Our professional logistics services  facilitates cusoms clearance when importing chemicals  ,with this ,a better efficiency can be achieved .
---Professional packaging and labeling . 
We pay much attention to packaging and have much experienced in packing different chemicals with different packages .  Each chemical is carefully packed in containers pre-selected by us according to the property of chemicals and containers  .Plastic drums,iron drums,glass bottles,quality cartons and boxes ,vials are choosen depending on chemicals properties. Fluorinated HDPE bottles are utilized to ensure a proper and  safe packaging . These fluorinated containers resist permeation, paneling, odor emission, flavor and fragrance loss,  they are effective for packaging some corrosive ,flammable and toxic chemicals .Fluorinated HDPE bottles are suitable for containing most chemicals,including strong and weak acids, alcohols,aldehydes,alpiphatic hydrocarbons,aromatic hydrocarbons,halogenated hydrocarbons and aromatic ketones. UN-certified fluorinated HDPE  bottles (brand name JRB)produced by Boxmore International PLC (a branch of US based Chesapeake Corporation) are also used for safe packaging.  

Special service:

In order to better serve customers,our company has developed a Chemical HS Code searching App. With this App ,you can search for 1 billion chemical HS codes (Harmonized System Codes) in over 35 countries including China ,USA ,European Union,India,Japan,UK,South Korea , Canada,Russia etc. (Currently only include organic chemicals in Chapter 29). This is an unique tool to find almost any named chemical in the world with high accuracy and  efficiency .

Users can search for HS code by English chemical names (standard names or IUPAC names) or by registry numbers.

Finding a proper HS code for chemical is difficult ,as it requires knowledge in both chemistry and foreign trade.But this App makes it easy for any person to get a HS code with high accuracy in just a few seconds. 

If you are interested in this service,please go to page " HS code app " . To download the app,please use mobile phone browser to scan the two dimension code .
