Risks

C. Thorrez Industries carries two of the six risks to manage.

Exhibit 1

Six risks to manage before award.

Each risk and the suppliers it affects

	Risk	Affects
1	Own pages give 225,000 and 366,000 sq ft; confirm real capacity before award.^{1, 3}	Kenona
2	Certifications page still lists ISO/TS 16949:2009; no IATF expiry or registrar shown.¹¹	C. Thorrez Industries
3	Section 232 puts 25% duty on covered imported auto parts.²⁹	Every bidder
4	C. Thorrez Industries: no certificate expiry dates or registrar names were found on the company’s pages or the third-party sources checked. These should be verified in the IATF Customer Portal or with the registrar.¹¹	C. Thorrez Industries
5	X-L: the business is not BBB accredited.³⁰	X-L
6	Michigan Production Machining, (MPM): ZoomInfo reports a planned office move in May 2026 from Roseville, Michigan; this is a risk to the site record.³¹	Michigan Production Machining, (MPM)

Appendix A · Scoring rules

How each criterion was confirmed

Two websites confirm a criterion; p. 8 shows the finding behind each cell.

Criterion	Looked at
IATF 16949	Certificates
ISO 9001	Each supplier’s findings on ISO 9001
Automotive precision	Processes, Machining centers
CNC precision machining	Finishing in-house
Certificates	Each supplier’s findings on certificates

A criterion counts as confirmed when two websites back the supplier’s finding for it; one website shows, but is not counted.

Each cell is the supplier’s best finding for the criterion: two websites first, then one website, then websites that disagree.

A supplier’s total is the criteria two websites confirm, out of 5.
