Industrial buyers should identify the required Bentonite Powder profile before requesting a quotation. The supplied reference includes separate OCMA and API 13A requirement tables, and each profile uses different test parameters.
What the OCMA profile measures
The supplied OCMA table covers slurry yield, fluid loss, moisture content, wet residue on a 200-mesh screen and dry screen analysis. The stated yield is 16 m³/MT minimum for a 15 cP apparent-viscosity bentonite and distilled-water slurry. Fluid loss is 15 ml maximum for the stated test slurry.
Moisture content is listed at 10% maximum, wet residue on a 200-mesh screen at 2.5% maximum and dry screen analysis at 98% minimum. Buyers should compare the wording and sieve reference with their approved purchase specification before accepting an offer.
What the API 13A profile measures
The supplied API 13A table lists a 600 rpm viscometer dial reading of 30 minimum, a YP/PV ratio of 3 maximum, filtrate volume of 15 ml maximum and residue greater than 75 µm of 4% by weight maximum.
Why the profiles should not be mixed
The two tables do not contain identical properties. A procurement team should therefore avoid requesting “standard bentonite” without naming the required profile. The correct RFQ should attach the approved limits and specify how the offered lot will be reviewed.
Bulk packing and delivery planning
Kasbonex Global’s current declared packing basis is a 1.5-ton jumbo bag. The buyer should state total tonnage, delivery schedule, destination and preferred Incoterm, and confirm that the receiving site has suitable unloading and storage arrangements.

Frequently asked questions
Can the supplier choose the profile for the buyer?
The required profile should come from the buyer’s project or approved procurement specification.
Is the supplied table enough for order acceptance?
It is a reference for the enquiry. Final acceptance should use the agreed specification, lot documentation and any inspection terms stated in the purchase agreement.
