Authority	DINAVISA (Dirección Nacional de Vigilancia Sanitaria)
Seaports	Montevideo, Uruguay (barge transhipment), Buenos Aires, Argentina (barge transhipment), Villeta / Asunción river terminals
Airports	Asunción Silvio Pettirossi (ASU)
Dangerous goods	IMDG by sea, IATA DGR by air

APIs and medicines need DINAVISA registration or an import authorisation before dispatch. Precursor chemicals are tightly controlled by SENAD, the national anti-drug secretariat, and the importer must be registered and hold a prior permit for each shipment. Environmental matters fall under MADES. For barge or road delivery, ask for a through bill of lading or ensure transit documents cover the leg from Montevideo, Buenos Aires or Paranaguá. Dangerous goods follow IMDG or IATA rules, and river and road carriers may add their own limits. An India–MERCOSUR PTA certificate of origin supports preferential duty on eligible goods.

Questions

Impurity Reference Standards for Paraguay

Can Zemixal deliver impurity reference standards to Paraguay?

Yes. We ship by sea to Montevideo, Uruguay (barge transhipment) and Buenos Aires, Argentina (barge transhipment), 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 Paraguay?

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 DINAVISA (Dirección Nacional de Vigilancia Sanitaria) is agreed with you at quote stage.

How long does delivery to Paraguay take?

Allow 30–45 days for ocean transit or 5–8 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.
