Rule of Origin (CEPA Annex 3B, primary source): CTSH + VA 40% (CEPA Annex 3B Product-Specific Rule; tariff-shift AND value addition both required).
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. Read that rule for what it is: Annex 3B supplies it at chapter level, so it governs hundreds of eight-digit codes rather than this one. It is the correct rule to apply, and it is also the place to check for a more specific carve-out before committing to a claim. Calcium oxalate is a specialty salt used in ceramics, analytical reagents and as a processing intermediate. The basic 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, which on a reagent line moving in kilogram quantities through distributors is the default rather than the exception. 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, and the declaration can be reused across shipments once established. Where it does not, declining to claim is the correct and cheaper answer — a reversed claim on a consumed reagent is an expensive way to learn the supplier's role. 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.
Check your own figures in the Rules of Origin (RVC) qualifier. Qualifying is only half of it — the preference is claimed with a Certificate of Origin, issued in the UAE before shipment or retrospectively within 12 months.
Frequently asked questions
- 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 is the Rule of Origin for calcium oxalate?
- Per CEPA Annex 3B: CTSH + VA 40% (CEPA Annex 3B Product-Specific Rule; tariff-shift AND value addition both required).. RVC% = [(FOB − value of non-originating materials) / FOB] × 100 (FOB basis).
- 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.
