US based quality verification, MagVanta documentation, and traceability you can audit
What we specify, how every lot is tested, and what ships with it.
The premise
A certificate is only worth the testing behind it.
So we test again, independently, in the United States, on the lot you are buying.
In short
- Independent US laboratory testing on every pharmaceutical and supplement channel lot, and on any other lot on request.
- Release to sellable stock only on passing results.
- MagVanta certificate of analysis, lot-specific.
- Retained samples and lot traceability through despatch.
- Documented chain of custody on every lot, source to dock.
- Foreign Supplier Verification Program handling for food, supplement and feed channel material.
Process
How a lot becomes sellable inventory
-
Pre-shipment specification
Agreed in writing before production: assay, impurity limits, particle size, reactivity band and packaging.
-
Inbound sampling
Every inbound lot is sampled on arrival against a documented plan, and samples are retained, so a later question is answered against physical material.
-
Independent laboratory testing
Samples go to an independent US laboratory: assay, impurity profile, and the physical parameters that matter for the grade.
-
Release or hold
A lot reaches sellable stock only on passing results. Anything outside specification is held and resolved before it can reach you.
-
Lot-specific documentation
MagVanta issues the certificate of analysis for that lot, with the technical data sheet and safety data sheet alongside.
-
Traceability
Lot identity follows the material through receipt, storage, picking and despatch, so any bag traces back to its results and retained sample.
Laboratory partner, sampling plan and sample retention period are confirmed in the quality agreement for your account.
What the testing is for
Purity gets a grade through the door. Reactivity decides whether it works.
An assay tells you what is in the drum. It does not tell you how the material will behave once it is in your system. Two lots can both certify at 99% MgO and perform nothing alike, because reactivity is set by thermal history, by how hot and how long the ore was calcined, and not by the purity figure at all.
That is why a reactivity number is on every certificate we issue. It is measured as citric acid reactivity, in seconds to neutralize, and fewer seconds means a faster material.
- VHR
- 12 to 20 s
- HR
- 20 to 30 s
What it means where you are standing: a slow grade passes part way through a short residence system and leaves unreacted, so you feed more of it to reach the same endpoint. A faster grade reaches that endpoint with less material. This is the reason we test reactivity per lot rather than assay alone, and it is the reason the certificate describes how the material behaves rather than only what is in it.
Documentation
The document package
Four documents, all issued by MagVanta.
-
COA
Certificate of Analysis
Lot-specific, reporting what our US testing measured.
-
TDS
Technical Data Sheet
Chemistry, typical values, particle size, reactivity, packaging and handling.
-
SDS
Safety Data Sheet
GHS-aligned, 16 section, in the current US OSHA format.
-
Docs
Channel documentation
Allergen, non-GMO and continuing guaranty statements, on request.
Channel obligations
Food and feed channel obligations handled for you.
For material entering the food, dietary supplement, and animal feed channels, the food-channel verification obligations are handled on your behalf, including the supplier verification activities and records the program requires.
That program covers food. Material used as an antacid active ingredient is a drug ingredient and sits under the drug framework instead. Industrial grades sit outside both. Ask for the documentation that matches your channel.
Certifications
Certifications and quality systems.
MagVanta magnesium is manufactured under FDA-registered, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified quality, environmental, and safety systems, with HACCP food-safety and GMP+ feed-safety certification, and MOCRA-registered cosmetic-grade production for personal-care material.
Every lot is tested and released to the MagVanta specification in the United States and documented by MagVanta.
Digital traceability
Every lot, documented end to end.
Every lot carries a documentation record covering origin, processing and calcination, US test results and warehouse release. One auditable chain of custody, available on request. Per-lot digital verification is being rolled out, so a future lot will carry a scannable record of its own.
US compliance
Compliance handled before your price is quoted.
A food-channel verification program covers food, supplement and feed material, and TSCA requirements are met for every chemical supplied. The regulatory work behind that is carried before your price is quoted, not passed to you.
Regulatory notes
Regulatory notes
- MagVanta makes no health, treatment or nutritional claim for any material it supplies, and nothing we sell is FDA-approved. Where a material is destined for a regulated channel, the applicable framework follows your finished product: a dietary supplement is a food, an antacid active ingredient is a drug, and the obligations differ.
- Responsibility for the finished product, including its formulation, labelling and regulatory status, remains with the customer who makes it.
Ask for the quality agreement before you ask for the price.
We will share the specification, the documentation package and the verification approach for the grade you are evaluating, so your quality team can review it before commercial terms are on the table.
