What is TTI in import?

Total Tax Incidence — the sum of CD, RD, SD, VAT, AIT and AT as a percentage of the assessable value. It shows the total customs bill for an HS code.

Which exchange rate does customs use?

Customs uses its own rate for the week, published by Bangladesh Bank / NBR, which can differ from the bank selling rate. Enter that rate for the most accurate figure.

Is AT the same as AIT?

No. AIT (advance income tax) is adjusted against income tax. AT (advance tax) is a VAT-related tax that VAT-registered importers can claim back as credit.

Why does my C&F agent quote a different figure?

Customs may assess a higher value than your invoice (minimum or tariff value) and agents add their fees and port charges. Use the local costs section to include them.

How import duty is calculated in Bangladesh

Customs first finds the assessable value (AV): the CIF value (cost + insurance + freight) converted to taka at the customs exchange rate, plus a landing charge. Every duty is then worked out in a fixed order:

Customs duty (CD) = AV × CD rate (0%, 1%, 5%, 10%, 15% or 25%).
Regulatory duty (RD) = AV × RD rate.
Supplementary duty (SD) = (AV + CD + RD) × SD rate.
VAT = (AV + CD + RD + SD) × VAT rate, usually 15%.
Advance income tax (AIT) = AV × AIT rate.
Advance tax (AT) = (AV + CD + RD + SD) × AT rate.

The sum is the total tax incidence (TTI). Finished consumer goods commonly carry a TTI of 58% or more of AV; basic raw materials and capital machinery are much lower.

Example

Goods of $10,000 FOB + $800 freight, insurance 1%, at ৳122/$: CIF ≈ ৳13,30,776 and AV with 1% landing ≈ ৳13,44,084. At CD 25%, RD 3%, VAT 15%, AIT 5% and AT 5% the TTI comes to about ৳7,87,600 — 58.6% of AV.

What you get back

VAT and AT are claimable as input tax credit in your Mushak-9.1 return if you are VAT-registered.
AIT is adjusted against your final income tax.
CD, RD and SD are a real cost and belong in your product cost.

Find your exact rates

Rates depend on the 8-digit HS code of the product and change every budget. Look up your HS code in the Bangladesh Customs operative tariff, then type the rates into the calculator.
