Supplying impurity reference standards to Uzbekistan

Sea freight reaches Poti, Georgia (via Caspian/rail) and Aktau, Kazakhstan (via rail) in about 40–55 days port to port. Urgent or small lots fly to Tashkent (TAS) in 3–5 days. Import compliance for this category sits with Center for Safety of Pharmaceutical Products (Ministry of Health), and we prepare the COA, SDS and commercial documents your broker needs. Common grades for this division are Impurity reference standard with characterisation data, Secondary / working standard, Stable-isotope labelled standard and Nitrosamine (NDSRI) standard.

Dangerous goods	IMDG by sea, IATA DGR by air

Uzbekistan requires conformity assessment for many imported products, and chemicals commonly need Uzbek or Russian labelling and SDS, arranged by the importer. Some hazardous substances need additional permits. Pharmaceutical substances are overseen by the Center for Safety of Pharmaceutical Products under the Ministry of Health. As a double-landlocked country, Uzbekistan receives sea cargo by rail from Caspian, Georgian or Chinese gateways, so SMGS rail documents are part of the shipment file. Dangerous goods follow IMDG or IATA.

Questions

Impurity Reference Standards for Uzbekistan

Can Zemixal deliver impurity reference standards to Uzbekistan?

Yes. We ship by sea to Poti, Georgia (via Caspian/rail) and Aktau, Kazakhstan (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 Uzbekistan?

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 Center for Safety of Pharmaceutical Products (Ministry of Health) is agreed with you at quote stage.

How long does delivery to Uzbekistan take?

Allow 40–55 days for ocean transit or 3–5 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.
