Stage-I tapioca processing residue classified as animal-feed residue under 2303 1000; not exempt under N/N.02/2017-CT(Rate), GST and registration required

AAR held the applicant's product is a processing residue from Stage-I tapioca starch manufacture, not cassava flour or starch, and is classifiable as residue used in animal feed under 2303 1000. Cassava starch itself falls under 1108 (GST 12%) and sago under 1903 (GST 5%). The residue has market value and is therefore not waste, so the exemption in N/N.02/2017-CT(Rate) for tariff item 1106 does not apply. The supply attracts GST and the supplier must register and discharge applicable tax.

1. ISSUES PRESENTED AND CONSIDERED

1. Whether the product described as "Tapioca Flour" (dried/crushed remnants of manioc/cassava roots) is classifiable under Chapter Heading 1106 (flour of roots/tubers) or under Chapter 23 (residues and waste from the food industries), specifically sub-heading 2303 1000 as "Residues of starch manufacture and similar residues".

2. Whether the exemption under Notification No. 02/2017-CT(Rate) (entry for tariff item 1106) applies to the product if so classified, including the relevance of "pre-packed and labelled"/brand conditions.

3. Whether the product is a "residue", "by-product" or "waste" for purposes of classification and taxation; the legal and factual tests distinguishing those concepts and their tariff consequences.

4. Consequent determination of liability to pay GST and the requirement for registration under Section 22 of the GST Act given the correct classification.

2. ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Classification: 1106 (casava flour) v. 2303 (residues of starch manufacture)

Legal framework: Classification must follow the Harmonised System (HS) adopted in the GST Tariff; headings relevant include 1106 (Flour, meal and powder of roots and tubers of heading 0714 - manioc/cassava) and 2303 (Residues of starch manufacture and similar residues). Notifications and tariff notes determining rates depend on correct HSN classification.

Precedent treatment: No judicial precedents were cited in the ruling; determination is driven by statutory tariff descriptions, tariff usage and certified manufacturing processes submitted by the parties.

Interpretation and reasoning: The Court examined certified manufacturing processes of Stage-I (starch/sago manufacture) and Stage-II (manufacture of product sold to traders). Casava flour under 1106 is produced by grinding whole peeled/dried roots into a coarse flour that retains protein, fat and fibre and is a primary product of simple cleaning/grinding/drying. Casava starch (1108) is a purified carbohydrate extracted as "milk" and processed to a fine white starch for sago and food use. The product in question is the fibrous leftover (thippi/kappi) produced during Stage-I starch extraction and subsequently dried, ground and sold by Stage-II manufacturers; it is generated incidentally to starch manufacture and serves primarily as animal feed.

Ratio vs. obiter: Ratio - classification rests on the factual finding that the product is the residue/by-product of a starch extraction process rather than the primary flour product described by 1106; accordingly the product falls under 2303. Obiter - general observations about global changes from earlier VAT/State classifications to GST tariff adoption and remarks about trade practice are ancillary.

Conclusion: The product is classifiable under Chapter sub-heading 2303 1000 ("Residues of starch manufacture and similar residues"), not under 1106.

Issue 2 - Applicability of Notification No. 02/2017-CT(Rate) (exemption for 1106) and "pre-packed & labelled" condition

Legal framework: Tax exemption under the Notification applies to goods falling within specified tariff items (including 1106) subject to any stated conditions (e.g., pre-packing and labelling/brand for charging specified rates). The applicability depends on correct HSN classification.

Precedent treatment: None cited; applicability determined by tariff classification outcome.

Interpretation and reasoning: Because the product was found to be a residue of starch manufacture falling under 2303 1000, it does not fall within tariff item 1106 and therefore cannot avail the exemption intended for 1106 goods. The "pre-packed and labelled"/brand condition is relevant only if the product were correctly classifiable under 1106; it does not operate to extend the exemption to goods properly classifiable elsewhere.

Ratio vs. obiter: Ratio - exemption under the cited Notification does not apply to goods classified under 2303; obiter - discussion that historical VAT exemptions do not dictate GST tariff outcomes.

Conclusion: Notification No. 02/2017-CT(Rate) entry for 1106 is not applicable to the product; the exemption cannot be claimed.

Issue 3 - Nature of the product: residue v. by-product v. waste (legal/factual test)

Legal framework: Classification under GST (and HS) distinguishes primary products from residues/waste; Chapter 23 specifically covers residues and waste from the food industries and prepared animal fodder. Dictionary/ordinary meaning of "residue" as "anything left over when a substance has been removed" applies in assessing whether material is product of the principal process or incidental leftover.

Precedent treatment: No prior decisions invoked; the Authority applied ordinary meaning and tariff structure, and examined commercial marketability and use.

Interpretation and reasoning: The Authority adopted the following tests: (a) process purpose - if the production process aims to extract starch, the fibrous leftover is not the intended primary product; (b) marketability/value - if the leftover is sold for value and used (here as animal feed), it is a residue with market value (a by-product for commercial use) rather than mere waste; (c) tariff context - Chapter 23 expressly contemplates residues/waste used in animal feed. On the facts, Stage-I manufacturers extract starch as the principal aim and the fibrous thippi is a leftover that is dried/processed and marketed by Stage-II manufacturers for animal feed, evidencing marketability and classification as residue/by-product of starch manufacture.

Ratio vs. obiter: Ratio - the factual finding that the material is a residue/by-product of starch manufacture (not primary flour) is decisive for classification under 2303; obiter - explanatory distinctions between flour, starch and uses in human consumption/industry.

Conclusion: The product is a residue (commercially marketable by-product) of the starch manufacture process and fits within Chapter 23 coverage.

Issue 4 - Tax liability and registration requirement (consequences of classification)

Legal framework: Goods classified under 2303 1000 attract GST at the rate specified in the tariff (5%). Registration thresholds and requirements are governed by Section 22 of the GST Act; advance rulings (Section 103) bind the applicant and jurisdictional officers unless relevant facts/law change, and rulings obtained by fraud are void (Section 104).

Precedent treatment: None cited; application of tariff rates and registration rules follows statutory schedule.

Interpretation and reasoning: Given classification under 2303 1000, the product is taxable at 5% under the GST Tariff. The exemption applicable to 1106 does not apply. Consequently, supplies by the trader are taxable and, subject to the conditions/thresholds of Section 22, the trader is required to register and discharge tax. The ruling also reiterates binding effect of advance rulings and the consequence of fraud/suppression of facts.

Ratio vs. obiter: Ratio - taxable character at 5% and requirement to register (subject to Section 22) flow directly from the proper classification; obiter - restatement of advance ruling binding effect and fraud clause.

Conclusion: The product attracts GST at 5% under 2303 1000 and the trader is required to register and discharge appropriate tax as per Section 22, since exemption under the 1106 notification is unavailable.
