Low dust
Low Dust Cat Litter, Measured at ≤ 1%
Our tofu, cassava, pine and corn lines are produced to ≤ 1% dust, and a batch test report covering dust is available with your quotation. This page covers where dust comes from, how to check a shipment on arrival, and which specification choices move the number.
Where dust in cat litter actually comes from
Every plant-based granule starts as a dry mix of flour and fiber. Our tofu and pine lines both carry pea fiber, corn starch, corn flour, calcium carbonate, sodium alginate and guar gum; the cassava line is cassava starch with corn starch; the corn line uses corn stalk where the pine line uses pine wood. In a starch-and-fiber granule, the particles in that dry mix that do not bind into the finished granule are what a buyer later sees as dust.
Granule form decides how much dust a bag can produce in handling. A cylindrical pellet pressed to 1.5 / 2 / 3 mm, which is the tofu lines, has few edges to break off. A crushed granule at 0.5–3 mm, which covers the cassava, pine and corn lines, carries a larger proportion of small particles by construction. That is why we quote the figure per line rather than as one company number. Thefine-granule cassava cat litter page carries that line's own figures.
Dust is also made after the granule is made. Conveying, screening and filling all generate fines, and a bag abrades against its neighbours for weeks in a container. A granule that is clean at the filler can still arrive with fines settled at the bottom of the bag, because vibration sorts small particles downward over a long sea freight. This is normal for the material, and it is why sampling only from the top of a bag tells you very little.
Our dust figure: ≤ 1%, line by line
We publish one dust figure, ≤ 1%, and it applies to the tofu, cassava, pine and corn lines. On the tofu line it is written on the product page and on the spec sheet as ≤ 1% dust (99% dust-free), which is the same number in two forms: at most one percent of the product is dust, and at least ninety-nine percent is granule. Both readings come from the same batch test report.
The lines differ in form and granule size, not in the dust figure. All five tofu SKUs share one pellet at 1.5 / 2 / 3 mm and one dust level; what changes between them is the scent or the activated carbon, not the granule. Seeunscented tofu cat litter for the base SKU page.
| Line (SKU page) | Granule form | Granule size | Dust |
|---|---|---|---|
| Unscented tofu | cylindrical pellet | 1.5 / 2 / 3 mm | ≤ 1% |
| Green tea tofu | cylindrical pellet | 1.5 / 2 / 3 mm | ≤ 1% |
| Peach tofu | cylindrical pellet | 1.5 / 2 / 3 mm | ≤ 1% |
| Lavender tofu | cylindrical pellet | 1.5 / 2 / 3 mm | ≤ 1% |
| Activated-carbon tofu | cylindrical pellet | 1.5 / 2 / 3 mm | ≤ 1% |
| Cassava | crushed granule | 0.5–3 mm | ≤ 1% (SGS third-party verified) |
| Pine | crushed granule | 0.5–3 mm | ≤ 1% |
| Corn | crushed granule | 0.5–3 mm | ≤ 1% |
| Tofu–cassava blend | blended granule | 0.5–3 mm | ≤ 1% at base |
| Custom | to your specification | to your specification | developed to your target |
The scented and carbon versions of the same pellet each have their own page: green tea tofu cat litter and activated-carbon tofu cat litter.
Two rows in that table need a note. On the tofu–cassava blend the figure is ≤ 1% at the blend's base, and we do not carry a relative improvement figure onto this page: a percentage against another line is only useful to a buyer once the test method and the baseline behind it are stated too, and we would rather leave it out than publish a comparison you cannot verify. On the custom line there is no fixed number at all. Dust is developed to the target you set, and it is confirmed in the sample report before you commit a container.
The cassava line is the one in this range that carries SGS third-party verification of its dust level, alongside our batch test report. If you are comparing suppliers, that distinction is worth checking line by line, because "low dust" on a competitor's page often has no stated method behind it at all.
How to check dust when the container arrives
Start before the bag is opened. Match the batch code printed on the bag to the batch code on the test report you were sent. A report that cannot be matched to the bag in your hand describes a different production run, and whatever figure it carries does not apply to what you are standing in front of.
