Seaports	Douala, Kribi
Airports	Douala (DLA), Yaoundé Nsimalen (NSI)
Dangerous goods	IMDG by sea, IATA DGR by air

Sea imports generally need an electronic cargo tracking note (BESC/ECTN), and declarations are lodged through the national single window. Some goods may also be subject to pre-shipment inspection or conformity checks, so confirm requirements with the importer before booking. Pharmaceutical ingredients are overseen by the pharmacy directorate (DPML) of the Ministry of Public Health. Hazardous chemicals may require authorisation from MINEPDED, the environment ministry. Documents are usually in French. Dangerous goods follow IMDG or IATA rules.

Questions

Impurity Reference Standards for Cameroon

Can Zemixal deliver impurity reference standards to Cameroon?

Yes. We ship by sea to Douala and Kribi, 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 Cameroon?

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 Ministry of Public Health – DPML is agreed with you at quote stage.

How long does delivery to Cameroon take?

Allow 28–38 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.
