Most "product failure" complaints we investigate turn out to be storage failure: the additive left the factory fine and died in the warehouse. Tropical storage is a process, not a shelf.
Steps
- Control the microclimate. Target under 30°C and under 65% RH where possible. No direct sun on bags, 10 cm off the floor on pallets, 30 cm from exterior walls.
- Keep packaging integrity. Foil liners exist for a reason. Reseal opened bags tightly the same day; split large bags into smaller sealed lots if usage is slow.
- Rotate strictly FIFO. Label receiving dates; first in, first out. Check remaining shelf life on arrival — VS3965 18 months, VSW5 12 months, VS382 540 days from production, not from your receipt.
- Separate aggressive neighbors. Store additives away from choline chloride, acids and hygroscopic minerals which pull moisture and catalyze degradation.
- Audit monthly. Smell and visual check of open lots; slight color change in VS382 is normal, caking or off-odor is not — quarantine and contact your supplier.
Common mistakes
- Storing on the floor against a sun-heated wall — the two worst positions combined
- Buying a year of stock for a three-month usage rate in a humid climate
- Judging by the bag exterior — always inspect the inner liner seal
