Eliminate costly delays, quality disputes, and over‑priced shipping. Corporate Purchasing Managers, Technical Directors, and Operations Leaders who need consistent, high‑purity 1,6‑Hexanediol for polymers, coatings, and pharmaceutical intermediates can now secure supply within 48 hours from a certified GMP factory.
1. Sky‑rocketing Prices. Many distributors add a 30‑45 % markup to compensate for fragmented supply chains, eroding your product margin.
2. Inconsistent Purity. Batch‑to‑batch variation (≥ 98 % vs. 95 %) leads to failed QC, re‑work, and delayed product launches.
3. Slow Delivery & Expensive Freight. Traditional Asian freight routes can add 3‑4 weeks to lead time, while air freight inflates cost by 60 %.
4. Limited Customization. OEM/ODM requests for specific moisture content or solvent‑free grades are often rejected, forcing you to source from multiple vendors.
5. Regulatory Uncertainty. Missing certificates (CE, FDA, ISO 9001) expose you to compliance risks in the U.S. and EU markets.

Polyester Resin Manufacturing. A U.S. polymer plant replaced a 30 % higher‑priced Chinese supplier with our 1,6‑Hexanediol, achieving a 12 % reduction in cycle time and 37 % cost saving on raw material spend.
Pharmaceutical Intermediate Production. A mid‑size API manufacturer required USP‑grade 1,6‑Hexanediol for a new active ingredient. Our OEM service delivered a custom‑dry‑grade (≤ 0.02 % water) within 2 weeks, enabling a **launch ahead of schedule**.
Coating & Adhesive Formulations. A European coating company needed a solvent‑free grade for low‑VOC compliance. Our REACH‑certified batch passed their internal audit on the first trial, eliminating the need for costly re‑testing.
The standard MOQ is **25 kg** (IBC). For larger projects we can accommodate **1 ton** or **5 ton** bulk bags with volume discounts.

Yes. Every batch is shipped with a **GMP‑validated CoA**, including HPLC purity, water content, and heavy‑metal limits, all signed by our senior chemist.
Absolutely. Our pilot line can adjust moisture to **≤ 0.01 %**, and we can mill the product to **≤ 200 µm** for specific formulation needs.
We offer **FOB Zhengzhou**, **CIF Los Angeles**, and **DDP New York**. Express air freight is available for urgent orders, typically **5‑7 days** door‑to‑door.
Our dedicated Technical Service Team (24 h response) provides formulation assistance, safety data sheets, and troubleshooting. Contact us via email or WhatsApp +86 19943830844.
