No, Australia does not officially use "MR" (Moisture Resistant) as a plywood grade the way India and some other countries do.
Australia follows AS/NZS standards, and moisture resistance is indicated primarily by the bond type rather than an “MR” label.
| Bond Type | Standard | Water Resistance | Typical Use |
|---|---|---|---|
| A-Bond | AS/NZS 2269, 2271, 2272 | High (waterproof resin) | Exterior, marine, structural – long-term durability |
| B-Bond | AS/NZS 2271 | Moderate (moisture resistant) | Interior use with occasional moisture exposure |
Labels should also include
-
Manufacturer name or trademark
-
Stress grade (F8, F11, etc. for structural ply)
-
Glue type (A-bond for moisture resistance)
Physical Inspection Tips
-
Surface should be uniform, clean and free of core gaps (especially for Marine Ply) and knots.
-
Edges should not display signs of irregular layering and delamination.
-
Should lie flat and not show warping or bowing.
Watch for Red Flags
-
No Australian Standard markings or unclear labelling
-
Very cheap price compared to market average
-
Rough finish or weak bonding between layers
