Dangerous goodsIMDG by sea, IATA DGR by air

Pharmaceutical products and raw materials for medicines are overseen by the DNM, which issues sanitary registrations and import authorisations. Controlled precursors need separate permits held by the importer. MARN covers environmental aspects of chemical handling. Customs clearance follows Central American (SIECA) rules, and dangerous goods must be packed and declared under IMDG or IATA. As the economy uses the US dollar, invoicing in USD avoids currency conversion. Confirm the DNM status of each raw material with your broker before booking freight.

Questions

Impurity Reference Standards for El Salvador

Can Zemixal deliver impurity reference standards to El Salvador?
Yes. We ship by sea to Acajutla and La Unión, 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 El Salvador?
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 DNM (Dirección Nacional de Medicamentos) is agreed with you at quote stage.
How long does delivery to El Salvador take?
Allow 35–50 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.