Then sample two places rather than one: from the top of the bag, and from the bottom after the bag has traveled. Pour each sample onto a clean dark tray in daylight, holding the bag close to the surface rather than pouring from standing height, and watch what leaves the granule. A plume that stays in the air and drifts is the thing to record. A light settling of fines on the tray is normal in any plant-based granule and is not the same observation.
If your QA sieves a sample, ask us for the screen size the batch report was produced on before you compare figures with another supplier. Two suppliers both quoting ≤ 1% against different screens are not quoting the same number, and the difference can be larger than the gap between the products.
Repeat the check on a second pallet. A specification is a range across production runs, not a promise about one bag, and lot-to-lot variation is what the range exists to absorb. One bag proves one bag.
Dust, clumping and tracking: how they connect
Fines are not a defect to be driven to zero. They are part of what gives a clump its initial grip, and a granule with none of them takes longer to draw liquid in. The trade-off is real, and ≤ 1% is the level we hold it at: enough fine material for the clump our lines are built for, which forms in around 3 seconds, and little enough that the bag does not behave like a dust source when it is poured.
Tracking is a different question from dust, and we do not publish a tracking figure, because what a cat carries out of the box depends on granule size, on the mat, on how the cat leaves the box and on how deep the litter sits, more than it depends on the litter alone. Within our range the crushed-granule lines - cassava, pine and corn - all run 0.5–3 mm, and the tofu lines run a 1.5 / 2 / 3 mm cylindrical pellet. If tracking is the complaint you are solving, the larger, heavier granule is the usual starting point, and pellet diameter is the first variable to test.
What dust and tracking share is the fine fraction. Fines that stay in the bag are invisible; the same fines on a paw, or on the floor around the box, are what a customer notices and writes about. That is why the checks in the previous section matter more than a single headline number. A buyer who samples top and bottom, and tests a granule size against their own box and mat, is measuring the thing their customer will actually see.
What the ≤ 1% figure covers, and what it does not
It covers the granule as produced, per batch, as recorded on the batch test report. That is the number we can put a document behind, and it is the number a purchase specification should be written against.
It does not cover what happens after the bag is opened. Once litter is poured repeatedly, dug through daily and stored in a humid bathroom, the fine fraction in the box is a function of use, not of the bag you bought. It also does not describe a different batch, a different granule size, or a bag that has been stored damp.
It is a specification, not a certificate, and it is not a health claim. Where a dust figure goes into a tender or a retail listing, ask which laboratory produced it, on which batch and by what method. That question is worth putting to every supplier, including us.
Where a destination market asks for documentation on the material, the SDS and the batch test report are the two documents to request with the quotation, and we supply them per product rather than as a generic company file.
Customization and packing: how dust control moves with your spec
Granule size is the first lever, and it is yours to set. The tofu lines run a 1.5 / 2 / 3 mm cylindrical pellet, and cassava, pine and corn all run 0.5–3 mm. On a custom line the granule and the dust target are both built to your specification rather than picked from that list, which is why the custom row in the table carries no fixed figure. Parameters you can set are listed undercustom granule size and specification
The second lever is the pack. Pack format and print are open to your artwork on every line, and a printed retail pack carries a higher minimum than a bulk bag because of film and print setup. We confirm the exact figure with your quote rather than quoting a range you then have to re-check. Pack formats by destination market are on thepack formats and labeling by market page.
The third lever is the target itself. If a retail listing needs a figure tighter than ≤ 1%, tell us the number and the granule size together, because the two move each other. We will confirm what the specification can hold before the sample is made, so that the number on your pack is the number on the report.
MOQ is 10 tons for a single cat-litter SKU, about one 20GP, and because mixed-container loading is standard here, that minimum can travel alongside other litter or pee-pad lines in the same container. If dust performance is the reason you are switching a SKU, say so when you brief us and the sample will be built to that test rather than to a generic specification.
