What skill ID is used for combining in quest containers?

[Drawde]

Sorry to post ANOTHER question - however this is something I was wondering about whilst creating quest scripts. What is the tradeskill ID (or IDs) used for quest-related containers - the ones where you need to collect items/ingredients and combine them (e.g the containers used for making newbie quest armour material, or the boxes for beetle eyes etc.). If the skill ID is known, then it would be possible to add these "recipes" so these quests can be implemented.
