Sulfolane Price & Sourcing Guide: Market Trends, Cost Drivers & How to Buy in Bulk
Cost Drivers · Grades & Volumes · Producer Landscape · Buying Checklist
"What does sulfolane cost?" is a fair question with an unsatisfying short answer: it depends. There is no single price, because grade, volume, feedstocks, geography, and tariffs all push the number around - sometimes substantially. The good news is that the cost drivers are knowable, and once you understand them you can buy with confidence. 💰
This guide explains what really moves sulfolane prices, surveys the producer landscape, and walks through how to source reliably in bulk. New here? Start with the pillar guide What Is Sulfolane?
1. Why We Don't Quote a Single Price 📊
Online "sulfolane price per kg" numbers are often unreliable - they may quote tiny lab packs (which carry enormous handling premiums) or stale wholesale prices that don't reflect current feedstock costs or freight. An honest answer needs context: grade, volume, packaging, port, and timing all matter.
2. The Six Cost Drivers 🧭
Electronic / high-purity grade requires deeper purification, tighter QC, and stricter packaging - and it costs substantially more than technical grade. See grades & derivatives.
Drum, IBC, and isotank pricing differ markedly. Bulk (isotank) per-kg is typically the lowest, while small lab packs carry significant per-kg premiums.
Sulfolane is built from butadiene + SO₂. Both feedstocks have their own commodity dynamics (cracker margins for butadiene; sulfur economics for SO₂), and movements pass through to sulfolane cost. See how sulfolane is made.
Reaching electronic-grade purity requires extra vacuum distillation, polishing, and tighter QA - each step adds cost.
Sulfolane's solid-at-RT habit means heated containers are common for anhydrous bulk shipments. Freight and packaging often move the landed price more than people expect.
Recent US tariff shifts and tightening regulations on competing solvents (NMP, DMF) have added uncertainty to global trade flows for specialty solvents - sometimes in sulfolane's favor, sometimes against. Check current trade conditions when budgeting.
3. The Producer Landscape 🌍
The global sulfolane producer base is concentrated. Major players include:
Industry market studies consistently identify CPChem and Liaoyang Guanghua as the leading global producers - together accounting for a majority share of supply - with capacity additions in China shifting the regional balance further toward Asia.
4. Why China Is Central to Global Supply 🇨🇳
China is also the largest consumer of sulfolane - reflecting its huge refining base (for aromatic extraction) and rapidly growing semiconductor and battery industries (for high-purity uses). The Asia-Pacific region is the highest-growth zone for demand in current market forecasts.
For international buyers, this concentration has practical implications: competitive pricing on technical grade for bulk extraction use, and a deepening pool of high-purity capacity for electronic and battery applications. Sinolook Chemical sits in this ecosystem as an exporter, supplying customers in 50+ countries with both grades.

7. Frequently Asked Questions ❓
🔹 What is the price of sulfolane per kg?
There isn't one number. Price depends on grade, volume, packaging, freight, and current feedstock costs. Ask a supplier for a current, specific quote tied to your spec and packaging.
🔹 Is electronic-grade sulfolane much more expensive than technical grade?
Yes, materially so. The extra purification, tighter QC, and stricter packaging required for electronic grade carry real cost - but the use case (batteries, semiconductors) typically justifies it.
🔹 Who are the main sulfolane manufacturers?
Globally, Chevron Phillips Chemical and several major Chinese producers (notably Liaoning Guanghua, Liaoyang Liaodong, and The Sulfolane Company) dominate supply, with additional Japanese capacity.
🔹 Can I buy sulfolane in bulk from China?
Yes - China is the largest production base and a major exporter. Choose a supplier that can provide full COA, SDS, and traceable production data.
🔹 What about market growth?
Industry forecasts vary, but most point to steady mid-single-digit growth, driven by semiconductor cleaning, lithium-ion battery electrolytes, and continued refinery use - covered further in our global market trends article.
