[Ferro-alloys.com]It’s our great honor to witness the wonderful speech on the topic of “Customs Code Classification and Specification for Cored-Wires Products Export & Its Practical Guiding Significance”, which presented by Professor Zong from Shanghai Customs College.

He clearly explained the development of import-export products classification emerging process from disordered condition to a unified one.

Complementary principles

1. Coordinate system annotation.
2. National letter annotation.
3. Official classification.

Later, Professor Zong briefly introduced the characters, categories and types of cored-wires products. Then, he analyzed some controversial issues about products classification.

1. Is there any certain regulation?
2. Is there any negotiation system?

From the core materials perspective, Professor Zong pointed out that the controversial focus on the final definition of 7202 ferroalloys or unlisted 3824 chemical is whether or not the core material is ferroalloys. The point is that whether its composition meets the requirement and whether it’s a kind of alloys.
