Customer returns: judging a dried-out tub that came back

The box arrives on the counter with a note saying the substrate was dry on arrival and the animal would not settle. Inside, the tub is a 20 cm cube, the floor is a hard crust, the lid has six vent holes, and the dispatch label is dated nineteen days ago. Somewhere between those two facts is the answer, and it is not always the customer’s fault or yours.

Returns on live-animal substrate are awkward because the evidence degrades. A tub that was correctly hydrated at dispatch can be bone dry on return for reasons that have nothing to do with the product, and a tub that left too wet can look perfect after a week in a dry room. Judging them requires a routine, not a judgement call.

Why a dried tub is hard to judge

Water leaves a tub through the lid, and the rate depends on the room it sat in, not on the day it was packed. A tub that leaves at 85 percent and sits in a room at 30 percent with a radiator nearby will be at 50 percent in five days, which is a property of the room. The same tub in a cool bathroom would still be at 80.

So the question is never simply whether it is dry. It is whether the floor had enough reservoir to survive a normal week in a normal room, and whether the customer’s setup was one the product could reasonably serve. Both of those can be established from the tub itself, if you know what to look at.

Four checks before you decide

Weigh the tub as received. Compare it with the dispatch weight if you record one, which you should. The difference is the water that left, and 60 grams from a 20 cm cube over nineteen days is unremarkable. Two hundred grams is a different story and points at a lid that was never sealed or a tub that was packed too wet and lost free water early.

Then look at the crust. A floor that dried slowly has a uniform, slightly crumbly surface and shrinks away from the glass by a millimetre or two. A floor that dried fast has a hard shell with cracks and a still-damp centre, because the surface set before the water could move. The second pattern is what you see when a tub is left open or under a lamp.

Then check the lid. Six vent holes in a 20 cm cube is a lot of exchange for a product sold as humidity-retentive, and if that is what you shipped, the return is legitimate. If the lid has been drilled by the customer, it is not.

Then check the date and the species. A tub dispatched on a Friday and returned on a Monday is a different case from one returned after three weeks, and a species that needs 90 percent is a different case from one that needs 60. Both facts change what a fair outcome looks like.

• Weight difference against dispatch record
• Crust pattern: uniform shrink or hard shell with damp centre
• Lid condition: original vents, added holes, missing seals
• Elapsed time and species requirement

What the pattern tells you

After fifty returns you stop looking at individual tubs and start looking at clusters. If returns cluster around one lid type, the product is wrong. If they cluster around one shipping route, the transit is wrong. If they cluster around one customer type, usually first-time keepers in small tubs, the instructions are wrong and no amount of replacement stock will fix it.

The counterintuitive finding from our own records: the tubs most likely to come back were not the driest ones. They were the ones shipped at the highest moisture, because the free water condensed in transit, the surface looked wet on arrival, and the customer concluded the product was soggy and left the lid off to dry it out.

A rule you can apply at the counter

Replace without argument when the tub is under ten days old, the lid is original, and the floor has lost more than a third of its dispatch weight. Credit when the pattern is ambiguous and the customer is a repeat buyer, because the relationship is worth more than the tub. Decline politely when the lid has been modified or the tub is more than three weeks old, and offer a discounted replacement instead.

Write those three lines down and give them to whoever works the counter. Consistency matters more than the individual call, and a customer who gets the same answer twice stops arguing. For the moisture behaviour that underpins the whole policy, the humidity control guide is the document to point customers at when the return is really a setup problem.

Start recording dispatch weights this week, even if it is a kitchen scale and a marker. In three months you will be able to answer these questions with a number instead of an opinion.
