For companies that manufacture and export, one of the strongest incentives is the inward processing regime: importing the inputs of an export product without customs duty and VAT, processing them, and re-exporting. The document for this regime is the DIIB. Used correctly it delivers cost and cash advantages; mismanaged it leads to repaying the unpaid taxes with interest. This guide explains what DIIB is, its two systems, and commitment management in plain terms.
DIIB (inward processing authorization): an export incentive document that allows the inputs (raw materials, auxiliary materials, packaging) used to produce an export good to be imported without customs duty and VAT. In return, an export commitment is given for a set period.
Two systems: conditional exemption and drawback
- Conditional exemption: no tax at import (usually against a guarantee). If the commitment is not met, tax plus interest is collected. It has the highest cash advantage and is the most common system.
- Drawback: tax is paid at import and refunded after the export is realized and the commitment is closed. It requires paying tax upfront but the guarantee burden differs.
The export commitment and closing
The core of DIIB is the commitment: in return for duty-free imported inputs, a certain amount of export must be made within the document period. The commitment is closed with the customs declarations that prove the export. The critical point is matching: which export counts under which DIIB, and against how much input, must be traceable. Conditions such as the foreign-currency usage ratio are also considered at closing.
Benefits for the exporter
- Cost: the customs duty and VAT burden on inputs is removed, making the export price competitive.
- Cash flow: under conditional exemption, tax is not paid upfront, preserving working capital.
- Competition: lower input cost is an advantage in international price competition.
Manage DIIB as a discipline of calendar and matching: track the document period, imported input quantity, and realized exports in one place. Customs declarations are the proof for closing the commitment; archiving them fully makes closing smooth.
Risks and common mistakes
The biggest risk is failing to close the commitment in time: the tax on the duty-free inputs is then collected with interest and a penalty arises. Wrong matching between imported inputs and exports, overlooking the foreign-currency usage ratio, and incomplete closing documents lead to the same outcome. Do not leave DIIB tracking at the edge of the operation.
Tracking DIIB in the operation
The difficulty of DIIB is not the regulation but the tracking discipline: how much was imported under which document, how much was exported against it, and when the commitment expires. In a trade operations layer like Sighthem, DIIB can be linked to shipment and export records; shipments realized against the export commitment and the remaining quota are tracked on one screen, so closing stops being a surprise.
Frequently asked questions
What is DIIB (inward processing authorization)?
DIIB is an export incentive document that allows raw materials, auxiliary materials, and packaging used to produce export goods to be imported without customs duty and VAT. The goal is to process the imported inputs and re-export, lowering the exporter's cost and cash pressure.
What is the difference between conditional exemption and drawback?
Under conditional exemption no tax is collected at import, but if the export commitment is not met, tax plus interest is collected; a guarantee is usually required. Under the drawback system, tax is paid at import and refunded after the export is realized and the commitment is closed. Most manufacturer-exporters prefer conditional exemption for the cash advantage.
What does the export commitment mean?
In return for duty-free imported inputs, it is the obligation to export a certain amount within the period stated on the document. The commitment is closed with the customs declarations that prove the export occurred. A commitment not closed in time triggers collection of the unpaid taxes with interest and a penalty risk.
How is a DIIB commitment closed?
Exports realized within the document period are matched with the imported inputs, and a closing application is filed with the relevant customs declarations. Accurate, complete matching is critical; which export counts under which DIIB must be traceable, otherwise a quota gap and extra tax arise.
What are the most common mistakes?
Missing the commitment period, failing to match imported inputs with exports correctly, overlooking the foreign-currency usage ratio, and gathering incomplete closing documents are the most common mistakes. They lead to a penalized closing, that is, collection of unpaid tax and interest.
