Where And How To Find Chemical Suppliers In China?
Ask Us For Some Manufacturer Contacts!
If you are looking for chemical suppliers and manufacturers in China, please consider all available options.
If you are unsure about their reliability, please let us know.
We can help you run background checks on chemical suppliers in China!
Now, read on.
1. You Can Always Search Chemical Suppliers On Google
Google is the world’s most powerful search engine. If you search for a keyword, you will see a vast amount of information displayed daily.
If you are looking for a new product from a new supplier, it is essential to run a background check.
We may have to post a new topic later: How to Run Background Checks on Chemical Suppliers.
2. Search For Chemical Suppliers On Alibaba
Updated on August 17th, 2021: Alibaba is closing accounts for all pharmaceutical suppliers on Alibaba.com. Please note this change.
Skip this section!
As we all know, I suppose Alibaba is a comprehensive B2B platform, second to none.
Chemical suppliers on Alibaba are mainly trading companies, but there are also major manufacturers, such as Jiudian Pharma, which has been on Alibaba for over 5 years.
Most suppliers are reliable, and Alibaba is doing a good job keeping those companies in check.
2.1. Once a complaint is filed against the suppliers and the case is severe, Alibaba can close the suppliers’ e-shop, and the 5000 USD yearly fee will be in vain.
Alibaba will run a basic background check on suppliers before they can start e-commerce on their platform.
2.2. Buyers have reviews on each transaction they made, good or bad; you can read them for yourself.
We can not say that all 5-star reviews are trustworthy, but at least they say something.
Chemical importers understand the difficulty of each customs clearance, and it is not easy to fake an international chemical transaction.
2.3. You can check the membership years for each supplier. The longer their membership years, the more trustworthy they should be.
But there is always a but.
However, an Alibaba supplier with over 10 years of experience doesn’t necessarily mean they provide superior service; they were just there a little earlier.
2.4. You can check the Transaction value numbers for each supplier, and the data also indicates reliability.
Sorry, we almost forgot Made-in-China.com. You can also try MIC, but MIC’s specialties are not in chemicals, mainly in machinery or other stuff.
3. Attend CPHI China and API China for more chemical vendors
The exhibitors at API China are generally more likely to be direct manufacturers than those at CPHI.
API China is a fair for the Chinese domestic market. Direct chemical and pharmaceutical manufacturers mostly exhibit at API China, and only a few traders are present.
Those traders offer better prices because of their strategic relationships with major manufacturers.
When they learn that prices may rise, they will buy all the goods in stock from the factory before prices increase.
Why do we say API China exhibitors are relatively preferable?
Check the reasons below:
3.1. Exhibitors are mainly direct manufacturers with better control over the lead time, quality, etc.
As a result, there are fewer exhibitors than there are at CPHI China.
CPHI China can have ten times as many exhibitors as API China. If you want to work with more reliable chemical manufacturers and factories, come to API China, where the risk of a bad choice is lower than at CPHI.
3.2. API China mainly targets Chinese trading companies and manufacturers.
Purchasing managers may discuss prices and the quality of certain products with exhibitors from stall to stall.
They sit down together, talk, and maintain relations.
The chemical and API circle is small, and you haven’t had a chance to get to know every factory for very long.
Everyone will soon know if any of the chemical suppliers cheat, so all API China suppliers will do their best to maintain their good reputations.
At CPHI China, major API manufacturers are always present in the W1, W2, E1, and E2 Halls, as well as in other Halls with lavish, radiant decorations.
But you will find more trading companies.
Technically, over 90% of the exhibitors on CPHI are trustworthy.
I cannot guarantee 100%, as some importers may have had bad experiences with certain suppliers exhibiting there; I can’t rule them all out.
Therefore, importers seeking reliable API suppliers should consider auditing their manufacturing facilities in China.
It will give them more confidence in choosing the right suppliers.
4. You can find reliable chemical suppliers on chemical B2B sites
4.1 Pharmaoffer.com
This website lists many prominent and well-known chemical & API suppliers, most of which are trustworthy.
In the left sidebar, you can search for products by chemical names or CAS numbers and filter search results by supplier type, country, and documentation to choose the right supplier.
Many reliable chemical and pharmaceutical suppliers in China are advertising on this website.
4.2 pharmacompass.com
This site displays suppliers’ registration status, including FDA/CEP, USDMF/EDMF, and other relevant certifications.
