Trade understanding governs excise classification of maplitho paper, and grammage alone does not decide the tariff entry.

Maplitho paper of 140 GSM to 179 GSM was treated as printing and writing paper under Item 17(1) rather than other kinds of paper under Item 17(2), because grammage was not a tariff-based demarcating criterion and trade understanding, supported by notices, technical material, invoices and affidavits, showed the product was recognised as printing and writing paper. The Department's material did not displace that evidence, and in a taxing statute the burden remained on the Department to prove the rival charging entry. Prior self-classification by the assessee did not create estoppel in tax matters, so the contrary demand could not be sustained.

Issues: Whether maplitho paper of grammage 140 GSM to 179 GSM was classifiable as printing and writing paper under Item 17(1) of the First Schedule to the Central Excises and Salt Act, 1944 or as other kinds of paper under Item 17(2).

Analysis: The relevant tariff entry did not prescribe grammage as a demarcating criterion between printing and writing paper and other papers, and grammage alone was not determinative of classification. The respondent produced trade notices, technical communications, invoices and affidavits showing that maplitho paper was understood in trade and industry as printing and writing paper. The departmental material relied upon, including undisclosed trade enquiry letters, did not rebut that evidence; on the contrary, some of it supported the respondent's case. In a taxing statute, the burden lay on the Department to establish that the goods fell within the charging entry, and that burden was not discharged. Prior classification by the assessee did not create any estoppel in matters of taxation.

Conclusion: The paper was held to be classifiable as printing and writing paper under Item 17(1), not under Item 17(2), and the demand based on the contrary classification could not be sustained in favour of the assessee.

Final Conclusion: The review notice was vacated and the Department's appeal failed on the classification issue, leaving the respondent entitled to the benefit of Item 17(1).

Ratio Decidendi: In excise classification, the relevant test is trade and commercial understanding supported by evidence, and where the Department fails to discharge the burden of proving applicability of the rival taxing entry, the assessee's classification must prevail.
