Seed Contaminants and Tolerance tables
All seed consignments imported into Australia for all end uses must meet the AQIS standards for seed contaminants and tolerances.
These standards are detailed below:
1. Soil
Seed must be free of soil. Seed contaminated with soil discernible to the naked eye must be cleaned, re-exported or destroyed. Soil is not always readily visible, but 0.1% has been adopted as the standard maximum tolerance.
2. Restricted and Prohibited Seeds

Table 2. Nil Tolerance for Prohibited Seed
AQIS defines a prohibited seed as:
a) Any species exceeding the tolerance levels for restricted seeds (see Table 1); OR
b) Any species listed on ICON as prohibited (including but not limited to those listed in Table 2); OR
c) Any species not listed on ICON or Schedule 5 (‘Permitted Seeds List’) of the Quarantine Proclamation 1998; OR
d) Any seed that cannot be identified to species level.
NOTE: Contaminant seeds not listed on ICON or not identified to species level require an assessment by AQIS Plant Quarantine Program prior to any action being taken.
The following tables are not an exhaustive list of prohibited weed species. Please search the ICON database to determine whether a particular species is prohibited.
