Not all chemical industrial units that file declarations to the OPCW are inspectable. Inspection thresholds are provided for each category of the declaring facilities and only those units are inspectable which carry out the activities above the thresholds. The inspection thresholds are generally 10 times the declaration thresholds. The inspection thresholds for Schedule 2, Schedule 3 and OCPF units are as follows:-
| Sl. No. | Category | Inspection threshold |
|---|---|---|
| 1. | Schedule 2 | 2A* - 10 kg/year 2A - 1 tonne/year 2B - 10 MT/year |
| 2. | Schedule 3 | 200 MT/year |
| 3. | OCPF units (DOC/PSF plants) | 200 MT/year |
