Most viewed topic under segregation on this site is Acids and Alkalis. Most of the Acids and Alkalis fall under Class 8 ; this makes it imperative that we must look in Column 16 of DGL to check the segregation requirements.
Acids and Alkalis are not allowed to be packed in the same outer packaging or stowed in the same container.
When both Acids and Alkalis belongs to class 8 they may be kept together under below clauses of IMDG Code
- Limited Quantities different Packaging – No Segregation applicable
- Excepted Quantities different Packaging – No Segregation applicable
- Same outer packing or same container – As per 7.2.1.13.2 of IMDG Code
- Same outer packing in Limited Quantities -As per 3.4.4.1.2 of IMDG Code
Refer 5.4.1.5.2.2 & 5.4.1.5.11.3 of IMDG Code for dangerous goods declaration of Acid and Alkali consolidation.
For quick reference both Acids and Alkalis in 35th Amendment of IMDG Code is listed below

hi,I was told by a DG Profi that UN2829 Caproic Acid (185kg net in 1A1) cannot be loaded in one sea container with ANY (or nearly any) of Class 3 or Class 9 goods. Can you confirm??? Maybe reference to IMO paragraph???
UN 2829 is an ACID hence all goods which is required to be “Away from ” or “Separated from” Acids cannot be loaded with this UN Number
Further UN 2829 is Class 8, see segregation table ( http://shashikallada.com/segregation-table/segregation-table-imdg-code-36-12/ ) which other classes can be loaded with this.
Regards/Shashi
there also some harmless and Class 3 and 9 goods, UN 3082, 1993 and 3272, all PG 3, without restrictions in Column 16. And exactly this is the question: is only Column 16 of the IMO DG list is applicable (then no problem – all 4 UN Nr can go together), OR only goods from segreg.group 1 are allowed to be loaded in one sea container?
Class 3 & 9 shows x in segregation table against Class 8 and UN 3082, 1993, 3272 does not have any column 16 entry regarding segregation hence these UN Numbers can be loaded with your UN 2829.
