Shenzhen and Pearl River programmes often ship electronics modules with metal hardware in humid subtropical air. Teams either skip corrosion free volume or force anti-static film on pure metal kits that never needed ESD control. Both mistakes show up as field claims. A global manufacturer specifies multimetal VCI film for bare metal free volume after dry clean, anti-static VCI film when ESD rules apply, VCI stretch for unitised cartons, and aluminium barrier free volume with sized desiccant when multi-week ocean sealed life applies after South China port exit.
Shanghai is plant, port and ocean three-stage Yangtze export. Shenzhen stays ESD-plus-corrosion decision tree under Pearl River humidity so China pages do not become doorway twins.
| Kit reality | Primary free volume | Do not |
|---|---|---|
| Bare metal only | Multimetal VCI bag closed after dry clean | Force anti-static without ESD need |
| Electronics + metal, ESD rules apply | Anti-static VCI free volume | Ordinary poly that fails both jobs |
| Multi-day humid plant store | Sealed free volume from day one | Open trays until packing day |
| Multi-week ocean leg | Barrier free volume + desiccant with VCI | Film-only hope through container rain |

With VCI and desiccant for multi-week export sealed life.
View Full SpecsShanghai is written as three-stage Yangtze export failure plant, port and ocean. Shenzhen is Pearl River electronics and mixed metal export where ESD and corrosion decisions stack on the same kit.
Wrong ESD versus corrosion grade choice, open free volume under humid subtropical air, and film-only ocean designs on multi-week legs.
When ESD rules apply to electronics or modules in the kit. Multimetal VCI alone is not an ESD system.
When the kit is bare metal only with no ESD requirement. Do not force anti-static on pure metal packs without need.
When sealed life includes multi-week ocean humidity after South China port exit.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO certificates and a method note covering ESD decision and humidity hold.
No. BENZ is a global protective packaging manufacturer.
