一个天津做钛白粉的企业，美国的买家让这个企业给她寄样品。因为是白色粉末（white powder），所以空运快递需要做样品的DGM鉴定。 美国买家提供了Fedex的快递帐号，愿意承担运费。买家购买的意向很明确。但是双方就DGM的检测费用产生分歧。大家一起看看，你觉得业务员Ann哪些地方的做法值得商榷或改进。 下面是双方的邮件往来（按时间顺序）： 买家：（提供了快递帐号，语气很礼貌） Dear M. Ann: Thank you for your continued information. Please advise status of the sample. Please feel free to utilize our FedEx account (X917-0X70-X) to facilitate the shipping. I look forward to your return reply and confirmation. 业务员： Dear XXX, I am glad to reply in quickly,I come to office on Monday,I will confirm the accounts from you right now,but the Titanium Dioxide belong to white power so need DGM certificate everytime by air I think you can understand me,ok? In order to send free sample pls pay for USD 75 as DGM certificate,our bank information as follow,pls as soon as quickly. 买家：（开始有些疑惑） Dear Ann: Thank you for your reply. 1. We have already provided our account number for our FedEx account. This way the freight does not cost you anything. 2. I don’t understand what you are talking about concerning the $75 cost. We have asked other Chinese suppliers to send us a sample and in most cases, we don’t even have to supply them with our FedEx account number. 3. We consume over 80 containers annually. If you are not interested in such business, please let us know. 业务员： Dear XXX, Thank you for your reply, 1.I am glad to business with you very much and I known you're high quality buyer so I would like send free simple to you, you can also visit our website:http://tjhwdx.en.made-in-china.com we have get SJS certificate 2.Titanium Dioxide belongs to white powder must be get DGM certificate can export by air,and this test must be done at a time per air,I guess your suppier sent sample didn't the same sample by air,pls confirm. 3.The sample is free but USD 75 just belongs to DGM certificate by per air. Thanks Ann 买家：（开始不耐烦） Hello, I would like to thank you for your efforts, unfortunately for the time being we have 8 Titanium dioxide manufacturer are sending us samples via air without any charges, your company is the only one. I regret to inform you for now we are no longer require your sample.

If you need any information about our company please go to our WEB site. 业务员： Dear XXX Thanks for your reply in timely, titanium dioxide belongs to General cargo isn’t a dangerous goods but during Shanghai World Expo like liquid and powder chemicals by air , the DGM certificate must be done! if you didn't trust me,pls ask your supplier or the FedEx in china, telephone NO:86-800-988-1888 or 86-400-886-1888 maybe he can answer you.
