Pharma compliance in Mongolia
| Authority | Medicines and Medical Devices Regulatory Agency / Ministry of Health |
|---|---|
| Seaports | Tianjin (via rail to Ulaanbaatar), Vladivostok (via rail) |
| Airports | Ulaanbaatar Chinggis Khaan International (UBN) |
| Dangerous goods | IMDG by sea, IATA DGR by air |
Sea cargo is usually discharged at Tianjin and moves by rail through Erenhot and Zamyn-Uud, so Chinese transit formalities and rail dangerous goods rules apply on the way. Toxic and hazardous chemicals, including mining reagents such as cyanide, need permits from the Ministry of Environment under Mongolia's law on toxic and hazardous chemicals. Medicines and APIs require registration with the health authorities. Dangerous goods must meet IMDG or IATA rules, and APTA preference requires a certificate of origin.

Questions
Impurity Reference Standards for Mongolia
Can Zemixal deliver impurity reference standards to Mongolia?
Yes. We ship by sea to Tianjin (via rail to Ulaanbaatar) and Vladivostok (via rail), by air cargo or by express courier depending on quantity and urgency. Every lot carries a COA and a 16-section GHS SDS.
Which documents come with a impurity standards shipment to Mongolia?
Commercial invoice, packing list, certificate of analysis and SDS as standard, plus the bill of lading or air waybill and a certificate of origin. Anything specific to Medicines and Medical Devices Regulatory Agency / Ministry of Health is agreed with you at quote stage.
How long does delivery to Mongolia take?
Allow 30–45 days for ocean transit or 4–7 days by air, plus packing, export clearance and import clearance. The timeline on this page shows each stage.
How is the purity of an impurity standard determined?
Purity is usually assigned by HPLC area percentage, supported by structural confirmation from NMR and mass spectrometry. Where needed, water content, residual solvents or a mass balance approach are added. The methods used and the results for your lot are listed on the certificate of analysis that comes with the vial.
Can I use your impurity standards in place of official pharmacopoeial references?
Our standards are secondary or research materials, not official pharmacopoeial references. Many laboratories use them for method development, peak identification and routine testing, and keep official references for disputes or regulatory submissions where these are mandated. Your quality system and regulator decide which reference is acceptable for each test.
