Periodicity of CAS-4 certificates: issue by the year-end following the financial year to allow assessment finalisation.
CAS-4 certificates must be issued to reflect cost of production for captively consumed goods in accordance with CAS-4 methodology; certificates for a financial year ending 31 March are required to be issued by 31 December of the next financial year, after which provisional assessments will be finalised.

Classification of saree: further processing or multi fabric construction does not move it from specific textile headings to made up articles.
Sarees that undergo embroidery, lace stitching, tikki application or are stitched from two or more textile materials remain classifiable under the specific saree headings in Chapters 50, 52 or 54 of the Central Excise Tariff Act, 1985 rather than under the more general Chapter 63. Where multiple materials are present, Section XI Note 2(A) directs classification according to the textile material that predominates by weight, or, if none predominates, by the heading occurring last in numerical order among equally applicable headings. Further processing that does not create a new article with distinct name, character and use does not change this classification; individual cases must be decided on their facts.

CAS-4 certificate deadlines require issuance by December 31 following the financial year to enable provisional assessment.
Assessees must issue CAS-4 certificates for the financial year ending 31 March by 31 December of the following financial year to enable calculation of cost of production for captively consumed goods; assessing officers must then finalize provisional assessments expeditiously and jurisdictional commissioners shall provide trade facilitation, with implementation difficulties to be reported to the Board.

Annual return requirement suspended pending GST implementation; annual returns for non-GST goods may be required thereafter.
Central Board amendments replaced Central Excise Forms ER-4 to ER-7 with a consolidated Annual Return under Central Excise, CENVAT Credit and Service Tax rules, originally requiring filing by 30 November; a Board circular deferred filing for the specified year due to impending GST implementation and stated that post-GST an annual return may be required for non-GST goods. Trade associations are asked to publicize the change and report implementation difficulties to local offices.

Provisional registration for existing excise/service taxpayers will be issued on PAN and communicated for migration to GSTN.
Existing Central Excise and Service Tax registrants with a valid PAN will receive provisional registration under GST; GSTN will generate provisional IDs and passwords and communicate them securely via the ACES portal. The Directorate General of Systems has arranged secure transmission, and the Commissionerate has nominated nodal officers to assist taxpayers; trade is requested to utilise these services for migration to GSTN.

Change of Advance Rulings office address notified; trade associations must publicize relocation and inform constituents.
Notification reiterates relocation of the Authority of Advance Rulings for Central Excise, Customs & Service Tax to a new office address, referencing the earlier Public Notice. Trade associations, chambers of commerce and members of the Regional Advisory Committee are directed to widely publicize the new address among their constituents so that applications, communications and enquiries reach the relocated Authority; departmental file reference for the communication is noted.

Migration of Central Excise/Service Tax assessees to GST requires provisional ID, PAN update, and submission via GSTN portal.
Existing Central Excise and Service Tax assessees with a valid PAN will receive provisional registration under the draft CGST Act: CBEC forwards data to GSTN, which issues provisional ID/password; assessees must log into GSTN, verify non-editable fields, submit GST REG 20, obtain an ARN, be marked "MIGRATED" and, after verification, receive GSTIN (Form 6) and activation on the GST rollout date. Registrations lacking a PAN must obtain and update PAN on ACES before migration.
