Does calcium oxalate 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 calcium oxalate (HS 29171120), 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. Calcium oxalate is a specialty salt used in ceramics, analytical reagents and as a processing intermediate. The 7.5% MFN duty falls to zero under CEPA. As a low-volume specialty, most regional supply is traded rather than manufactured in the UAE, so the 40% regional-value-content rule frequently fails — the error to avoid is assuming a Dubai invoice means UAE origin. Ask the supplier to identify the manufacturing site in writing. Where the material genuinely qualifies, the full duty removal is worth the documentation effort on a recurring reagent line. 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.
