How to Brief a Factory on Mod — Real Numbers Only

Published 2026-05-30 · 7 min read · by the VapeWholesaleHub sourcing team

Buyers often ask us to explain why two mod samples that look identical behave differently after a month. The answer is almost always tolerance control, and it is more interesting than it sounds.

Getting Mod to Your Warehouse

Carton dimensions for mod are a design decision, not a packing afterthought. A few centimetres on the master carton can change how many units fit a pallet, and that repeats on every order.

What to Fix Before Approving Mod

A written mod specification should be short enough to read in a minute and precise enough to argue about. If a factory cannot confirm a number in writing, assume the number is whatever is cheapest that week.

Inspection Before Dispatch

Most defects in mod are not dramatic. They are loose tolerances, a slightly thin seal, a mouthpiece that clicks. Left alone they turn into leak complaints, which are the single most common reason a retailer drops a line.

How Mod Fits the Assortment

A tight mod range with deep availability usually outsells a wide range with thin stock. Customers who find their line in stock come back; customers who are told to wait do not.

Category data for mod is noisier than it looks. Promotions, weather and local competition all move weekly numbers, so read three months at a time rather than reacting to a single week.

Trends Worth Watching

The mod category is consolidating around suppliers who can document what they ship. Buyers who built that requirement into their process early are now finding it much easier to scale.

Practical Checklist

Frequently Asked Questions

What does a sample pack usually include?

A typical mod sample pack covers the strengths or variants you are most likely to list, packed so you can evaluate them side by side. Tell us which lines you are considering and we will match the pack to that rather than sending a generic selection.

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.

How are price changes handled on repeat orders?

{K} pricing is reviewed against input costs and volume rather than adjusted casually. Any change is confirmed in writing before the next order is scheduled, with the reason stated so you can judge it yourself.

How do you handle a short shipment?

Cartons are counted and weighed before dispatch and the figures are shared with you. If something is short on arrival, the packing record and the carrier documentation are both available, which keeps the claim straightforward.

Next Step

If you take one thing from this page, take the retained sample habit. It costs a few units per batch and it is the difference between a disagreement and a decision.
