Quality Control
An overview of KMIZEOLITE's quality control process.
Quality Control — A Guide to KMIZEOLITE's Certifications, Technical Data, and Review Criteria
Because zeolite is a natural mineral-based material, in real-world use the quality control system and document verification can matter more than the product name alone. This is especially true when responsible procurement is required—such as corporate supply, public procurement review, repeat sourcing, or industrial application—where the origin, physical property data, certification information, and availability of technical documentation must be verified systematically. This page provides a detailed overview of KMIZEOLITE's quality control foundation, certification status, and review procedures.
Why Quality Control Matters
Zeolite has an extremely broad range of applications. As the field changes—water treatment, agriculture, livestock, deodorization, pozzolan, living environment, and more—the quality points that need to be checked change as well.
| Application | Key Quality Checkpoints |
|---|---|
| Filtration | Particle size stability, hardness (4.0–5.0 Mohs), swelling index (Nil) |
| Agriculture | CEC (1.6–2.0 meq/g), soil suitability, organic certification (OMRI) |
| Livestock | FDA GRAS compliance, feed additive limit (2% or less), OMRI |
| Construction | Pozzolanic properties (ASTM C618), property consistency, particle size (100 mesh) |
| Environmental Remediation | CEC, ion-exchange selectivity, chemical composition data |
| Consumer / Household | Safety certification, California Prop 65 compliance |
Therefore, good quality control does not simply mean "it is clean." Rather, it means a state in which the data appropriate to the intended use can be verified and supplied consistently.

| EC No. | 215-283-8 | European chemical substance registration number |
Feed Additive Regulation Details
When considering feed additive use in the livestock sector, the following regulations must be reviewed.
- FDA: Zeolite is recognized as GRAS, but is permitted only for anti-caking purposes in feed.
- Maximum addition rate: 2% or less of the total feed formulation.
- OMRI: Allowed as an organic livestock feed ingredient (Livestock Feed Ingredient).
These regulations are U.S. standards. For domestic application, the Korean Feed Management Act and related notices must be reviewed separately.

The suitability and specifications for each particle size can be found on the Products page.
The 5-Step Quality Verification KMIZEOLITE Recommends
Before actual adoption, it is best to review in the following order.
Step 1. Verify Origin and Mine
First, confirm which region the raw material was produced in and whether the mine-based information is clear. KMIZEOLITE is produced in Amargosa Valley, Nevada, USA, and its mine information is publicly disclosed. Details can be found on the KMI Mine and Origin page.
Step 2. Verify the Product Data Sheet (PDS/TDS)
Confirm that key physical properties—such as purity, CEC, particle-size form, pH stability, and hardness—are clearly stated. Zeolite without a data sheet is difficult to verify for quality. On the Technical Data (TDS) page, you can review data for each KMI product.
Step 3. Review Application Suitability
Review whether the specification matches the intended purpose—water treatment, agriculture, livestock, construction, and so on. Even zeolite of the same purity can have different suitable uses depending on particle size.
Step 4. Verify Certification and Registration Information
Check the relevant certification or registration information according to the required market and use. For organic-related uses, check OMRI; for feed-related uses, FDA GRAS; and for safety-related uses, Prop 65 and TSCA.
Step 5. Sample Testing and On-Site Review
Because conditions can vary greatly in actual processes and environments, it is advisable to perform sample testing or small-scale verification before considering full application, where possible. Samples can be requested through KMIZEOLITE via the sample request page.
Important Distinctions on This Quality Control Page
This page is not a warranty page implying that the product is "equally suitable for all uses." Rather, it is a page that explains which materials should be verified to enable a reliable judgment. In particular, the following points should be clearly distinguished.
- Certification or registration information may be interpreted differently by use.
- Industrial, agricultural, livestock, and consumer uses may each have different application standards.
- Actual performance may vary depending on the target substance and process conditions.
- Overseas certification standards and domestic regulations need to be verified separately.
- Before adoption, it is advisable to re-check the latest materials.
KMIZEOLITE's Quality Communication Principles
When introducing zeolite, KMIZEOLITE places importance on the following principles.
- Guidance based on materials with verifiable sources: Based on KMI's public PDS/TDS.
- Explanations that are not exaggerated by use: Maintaining a "supplementary material" perspective.
- Explanations centered on key figures such as purity and CEC: Data over sentiment.
- Review centered on physical properties rather than product name: Judging by specification, not by name.
- Recommending advance review through samples and technical data: Adoption after on-site verification.
This approach is especially important for B2B, supply contracts, long-term sourcing, and public-institution requirements. KMIZEOLITE supports corporate and institutional customers in making decisions based on reliable technical data and certification materials when they review zeolite.
Notice
The certification and registration information stated on this page is based on KMIZEOLITE's public materials, and certification validity periods and detailed conditions are subject to change. In particular, the OMRI certification has an expiration date (2027.03.01), so its current status must be verified separately. Compliance with relevant domestic regulations (the Feed Management Act, the Fertilizer Management Act, building-material standards, etc.) must be reviewed separately by use, and KMIZEOLITE does not provide any legal guarantee in this regard.
