How Rice Grading Works in Pakistan: PSQCA Standards, Lab Reports, and What the Numbers Mean

Last month a buyer in Dubai sent me a lab report from another supplier and asked, "Sufyan, is 4.2% broken actually good?" I told him it depends on what he ordered. If the contract said 2% max, then no — that shipment failed. If it said 5% max, he got a fine parcel. He'd been trading rice for six years and still wasn't fully sure what the numbers meant.

Honestly, that's more common than you'd think.

Rice grading in Pakistan sits on a mix of PSQCA rules, buyer contract specs, and old trade custom that goes back decades in Lahore and Karachi's commodity markets. Once you understand how the three fit together, reading a Certificate of Analysis stops feeling like guesswork.

What PSQCA Actually Covers (and What It Doesn't)

PSQCA is the Pakistan Standards and Quality Control Authority. They set the baseline through PS:1666 for basmati and separate standards for non-basmati long grain, IRRI-6, IRRI-9, and PK-386. These Pakistan rice quality standards define minimum grain length, moisture ceiling, broken percentages, damaged kernels, chalky grains, foreign matter, and paddy count per kilo.

For Super Kernel basmati, PS:1666 typically requires a minimum average grain length of around 6.5mm before cooking, moisture at 14% max, and broken kernels capped depending on the grade you're declaring. For 1121 basmati, we're talking 8.2mm minimum average length — one of the longest grains in the world commercially traded.

But here's the thing PSQCA doesn't do. It doesn't force every exporter to grade every lot to the same tightness. PSQCA is the floor. Buyer contracts are the ceiling. If you order 1121 Sella with "1% broken max, 0.5% damaged max, 11% moisture," that's tighter than PSQCA and that becomes the working spec for that shipment.

So when someone asks about PSQCA rice standards, the real answer is — they set what Pakistani rice must be at minimum to legally export under a given grade name. Your contract sets what you actually get.

Reading a Lab Report Without Getting Fooled

A proper Certificate of Analysis from a Pakistani lab (SGS, Intertek, Bureau Veritas, or a PSQCA-approved local lab like the one at Rice Research Institute Kala Shah Kaku) will show you around 12 to 15 parameters. Let me walk through the ones that actually matter.

Broken percentage. This is measured by weight, not grain count. A grain becomes "broken" once it's less than 3/4 of the average whole kernel length for that variety. For 1121, that means anything under about 6.15mm counts as broken. Some suppliers use 2/3 as the cutoff instead of 3/4 — always check which method the lab used. It changes the number.

Moisture. 14% is the industry ceiling for safe long-haul shipping. I prefer 12.5 to 13% for containers going to Africa or Southeast Asia because monsoon transit humidity can push it up. Above 14.5% and you're inviting mold claims when the container opens in Lagos or Jakarta.

Damaged and discolored kernels. Damaged means heat-damaged, insect-damaged, or fungus-touched. Discolored includes yellow, black-tipped, or red-streaked grains. For premium Super Kernel exports we hold this under 1% combined. Cheap parallel-market rice can run 3-4% and buyers don't always notice until the cooked plate looks off.

Chalky grains. Chalkiness is that opaque white patch in the kernel. It's a milling and paddy-quality issue. Under 4% is normal for good basmati. Above 6% and the rice looks visually inferior even if it cooks fine.

Foreign matter. Stones, husk, weed seeds, other grains. Should be under 0.1% for any serious export. If your COA shows 0.5%, question the mill.

Average grain length and length after cooking. For 1121, we expect around 8.2-8.4mm raw and 18-22mm cooked. Elongation ratio matters more to Middle East buyers than most others — a Saudi buyer will reject a 1121 lot that only elongates to 15mm even if every other number is perfect.

Paddy count. Unhulled paddy grains per kilogram. Under 5 per kg for well-milled export rice. Under 2 for premium.

Where Rice Grading Pakistan Falls Apart in Practice

Here's what I got wrong when I started. I used to trust the mill's in-house lab report and forward it to buyers. Then a container of PK-386 got held at Jebel Ali because the third-party lab found 6.8% broken against a 5% contract. The mill's report had said 4.3%.

The mill wasn't lying exactly. They'd tested a sample from the top of the lot. The bottom of the silo told a different story.

Now we do three-point sampling — top, middle, bottom of every lot before sealing containers — and we run the COA through an independent lab even when the buyer doesn't require one. It costs us roughly $180 to $340 per container depending on the parameter list. Compared to a rejection at destination port, that's nothing.

The other thing that trips buyers up is variety authentication. A COA can say "1121 Basmati" and the grains can still be blended with cheaper long-grain that looks similar visually. DNA testing (called PCR variety confirmation) is available through SGS Karachi and takes about 5-7 working days. If you're buying premium 1121 or Super Kernel and paying premium prices, ask for it on every third or fourth shipment. Just as a check.

A Small Note on Grade Names

Pakistani trade uses grade names that don't always match what you'd expect. "Super Kernel" is a variety, not a quality grade. "1121" is a variety. "Sella" means parboiled. "Steam" means steamed (not the same as sella). "White" means raw milled. Then within each of those, you'll see "Grade A," "Creamy Sella," "Golden Sella," "1% broken," "2% broken," "5% broken" — and these describe the milling grade, not the underlying variety.

So "1121 Golden Sella 2% broken" tells you variety (1121), processing (parboiled with golden color), and milling spec (2% max broken). Three separate pieces of information stacked into one name.

Once you read the grade name like that, the COA starts to make sense as verification of each claim rather than one blob of numbers.

And if a supplier can't clearly break down which part of the name refers to what — that's usually a sign to slow down before you wire the deposit.
