Answer Summary

What this page answers

Question

What is customs value and how is it calculated?

Customs value is not always the same as invoice value or product cost. Depending on destination rules, it may be FOB goods value, CIF goods plus freight plus insurance, or a manual declared value with specific adjustments for assists, packaging, and commissions.

Formula / Criteria

What to check

FOB: customs value = product value. CIF: customs value = product value + freight + insurance. Manual: customs value = product value + freight + insurance + assist value + packaging + commission. Result feeds into the Import Duty Calculator.

FAQ

Common questions

Is customs value the same as invoice value?

Not always. Customs value may add freight, insurance, assists, packaging, and commissions depending on destination rules.

What is FOB basis?

FOB (Free On Board) uses the goods value at the port of export as the customs value, before international freight and insurance.

What is CIF basis?

CIF (Cost, Insurance, Freight) includes goods value plus international freight and insurance.

Should I include freight in customs value?

It depends on the destination valuation basis. CIF includes freight; FOB usually does not.

Are assists part of customs value?

In many valuation systems, assists (such as tools, dies, or materials provided by the buyer) can be part of customs value. Verify destination rules.

Can I feed this into an Import Duty Calculator?
