Supplier Audit Checklist for Mod Orders — a Printable Checklist

Published 2026-07-13 · 6 min read · by the VapeWholesaleHub sourcing team

Mod has moved from a niche listing to a category that most vape retailers simply have to carry. That popularity brought a flood of near identical offers. This guide explains how to separate a repeatable supply chain from a lucky sample.

Turning Mod Into Repeats

Use your mod staff training time on the two questions customers actually ask. Anything more detailed gets forgotten by the second shift.

How Mod Fits the Assortment

Decide early whether mod is a traffic driver or a margin line in your store. The answer changes how you price it, where you place it and how hard you push it at the counter.

The Specification That Matters

Where possible, tie part of the mod payment to inspection against the written spec. It focuses attention on the numbers rather than on the relationship.

Getting Mod to Your Warehouse

Plan the mod customs paperwork at the same time as the order, not when the goods are on the water. A missing document costs more in demurrage than the entire freight saving from a cheap forwarder.

Split mod shipments across two sailings when the order is large enough. It costs slightly more but removes the risk of a single event wiping out a full quarter of stock.

Market Signals

The most durable mod lines over the last few years have been unglamorous and consistent. Novelty sells once; reliability sells every month.

Expect mod packaging requirements to keep tightening. Designs that leave room for additional labelling age better than tight layouts that need a full reprint to comply.

Practical Checklist

Frequently Asked Questions

Can I mix strengths in one order?

In most cases yes, as long as each strength meets the minimum run length. Mixed strength cartons are popular with retailers building their first display because they show the full ladder without over committing.

What is the usual minimum order for mod?

For a standard production run the minimum is normally one master carton per flavour, though mixed cartons can be arranged for a first order. If you are testing the line, ask about a sample pack first and treat the freight as part of your research budget.

Do you hold stock for regular customers?

For established programmes we can reserve production slots and, in some cases, hold finished mod stock against a forecast. It removes most of the lead time risk from a reorder and is worth discussing once volumes are stable.

Can I visit the production facility?

Yes, and we encourage it for larger programmes. Visits are most useful when you already have a draft specification, because you can then check the specific processes behind the numbers you care about.

What if a batch does not match the sample?

Keep the retained samples from the approval stage. If a delivered batch measurably differs, we compare against the retained set and resolve it against the production record. This is why we insist on sealed retained units from every run.

Next Step

Send us your current mod specification even if you are not planning to move suppliers. A second read of a document you use every month is usually worth the ten minutes.
