A word of counsel

The most frequent error on this tariff line is treating Legal Metrology approval as optional on the basis that these instruments are intended for in-plant industrial use rather than trade. Sections 19 and 20 of the Legal Metrology Act, 2009 apply to automatic gravimetric filling instruments regardless of end-use when the instruments are of a class specified in the Seventh Schedule; an unapproved instrument is liable to seizure and the importer faces monetary penalty under the Act.

Frequently asked

Does HSN 8423 30 00 require BIS certification?

No, no BIS Quality Control Order covers constant weight scales or hopper scales under this tariff line. Import is instead governed by the Legal Metrology Act, 2009 and the Legal Metrology (General) Rules, 2011, which require registration and product approval for automatic gravimetric filling and totalising hopper weighing instruments.

Which specific instruments under this HSN require Legal Metrology product approval?

Automatic gravimetric filling instruments and discontinuous totalising automatic weighing instruments (totalising hopper weights) require product approval under Rules 11 to 15 of the Seventh Schedule of the Legal Metrology (General) Rules, 2011, where applicable to the imported model.

What happens if the importer registration certificate is not uploaded in e-Sanchit at the time of bill of entry?

The customs proper officer will withhold out-of-charge until the certificate of registration of importer of weights and measures (document code 101lm1) is uploaded in e-Sanchit; continued non-upload exposes the consignment to detention and demurrage at the port.
