Shanghai Qingchen Chemical Technology Co., Ltd. is a leading chemical enterprise specializing in the sales and distribution of high-quality organic chemical raw materials. With a focus on serving industries such as pharmaceuticals, agriculture, biotechnology, and research institutions, Qingchen Chemical is committed to providing superior products that meet the highest standards of quality and performance.

1.What products can Shanghai Qingchen provide for me?
Shanghai Qingchen is a chemical enterprise integrating sales and production.
Not only does it have its own laboratory, but the factory also has many long-term cooperative manufacturers in the industry. Therefore, our product range is very extensive.
We can provide organic raw materials, intermediates, customized products, scientific research reagents, etc., and ensure the provision of high-quality products at the most advantageous prices.

2.Are all the products of Shanghai Qingchen produced by itself?
As I mentioned earlier, we have our own main products. However, the production and research and development capabilities of a single factory are limited. So, we also cooperate with partner factories to offer a more diverse range of products.
Of course, for all our products, whether they are produced by us or by our cooperative manufacturers, we have a strict quality management system to ensure that all products meet the required quality standards.

3.How should I place an order?
Placing an order is very simple. Just send us an inquiry by email. It is best to provide detailed product information, such as the product name, CAS number, order quantity, shipping address, and your preference for the shipping method. We will reply to you within 24 hours.

4.Can you provide free samples?
Regarding free samples, due to the large number of inquiries and customer requests every day, we do not provide free samples. After all, both the cost of the samples and the freight are part of the expenses. If you want samples to confirm the product quality, we can provide sample orders. The minimum order quantity will vary depending on the product.

5.How can you ensure that the quality of the samples is consistent with that of the bulk goods?
To ensure the consistency of the sample quality, first of all, it is necessary to confirm the quality standards you are concerned about.
Then, we will determine the quality of the samples and the bulk goods according to your needs.
For customers with a relatively short order cycle, they usually choose to have the goods shipped from the same batch. Of course, if your order cycle is long, you don't have to worry about quality changes. Because we have very strict quality inspections for all our products.
We believe that quality is the foundation for the survival of a manufacturing enterprise.

6.What kind of shipping method should I choose?
Regarding the shipping method, common options include express delivery, sea freight, air freight, and railway transportation.
For samples, express delivery is basically the choice, which has the advantages of convenient receipt, door-to-door service, fast speed, and safety.
For bulk goods, you can choose according to your own needs. Air freight is fast but the freight cost is relatively high. Although sea freight takes a longer time, it has an advantage in terms of freight cost.

7.What other payment methods do I have?
The most common payment method is payment to a bank account, but we also accept payments through USDT and BTC accounts.
Regarding Western Union, Moneygram, and PayPal, due to the relatively high requirements for opening accounts and receiving foreign exchange in China, we are unable to provide these payment methods.

8.Regarding customized products, what information do I need to provide and how long is the cycle?
Customized products are our core advantage. We have 39 highly professional scientific research personnel, and our customers are very satisfied with our products.
For customized products, we need to know the product name, the product structure formula, and the specific requirements of the customer for the product.
After receiving the specific requirements, we need about a week to study the synthesis route, the cost of production raw materials, etc., and then we will provide a quotation according to the quantity of samples you need and your requirements.
After the order is paid for, we will arrange the production.
The production cycle depends on the difficulty of the product synthesis. If it is just a simple process, the cycle will be relatively short.
