How to calculate dimensional weight for shipping
Carriers commonly bill the greater of physical and dimensional weight. Measuring the finished parcel prevents adjustments and damaged margins.
Operational answers about packaging, billable weight, carrier adjustments, tracking, customs, APIs and returns.
Carriers commonly bill the greater of physical and dimensional weight. Measuring the finished parcel prevents adjustments and damaged margins.
A weight adjustment is a later charge when the carrier network measures more than declared or detects another handling rule. It is not always just extra pounds.
Good packaging protects the product while controlling dimensional cost, scan reliability and evidence. The largest box is not necessarily the safest.
A created label does not mean the carrier has the parcel. The first diagnostic step is separating label creation from the first physical acceptance scan.
Cancelling a label is a request to the carrier, not deleting a PDF. The essential condition is that the tracking number has not been used.
Insurance does not replace proper packaging or guarantee automatic payment. Coverage, provable value, evidence and deadlines determine the claim.
Extended area is a carrier coverage classification. It can affect visit frequency, total price, service availability and delivery estimate.
For an international shipment, the label moves the parcel while documentation explains what is crossing. Vague descriptions and inconsistent values cause delays.
A useful API does more than return PDFs: it preserves identity, prevents duplicate purchases, tolerates partial failures and exposes reconcilable states.
The cheapest label can be the most expensive delivered order if it creates more delays, contacts, reships or adjustments.
A return does not end when the buyer prints a label. It must link to the order, be received and inspected, then close with inventory and financial decisions.
