The standards for cold countries are very strict, like the EU and the ASTM standards, but these actually apply for tropical countries?
In Sri Lanka as a tropic country follows ASTM strandard which is regulated and accepted by Sri Lanka Stanadarad Institute. However, currently no biofuels are using in Sri Lanka.
In the case of Cuba, as you know, there is no standard at all. Each country or region should develop or select one standard to be implemented. The selection of the ASTM 6751 or EN 14214 is not possible in our context, If finally, we decide to produce biodiesel for generalization, we have to deal with the development of a national standard, adequate to the technology for its use, the lab tech for its quality control, the transportation technologies to be used but the blending range.
A milestone!!!
Maximum limit of Monoglycerides in Biodiesel (B100) in India is 0.8% (mass/mass). Indian is a tropical country. You can browse the reference in the following link:

@Mohammad, but Tey say... Emami Agrotech produces biodiesel that meets the Indian Standard IS 15607-2016 and European Standard EN-14214. This, may be means that they are in accordance with cold country's standards? Maybe this's due to fact that the export this biodiesel to cold countries.
Is there any experience of using biodiesel having high monogliceryde content in tropical countries?
There is technique available to reduce Monoglycerides contents in B100 biodiesel. You can browse my article in the following link:
https://www.researchgate.net/publication/270460742_Monoglycerides_reduction_in_rapeseed_oil_transesterification_for_production_of_high_quality_biodiesel
Monoglycerides course problem in cold weather condition. It should not be that much problematic in tropical countries. Even though the standard is strenghent, lillte high Monoglycerides contents may be rational in tropical countries.
Hope, this will help.

I agreed with you Dr. Mohammad Shahidul Islam, but if monogliceryde wouldn't represent a problem concerning flowability in tropical countries, maybe at the same time will not produce other issues affecting properties like viscosity, for example, that may reduce its quality as fuels as happens with the original vegetable oils. What do you think?
I agree with you, Luis Beltran Ramos. Transesterification of vegetable oil reduces its viscosity by 10 fold in its product, biodiesel. And Monoglycerides contents are also very low in biodiesel (
