Distribution test discussion guide

Purpose and output shape

The selector is a shortlisting aid for a packaging test conversation. You choose one distribution channel and enter the packaged-product weight in pounds. The tool returns two rows: Laboratory discussion starting point and Recorded weight. The first row is a protocol family or a routing instruction, not a final test plan. The second row repeats the entered weight with lb appended. Every result also carries the same handoff note: supply the complete distribution route, pack style, dimensions, fragility and acceptance criteria to the laboratory. Use the output to prepare questions, not to close the test decision.

Choosing the distribution channel

Channel is the only input that changes the starting point for five of the six options. Parcel is the only channel where weight can change the message. LTL freight returns Discuss ISTA 3B. Unitized truckload returns Discuss ISTA 3E. Amazon own-container and Amazon overbox both begin with Amazon, so both return Confirm current Amazon program and applicable ISTA 6-Amazon procedure. Retail distribution returns Obtain retailer protocol before selecting a test. Choose the channel that describes how the packaged product actually moves. If a shipment crosses modes, run the selector for each relevant leg and take both starting points to the laboratory.

Entering packaged-product weight

Enter the packaged-product weight in pounds. The field accepts a positive number and uses the value as entered; the output appends lb. Do not enter the product weight alone if the packaged weight is what the laboratory needs. Do not convert to kilograms for this field. Weight is recorded for every channel, but in this tool it only branches the Parcel result. For LTL freight, unitized truckload, Amazon own-container, Amazon overbox and retail distribution, a different weight changes the Recorded weight row but not the Laboratory discussion starting point row. A weight change on a non-parcel channel is a record change, not a protocol change.

Reading the parcel screen

For Parcel, the selector applies a 150 lb screen tied to the published 3A scope. At 150 lb or below, the starting point is Discuss ISTA 3A. Above 150 lb, the starting point becomes Parcel 3A weight scope exceeded; ask the laboratory. The boundary is inclusive at 150 lb: 150 returns the 3A discussion, while 151 returns the exceeded message. Treat this as a screening rule only. The method states that the 150 lb published 3A scope is applied only as a screen, and channel programs may impose different tests. A parcel result does not establish that 3A is the final test type, nor does it certify the package.

Worked parcel cases

Case one uses channel Parcel and weight 30. The output rows are Laboratory discussion starting point: Discuss ISTA 3A and Recorded weight: 30 lb. The handoff note asks for the complete distribution route, pack style, dimensions, fragility and acceptance criteria. This is the starting scenario: a 30 lb parcel suggests a 3A discussion, not a completed test selection.

Case two keeps channel Parcel and changes weight from 30 to 151 lb. The output rows are Laboratory discussion starting point: Parcel 3A weight scope exceeded; ask the laboratory and Recorded weight: 151 lb. The handoff note is unchanged. This 121 lb increase crosses the screen; 151 lb is one pound above the inclusive 150 lb boundary. The message therefore changes from a 3A discussion to a scope-exceeded instruction. That is why the weight field matters for Parcel and why the exact threshold should be respected when you compare runs.

Amazon and retail routes

Amazon own-container and Amazon overbox are separate channel choices, but both match the Amazon branch. The selector does not choose between them or infer a pack style. It returns Confirm current Amazon program and applicable ISTA 6-Amazon procedure for either choice. Retail distribution returns Obtain retailer protocol before selecting a test. In both cases the weight is still recorded, but the routing instruction is the important output. Confirm the current program and the retailer protocol with the responsible party before asking a laboratory to quote or schedule work. The selector does not replace those program documents.

Limits and laboratory handoff

The tool does not select a final test type or certify a package. Retailer requirements, revisions and laboratory scope govern. The output is a discussion starting point, so bring the recorded channel and weight plus the complete distribution route, pack style, dimensions, fragility and acceptance criteria to the laboratory. Ask the laboratory to confirm the current procedure and any program-specific additions. If the channel is mixed or the route includes more than one mode, discuss each leg rather than forcing one channel to represent the whole journey. Keep the output with your test request so the starting point and the recorded weight are visible together.