Take Bacitracin API as an example. If we type BACITRACIN and click search, we can see a page like the one below, with the Number of API suppliers, USDMF, CEP/COS, etc.
Find details by yourself.
Generally speaking, Chinese suppliers are more competitive.
4.3 chemnet.com
Chemnet.com is part of www.toocle.com. You can also search for it on Toocle.com.
The key to using chemnet.com.cn is in Chinese. You can search by CAS number and product name (in Chinese); the supplier name will then appear.
Most suppliers on chemnet.com.cn are factories; they often supply intermediates rather than APIs.
Chemnet was thriving around 2010 or earlier, but over the years, its paid membership gradually declined as cheaper or even free chemical B2B sites emerged.
Additionally, Chemnet has not been offering any attractive services to retain its paid members.
Their business scope includes chemical advertising, building websites, web hosting, domain name services, etc. Still, many factories rely on Chemnet’s advertising to reach new chemical buyers.
4.4 chemicalbook.com
chemicalbook.com is a rising star among chemical B2B portals.
Their main paid customers are reagent companies, small labs, and traders, so you know the order quantities are comparatively tiny, and suppliers there sell their chemicals in milligrams (mg), grams (g), 10g, etc.
If you check the front page of ChemicalBook, you will see that all its sponsored members are reagent companies. However, its daily traffic is around 16 thousand. (updated on 2025.10.16)
4.5 Lookchem.com
Lookchem.com—I’m not sure how to put it, but we are not big fans of their yearly fee, which is roughly the same as Alibaba’s, around 5000 USD per year.
Paid members are mainly trading companies, approximately 3/4.
Importers and buyers can verify for themselves.
Please note that their daily organic traffic is less than 1,000, which is only 1/16 of that of chemicalbook.com. (updated on 2025.10.16)
5. Search Pharmaceutical Manufacturers on FDA Websites
Below, we will only list three symbolic sites:
1. Chinese FDA website;
2. US FDA website;
3. EDQM website.
You can always check similar websites, such as the Indian FDA, Australian TGA, Japanese FDA, and other relevant regulatory bodies.
This allows you to find the registered and approved API suppliers in related countries.
5.1. www.nmpa.gov.cn
On this site, you need to know Chinese characters to recognize supplier names and distinguish between them.
You can enter keywords in either Chinese or English.
The suppliers on this website are 99% reliable. You may ask who the 1% is. Hmm, there are just manufacturers with bad reputations.
Please note that all suppliers you get on the CFDA website are manufacturers, not traders.
5.2. www.fda.gov
We believe all API importers should be familiar with the US FDA, renowned for its strict oversight of applicants.
If you find FDA-approved Chinese applicants on fda.gov, 9 out of 10 are reliable, ok?
The photo above is a screenshot of the FDA website search interface.
You can search by Active Pharmaceutical ingredient, company name, NDC Number, and other relevant criteria. Happy hunting!
The photo below is the FDA certificate verification interface.
If you are unsure of the authenticity of your supplier’s FDA certification, you can verify it by clicking on the link in the photo.
5.3. www.edqm.eu
Above is the supplier search interface of the EDQM website.
Click the photo link to visit the EDQM website and search for suppliers of specific products. If you find Chinese suppliers on EDQM, they are reliable, right?
Europe’s supervision of pharmaceutical manufacturers is as strict as the US FDA.
If you have difficulty finding Chinese active pharmaceutical ingredient suppliers approved by EDQM, please click the photo or the EDQM search interface.
6. Referrals From Your Current Suppliers
Last but not least, this is also an essential way to find new, reliable suppliers in China.
Generally speaking, current Chinese suppliers know the chemical industry better than foreign importers and can provide insightful ideas to verify the reliability of your new suppliers.
So, buyers and importers, be kind to your current suppliers. They have already earned your trust and are your hidden wealth.
Sometimes, they can arrange for an attorney to file a lawsuit against you if Chinese suppliers have cheated you.
Of course, there are other ways to find reliable suppliers, such as visiting potential suppliers, auditing the factory, and having a sit-down conversation.
If readers have different or better ideas, they are welcome to comment, and we can discuss them together. As the Chinese economy grows and the internet becomes more popular, there will be less room for business cheaters.
We took steps to keep buyers’ and importers’ businesses as safe as possible.
We invite you to report cheaters to us, and we will list them on our website.
