Injection
Injection is delivering presorted parcels directly into a carrier's facility (for example a USPS destination delivery unit) rather than having the carrier pick them up.
Why it matters for ecommerce brands
Postal injection through consolidators can lower costs for lightweight packages.
Common questions
- What does parcel injection mean?
- Injection means delivering packages directly into a carrier's network at a facility close to the destination, rather than handing them over at origin. Carriers price injected packages lower because they travel less within the carrier network.
