That's wonderful and I'm sure we're all very pleased you can come on here and shout about how your buying power gets you the bottom prices. This is very obvious and easily discoverable in any sphere of large scale commerce and we wish you good luck in continuing your father's business.
When I am brining in a big order of stuff those around me, amateur and professional alike, get a chance to share in the purchase, until the load is fully booked. Hence there are a vast number now of these frames especially in service around the land at very fair prices. Only yesterday someone came to me and bought 400 of the deep frames from Romania. I do not believe in keeping the cake to myself and it makes me cringe seeing the prices you guys have to pay. So long as you are able to organise yourselves you will ALL be able to share in the benefits of major not for profit purchasing that will be a 'down the line' function of the co-operative that is building the sterilising plant.
I have heard wax carries disease so assume the NZ stuff has the UK stamp of approval.
The UK not much interested, and the purchase from NZ was strongly approved of in official circles as it was from an EFB free country. If you know of a disease in their wax please tell what it is. NZ is a far healthier bee country than ours. The last consignment was 6 tonnes of milled foundation of various sizes, and almost half of that was for other people who were delighted with the quality and price.
What you MAY be referring to was an impurity that was present in some NZ wax samples. Nowadays every wax batch there has to have an analysis done on it and a certificate of conformity issued before it can go for export. Much NZ wax is exported in bulk, and a lot of it comes to the UK. Much of it (and Australian btw) ends up in premium wax sold here.
Most of the cheaper grade waxes contain wax from China and Africa.
Having seen bulk consignments of wax from several countries I can assure you that the UK product is actually pretty nondescript and inconsistent (even my own) and I have no issues about buying the product from these premium countries.
