Asymchem locations span Tianjin, Dunhua, Fuxin, Shanghai, and the UK, plus US offices. Here's where the CDMO operates and what each site does.
Asymchem's locations are concentrated in China, with primary manufacturing sites in Tianjin, Dunhua, and Fuxin, a development center in Shanghai, plus a UK research presence and US-based business operations. The company is a contract development and manufacturing organization (CDMO) that produces small-molecule APIs, intermediates, and finished drug products for pharmaceutical and biotech clients worldwide.
If you are mapping the company's global footprint for supplier due diligence, a site audit, or an investment thesis, the practical answer is that Asymchem's capacity sits mostly in northern and eastern China, with a smaller international layer layered on top.
Where Is Asymchem Headquartered?
Asymchem is headquartered in Tianjin, China, where its largest manufacturing campus sits inside the Tianjin Economic-Technological Development Area (TEDA). The listed entity, Asymchem Laboratories (Tianjin) Co., Ltd., is registered there as well.
That location is not incidental. Tianjin is one of northern China's biggest port cities, which shortens export timelines for API shipments headed to the United States and Europe and keeps the company close to a deep pool of process chemists.
Asymchem's China Locations at a Glance
Most of the company's manufacturing and development capacity sits in four provinces or municipalities. The table below summarizes what each site is generally known for.
| Site | Region | Primary focus |
|---|---|---|
| Tianjin (TEDA) | Tianjin municipality | Corporate headquarters, API and drug product manufacturing, process R&D |
| Dunhua | Jilin Province | API and advanced intermediate manufacturing |
| Fuxin | Liaoning Province | API manufacturing and raw material production |
| Shanghai | Shanghai municipality | Process research, development, and technical services |
One pattern is worth noting: Asymchem separates early-stage research from large-scale production. Discovery chemistry and route scouting tend to happen at the Shanghai and Tianjin development groups, while commercial-scale API manufacturing runs at the larger industrial sites in Jilin and Liaoning.
Asymchem UK and the International Footprint
Asymchem's international layer is smaller than its Chinese base but has grown steadily. The company established a UK subsidiary that operates from the Discovery Park science campus in Sandwich, Kent, the same research park that once housed Pfizer's European operations.
The UK site is generally positioned as a development and client-facing hub for European customers rather than a bulk manufacturing plant. For research teams that want a Western point of contact without moving production out of Asia, that structure is often the appeal.
In the United States, Asymchem's North American operations are centered in the Research Triangle area of North Carolina, supporting business development, project management, and regulatory liaison work. The company has also signaled interest in adding Western manufacturing capacity over time.
Sites, addresses, and capabilities change as CDMOs expand. Confirm current details on Asymchem's official website or in its annual report before citing a location in a contract or regulatory filing.
What Each Type of Site Actually Does
Not every Asymchem location performs the same function. Understanding the split helps you route a project to the right team.
- Development sites (Shanghai and parts of Tianjin): route scouting, process chemistry, analytical method development, and scale-up studies.
- API manufacturing sites (Dunhua, Fuxin, Tianjin): kilo-lab through commercial multi-ton production, with specialized handling for high-potency compounds at select plants.
- Drug product sites: formulation, fill-finish, and finished dosage manufacturing for clinical and commercial supply.
- Client-facing offices (US, UK, and other regions): business development, project management, and quality documentation support.
Why Asymchem Locations Matter to Buyers and Researchers
Geography is not a cosmetic detail in pharmaceutical sourcing. It shapes regulatory inspections, tariff exposure, shipping time, and overall supply-chain risk.
- Regulatory history: Sites that have passed FDA or EMA inspections carry more weight for commercial programs than sites that have not.
- Logistics: Coastal Chinese sites ship faster to US and European ports than inland facilities.
- Risk diversification: A supplier with capacity in multiple regions is less exposed to a single disruption.
- IP and legal exposure: Where the work is performed determines which courts and trade rules apply.
Many peptide companies rely on contract manufacturers for the same reasons, even though peptide synthesis is a different technical discipline. Buyers who search for the best chinese peptide company usually discover that site location is one of the first filters they end up applying.
It also helps to compare ambiopharm locations when you are mapping peptide-specific capacity, because peptide manufacturers and small-molecule CDMOs are rarely interchangeable.
Investors: How the Footprint Ties to the Business
Manufacturing footprint is a core part of the investment case for Asymchem. Capacity additions, site approvals, and any shift toward Western production feed directly into revenue expectations.
Investors who follow asymchem stock on the Shenzhen exchange tend to track the same signals: capacity utilization, order backlog, and the regulatory status of individual plants. Peer comparisons come up too, and many analysts look at genscript stock when benchmarking Chinese life-science suppliers, even though GenScript's business mix is quite different.
How to Verify Asymchem Locations Yourself
- Check the company's official website for a current site list and addresses.
- Review annual reports filed with the Shenzhen Stock Exchange for subsidiary and facility details.
- Ask your project manager which specific site will run your program; this is usually named in the quality agreement.
- Confirm GMP status for that site through the relevant regulator's inspection database.
Quick Answers About Asymchem Locations
- Asymchem is headquartered in Tianjin, China.
- Its main Chinese manufacturing sites are in Tianjin, Dunhua in Jilin Province, and Fuxin in Liaoning Province, with development work in Shanghai.
- Asymchem operates a UK subsidiary based at Discovery Park in Sandwich, Kent, and US operations in North Carolina.
- Asymchem is primarily a small-molecule CDMO, not a peptide specialist, so it is not a direct substitute for dedicated peptide manufacturers.
