Customs movements can stop when open goods use all available guarantee capacity. A valid permit creates no extra room. Higher shipment volumes and longer storage can keep capacity tied up and delay the next transit movement.
Why this matters
A continuous guarantee avoids separate security for qualifying customs transactions. Its reference amount must cover customs debt that goods under the procedure may create. Higher values, longer storage, or new tariff classifications can raise that exposure. Open transit movements use capacity until discharge. The reference amount differs from the security provided. A reduction or waiver may lower the security required, but not the reference amount. Excess security can tie up bank room for stock, payroll, or supplier invoices.
Example
A wholesaler normally clears imported goods within ten days. A new distribution contract extends that period to three weeks, while shipment values rise. More goods sit under the customs procedure at once. Capacity is used sooner and released later, even though the permit has not changed. Finance still treats the guarantee as a fixed annual bank item. The logistics manager finds the shortfall when a new transit movement cannot start.
XTROVERSO tips
- Track open exposure. Compare the customs system with your internal ledger. Check which movements remain open and how much guarantee capacity is available.
- Review changes in goods flow. Flag higher volumes, longer storage, new suppliers, changed values, and different commodity codes. Each can change customs exposure.
- Keep the two figures separate. Calculate the full reference amount first. Then review the security percentage, reduction, or waiver that may apply.
- Use the right calculation for each permit. Transit, warehousing, temporary storage, and periodic declarations use different calculations. Keep the supporting calculation in each permit file.
- Give one person ownership. Assign one manager to connect operations, customs, and finance. Report permit changes and higher security needs to Customs and the bank before goods are delayed.
