Dimethyl Disulfide Manufacturers in China: An Industrial Sourcing Guide
This guide introduces five companies with DMDS production information available through company disclosures or public reporting.
Published by NBWCHEM: We include our own manufacturing and supply information alongside other producers. This is a sourcing guide, not an independent ranking. NBWCHEM information is company-provided; other company profiles are based on the cited public sources.

Capacity figures refer to the disclosures described below. They should not be interpreted as verified current output or immediately available stock.
1. Gansu Nabowang Chemical Products Co., Ltd.—NBWCHEM
Manufacturing location: Baijianhu Salt and Nitrate Chemical Industrial Zone, Minqin County, Gansu Province, China
Website: NBWCHEM
Established in 2018, Gansu Nabowang Chemical Products Co., Ltd. operates its own manufacturing facilities and employs 110 people.
Our dedicated production lines have annual capacities of 10,000 metric tons of DMDS and 50,000 metric tons of sodium sulfide. We offer 99.5% DMDS for industrial customers.
Why Consider NBWCHEM?
NBWCHEM offers a defined starting point for industrial procurement: direct manufacturer contact, a one-metric-ton minimum order and several packaging options.
| Supply item | NBWCHEM offering |
|---|---|
| DMDS purity | 99.5% |
| Minimum order quantity | 1 metric ton |
| Packaging | Galvanized steel drums, IBC containers and ISO tanks |
| Availability | Stock available, subject to order confirmation |
| Dispatch | Generally 10–15 days after order confirmation, subject to packaging and transport schedules |
| Inspection | Third-party inspection before shipment available |
| Documentation | Export customs declarations and Certificates of Origin |
| Shelf life | One year under the specified storage conditions |
Depending on the shipment, exports can be arranged through Tianjin, Qingdao or Shanghai ports, or an appropriate land route.
Factory, production-line and equipment photographs are available for supplier evaluation. Selected loading photographs and redacted export records can also support a review of our shipment experience.
Production information and export evidence serve different purposes: manufacturing materials support an assessment of the factory, while customs records document specific shipments.
2. Guizhou Xingfa Chemical Co., Ltd.
Production location: Guizhou, China
Official information: Xingfa DMDS commissioning announcement
Xingfa Group’s official announcement describes the successful commissioning of Guizhou Xingfa’s DMDS installation and the production of material with a reported concentration of 99.8%.
The disclosed project includes a designed DMDS production capacity of 10,000 tonnes per year, together with related sulfur chemical products.
Why Consider Xingfa?
The company provides concrete production information covering the installation, commissioning process and resulting product. This makes it a useful candidate for buyers seeking evidence of manufacturing capability.
Buyers should request the current commercial specification, supplying legal entity and delivery availability. The reported commissioning concentration should not automatically be treated as the guaranteed specification for every order.
3. Xinjiang Guanghui Luyou Sulfur Chemical Co., Ltd.
Production location: Yiwu County, Hami, Xinjiang, China
Public production information: Yiwu County Government report
A 2022 government report states that the company’s first-phase 10,000-tonne-per-year DMDS project had reached its production targets. The report also records its role in developing the industrial DMDS group standard T/CIESC 0043—2022 and historical export activity.
Why Consider Guanghui Luyou?
Its production background is supported by public reporting beyond a supplier catalogue. The disclosed customer applications include petroleum refining and methanesulfonic acid manufacturing.
The larger 40,000-tonne-per-year DMDS figure in project materials refers to a phased development plan. Buyers should confirm current operating capacity rather than assume the entire planned capacity is available.
4. Langfang Hawk T&D
Company website: Langfang Hawk T&D
Hawk’s official website lists a dedicated Dimethyl Disulfide Series among its manufactured products. It also describes a research and development centre and two production bases.
Why Consider Hawk?
The company’s presentation places DMDS within an established chemical production and development business, making it a candidate for technical and commercial inquiries.
Its homepage displays an annual capacity figure of 22,000 tonnes, but the reviewed information does not clearly assign that figure specifically to DMDS. Buyers should confirm the relevant manufacturing entity, factory location, product grade and DMDS capacity directly.
5. NHU
Official product page: NHU DMDS
NHU Performance Materials’ official website explicitly describes DMDS produced by NHU. Listed applications include sulfur supply for refinery catalyst activation and use as a raw material for methanesulfonic acid.
Why Consider NHU?
The official production statement and industrial product positioning make NHU another manufacturer worth evaluating.
The reviewed product page does not specify DMDS production capacity, manufacturing location or a guaranteed purity. Buyers should request those details together with the appropriate sales contact and supplying entity.
How to Compare DMDS Manufacturers
A manufacturer shortlist is the beginning of supplier qualification. The next step is to compare each offered product against the same purchasing requirements.
| Evaluation area | Information to request |
|---|---|
| Manufacturing identity | Legal producer name, factory address and relationship to the seller |
| Product quality | DMDS assay, impurity limits and test methods |
| Batch documentation | Recent representative COA and current SDS |
| Production capability | Product-specific capacity and available order volume |
| Packaging | Container specification, net weight and transfer connections |
| Delivery | Dispatch schedule, shipping route and agreed trade terms |
| Inspection | Sample testing or third-party inspection arrangements |
| Shipment experience | Relevant, appropriately redacted export and loading records |
A company may manufacture some products and distribute others. Confirming the actual source of the quoted DMDS helps buyers understand responsibility for quality, traceability and delivery.
Match the Product to the Application
DMDS purchasing requirements vary by end use.
For refinery catalyst activation, the material should meet the catalyst supplier’s approved specification. For steam cracking or dehydrogenation applications, the plant’s technical requirements determine acceptance. Organic synthesis customers may need to assess specific impurities and reaction performance.
An overall assay such as 99.5% or 99.8% is only one part of that evaluation.
