Three majors’ turnarounds pulled East China base oil utilization to 68.5%; imported HVI 150 spot at ¥8,240/t, a ¥365/t premium over domestic—widest in 3 months. Downstream demand recovers at the margin but don’t chase; lock forward prices now, spread compresses after Sept North China maintenance.

East China Group I base oil spot ¥4,280/t vs import parity ¥4,645—¥365/t spread, widest in 3 months, turnaround-driven. Utilization 71.3%; two North China hydrotreaters in Sept maintenance keep it tight. Lock forward prices now.

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%.

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.

Drawing on Jan–Jul 2026 seaborne data, we break down the four US Gulf Coast ethane terminals (Enterprise and Energy Transfer) that supplied ~99% of global seaborne ethane, and China's ~70% demand concentration (Satellite/Wanhua/Nangang), to analyze Asia's feedstock-lightening trend, VLEC freight and the risk/opportunity in long-term-contract structures.

Drawing on CNPC's Feb-2026 report, we unpack the capacity ramp behind China's ethylene equivalent self-sufficiency rising to 78.1% and 2026 total capacity approaching 70.75 Mt/y, and its repricing of polyolefin import dependence, regional spreads and trade flows.

Using H1-2026 ethylene-route margins, we dissect the structural divergence — persistent naphtha-cracker losses versus strong ethane/coal-route profitability — and its implications for Northeast Asian capacity.

We revisit the 2026 Hormuz disruption's impact on Asian naphtha and ethylene pricing, and reassess the real value of strategic reserves, feedstock diversification and resilience tooling.

Based on global capacity ramp-up and downstream demand recovery, we examine the marginal shift in lubricating grease/carbon black price equilibrium and regional spread opportunities.

We assess the downward pressure of new low-cost Middle-East fuel oil exports on Asia-Pacific prices and China's MTO demand absorption capacity.
