Tariff classification and duty concession for 13 inputs used in lithium-ion cell manufacturing, exemption allowed with IGCR, 2022 compliance

An advance ruling was sought on (i) tariff classification of 13 goods proposed for use in lithium-ion cell manufacture and (ii) eligibility for concessional duty under the relevant customs exemption entry covering "parts, sub-parts, inputs or raw materials" for lithium-ion cells. Applying the use-based description and chapter-neutral scope of the entry, and construing the exemption purposively without defeating its object, the authority held the goods were functionally indispensable and directly integrable into the production line; consequently, exemption benefit was allowed for all 13 items, subject to strict compliance with the IGCR, 2022 condition and actual end-use. It further ruled that specified adhesive tapes fall under 3919 10 00; polyether-modified polysiloxane under 3910 00 90; POLYSOL LB-150J under 3903 90 90; and PVDF under 3904 69 90.

1. ISSUES PRESENTED AND CONSIDERED

(i) Whether the advance ruling application was maintainable and could be decided on merits under the applicable framework.

(ii) What is the correct tariff classification, applying the General Rules for Interpretation and relevant Chapter/Section Notes, for the thirteen proposed imported items used in the manufacture of lithium-ion cells (including self-adhesive plastic tapes; a polyether-modified polysiloxane; a styrene-acrylate copolymer emulsion; PVDF; an acrylate copolymer solution; lithium/sodium carboxymethylcellulose; and styrene-butadiene rubber latex).

(iii) Whether, upon such classification, the thirteen items qualify for concessional Basic Customs Duty under the use-based exemption entry (Serial No. 314 of the substituted notification), subject to compliance with the IGCR, 2022 procedure and actual end-use in manufacture of lithium-ion cells falling under tariff item 8507 60 00.

2. ISSUE-WISE DETAILED ANALYSIS

A. Maintainability/validity of the advance ruling application

Legal framework: The Court/Authority examined the application with reference to the Customs Act, 1962 and the CAAR Regulations, 2021 as the governing framework for entertaining and deciding the request.

Interpretation and reasoning: On review of the application, jurisdictional comments, hearing record, and additional submissions, the Authority found the application "valid" within the statutory and regulatory framework and proceeded to determine classification on the basis of the record.

Conclusion: The application was held maintainable/valid and was admitted for decision on classification and exemption eligibility.

B. Classification of the thirteen imported items

Legal framework: The Authority applied the General Rules for Interpretation, particularly GRI 1 (classification by the terms of headings read with relevant Section/Chapter Notes), and considered relevant chapter notes/explanatory notes where used in its reasoning (including Note 6 to Chapter 39 for "primary forms").

Interpretation and reasoning: (1) For the six tapes, the Authority accepted that they are self-adhesive flat shapes of plastics, imported in rolls of width not exceeding 20 cm, and pressure-sensitive; therefore, they fall within heading 3919 and specifically tariff item 3919 10 00. (2) For polyether-modified polysiloxane, on the product description showing a silicon-oxygen backbone characteristic of silicones, the Authority preferred heading 3910 ("silicones in primary forms") over heading 3907 and classified it under 3910 00 90. (3) For POLYSOL LB-150J, described as styrene-acrylate copolymer emulsion used for adhesive applications, the Authority classified it under 3903 90 90. (4) For PVDF, the Authority found that the tariff item 3904 69 10 is designated for poly(vinyl fluoride), and treated PVDF as falling under the residual fluoropolymers sub-entry, thus classifying under 3904 69 90. (5) For the ethylpyrrolidone-acrylate copolymer NMP solution, treated as an acrylic polymer in primary form (solution), classification was fixed under 3906 90 90. (6) For lithium and sodium carboxymethylcellulose, being carboxymethylcellulose salts, classification was fixed under 3912 31 00. (7) For styrene-butadiene copolymer (SBR) latex, it was accepted as synthetic rubber latex in primary form and classified under 4002 11 00.

Conclusions (tariff items determined): (a) Golden PO tape, Blue hot melt tape, Bottom/top tape, Green tape, Double faced adhesive tape, Black acrylic tape: 3919 10 00. (b) Polyether-modified polysiloxane: 3910 00 90. (c) POLYSOL LB-150J: 3903 90 90. (d) PVDF: 3904 69 90. (e) Ethylpyrrolidone-acrylate copolymer NMP solution: 3906 90 90. (f) Lithium carboxymethylcellulose and sodium carboxymethylcellulose: 3912 31 00. (g) SBR latex: 4002 11 00.

C. Eligibility to concessional Basic Customs Duty under the use-based exemption entry (Serial No. 314), subject to IGCR, 2022

Legal framework: The Authority examined the operative exemption entry (Serial No. 314 in the substituted notification) providing NIL BCD for "parts, sub-parts, inputs or raw materials for use in the manufacture of Lithium-ion cells" falling under tariff item 8507 60 00, subject to Condition No. 3 requiring compliance with the IGCR, 2022 procedure and actual end-use.

Interpretation and reasoning: The Authority treated the exemption as chapter-neutral ("goods of any chapter") and use-based, focusing on whether the thirteen items are directly integrable in the lithium-ion cell production line and functionally serve as parts/inputs/raw materials for such manufacture. It found each item's described role (mechanical stability tapes; electrolyte additive; adhesive application resin; binder materials; slurry additives; dispersion stabiliser/binder) to be within the exemption's use-based description. The Authority held the exemption available, but expressly conditioned it on strict compliance with IGCR, 2022 and actual end-use in manufacture of lithium-ion cells under 8507 60 00.

Conclusion: All thirteen items were held eligible for the exemption benefit under Serial No. 314, subject to compliance with IGCR, 2022 procedure and actual end-use in manufacture of lithium-ion cells falling under tariff item 8507 60 00.
