J-STD-033C, Handling, Packing, Shipping and Use of Moisture/Re flow and/or Process Sensitive Components, provides guidance for certain electronic components that, to date, had not been covered. Those include parts classified per J-STD-075, Classification of Non-IC Electronic Components for Assembly Processes.
The C revision also contains a correction made to the desiccant desiccant /des·ic·cant/ (des´i-kant)

The new standard was developed by IPC and JEDEC. It provides surface mount device manufacturers and users with standardized methods for handling, packing, shipping and use of moisture/reflow-sensitive SMDs. These methods help avoid damage from moisture absorption and exposure to solder reflow temperatures that can result in yield and reliability degradation. - CD
