Records, Returns and Certificates under the Concessional Duty Rules

Updated 11 October 2026 · Fact-checked

Under the Customs (Import of Goods at Concessional Rate of Duty) Rules, 2017, an importer who gets a lower duty rate for a stated end use must prove that use. You do this by keeping receipt, consumption and stock records, filing the periodic returns the Rules require, giving a certificate of use, and honouring the bond and security. Failure leads to recovery of the duty foregone with interest.

Understand Maintenance of Records, Certificates and Compliance

A concessional rate of duty is a benefit given on a condition. The condition is usually that the imported goods are used for a specified purpose, such as making a particular product. Customs has already collected less duty, so it needs proof that the condition was met. Records, returns and certificates are that proof.

Think of it as a trail from the bill of entry to the final product. At import, the importer declares the notification claimed and the intended use. After import, the importer must show where each unit went: received, stored, issued to production, consumed, wasted or still in stock. The numbers must reconcile.

The Rules use three tools. First, records of receipt, consumption and inventory of the imported goods. Second, periodic returns filed with the jurisdictional customs officer, and a certificate of use that confirms the goods were used as declared (the Rules prescribe who may certify, in what form and by when). Third, a bond with security, which lets the department recover the foregone duty if the importer defaults.

The exact due dates, the form of the certificate and the bond amount are set by the Rules and by the notification under which the concession is claimed. Read those from the bare text before the exam. Do not rely on memory of day counts.

The Customs Act has parallel ideas that help you understand the logic. Under the warehousing bond, the importer binds himself to comply with the Act, pay duty and interest, and pay penalties and fines. Under provisional assessment, the officer takes security for any shortfall in duty. The concessional duty bond works on the same principle: duty is protected by an undertaking backed by security.

Key rules to remember

Stock reconciliation of imported goods
Opening stock + Quantity received − Quantity consumed − Wastage or scrap (as permitted) = Closing stock
Your records and return must tie to this. A gap means unexplained goods, which can be treated as not used for the declared purpose.
Duty foregone on default
Duty foregone = Duty at normal rate − Duty paid at concessional rate
This is the base for recovery if the end-use condition fails. Interest and any penalty are added as the law provides.
Warehousing bond amount (Section 59(1), Customs Act)
Bond = 3 × duty assessed on the goods
Given in the Act text for warehoused goods. Do not apply it to the concessional duty bond. The Rules have their own bond terms.
Bond on excess duty after provisional assessment of warehoused goods (Section 18(2)(b))
Bond = 2 × excess of final duty over provisional duty
The proper officer may require this when final duty exceeds provisional duty on warehoused goods.

How to solve Maintenance of Records, Certificates and Compliance questions

Use this method for any question on records, returns, certificates, bond or security under the concessional duty rules.

  1. 1Identify the importer's claim: which notification, which goods, and the declared end use.
  2. 2List the obligations that follow import: records of receipt, consumption and inventory, periodic returns, certificate of use, and bond and security.
  3. 3Check each fact in the question against these obligations. Look for a missing record, a late return, an unsupported certificate or a use different from the one declared.
  4. 4Reconcile quantities using the stock formula. Flag any shortfall or unexplained use.
  5. 5State the consequence: if the condition is not met, the duty foregone becomes recoverable with interest, and the bond and security can be enforced.
  6. 6Quote the rule in plain words. Give a section number only for provisions you are sure of, such as Section 59 or Section 18.
  7. 7End with a clear conclusion: compliant or not, and what the importer must do now.

Quickest way: Four-check compliance scan

When to use it: Use this for MCQs and short case scenarios where you must decide quickly whether the importer has complied.

  1. Check 1, Use: was the imported item used for the declared purpose, and only that?
  2. Check 2, Records: do receipt, consumption and inventory figures reconcile?
  3. Check 3, Filing: were returns and the certificate of use furnished in the form and time the Rules require?
  4. Check 4, Security: is a valid bond and security in place?
  5. If any check fails, the answer is non-compliance with duty recovery and interest. If all four pass, the concession stands.

Common mistakes in Maintenance of Records, Certificates and Compliance

  • Applying the Section 59 warehousing bond rule of three times the duty to the concessional duty bond.

    Both are customs bonds and the 'thrice the duty' figure is easy to remember.

    Fix: Treat Section 59 as the rule for warehoused goods only. For the concessional duty bond, follow the Rules and the notification.

  • Thinking that a certificate of use alone is enough proof.

