Dangerous goods	IMDG by sea, IATA DGR by air

Tajikistan requires certificates of conformity for many imported goods, issued through Tajikstandard, and hazardous or precursor chemicals need permits held by the buyer. Medicines and APIs are supervised by the Ministry of Health and Social Protection of Population, which maintains a registry of approved products. Sea cargo reaches the country by rail through Uzbekistan and Kazakhstan from Chinese or Caspian gateways, so SMGS rail documents and transit papers are essential. Dangerous goods follow IMDG or IATA.

Questions

Impurity Reference Standards for Tajikistan

Can Zemixal deliver impurity reference standards to Tajikistan?

Yes. We ship by sea to Lianyungang, China (via 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 Tajikistan?

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 Service of State Supervision over Health and Social Protection (Ministry of Health and Social Protection) is agreed with you at quote stage.

How long does delivery to Tajikistan take?

Allow 45–60 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.
