01

Lock in the rate declared at customs

The exchange rate declared at customs can differ from the invoice rate. You enter each declaration at the customs rate, and the rate and its TRY equivalent are locked in when you save. Import and export declarations share one list, separated by direction, and each one holds its registration and customs details, Incoterm, and transport document.

Decide who can register a declaration

Opening a declaration and registering it are separate permissions, so you can give the customs broker and your foreign trade coordinator different roles. A registered declaration can't be deleted, only canceled.

02

Skip the currency math on import costs

Freight in USD and brokerage fees in TRY can sit on the same declaration. There are 11 cost types, including customs duty, freight, and brokerage, and each cost is recorded with its own currency, exchange rate, document number, and vendor. The cost type sets whether a cost goes into stock cost, and you can change it. Import VAT is excluded by default, and the screen also flags it with a warning.

  • Add costs while the declaration is a draft or registered; costs on closed or canceled declarations can't be changed
  • Hover over the TRY equivalent to see the exchange rate and its source

03

Allocate import costs to stock, down to the cent

Allocate each cost on its own basis: freight by weight, insurance by value, storage by quantity. IWB spreads the costs across the lines of the stock entry the goods arrived on and updates the unit cost. Applying costs to stock cost happens only once and can't be reversed, so wait until every cost is in.

  • Rounding differences go to the largest share, so the total matches to the cent
  • Allocation by weight isn't possible if any product's weight is unknown
  • The share of goods already sold isn't added to stock; it's shown separately
  • The declaration must be matched to its stock entry before costs can be applied

04

Import VAT entries come ready to post

For a registered import declaration, IWB prepares a draft journal entry for the import VAT: debit 191 Input VAT, credit 320 Accounts payable (Turkish Uniform Chart of Accounts). The credit line is linked to the contact who billed the cost. The entry stays a draft until your accountant posts it.

If you can't deduct the VAT

You can include the VAT line in cost instead. The amount then goes into stock through cost allocation and isn't posted to 191 a second time.

05

See outstanding export proceeds and the deadline

Track expected, received, and remaining proceeds in the declaration currency. Record each installment against its export proceeds acceptance certificate (İBKB) or foreign exchange purchase document (DAB). If proceeds arrive in a different currency, you must enter the amount that counts toward closure. The deadline is 180 days from the actual export date and can be changed; overdue declarations are flagged "Proceeds overdue" in the list.

  • If the last day falls on a public holiday, the deadline moves to the next business day
  • IWB suggests the amount counted toward closure at the Turkish Central Bank (TCMB) buying rate; the figure on the İBKB prevails
  • You can keep recording proceeds after the declaration is closed

06Document flow

Cost and import VAT come from one declaration

You link the declaration to the stock entry the goods arrived on, and costs are allocated across that entry's lines. For a registered import declaration, IWB prepares a draft journal entry for the import VAT.

What you can do with Foreign Trade

  • Micro-exports (ETGB)

    Mark micro-exports sent by courier or post as a simplified declaration (ETGB); the list shows them with their own badge.

  • Attached documents

    Attach the certificate of origin, A.TR movement certificate, bill of lading, and customs broker's statement to the declaration.

  • Change history

    Every field change, such as a new registration number or declaration exchange rate, appears under the field's on-screen name.

  • Who sees what in the list

    Limit a role to "only my declarations" or "imports only"; the restriction applies in the list.

  • Field masking

    Mask the rate, value, proceeds, and registration fields by role.

  • Freight at goods receipt

    A single freight line entered at goods receipt is also allocated across the stock lines.

  • Export invoices

    When you issue an export invoice, IWB checks each line's 12-digit Turkish tariff code (GTİP), the Incoterm, and the VAT exemption code.

  • Document flow

    The document flow shows the declaration linked to the stock entry the goods arrived on.

08Compliance

Deadlines and calculations follow Turkish rules

You enter the registration number and exchange rate from the declaration filed at customs; IWB doesn't send declarations to the customs system.

  • Export CircularExport proceeds must be brought back to Turkey within 180 days of the actual export date; if the last day is a holiday, the next business day applies. For exempt procedures, you enter the deadline manually.
  • Customs Regulation art. 51IWB doesn't suggest a rate for converting the customs value; you enter it from the declaration.
  • VAT Law art. 29Import VAT is posted to account 191 for deduction, with the offsetting entry in account 320.
  • Incoterms 2020IWB validates the Incoterm code on export invoices.
  • Proceeds received in another currency close at their İBKB equivalent; İBKB and DAB numbers are kept on the record.

Frequently asked questions

Is Foreign Trade a separate module?

No. It's the "Customs declarations" section of the Purchasing module. The section appears in the menu only for users with permission to view declarations.

Does IWB send declarations to the customs system?

No. You enter the declaration in IWB by hand and type in the registration number you get from customs. There's no connection to the customs system.

Can I add costs later?

Yes. Import invoices can arrive late, so you can add costs while the declaration is a draft or registered. But costs can be applied to stock cost only once, and that can't be reversed. A cost added after that doesn't reach stock.

Can I track the repatriation of export proceeds?

Yes. You track expected, received, and remaining proceeds in the declaration currency. The deadline is 180 days from the actual export date, and overdue declarations are flagged "Proceeds overdue." You enter İBKB and DAB details manually, and recording a collection doesn't close the proceeds automatically.

Is a declaration linked to invoices and orders?

The document flow links the declaration to the stock entry the goods arrived on. IWB doesn't link it to orders or invoices automatically.
