Czech imports fall under EU REACH and CLP. Registration for substances at 1 tonne or more per year is held by the EU importer or an Only Representative, and SDS and labels must be in Czech. APIs need an EU written confirmation or equivalent GMP standing and must go to a SÚKL-authorised importer. Sea cargo can be cleared at Hamburg or Koper, or moved under transit with a T1 document and cleared at a Czech rail terminal, so agree the clearance point before booking.

Questions

Impurity Reference Standards for Czech Republic

Can Zemixal deliver impurity reference standards to Czech Republic?

Yes. We ship by sea to Hamburg (via rail) and Bremerhaven (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 Czech Republic?

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 SÚKL / EMA is agreed with you at quote stage.

How long does delivery to Czech Republic take?

Allow 28–36 days for ocean transit or 4–6 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.
