Do your goods meet the 35% rule?
Enter your costs and instantly see your regional value content — the share of your price added in the SADC region.
Indicative value-addition test only — not customs advice. Product-specific rules and the change-in-tariff-heading route may also apply, and SARS/Customs makes the final origin determination. Reviewed 2026-06-25.
How the calculation works
It applies the build-down formula: regional value content = (ex-works price − value of imported materials) ÷ ex-works price × 100. If the result is 35% or more, your goods generally meet the value-addition criterion for SADC origin. It is an indicative check — product-specific rules and the change-in-tariff-heading route may also apply, and customs makes the final determination.
RVC % = (Ex-works price − Imported materials) ÷ Ex-works price × 100

What is the ex-works price?
The ex-works price is the price of the finished goods at your factory gate — before freight, insurance, export costs and profit margins added downstream. It is the basis for the regional value content calculation.
