We have received some material (1000 pcs) from our customer in Germany for processing. The material was send as free issue and we paid custom duty + CVD on the value declared by customer (US$3000). We have processed part of the order (100pcs), the quality of which was not accepted by customer. Now customer wants us to return the 900 pcs back to them. How do we do this? What is the correct procedure?
