This substance may be assigned to UN No. 3260 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 hydroxylammonium chloride 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 hydroxylammonium chloride 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. 3260 is suitable for the carriage of hydroxylammonium chloride. 

Only packagings that have passed Test series 6 and which are eligible for exemption from Class 1 in accordance with 2.1.3.5 may be used.
