3. For products not yet covered by metrication circulars and standards, soft conversion to metric units is allowed until such time that manufacturers can adopt rational metric units on an industry-wide basis.
4. The Bureau of Product Standards shall continue to guide industries in arriving at agreements on sizes using metric units and related implementing guidelines at the earliest time practicable to such industries.

9. The Bureau of Product Standards in coordination with DTI regional and provincial offices shall monitor compliance with these guidelines by manufacturers, importers, and sellers.
