Factual and Procedural Background

The appellant-assessee manufactures “dimethicone.” The Assistant Collector of Central Excise classified the product under Tariff Item 3910.00 (silicones in primary forms). On appeal, the Collector (Appeals) reclassified it under Tariff Item 3003.20 (medicaments). The Revenue challenged that decision, and the Customs, Excise and Gold (Control) Appellate Tribunal (“the Tribunal”) reversed the Collector (Appeals) and reinstated classification under 3910.00. The present appeals before the Supreme Court contest the Tribunal’s judgment dated 27-8-1997.

Legal Issues Presented

  1. Whether “dimethicone” is classifiable as a medicament under Tariff Item 3003.20 of Chapter 30 of the Central Excise Tariff.
  2. Alternatively, whether it is classifiable as a silicone in primary form under Tariff Item 3910.00 of Chapter 39.

Arguments of the Parties

Appellant’s Arguments

  • Dimethicone satisfies Chapter Note 2(i)(a) to Chapter 30 because it is allegedly a product composed of “two or more constituents” mixed or compounded together for therapeutic or prophylactic use.
  • Consequently, it ought to be treated as a medicament falling under Tariff Item 3003.20, attracting “Nil” duty.
  • The Tribunal mis-recorded that the appellants did not deny dimethicone is a silicone in primary form; that observation should not stand.

Respondent Revenue’s Arguments

  • The product is an unmixed silicone in primary form as evidenced by the appellant’s own classification list.
  • As a silicone in primary form, dimethicone falls squarely within Tariff Item 3910.00 of Chapter 39 and cannot be re-classified as a medicament.
  • The prior Supreme Court decision in Hico Products Ltd. v. Collector of Central Excise conclusively determined that dimethicone is a silicone in primary form.

Table of Precedents Cited

Precedent Rule or Principle Cited For Application by the Court
Hico Products Ltd. v. Collector of Central Excise (1994) 4 SCC 578 Held that dimethicone is a “silicone in primary form.” The Supreme Court treated this factual finding as binding despite changes in tariff headings, confirming that dimethicone remains a silicone in primary form.
Pragati Computers Pvt. Ltd. v. Collector of Customs (2000) 10 SCC 150 Reiterates that the Tribunal is the final fact-finding authority and Supreme Court interference is limited to perversity. Cited to justify deference to the Tribunal’s factual finding that dimethicone is an unmixed product.
Reliance Silicon (I) (P) Ltd. v. CCE (1997) 1 SCC 215 Same principle: limited Supreme Court interference with Tribunal’s factual conclusions. Reinforced reliance on the Tribunal’s findings.
Asian Paints India Ltd. v. Collector of Central Excise (1988) 2 SCC 470 Same principle of deference to Tribunal’s fact-finding. Cited alongside other cases to support non-interference.
Collector of Customs v. Swastic Woollens (P) Ltd. 1988 Supp SCC 796 Same principle regarding finality of Tribunal’s factual determinations. Cited to support the Court’s decision not to disturb the Tribunal’s conclusions.

Court's Reasoning and Analysis

1. The Court first noted that Hico Products conclusively classified dimethicone as a silicone in primary form. Although tariff headings have since changed, that factual characterisation remains binding.

2. By virtue of Note 1(c) to Chapter 38, goods that qualify as “medicaments” under Chapter 30 are excluded from Chapter 39. Therefore, the dispositive question becomes whether dimethicone can be considered a medicament under Chapter Note 2(i) to Chapter 30.

3. The Tribunal found—and the Supreme Court emphasised—that the appellants’ own classification list describes dimethicone as an unmixed product. Under Note 2(i)(a), a medicament must consist of two or more constituents that have been mixed or compounded together. Because dimethicone is unmixed, it falls outside that definition.

4. The Court rejected the argument that the chemical process of hydrolysis (involving multiple chemicals) converts an unmixed end-product into a “mixed” medicament for tariff purposes.

5. Invoking a consistent line of authority (Pragati Computers, Reliance Silicon, Asian Paints, Swastic Woollens), the Court reiterated that it will not disturb factual findings of the Tribunal absent perversity, which was not demonstrated here.

Holding and Implications

Appeals Dismissed. The product “dimethicone” is classifiable under Tariff Item 3910.00 as a silicone in primary form.

Implications: The appellant remains liable for duty applicable to silicones in primary form. The decision reinforces the Supreme Court’s reluctance to revisit factual determinations of the Tribunal and does not establish new substantive tariff law.

    Order

    1. These appeals are against the judgment of the Customs, Excise and Gold (Control) Appellate Tribunal (for short “the Tribunal”) dated 27-8-1997. The question for consideration is whether the product manufactured by the appellant-assessee, namely, dimethicone is classifiable under Tariff Item 3003.20 (as claimed by the appellant) or under Tariff Item 3910.00 (as claimed by the respondent Revenue). The Assistant Collector held that the product was classifiable under Tariff Item 3910.00 The Collector (Appeals) allowed the appeal and held that the product was classifiable under Tariff Item 3003.20 The Tribunal by the impugned judgment has reversed the order of the Collector (Appeals) and has held that the product is classifiable under Tariff Item 3910.00

    2. For consideration of the question, it is necessary to note the tariff items. They read as follows:

    4.1.1 “Heading No. Sub-Heading No. Description of goods 39.10 3910.00 Silicones in primary forms”

