The PPA says Royal Mail's proposal that any mailed item more than 12mm thick should be classed as a packet and incur extra costs is too narrow a boundary and should be raised to 15mm.
This, the PPA argues would take into account three major elements to magazine delivery, inserts, supplements and promotional CDs or DVDs.
The PPA is also arguing that an intermediary price line should be introduced for any item which is more than 10mm think but whose surface varies in depth by between 5mm and 10mm.
Royal Mail launched its consultation into the plans to price mail by size rather than weight in April. The Direct Marketing Association has already spoken out against the move, arguing that while other countries such as Germany and Australia already take into account the size of mailings in their prices, it is not used as a key factor.
