I. Inspection rules of raw material

i. Inspection of outsourcing metal semi-finished product: inspect mainly according to items of material bill and measurement of drawings. If inspection result is in line with purchasing bill, an Inspection Report of Outsourcing Finished-Product should be filled out, and the product is approved for warehousing.

ii. Inspection of rubber raw material:

1. Sampling inspection should be executed on incoming rubber raw material (three specimens per shift) in accordance with the national standard for sampling method and inspection standard.