    4.1.2 Note 6 to Chapter 39
    “6. (a) In Headings 39.01 to 39.14, the expression ‘primary forms’ applies only to the following forms —
    (i) Liquids and pastes, including dispersions (emulsions and suspensions) and solutions;
    (ii) Blocks of irregular shape, lumps, powders (including moulding powders), granules, flakes and similar bulk forms.
    (b) Notwithstanding anything contained in Note 3 to this Chapter, Headings 39.01 to 39.14 shall also include primary forms obtained from conversion of another primary form, falling under the same heading, and such conversion shall amount to ‘manufacture’.”
    4.1.3 Heading 38.23 and Sub-Heading 3823.00

    “38.23 3823.00 Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included; residual products of the chemical or allied industries, not elsewhere specified or included” 20%

    4.1.4 Note 1 to Chapter 38
    “1. This chapter does not cover:
    (a)-(b) ***
    (c) Medicaments (Heading 30.03).”
    4.1.5 Heading 30.03 and Sub-Heading 3003.20

    “30.03 Medicaments (including veterinary medicaments) 3003.20 -Medicaments (other than patent or proprietary) other than those which are exclusively used in ayurvedic, unani, siddha, homoeopathic or bio-chemic systems Nil”

    4.1.6 Note 2(i) to Chapter 30
    “2. For the purposes of Heading 30.03:
    (i) ‘Medicaments’ means goods (other than foods or beverages such as dietetic, diabetic or fortified foods, tonic beverages) not falling within Heading 30.02 or 30.04 which are either—
    (a) products comprising two or more constituents which have been mixed or compounded together for therapeutic or prophylactic uses; or
    (b) unmixed products suitable for such uses put up in measured doses or in packings for retail sale or for use in hospitals.”

    3. At this stage, it must be mentioned that the question whether the product dimethicone is a silicone or not came up for consideration before this Court in Hico Products Ltd. v. CCE (1994) 4 SCC 578. This Court after considering the then tariff items came to the conclusion that it was a silicone and inter alia held as follows:

    “The products of the appellant as specifically classified in the lists and described as such separately are not noticed and classified as such in the pharmacopoeia as drugs by themselves or drugs intermediate. Rather the products of the appellant are found by expert opinion to be silicones in the primary form, of the grades specified. There is thus no basis herein to distinguish silicone as industrially used or medicinally used.”

    4. The Tribunal in the impugned judgment has held that the judgment of this Court was not applicable as it was based on different tariff items. Undoubtedly, the judgment was in respect of different tariff items. But the fact remains that this Court has given a categoric finding that this product is a “silicone in primary form”. This finding would therefore continue to be binding. Tariff items may change but it cannot now be urged that this product is not “silicone in primary form”. Of course even though this product is a “silicone in primary form” by virtue of Note 1 to Chapter 38, it would not be covered by Entry 39.10 if it is a “medicament”.

    5. The question therefore is whether it can be considered to be a medicament. The Tribunal, without the aid of Hico Products case (1994) 4 SCC 578 came to the conclusion that the product is a silicone in primary form. In doing so, it has recorded that “it is not denied that dimethicone BPC is otherwise a silicone in primary form”. It was submitted that this observation was not correct. It was submitted that it was always disputed that the product was a “silicone in primary form”. However, we find that there is no ground in the memo of appeal that this finding of the Tribunal has been wrongly recorded. Even otherwise, it is a settled law that if a court or tribunal records something then that has to be taken as correct unless the party gets the same clarified from that court or tribunal itself. As the appellants have not made any effort to get this position clarified from the Tribunal nor taken any ground in the memo of appeal it is not possible to accept this submission.

    6. The submission on behalf of the appellants is that their product is a medicament inasmuch as it falls under Note 2(i)(a) of Chapter 30. It is claimed that it is a product comprising of two or more constituents which have been mixed or compounded together. The Tribunal has not accepted this. Before we consider reasoning of the Tribunal it must be noted that the Assistant Collector had given a categoric finding that dimethicone BPC was an unmixed product and that it was a silicone in primary form. The Collector (Appeals) has not dealt with the finding that it is an unmixed product. The Collector (Appeals) has proceeded on the footing that as the product has therapeutic or prophylactic use it would be a medicament. Of course, the Collector (Appeals) notes that the product has two or more constituents but has not noticed that the appellants themselves have shown this product to be an unmixed product in the classification list filed by them.

    7. The Tribunal which is a final fact-finding authority has considered both these opinions. It has observed that the appellants themselves filed the classification list showing this product to be an unmixed product. If the product is an unmixed product, merely because a process of hydrolysis of two or more chemicals is involved, the product would not fall within Chapter Note 2(i)(a) of Chapter 30. With this finding of the Tribunal we are in full agreement.

    8. Even otherwise, the law on the subject is clear. The Tribunal is the final fact-finding authority. Unless it is shown that there is something perverse in its finding, this Court would not interfere. No authority is required for this purpose. But as a large number of authorities are cited, we refer to them: Pragati Computers (P) Ltd. v. Collector of Customs (2000) 10 SCC 150, Reliance Silicon (I) (P) Ltd. v. CCE (1997) 1 SCC 215, Asian Paints India Ltd. v. CCE (1988) 2 SCC 470 and Collector of Customs v. Swastic Woollens (P) Ltd. 1988 Supp SCC 796

    9. For the above reason, we see no reason to interfere with the impugned judgment. The appeals stand dismissed. There will be no order as to costs.
