National Technical Regulation QCVN 07A:2020/BCT on the Quality of Industrial Ammonia
This technical regulation stipulates technical requirements, test methods, and management rules for ammonia in aqueous solution (HS code: 28142000) (ammonia content between 10 and 35%) for industrial use that is manufactured in, imported to, traded in, or transported within Vietnam. However, highly pure ammonia and ammonia for food processing purpose is excluded from the scope of this regulation.
Technical requirements for industrial ammonia are stipulated as below:
|
No. |
Item |
Quality level |
Test method |
|
| 1 | Content of ammonia (wt%) | 10–20 | 20–35 | – Section 3.1.2 of TCVN 2615:2008 |
| 2 | Content of Iron (Fe) (%) | ≤ 0.0001 | ≤ 0.0002 | – TCVN 2618:1993
– Section 3.2.3 of ASTM E291-18 |
| 3 | Content of residue after evaporation (%) | ≤ 0.003 | ≤ 0.005 | – Section 3.3.2 of TCVN 4560:1988 |
Before placing any regulated ammonia on the market, it is mandated to declare the conformity to this technical regulation. The declaration must be made pursuant to the Circular 36/2019/TT-BCT.
