Why Broken Kernels Change a Rice Bid
Broken rice kernels usually sell below head rice. The bid should say how that percentage is measured and paid.
Rice is traded as whole kernels and as pieces of kernels. Brokens are the pieces. They mill differently, they cook differently, and they usually bring a lower price than head rice, the share of kernels that stayed long enough to count as whole under the buyer's standard. A bid that quotes one number for paddy or for milled rice without saying how brokens are treated is an incomplete bid. Grading ideas that apply across grains, including damage, are outlined at https://goodsandgrain.trade/grain-grading-test-weight-damage. Rice adds this break-and-length question on top.
What breaks, and when
Kernels break in the field, in drying, and in the mill. Hot, fast drying and rough handling raise the share of pieces. Variety and the way the crop matured matter too. By the time milled rice is in a bag, the broken percentage is a fact about that lot. You will not talk it back into head rice. You can only describe it honestly and find the buyer who priced that description.
Paddy rice, which still wears the hull, hides some of this. The mill will reveal it. A paddy contract that ignores milling yield and brokens has postponed the argument until the mill, which is a costly place to meet it.
Why buyers care about the percentage
Head rice is what many table-rice buyers want to see on a plate. Brokens have uses, including processing and markets that accept a higher broken share at a lower price. Those uses are real. They are not the same bid. A seller who hears that brokens are still rice and concludes they should fetch the head-rice price is arguing with the product the buyer is trying to pack.
The allowed percentage belongs in the contract. So does the method: who samples, which sieve or classifier is used, and what happens above the cap. A discount per point and a rejection threshold are different deals. Know which one you signed.
Sampling is the whole argument
Brokens are not perfectly uniform in a sack or a tote. A handful from the top of a bagged lot can mislead in either direction. Piece-count shipments need the same honesty as a truck probe. How a probe is used on bulk grain is described at https://goodsandgrain.trade/probe-sampling-a-grain-truck. For bags, take pieces from several bags in the lot, not from the one that looks best, and mix them before the test.
If a mill certificate and a destination survey disagree, the contract should say which result governs. Silence is how both certificates become opening offers.
Drying and handling are where you still have a choice
Once the kernel is broken, the bid has already changed. The choices that still exist are earlier. Dry in steps the mill or the local advisor actually recommends for that rice, rather than in one harsh pass that buys speed and sells head rice. Move bags and totes without throwing them. None of this guarantees a milling yield. It avoids the losses that are plainly mechanical.
Identity matters if you have a variety known for milling quality. Mixing it with a poorer lot to fill an order averages the broken count in the wrong direction and can void the variety claim at the same time.
Read the bid as two products
Ask the buyer for the head-rice assumption inside the price and the schedule for brokens. Compare that net with a buyer who openly wants a higher broken share. Sometimes the second buyer is the better sale for the lot you have. Forcing a table-rice spec onto a high-broken lot produces rejections, not premiums.
Standards differ by market. This note does not quote a universal broken limit. Use the sheet attached to your sale.
Frequently asked questions
Are broken kernels just a cosmetic issue?
For some buyers they change the product, not only the look. The price gap is there because the uses differ.
Can careful drying raise head rice?
Gentler drying and handling can avoid breaks you would otherwise cause. They cannot repair kernels that are already broken.
Should paddy contracts mention brokens?
If payment depends on milling results, yes. Otherwise the broken count arrives as a surprise after the hulls come off.
