Unseasoned timber cracking

Sheesham shipped above 12% moisture splits when it meets central heating in the US or EU. The single largest claim category.

SeverityCRITICAL
MaterialSolid hardwood — sheesham, mango, acacia
Process stageTimber seasoning and kiln drying, before machining
SurfacesSix weeks to six months after delivery, in the first heating season.
Hairline crack running along the grain of a sheesham tabletop, with a steel rule beside it for scale. SPLIT 0.4MM

Why it happens

Kiln time is the first thing cut when an order is running late for a vessel date. The surface of a board reads dry on a pin meter long before the core does, so a batch can look ready and ship wet.

Wood then gives up that moisture wherever it lands. In a centrally heated home in a British or German winter, or an Arizona warehouse, it shrinks across the grain and the tabletop splits or the joint opens.

Because the failure happens weeks after delivery, it reaches you as a customer return rather than a shipping dispute — which is why it is the largest single claim family we log.

Write it into the order

How to specify against it

A defect you can name in the purchase order is a defect an inspector can fail the shipment on. One you only describe in an email is not.

  1. Put a number in the purchase order, not an adjective. "Properly seasoned" is a hope; "≤10% at pre-shipment inspection, pin meter, core reading" is a specification.
  2. Set the limit against the destination climate, not the factory’s. Our published shipping specifications run 6–8% for Canada, 7–9% for the USA, 8–10% for the UK, Germany and the UAE, and 9–11% for the Netherlands and Australia.
  3. Require the reading as a range across sampled pieces rather than one figure, so a single flattering board cannot represent the batch.
  4. Book a during-production visit as well as a pre-shipment inspection. Once the batch is packed, a moisture failure means unpacking and re-kilning against your vessel date.
