Domestic Group III base-oil operating rate rises to 71%, with key viscosity-index and oxidation-stability bench tests on par with imports; paired with on-chain carbon labels, local Group III earns a 1%–2% premium in re-export pricing, cutting reliance on Middle East and Korean imports.

Fully-refined paraffin food-grade share rises to 42%; microcrystalline wax gains in rubber protection and cosmetic carriers; exports +12% yoy with high-melt and food-grade specs driving the increment. Base-oil Group II/III domestic share reaches 47%, import premium narrows and localization accelerates. Traders should fold wax/base-oil combinations into the re-export category matrix to meet ESG carbon-label demand.

Domestic Group II/III base-oil capacity is ramping, lowering import dependence; spreads and certification drive substitution speed. SNSUC lists base oil, white oil and liquid paraffin together for downstream lubrication buyers.
