Limited International Bidding Method

Acording to ADB, Limited international bidding (LIB) is essentially ICB by direct invitation without open advertisement. it may be an appropriate method of procurement where:
- There is only a limited number of suppliers,
- The amount of the contract is not large enough to attract foreign suppliers and contractors through International competitive bidding (ICB), or
- Other exceptional reasons may justify departure from full ICB procedures.

Under Limited International Bidding, borrowers shall seek bids from a list of potential suppliers broad enough to assure competitive prices, such list to include all suppliers when there are only a limited number. Domestic preferences are not applicable in the evaluation of bids under Limited International Bidding.
In all respects other than advertisement and preferences, ICB procedures shall apply.
This method is simpler than ICB, but it has a potential risk about corruption. So many donors do not want to apply this.
