Debugging TSS Rejections: Common Failure Modes and Fixes

Read the Rejection First

Every TSS rejection points at a data problem. Treat it as a failing test, not a bureaucratic setback. The message will name a field. Start there.

Common Failure Modes

Description too vague. Fix: rewrite against the five-question standard and store the compliant version in the product master.

Commodity code invalid or wrong digit count. Fix: reverify against the current tariff and set the digit count by goods category.

Weight mismatch. Fix: confirm gross mass > net mass and both match the packing list.

Value mismatch. Fix: sum item values and reconcile to the invoice total; check currency.

Party mismatch. Fix: standardise identifiers and store one canonical spelling per party.

Preference claim without evidence. Fix: remove the claim or attach the evidence.

The TSS goods description standard covers the description fix in the most detail.

Root Cause, Not Line Fix

Fixing the line clears the shipment. Fixing the source stops the pattern. Push every rejection back to the record it came from.

Turn rejections into structural fixes, not one-off patches. Watch a demo.
