China's sulfur market has entered uncharted territory. As of early April 2026, domestic sulfur benchmark prices reached approximately 5,943 CNY/ton 

— a staggering 52% increase from roughly 3,910 CNY/ton at the start of March. 

Prices are at historical highs, spot availability is thin, and the supply-demand imbalance shows no immediate signs of easing.

For procurement teams and manufacturers who rely on sulfur as a feedstock, understanding the forces behind this rally is essential to making smart purchasing decisions in the months ahead.

A Perfect Storm on the Supply Side

The core driver of this price spike is a supply crunch, and it's hitting from multiple directions at once.

China imports over 60% of its sulfur, with the Middle East — particularly Iran and Qatar — serving as the primary source. In recent weeks, shipments from these key suppliers have stalled almost entirely. 

March port arrivals in China dropped roughly 50% year-on-year, and the import gap continues to widen with no clear timeline for recovery. 

At the same time, domestic supply isn't picking up the slack. Chinese refineries are in their spring maintenance cycle, which seasonally reduces output. 

International sulfur prices on foreign exchanges continue to climb as well, pushing up landed import costs. The result: both domestic and imported supply channels are tightening simultaneously, 

leaving the market with very little room to breathe.

Demand Isn't Slowing Down Either

On the demand side, the picture is equally tight. The phosphate fertilizer industry — one of the largest consumers of sulfur — is in peak spring application season, with operating rates holding at 75–80%. 

This creates steady, non-discretionary demand that doesn't ease off just because prices are high.

Beyond agriculture, industrial demand from the lithium iron phosphate (LFP) battery sector, sulfuric acid production, and broader chemical manufacturing remains stable. 

Downstream buyers are facing real margin pressure as input costs climb, but the nature of their demand is rigid — they need the material to keep production lines running, which is why orders keep coming in even at elevated prices.

Inventories Offer No Relief

Port-side sulfur inventories in China are currently sitting at five-year lows. The ongoing destocking trend means there's virtually no buffer to absorb supply shocks or cool off prices. 

When inventory is this low and replenishment channels are constrained, even small disruptions can have outsized effects on pricing.

What to Expect Going Forward

The short-term outlook (April–May) suggests prices could push toward the 6,200–6,500 CNY/ton range before any meaningful correction. 

A 10–15% pullback from peak levels would be a normal technical adjustment, but the underlying fundamentals — tight supply, strong demand, low inventory — remain firmly in place.

Over the medium term (3–6 months), the market is expected to stabilize at a higher plateau, likely oscillating between 5,000–5,500 CNY/ton. 

Import cost floors around 4,300 CNY/ton and the persistent global supply deficit (estimated at 5.13 million tons) should prevent any deep sell-off.

Looking further out, the structural picture for sulfur has changed. 

Driven by both traditional fertilizer demand and growing new-energy applications like solid-state batteries, the long-term price center appears to be shifting upward — 

from a historical range of 3,000–4,000 CNY/ton to something closer to 4,500–5,000 CNY/ton.

What This Means for Buyers

The key variables to watch are Middle East shipping activity, Chinese port arrival volumes, and inventory data. As long as the import supply gap remains unfilled, the price uptrend is unlikely to reverse.

For companies sourcing sulfur or sulfur-derived products, this is a market that rewards proactive procurement. Locking in supply with reliable partners, staying informed on logistics developments, 

and planning for sustained higher input costs are all practical steps worth considering right now.
