How do I double-check the calculated Import Declaration Fee for a UK invoice?

To double-check the Import Declaration Fee (IDF) for a UK invoice into Kenya, you need to verify that Kenya Revenue Authority (KRA) has correctly applied the official rate to the correct customs value. IDF is a standard import charge applied through the KenTrade Single Window System and is based on the CIF value of the goods.

---

1. Confirm the correct IDF rate

The IDF is generally calculated as:

• 2.5% of CIF (Cost + Insurance + Freight)

So first confirm the correct rate has been applied and that no outdated or incorrect percentage is used.

---

2. Rebuild the CIF value yourself

Before checking IDF, verify the base value:

• Invoice value (UK supplier cost)
• International freight charges
• Insurance (if applicable)

👉 CIF = Invoice + Freight + Insurance

If CIF is wrong, the IDF will also be wrong.

---

3. Recalculate the IDF manually

Use this formula:

• IDF = CIF × 2.5%

Example:

• CIF = 100,000
• IDF = 100,000 × 0.025 = 2,500

Compare this result with what appears on your KRA entry.

4. Check the official KRA entry (CUSDEC)

Through your clearing agent, confirm in KenTrade:

• CIF used in the declaration
• IDF line item applied
• Final tax breakdown

This is the official system record used by KRA.

---

5. Quick reverse-check method

You can also reverse-check:

• KRA IDF ÷ 0.025 = Implied CIF

Then compare that CIF with your invoice value.

If they differ, KRA may have adjusted the valuation.

---

6. Common reasons IDF looks incorrect

• Incorrect CIF (freight or insurance miscalculated)
• KRA revised customs value (valuation adjustment)
• Incorrect or outdated rate applied
• Data entry error by clearing agent

---

7. Bottom line

To verify IDF accuracy, always:

• Confirm CIF is correct
• Apply 2.5% rate
• Cross-check against the official KenTrade/KRA entry

Any mismatch usually comes from valuation differences, not the IDF formula itself.
