin filed through eCoO 2.0, presented at customs before clearance. Without it, the 7.5% MFN duty applies.

Qualifying under the Rules of Origin

To claim the CEPA preference on potassium hydroxide (caustic potash) (HS 28152000), the goods must qualify as UAE-originating: the Product-Specific Rule (Annex 3B) is "CTSH + VA 40% (CEPA Annex 3B Product-Specific Rule; tariff-shift AND value addition both required).": the goods must undergo a change of tariff sub-heading (CTSH) AND add at least 40% regional value content — both conditions, not either/or. Caustic potash is used in soaps, fertilisers, potassium chemicals, food processing and battery electrolytes, with steady Indian industrial demand. CEPA removes the 7.5% basic duty. UAE chlor-alkali production satisfies the 40% regional-value-content rule where the material is genuinely made locally rather than repackaged. KOH is strongly corrosive, bringing hazardous-cargo classification, lined-tank or drum requirements and handling approvals that gate the shipment independently of duty. Food-grade applications add purity documentation. Keep the certificate of analysis with the origin declaration. A valid Certificate of Origin filed through the eCoO 2.0 system must accompany the shipment; without it, customs charges the 7.5% MFN rate instead of the preference.
