Classification of polyols and isocyanates: components with additives must be assessed individually on merits for excise assessment
Polyols and isocyanates presented together for sale, even when containing additives such as fillers, plasticisers, flame-proofing agents, pigments, blowing agents, catalysts or foam stabilizers, must be classified and assessed individually on their merits; these additives are permitted additions that do not alter the constituent products' classification or convert them into a single "set." The Board accepts the technical opinion and directs field formations and trade to finalise pending assessments accordingly.

End-use certification requirement for bulk drugs to secure central excise exemption; manufacturers must prove intended pharmaceutical use.
Manufacturers of "other bulk drugs" must produce certificates proving that the goods are used as bulk drugs or as ingredients in formulations to qualify for the excise exemption; authorities should insist on such end use proof because the exemption is to be read with the statutory definitions that limit relief to substances actually used as such or as ingredients in drug formulations.

Duty exemption for intermediate goods used in domestic manufacture for export under bond applies to normal levies.
No duty need be collected on intermediate goods produced and used in the same factory in the manufacture of finished excisable goods exported under bond, irrespective of whether there is any provision permitting deferment or non-payment of duty on these intermediate goods; this non-collection principle, introduced to avoid compounded levy on inputs used in exported manufactures, applies equally to normal levies.

Classification of enzymes: bulk unmixed enzymes fall under the enzymes heading rather than as medicaments.
Products sold in bulk and unmixed like papain, pancreatin and various amylases do not satisfy the chapter 30 note conditions for medicaments (compounded products or unmixed products presented in measured doses or retail/hospital packings). The HSN Explanatory Notes specifically list these enzymes under the enzymes heading; accordingly such enzymes should be classified under the enzymes heading of chapter 35 rather than as medicaments under chapter 30, and field formations and trade are to be advised.

Deemed Modvat credit: permitted on inputs supplied to job workers unless inputs are clearly non-duty paid or nil-rated.
Deemed Modvat credit is permitted on all inputs received by manufacturers, including those sent to job workers, unless such inputs are clearly recognisable as non-duty paid or chargeable to nil rate of duty; pending cases should be disposed accordingly and field formations and trade informed.

Registered Exporters and Export Houses defined per Import-Export Policy for interpretation in Central Excise instructions.
The circular states that the terms Registered Exporters and Export Houses used in Board instructions for Central Excise shall be given the same meaning as in paragraphs 6(6) and 6(7) of the Import-Export Policy, and urges that field formations be advised accordingly to ensure consistent administrative application.

Manufacture recharacterizes cutting, slitting and perforation of jumbo film rolls as production of finished cinematographic film, altering duty.
Cutting, slitting and perforation of imported jumbo rolls (1.15-1.455 m) are processes that convert an intermediate jumbo roll into a finished, ready for use cinematographic film and therefore amount to manufacture. Consequently, imported jumbo rolls are classifiable under sub heading 3702.90 and attract the concessional duty under the exemption notification, while the finished perforated and slit cinematographic films are classifiable under sub heading 3702.20 and attract the tariff duty applicable to finished film. Earlier instructions are modified and pending assessments finalised on this basis.

Classification of printed waxed wrapping paper: treated as converted paper and eligible for exemption under converted-paper heading.
Printed waxed wrapping paper is not a product of the printing industry when printing is merely incidental to its primary use; instead it is classifiable as converted paper. Converted paper encompasses wet and dry processes and expressly includes waxed paper, and printed waxed wrapping paper therefore falls within the tariff heading for converted paper and is eligible for the exemption applicable to converted paper. Pending assessments should be finalised in accordance with this classification.

Classification of reduction gear housing: Portal treated as a part of motor vehicles under the parts heading for vehicle assemblies.
The 'Portal' is a casing for wheel reduction gear assemblies that reduces wheel RPM and protects drive shafts. Under the HSN Explanatory Notes to Heading 87.08, reduction gear assemblies and casings for gearboxes, differentials and drive axles are parts of motor vehicles; therefore the 'Portal' is classifiable under Heading 87.08 of the CET and field formations should apply this classification.

Classification of wall coverings: end use and character determine tariff placement under Heading 48.14 for wall coverings.
Textile or textile-surfaced articles marketed and used as wall coverings are classifiable under Heading 48.14 of the Central Excise Tariff based on the character and end use of the article, notwithstanding narrower scope in HSN notes; the CET does not adopt the HSN width restriction, and articles of narrower width known and used as wall coverings may also fall under this heading.

