I may be reading this from the wrong side, so please correct me.
Since the end of June, China's customs administration has wanted the control answer on the export declaration itself. Announcement No. 77 reaches machine tools: lathes, milling machines and grinders. The exporter states in every case whether the goods are controlled, and where the goods resemble a controlled item, says in so many words that they are not. Nothing new becomes controlled. What moves is where the answer is written and whose name sits under it.
I do not file those declarations. In my own market that determination stays in our file, not on the form, so I read it as a question about my file.
A machine tool is decided on capability: the number of axes it will drive together in one cut, and how closely it holds position once the compensations are on. On the machines this industry sells, both follow the control option fitted, not the castings. The same iron leaves as a three axis machine for one buyer and as more for another.
So a not controlled determination is true of one configuration. We keep the option list and the software version beside it, and when a customer orders the option kit a year later we treat the kit as its own determination rather than a new export of the machine. I am not confident that is right. How does your file carry it?
