What happens when a co-loader above you has not switched to eHBL and is still doing paper re-manifests?

The rule to reject an electronic house bill when the previous house bill is not on file was put into place during the voluntary period to address scenarios where not all freight forwarders involved in the consolidation were transmitting electronically. Due to the unpredictable nature of paper and electronic house bills, a decision was made that during the voluntary period all house bills in all tiers must be electronic, or the existing paper process would have to be used. This rule will be turned off when house bills become mandatory, at which time the system will accept the tier 2 house bill even if the previous is not yet on file. A ‘not matched’ response will be sent to the sender of the tier 2 house bill.