Terpeneol classification: bulk treated as cyclic alcohol; therapeutically packaged, measured-dose products qualify as medicament.
Terpeneol is classifiable as a cyclic alcohol under heading No. 29.06 (previously No. 29.02) in its bulk/commercial form. It will be classifiable under heading No. 30.03 as a medicament only when it is suitable for therapeutic or prophylactic use and is an unmixed product put up in measured doses or in packings for retail sale or for use in hospitals. Field formations are to apply these principles and finalise pending assessments.

Classification of magnetic ferrite as a chemical intermediate: treated under chemical tariff heading and captive use attracts no duty recovery.
Magnetic ferrite with a binder in powder or pellet form, produced by grinding, drying and calcining of iron-oxide and carbonates, is classifiable under the chemical tariff heading corresponding to ferrites; the Board endorsed this classification and specified retrospective CET subheading treatment. When captively consumed in manufacture of dutiable finished magnet articles, no duty is recoverable under the cited notification, and pending assessments are to be finalised accordingly.

Classification of printed tops: flattened printed sheets for hosiery packing treated as coated paper, not unfinished cartons.
Flattened printed sheets of paper or paperboard used as removable tops for hosiery packing are classifiable as paper and paperboard coated, impregnated or covered with plastic rather than as unfinished cartons; they are sheets only and should not be treated as incomplete boxes under rules of interpretation.

Notification applicability limited to new units commencing production after the operative date; expansions and modernisations excluded.
Notification No. 36/87-C.E. is limited to new units commencing cement production on or after the operative date; substantial expansion or modernisation of existing factories do not qualify unless the work results in a totally independent unit that has come into production after the operative date. Field formations and trade are to be informed and pending assessments finalised accordingly.

Tariff classification: processed speciality oils treated as aromatic petroleum products, therefore classifiable as similar aromatic residues.
Processed speciality oils obtained by blending furfural extracts are individually identifiable rubber processing oils and thus do not remain classifiable as "other residues of petroleum oils"; because aromatic constituents predominate under Chapter Note 2 of Chapter 27, such processed oils are appropriately classifiable under the heading for similar aromatic products, and pending assessments should be finalised on that basis.

Classification of Terpeneol as cyclic alcohol: bulk supplies fall under the chemical heading, packaged therapeutic doses qualify as medicament.
Terpeneol BP/BPC is generally classifiable as a cyclic alcohol under the chemical tariff heading when in bulk or commercial form; it is classifiable as a medicament only if it is an unmixed product suitable for therapeutic or prophylactic use and put up in measured doses or packings for retail sale or hospital use. Field formations and trade are to be advised and pending assessments finalised on this basis.

Set-off of additional duty on imports requires an express notification provision; additional duty is not treated as excise duty.
Set-off under Notification No. 432/86-C.E. is confined to duty of excise as defined under the Central Excises and Salt Act, 1944, and does not extend to additional duty levied under the Customs Tariff Act, 1975. Additional duty, though charged at a rate equivalent to excise, is not equivalent in legal character and can be set off only where a notification expressly provides for such set-off; pending assessments should be finalised on this basis.

Classification of polyurethane foam: moulded products lacking a separate primary form are treated as finished polyurethane goods.
Moulded polyurethane foam produced by pouring reactive mixture into predetermined moulds does not yield a separate primary form; such goods must be classified as finished polyurethane goods. Moulded blocks that are uniform in predetermined dimensions constitute blocks of regular geometric shape and are classifiable as blocks, whereas moulded items serving specific purposes are classifiable as articles of polyurethane foam.

Classification of carbon electrode paste and blocks as preparations based on carbon under tariff heading 38.01 is confirmed.
Carbon electrode paste and blocks produced from anthracite/calcined petroleum coke with binder pitch differ from baked electrodes in conductivity, resistivity, mechanical strength, volatiles and thermal behaviour; these distinctions lead to their classification as "preparations based on graphite or other carbon in the form of paste, block, plates or other semi-manufactures" and therefore as classifiable under heading 38.01 of the Central Excise Tariff.

Consolidation of excise notifications prompts administrative clarifications on Rule 174A and invites further queries to the Board.
The Board clarified implications of the consolidation effected by Notification No. 11/88 Central Excises (N.T.), which merged prior notifications issued under Rule 174A. Specific doubts raised were examined and addressed in an annexure listing detailed clarifications on how the consolidated notification relates to earlier notifications and administrative practice. Remaining uncertainties are to be referred to the Board for further guidance.
