If you want us to provide you an inspection certificate, we will have to apply it from an inspection company. We work with Intertek, not SGS.
This kind of request must be required when you send your requirement.
For your information, it is costly to apply for this kind of certificate. It will be more than 1000 USD.
We can contact Intertek and ask them to come to our site and make this certificate before the shipment of your container. We will have to update the price of the zinc powder as per Intertek invoice we will be charged.
1st of all, please check with your customer if he still wants this certificate and accepts price increase.
If so, we will check with Intertek precise cost and let you know in order to receive your final acceptance.
I wait for your comments.