    Students see the certificate as the final document and forget the records behind it.

    Fix: The certificate is backed by receipt, consumption and inventory records. If these do not reconcile, the certificate does not protect the importer.

  • Treating returns as optional once duty is paid.

    The importer has already cleared the goods, so the matter feels closed.

    Fix: The concession is conditional. Periodic returns are part of the condition, and default can reopen the duty.

  • Quoting exact day limits or certifying authorities from memory.

    Timelines are numerous and look similar across rules.

    Fix: State the duty in principle, and give a figure only if you are sure of it from the Rules text.

  • Ignoring the importer's own responsibility for the bill of entry.

    Students focus on post-import compliance only.

    Fix: Section 46(4A) makes the importer responsible for accurate and complete information, valid supporting documents and compliance with any restriction or prohibition.

  • Writing only the rule and no conclusion in a case answer.

    Students treat the question as recall.

    Fix: Apply the rule to the facts and end with a clear finding and the action required.

Worked examples

Example 1

Metro Polymers Ltd imported 10,000 kg of a raw material at a concessional rate for use in a specified product. Its records show: received 10,000 kg; issued to production and consumed 7,200 kg; permitted wastage 300 kg; physical stock in the store 2,000 kg. Is the position reconcilable? What should the importer do?

Show the solution
  1. Expected closing stock = 10,000 − 7,200 − 300 = 2,500 kg.
  2. Physical stock is 2,000 kg.
  3. Unexplained difference = 2,500 − 2,000 = 500 kg.
  4. The records do not reconcile. The 500 kg cannot be shown as used for the declared purpose.
  5. The importer should investigate, correct any recording errors and support the gap with documents. If it cannot be explained, the duty foregone on that quantity is exposed to recovery with interest.

Answer: The records do not reconcile. There is an unexplained shortfall of 500 kg. The importer must explain or document it. Otherwise, duty foregone on that quantity can be recovered with interest under the Rules.

Example 2

Distinguish the bond for warehoused goods under Section 59 of the Customs Act from security in provisional assessment, with figures. Duty assessed on warehoused goods is ₹4,20,000. After provisional assessment of other warehoused goods, final duty exceeds provisional duty by ₹1,75,000. Compute the bonds.

Show the solution
  1. Section 59(1): the warehousing bond is a sum equal to thrice the duty assessed.
  2. Bond = 3 × ₹4,20,000 = ₹12,60,000.
  3. Section 18(2)(b): for warehoused goods under provisional assessment, the proper officer may require a bond binding the importer in a sum equal to twice the excess duty.
  4. Bond = 2 × ₹1,75,000 = ₹3,50,000.
  5. Under Section 18(1), the provisional assessment itself depends on the importer furnishing security the proper officer considers fit for the deficiency, if any, in duty.
  6. Link to the concessional duty rules: they follow the same logic of securing duty with a bond and security. Their own bond terms govern.

Answer: Section 59 bond: ₹12,60,000. Section 18(2)(b) bond: ₹3,50,000. These are Customs Act rules for warehoused goods. The concessional duty bond is governed by the Rules and the notification.

Exam tips

  • Expect a case scenario with 'did the importer comply?' Use the four-check scan and decide.
  • In MCQs, watch for options mixing the Section 59 'thrice the duty' figure with the concessional duty bond. Keep them separate.
  • In written answers, name the three compliance tools (records, returns with certificate, bond and security) and then apply them to the facts.
  • Practise a stock reconciliation. Numerical questions on this topic are usually simple quantity checks.
  • Verify any day limits and certifying authorities from the Rules text. Do not guess them in an answer.

Maintenance of Records, Certificates and Compliance: frequently asked questions

What records must an importer keep under the concessional duty rules?

The importer must keep records of receipt, consumption and inventory of the imported goods. They must show where each lot went and whether it was used for the declared purpose. Keep them reconciled with the returns.

What is a certificate of use?

It is a certificate confirming that the imported goods were used for the purpose declared when the concession was claimed. The Rules prescribe its form, who may give it and when. Check the Rules text for these details.

Is a bond always needed for concessional duty imports?

The Rules require the importer to give a bond with security as an undertaking to comply with the conditions and protect the duty foregone. The terms are set by the Rules and the notification. Do not confuse them with the Section 59 warehousing bond.

What happens if the importer fails to comply?

The concession is lost for the goods concerned. The duty foregone becomes payable with interest, and the bond and security can be enforced. See the topic on non-compliance, duty recovery and interest for the details.
