Authority for Advance Ruling

This page was written by Patron Accounting’s AI from the official release and reviewed before publishing. It explains the document in plain language. It is not the document itself. Where this page and the original differ, the original governs.

The short version

  1. Ratan Projects asked if consumed materials count as a taxable supply.
  2. The Authority ruled that consumed materials are not a supply.
  3. Returning the finished galvanised goods satisfies the legal requirement.
  4. Physical return of exhausted consumables is not required.

In short

The company asked the West Bengal Authority for Advance Ruling (AAR) if sending materials like furnace oil, zinc, and nickel to a job worker counts as a taxable supply if those materials are not returned. Under Goods and Services Tax (GST) law, businesses usually must receive inputs back from a job worker within a set time. The question was whether the law requires the physical return of materials that are completely used up during the manufacturing process.

What has changed

How it worked before

Businesses were uncertain if they had to pay GST on consumables that were exhausted during job work, fearing the tax department might treat the non-return of these items as a deemed sale.

What has changed

The Authority decided that if materials are entirely consumed during the galvanising process, they do not need to be returned. Returning the final processed goods is enough to satisfy the law. This means businesses do not have to pay GST on these consumed items as if they were a separate supply.

Who this affects

Manufacturers who send raw materials and consumables to job workers for processes like galvanising where the consumables are fully used up.

An example

A steel furniture maker sends metal frames and paint to a job worker. The paint is entirely used up to coat the frames. Under this ruling, the furniture maker does not need to worry about the paint not being returned, provided the finished painted frames are sent back. They would not treat the consumed paint as a taxable supply.

What you should do

If you are in a similar situation, you should document that your materials are fully consumed during the process. Remember that an Advance Ruling only binds the business that asked for it and their specific tax office. You cannot automatically apply this decision to your own business without checking your specific facts with a tax professional.

If you do nothing

If you assume this ruling applies to you and it does not, you risk a tax demand for unpaid GST on the 'deemed supply' of those materials. A tax officer may disagree with your interpretation, leading to penalties and interest. Always verify your specific process with an expert before deciding not to account for these items as supplies.

The terms explained

Job worker
A person or business that performs a manufacturing process on goods owned by another business.
Consumables
Materials that are used up or exhausted during a manufacturing process, such as oil or chemicals.
Deemed supply

The ruling in detail

Authority for Advance Ruling

Ratan Projects & Engineering Co Private Limited

49/WBAAR/2018-19 dated 28/03/2019 · West Bengal

Questions before the authority

  • Whether dispatch of consumable materials like furnace oil, zinc, and nickel to a job worker is to be treated as supply from the principal to the job worker if they are not returned within the time allowed under section 143(1)(a) of the GST Act.

Facts

The applicant manufactures cable trays and sends steel structures to a job worker for galvanising. Along with the steel, the applicant provides consumables including furnace oil, zinc, and nickel which are consumed during the galvanising process. The applicant sought a ruling on whether the non-return of these consumed materials constitutes a taxable supply under section 143(3) of the GST Act.

Ruling

QuestionWhat the authority ruled
Consumables sent to job workerNot a supply
Provided they are entirely consumed in the galvanising process and inseparable from the galvanised goods.

The Authority held that the return of the galvanised goods satisfies the condition of receiving back inputs under section 143(1)(a). It ruled that the consumed materials should not be treated as a supply under section 143(3) provided they are entirely used up in the galvanising process.

Reasoning

The Authority reasoned that galvanising is an intermediate manufacturing process where inputs are consumed. Relying on the Explanation to section 143, it determined that 'inputs' include intermediate goods where the original materials are embedded or consumed. Citing judicial precedent, it concluded that the requirement to return inputs does not necessitate the physical return of materials that have been exhausted during the process. Therefore, the return of the galvanised structure itself constitutes sufficient compliance with the law.

Provisions relied on

  • Section 2(68) of the GST Act
  • Section 97(2)(g) of the GST Act
  • Section 100(1) of the GST Act
  • Section 103 of the GST Act
  • Section 104(1) of the GST Act
  • Section 143(1)(a) of the GST Act
  • Section 143(3) of the GST Act

For the practitioner

This ruling provides **significant relief** to manufacturers who send raw materials for galvanising, confirming that consumed consumables do not trigger a deemed supply liability. It clarifies that the physical return of exhausted inputs is not required if the final processed goods are returned. However, practitioners should note that this ruling is **fact-specific** and relies on the materials being entirely consumed in the process.

Is this ruling binding on my business?

No. An Advance Ruling only applies to the business that requested it. It serves as a guide for how the department might view similar cases, but it is not a law that applies to everyone.

What if my tax officer disagrees with this ruling?

Since this ruling is not a law, your local tax officer is not required to follow it. If they disagree, you would need to present your own facts and legal arguments to support your position.

Does this apply if the materials are not fully consumed?

No. This ruling specifically relies on the fact that the materials are entirely used up in the process. If you have leftover materials that are not returned, the tax department may treat them differently.
