# Practical do’s & don’ts for trading/ops (where write‑off issues often appear)

#### Do's

- Ensure<span> </span>**quantities**<span> </span>(B/L/manifest vs CHED) are realistic and aligned with tolerance policy. Customs systems are known to have not implemented these tolerances in their system. To raise with Vemobin/NCO-NCW industry associations.
- In contracts, explicitly define:
    - who files the CHED/GGB,
    - who pays sampling/inspection/storage,
    - what happens under partial release or rejection.
- If splitting is expected: design the<span> </span>**administrative chain**<span> </span>upfront (single consignee vs multiple; warehousing; resale before/after customs clearance).

####   


#### **Don’ts**

- Don’t try to “fix” the CHED/GGB only upon arrival; for SPS goods<span> </span>**pre‑notification timing**<span> </span>is often strict.
- Don’t assume you can freely reallocate volumes once part of a consignment has been released/“written off”.
