Pharma compliance in Portugal

Authority	INFARMED / EMA
Seaports	Sines, Leixões, Lisbon
Airports	Lisbon (LIS), Porto (OPO)
Dangerous goods	IMDG by sea, IATA DGR by air

Portugal applies EU REACH and CLP. For substances imported at 1 tonne or more per year, the EU importer or an Only Representative for the Indian manufacturer must hold the registration. SDS and labels must be in Portuguese. Medicinal active substances need GMP compliance and an EU written confirmation, and INFARMED supervises authorised importers. Hazardous goods are packed and declared under IMDG or IATA DGR, and customs clearance requires the importer's EORI number.

Questions

Impurity Reference Standards for Portugal

Can Zemixal deliver impurity reference standards to Portugal?

Yes. We ship by sea to Sines and Leixões, 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 Portugal?

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 INFARMED / EMA is agreed with you at quote stage.

How long does delivery to Portugal take?

Allow 20–28 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.
