- This sorting efficiency can be achieved in product loops which are in a closed and controlled chain.
- The procedural experience of IFE08 showed that OSI specific operational needs are based on a tight and closed chain of custody.
- ‘product loops which are in a closed and controlled chain’ means manufacture and distribution cycles in which products circulate with a controlled reuse and distribution system, and in which the recycled material originates only from these entities in the chain, so that the unintentional introduction of external material is just the minimum technically feasible;
- Alternatively, for non-fillable materials and articles, such as crates and pallets that are handled in product loops in a closed and controlled chain in which all steps of manufacture, distribution and use are controlled, it may be sufficient to prove that contamination can be excluded when they are only used in contact with dry food such as fruits and vegetables.
- The Commission shall determine the conditions under which the concentration levels referred to in paragraph 1 will not apply to recycled materials and to product loops which are in a closed and controlled chain, as well as the types of packaging which are exempted from the requirement referred to in the third indent of paragraph 1.

- A safety assessment should verify that the recycling process fulfils these conditions. Alternatively, for non-fillable materials and articles, such as crates and pallets that are handled in product loops in a closed and controlled chain in which all steps of manufacture, distribution and use are controlled, it may be sufficient to prove that contamination can be excluded when they are only used in contact with dry food such as fruits and vegetables.
