For API 13A Drilling Fluids, Bentonite must be selected by performance requirements, not only by product name.
Miningsun supplies export-ready sodium and calcium bentonite clay from China for international buyers who need stable quality, clear documentation and responsive quotation support. This guide explains what procurement teams usually ask before placing a trial order or full-container order.
Why specification matters
Bentonite for drilling fluids must deliver stable viscosity, yield and filtration performance under the selected drilling conditions. The correct Bentonite grade can improve performance, reduce processing risk and make procurement more predictable. The wrong grade can create handling, strength, viscosity, insulation or compatibility problems depending on the end use.
Buyers should connect the application requirement to a measurable specification such as chemistry, fineness, activity index, viscosity, bulk density or particle-size distribution.
What to request from the supplier
Ask for technical data before placing a purchase order. The supplier should be able to provide TDS, MSDS, COA, viscosity/yield data and third-party inspection when requested and explain which grade is normally used for API 13A Drilling Fluids.
- Relevant standard: API 13A, OCMA and civil engineering project specifications
- Available grades: API drilling grade, civil grade, foundry grade and GCL grade
- Packaging options: 25 kg bags, 50 kg bags, 1 MT jumbo bags or palletized export packaging
- Shipment from: Tianjin, Qingdao, Shanghai or Ningbo
- COA and sample approval before bulk shipment
Procurement checklist
Before buying, confirm the grade, documents, packaging, loading port, target delivery date and inspection requirements. For high-value or high-risk projects, request a pre-shipment inspection and keep a sealed reference sample from the approved batch.
Frequently Asked Questions
Is Bentonite suitable for API 13A Drilling Fluids?
Yes, when the grade, particle size and standard are matched to the application. Buyers should confirm test data before bulk ordering.
What should be checked before approval?
Check the relevant standard, COA, particle-size or chemistry data, sample performance and packaging condition.
Can Miningsun provide samples?
Samples are available for qualified buyers before full-container purchase.

API 13A bentonite checklist for drilling-fluid buyers
Drilling-fluid buyers should confirm performance data before comparing bentonite price per ton. API 13A-style bentonite discussions usually include viscosity, yield point or rheology targets, filtrate control, moisture, residue and packaging. Share the drilling application, required test method, destination port and trial quantity so the supplier can match the grade to the mud program rather than quoting a general industrial bentonite.
Specification points to confirm before quotation
| Item | What to ask the supplier | Why it matters |
|---|---|---|
| Drilling grade | API 13A-style test data and recent batch COA | Performance evidence helps screen suppliers before paying for samples or a trial load. |
| Fluid properties | Viscosity, yield point, filtrate, residue and hydration behavior | These values affect mud performance, field handling and approval by the drilling team. |
| Physical quality | Moisture, sand or residue content, mesh size and appearance | Physical consistency affects storage, mixing speed and usable yield. |
| Packing and documents | 25 kg bags, 1 MT jumbo bags, pallet option, COA, TDS and MSDS | Clear packing and document control reduce import and warehouse problems. |
Sample, MOQ and shipping notes
A practical first step is to test a representative sample using the same hydration time and lab method your drilling team will use for approval. Before shipping samples, confirm sample weight, courier cost, required labeling and whether the buyer needs material reserved from the same batch. For container quotations, send destination port, preferred packing, estimated monthly volume and whether the order is for stock, tender supply or a specific drilling project.
