What to verify before a delivery date is committed
A committed date should be the output of four checks, in this order, each producing a written answer. The order matters because each check can invalidate the one before it, and doing them in sequence avoids committing a date that a later check removes.
Check one: the route and the filing party. Confirm in writing which territory the goods move from, which territory they enter, and which party files the declaration under which identification number. If the answer is that the supplier handles it as standard, ask for the standard to be described: which documents they issue, who files, and what they need from the buyer. This check produces the shape of the process and therefore the realistic length of it.
Check two: the classification and the rate. Obtain the intended tariff code per line and confirm nothing in the physical goods changes it. Where an item contains a battery, a liquid or an electronic component, treat that as a question with its own answer rather than a detail inside a general answer. This check produces the duty component of the landed cost and, in most cases, the largest single reason a quoted landed figure and an invoiced one differ.
Check three: the document pack. Ask for the pack by name and get a sample or a description of each document: the commercial invoice showing goods value and freight separately, the packing list, the transport document, the origin evidence, and any conformity document the category requires. This check produces the confirmation that nothing will be assembled on the day of shipment by someone who has never seen the order.
Check four: the contingency. Ask what happens if the authority asks a question the file does not answer, who responds, and in what timeframe, and ask what the fallback is if the answer is that the goods wait. This is the check most buyers skip and the one that determines whether a schedule risk is a single afternoon or a calendar event. A supplier who can describe the fallback is describing a process they have used before, and that is worth more than a confident statement that nothing will go wrong.
When all four checks produce written answers, a delivery window can be committed rather than hoped for. When any one produces a verbal answer, the honest position with internal stakeholders is a window with a note attached — which costs a little credibility once and saves considerably more than that on a loading dock.
