This substance may be assigned to UN No. 2735 only if an exemption from Class 1 can be made on the basis of test results (see test series 6 of the UN Manual of Tests and Criteria). 

Based on the test results available, it can be assumed that aqueous solutions of hydroxylamine in "soft" packagings (e.g. fibreboard box with PE bags as inner packagings) can be exempted from Class 1. 

To what extent an exemption of aqueous solutions of hydroxylamine in other packagings, which represent a stronger inclusion, is possible, can be decided only after testing according to Test series 6.

It follows from the above that not every packaging listed in the packing instruction for UN No. 2735 is suitable for the carriage of aqueous solutions of hydroxylamine. 

Only packagings that have passed Test series 6 and which are eligible for exemption from Class 1 in accordance with 2;1.5.2 may be used.
