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.

EU CBAM and downstream carbon-disclosure rules force cradle-to-gate accounting across petchem re-exports. SNSUC models full-lifecycle carbon for base oil/lubricants; paraffin (rising food-grade share) and butadiene rubber win green-premium orders via low-carbon routes, with digital warrants carrying carbon labels—feeding the platform's ESG tracking module.

As one of SNSUC's 13 categories, paraffin & microcrystalline wax upgrade toward food-grade packaging, pharma and rubber-protective grades; fully-refined paraffin exports +12% yoy, food-grade 38%, microcrystalline substitution 65%.
