We will ship 4 sets of hot air circulation ovens to Bangladesh for drying tubes in pharmaceutical industry recently.

This is our broker in Bangladesh, he orders our dryers frequently.  He usually visits our factory in the past. But now difficult to visit Yutong since the outbreak of epidemic diseases. 

How to test the dryers that meet customer's requirement? Especially that during Covid-19 epidemical situation period? This is also the misgiving as a broker, he has the responsibilities for end users. Customer can not immigrate to China. The machines are approved by SGS authenticates, the third party monitored and controlled the quality according to preliminary URS.
