2
Ensure customs clearance is obtained only after PESO approval is confirmed and all supporting documents are in order. Where PESO approval is pending but the importer has applied through the PESO online system, refer to the COVID-era exemption conditions under CBIC Instruction 12/2021-Cus for any outstanding consignments under that specific relief framework.

A word of counsel

The most common error on this tariff line is treating the COVID-era PESO inspection-exemption — which waived physical inspection of foreign manufacturing facilities for oxygen cylinders — as a permanent or general waiver of PESO import approval requirements. That exemption applied solely to medical oxygen cylinders imported for COVID relief activities and does not extend to standard gas generators or unrelated pressure vessels; the obligation to apply for and obtain PESO approval through the online system remains operative for all other consignments.
