Some Common Confusion for UQC Code 

Since, there are so many concepts covered under GST alone, some taxpayers often get confused by UQC Code under the GST regime. For example, business organisations maintain several differences for a single measurement unit. Litres can be written and used in various forms such as L, Ltr, Litres, Litre, etc. and it might be accepted under other circumstances but exceptionally under the GST regime.

Use of other types of unit variations may cause an error. On furnishing any invoice details for goods and purchases, you must follow the Government’s offline tool-GSTR-1. This tool helps to know about the quantity details furnished using the UQC list of the GST portal. No other data which is kept and maintained by the organization is applicable or appropriate to use as a quantity under GST. 

Conclusion 

Unique Quantity Code or UQC is the code that helps to measure quantity under the standard portal of GST. This code ensures and maintains standard units of measurement that must be followed by any taxpayers who files the tax under GST. There are still many organisations who maintain their own records for quantifying the items with their own assuming units. However it is important to use the single quantity administration which is directed under the GST portal. 

Frequently Asked Questions 

1) How can one report the UQC under the GST portal?

2) How can one get the correct determination of UQC code?

For determining the correct UQC, you should follow the GST portal which mentions updated UQC code as per the government formulation. For example, Square Yards (SQY), Grams (GMS), Bundles (BDL), etc. are used in quantifying the material. 

3) What are the common challenges for UQC?

Some organizations still use their own data to simplify the measurement unit. This may be due to lack of awareness, training sessions or outdated systems.

4) What is invalid UQC Code in GST?
