0103·Calculated tax does not match for potassium chlorate

What this means

Potassium chlorate carries a specific tax computation reflecting its regulated status. Applying the general percentage rule produces a figure FBR does not agree with.

Why it happens

• The general value-times-rate calculation was applied.
• The rate has both a percentage and a per-weight component and only one was applied.
• Quantity was not in kilograms, so the per-weight component computed against the wrong base.

How to fix it

1. 1Read the full rate description — a compound rate needs both components summed.
2. 2Confirm quantity is in kilograms before computing the per-weight part.
