The quality of a macadamia container is decided long before it's loaded — in the orchard, the drying shed and the grading line. When you're vetting a macadamia NIS supplier, the right questions surface those decisions early. Here are twelve to ask before you place an order.
Origin & traceability
1. Are you the grower, or are you aggregating supply? A single-origin grower-exporter can trace every lot to an orchard block. At Umkondo Estate we grow, process and export from one 80-hectare farm.
2. Which cultivars do you grow? Variety drives nut size and kernel recovery. Beaumont (695) and the A-series (A4, A16) are proven high-recovery cultivars.
3. Can you give me the harvest date and lot for my container? Fresh-season nuts behave predictably; old stock doesn't.
Processing & quality control
4. How do you dry, and to what moisture? In-shell NIS should be dried to 8–10%. Controlled drying (we use PLC-managed driers with temperature monitoring) protects the kernel from cracking and mould.
5. How quickly do you dehusk after harvest? Husks must come off within about 24 hours or the kernel starts to deteriorate.
6. What kernel recovery should I expect, and is it tested? 30%+ is a strong benchmark; high-KR select grades can be lab-tested at 32%+.
7. What's your defect rate? Premium and large grades should sit under 2–3%.
Consistency & scale
8. Can you supply consistent grades container after container? Spec on paper is easy; repeatability across a season is the real test.
9. What volume can you commit to, and over what window? Match this to your processing schedule and counter-season needs.
Trade & compliance
10. Which Incoterms do you quote? A capable exporter offers EXW, FOB and CIF and can explain the trade-offs (see our buying guide).
11. What documentation is included? Phytosanitary certificate, certificate of origin, fumigation certificate, packing list, bill of lading, commercial invoice — and third-party inspection (SGS/Intertek) on request.
12. Will you support a trial container first? A confident supplier welcomes a trial before any volume commitment.
The short version
A good NIS supplier is transparent about origin, disciplined about drying and grading, and comfortable with scrutiny. Vague answers on any of the twelve above are a warning sign.
