Classification of vehicle-mounted drilling rigs as special-purpose motor vehicles alters excise treatment and valuation approach.
Drilling rigs mounted on motor vehicle chassis are excluded from the machinery heading by HSN Explanatory Notes and are classifiable as special purpose motor vehicles under Heading 87.05; this classification affects excise treatment and requires assessable value determination following Board guidance applicable to motor vehicles incorporating chassis components.

Delayed proof of export: provisional bond credit allowed after statutory waiting period on banker and post office certificates.
Where postal proof of export is not received within six months from despatch, provisional credit in the exporter's running bond account may be allowed based on a banker's certificate certifying receipt of sale proceeds, supported by a certificate from the local post office where the parcel was registered that the export parcel has not been received back.

Classification of cassette housings as parts of recording media confirmed; covers classed as plastic packing articles.
Plastic cassette housings/casings are integral precision parts of audio cassettes and classifiable as parts of recording/unrecorded media under Chapter 85 (8523/8524); plastic covers are non essential packing/handling accessories and classifiable as articles of plastics under sub heading 3923.

Classification of printed packaging materials clarified: primary use controls tariff chapter allocation under excise rules.
Classification of printed wrapping, labels, films, sheets, laminates and pouches is governed by the primary function of the article: where printing is incidental to packaging, the goods fall under the tariff headings for paper or plastics rather than as products of the printing industry. Printed plastic films/sheets and laminates of plastic with plastic are classifiable as plastics products; paper/plastic laminates are classified according to which material predominates by thickness; aluminium foil below the prescribed thinness is classifiable as aluminium foil irrespective of backing.

Classification of vehicle tanks as motor vehicle bodies clarifies excise treatment and exemption eligibility for road tankers.
Tanks/containers fabricated for mounting on motor vehicle chassis lack identity as separate container goods and are specially designed solely for use on chassis, and therefore are to be classified as fabrication of bodies or parts of bodies for motor vehicles, trailers or tanker wagons rather than as separate container headings; such fabricated tanks are eligible for exemption benefits if the final motor vehicles pay duty at the appropriate rates under the relevant exemption provision.

Concessional duty classification: imported bare and metallised plastic films attract the higher concessional duty due to material origin.
Imported bare plastic films are chargeable to Central Excise at the higher concessional ad valorem rate because the raw plastics imported under headings 38.01-39.15 did not bear Central Excise or Countervailing duty; metallised or laminated films manufactured in India from such duty-paid imported bare films are likewise chargeable at the higher concessional ad valorem rate rather than the lower concessional rate, and prior Board instructions cited do not apply; field formations and trade should be informed and pending assessments finalised on this basis.

Classification of squashes: treated as fruit juice preparations for excise classification, not as beverage preparations.
Squashes made from fruit juice, including those with permitted additives and sweetening matter, are preparations of fruit juice and, per the Tribunal's interpretation of the Fruit Products Order, 1955, are correctly classifiable under heading 20.01 of the Central Excise Tariff; the Board has accepted this position, directing that such squashes not be treated under heading 21.07 for beverage preparations.

Cess liability on tea waste: export-bound clearances without excise duty still attract cess absent a specific rules exemption.
An exemption notification under the Central Excise Act does not ipso facto exempt goods from cess; cess is leviable unless specifically exempted under the Central Excise Rules, 1944. A separate notification under the rules is required to permit clearance of tea waste without payment of cess; since no such notification under Rule 191B exists, cess is payable on tea waste cleared under bond without Central Excise duty.

Classification of thermolloyd polystyrene as regular geometric blocks places it under shaped plastic blocks headings, not sheet heading.
Product produced by feeding polystyrene into a performer and moulding into blocks of regular geometric shape, later cut into sheets or plates, is not classifiable under the tariff subheading for finished plastic sheets but is classifiable under the headings that cover blocks of regular geometric shape, per Note 10 of Chapter 39; the geometric block form governs classification.

Proper citation of evidential documents ensures timely adjudication by requiring specific document and page references in show cause notices.
Show cause notices must not refer broadly to entire seized files; they should identify precisely the specific documents and page numbers relied upon for framing charges. Sorting and sifting of seized records is required at the drafting stage so that only the identified documents/pages are cited, narrowing inspection scope, preventing dilatory tactics, and enabling timely adjudication.

Excisability of lean gas clarified; administrative guidance corrected to read 'at the ground level' in prior Board letter.
Question whether a mixture of crude gases termed "Lean gas", produced during Carbon Black manufacture, is subject to central excise; and administrative correction to prior Board guidance replacing the phrase 'under the ground' with 'at the ground level' in para 2 of the Board's letter dated 22-12-1988.

Classification of hot rolled iron and steel as rolled or forged shapes changes tariff treatment; pending assessments to be settled.
A classification dispute concerned hot rolled iron or steel under specified dimensions produced before 1-8-1983, contested between treatment as hoops and as other rolled, forged or extruded shapes and sections. A tribunal held they fall within the residual category of other rolled/forged/extruded shapes rather than hoops; the department's petition was dismissed and the Board directed that pending assessments be settled in accordance with that tribunal classification.

Pay parity: senior staff to have pay stepped up to match juniors after departmental exam increments, with arrears adjusted.
Two advance increments are allowed to certain Income Tax Department staff on passing the departmental examination; where seniors who passed before 1.1.86 received increments at pre-revised rates and now earn less than juniors, the senior's pay shall be stepped up with reference to the junior from the junior's increment date, pay to be refixed under pay rules, subsequent increment dates aligned, and arrears paid.

Advance increments on passing departmental exams continue under revised pay scales, preserving entitlement for specified income-tax staff grades.
The instruction confirms that the scheme of granting advance increments to LDCs, UDCs, Inspectors of Income-tax, Head Clerks, Supervisors and Stenographers on passing the departmental examination to the next higher grade will continue notwithstanding the revised pay scales effective from 1.1.86, with concurrence of the Department of Expenditure and the Department of Personnel and Training.

Modvat credit endorsement allowed only where entire consignment covered by subsidiary gate pass is transferred to another person.
Endorsement of subsidiary gate passes and certificates issued by public sector undertakings and canalising agencies for availing Modvat credit is permitted only if the entire material covered by such document is sent to another person; this modifies earlier Board instructions and requires field formations and trade interests to be informed.

Classification of polyols and isocyanates: assessed individually for excise duty when supplied together, not as ready-to-use sets
Notes covering goods "put up in sets" do not apply to polyols and isocyanates supplied together for polyurethane foam because the components are not ready for use after simple mixing and require additional additives and controlled chemical processing. Therefore, polyols and isocyanates should be assessed to central excise duty individually on their merits even when presented together at the time of sale or import.

Amendment to Section 11A: earlier adjudication instructions issued for the unamended provision are no longer applicable.
The Board examined queries from collectors and clarifies that instructions dated 5-6-1986, issued with reference to the unamended Section 11A, are not relevant after the amendment of Section 11A by the Central Excises & Salt (Amendment) Act, 1985, and therefore should not be applied in adjudication under the amended provision.
