User Experience:
Our company is based in Singapore. We trade nonferrous metals such as Aluminium on a worldwide basis. We have been purchasing from this trading company/stockist (Jiangsu Yiwanhong International Trading Co., Ltd.) large quantities of 7075 round bars prior to the incident that will be described in the following.

Our contacts throughout the years were Mr Frankie ( and Ms Mango (

For our customers in Germany, we have always been purchasing according to EN 755 Standard. In this particular order, placed on 15 May 2019, the mechanical values and hardness had to have specific values that were higher than the European Norm describes.

It was agreed to purchase the round bars at Henan Mingtai, a large Aluminium rolling and extrusion mill in China ( & and then cut them to size at the warehouse of Jiangsu Yiwanhong International Trading Co., Ltd.

In order to ensure the correctness of the material and that all mechanical values have been reached as per the written and confirmed contract, we engaged a third party to do the material testing. This third party testing was done to be SGS in Nanjing, one of the largest laboratories in the world to conduct these tests. The testing was supposed to be conducted on the extruded round bars before they will be cut to size at the warehouse of the trading company.

After completion, we have compared the values indicated on the SGS certificates with the values indicated on the Mill Certificates and they matched, so we gave the green light to ship out the material.

After arrival in Germany, we kept the material in our warehouse for a while. As time passed by, we received various claims coming in from other customers that the mechanical values do not match the actual certificates, so we took some of the material from this order a conducted ourselves some random testing at SGS in Germany on 13 January 2020.

The results were shocking, all the values that have been indicated on the certificates by SGS in China were within the requested range, whereas SGS in Germany has tested the cut to size pieces out of specification.

After this has come to light, we started to investigate. We have sent samples to SGS in China to do another test, contacted Mingtai directly in order to find out more about this issue and how the testing has been conducted.

Mingtai’ s help in this issue was already nonexistent, but from this point on the Jiangsu Yiwanhong International Trading has more or less seized communication with our company.

SGS has been very helpful and they have confirmed two things: 1) After testing the material we sent to them from our customers in Germany, they came up with the same failed values as their colleagues at SGS Germany have come up with. 2) Jiangsu Yiwanhong International Trading has only sent them samples, there were no SGS stamps to be found on any of the cut to size pieces in Germany. There was no proof that the tested material and the shipped out material actually are the same.

In conclusion, this means the following: Jiangsu Yiwanhong International Trading has sent some material to the SGS Lab that was perhaps produced by Mingtai with the correct values, but which was never actually cut from the material that has been sent out to us under this order to Germany. The trader cheated us with a very high criminal potential. The trading company in question shipped out material that was not even produced according to EN Standard and like this, they could get rid of it easily. SGS confirmed that the tested bars sent to them prior to shipment and the ones that we sent to them were not the same.

If you have any questions, please contact us via this website. We have all the documents and communication proving that the tested material and the actually received material are two completely different materials. Sufficient 3rd party testing reports are available to prove our point. Not only conducted by SGS but other accredited laboratories in Germany.

Both our client and our company got into massive financial problems due to this incident and we now hired a debt collecting company to get the trader to speak to us again. They do not revert to any phone calls, emails or WeChat messages anymore. The goods cannot be sold anywhere anymore as they are completely out of specification. They do not meet the special requested values but are also below the EN Standard for those products.

User Recommendations:
This is the 3rd incident with a Chinese supplier that we report here on this webpage. We have been purchasing Aluminium by now for more than 10 years from China. If you only look for the price, this is your country. But in our experience, buying from China never comes problem-free. However, this incident here is just beyond words. There are many things you can do to avoid being cheated, but 100% you can probably never guarantee unless you are physically there a monitor every step of the order. We hope this report helps other companies to understand the highly criminal nature of this company. As mentioned before, any questions, please contact us through this website and we are very happy to disclose any sort of additional communication/certificates/contracts/letters/contacts, etc.
