Quick summary

India accepts an FAA Form 8130-3 on a new part far more readily than most buyers assume — the bilateral wording is specific about which parts qualify, and used serviceable material does not travel the same route. Two tax changes have since removed most of the cost argument against importing: a uniform 5 % GST on all aircraft and engine parts from July 2024, and a basic customs duty exemption on aircraft components announced in the Union Budget on 1 February 2026. What still stops shipments is paperwork that does not match the part.

The acceptance question is narrower than it looks

Operators in South Asia routinely ask sellers a version of the same question: “will our regulator accept this release certificate?” The honest answer is that the regulator is rarely the party that rejects the part. The operator’s own quality department rejects it, because the certificate on the box does not cover the condition the part is actually in.

For India the governing text is the Implementation Procedures for Airworthiness under the FAA–DGCA bilateral agreement, dated 17 November 2011. It says the DGCA accepts FAA Form 8130-3 on new modification, replacement and standard parts that have “been produced by a U.S. production approval holder (i.e., under a U.S. TC, Production Certificate, TSOA, or a Parts Manufacturer Approval)”. The part must be eligible for installation in a product that holds a Letter of Type Acceptance under CAR 21, or in an article the DGCA has accepted; it must conform to FAA-approved design data accepted or approved by the DGCA; and it must be safe for installation.

Three things follow from that wording, and they are the three things sellers get wrong.

First, the clause is about production, not about maintenance. It covers parts leaving a production approval holder. A used serviceable unit released by a repair station after overhaul is a different animal — it is a maintenance release, and its acceptability rests on the receiving organisation’s own procedures rather than on this paragraph. Quoting the bilateral at a quality manager who is looking at a teardown unit does not answer his question.

Second, the eligibility test is aircraft-specific. The part has to be eligible for installation in a product accepted by the DGCA. A tag that is faultless in itself does not help if the effectivity does not cover the operator’s fleet. Effectivity mismatches are the single most common reason a correctly certified part sits in a bonded warehouse in Delhi.

Third, the DGCA reserves additional requirements. The text requires that each part “meets all additional requirements prescribed by the DGCA, as notified by the DGCA”. That is an open door, and it is why a seller should never promise a buyer that a part will clear. The seller’s job is to supply complete, traceable documentation; the acceptance decision belongs to the operator and its regulator.

The bilateral also handles the humble end of the range: standard parts that are not eligible for a Form 8130-3 may instead be accepted with a manufacturer’s Certificate of Conformity verifying conformance to an established U.S. specification. Sellers who pad a shipment of fasteners with a certificate the form was never meant to carry create suspicion where none was needed.

A Letter of Type Acceptance is not a parts document

LoTA comes up constantly in South Asian sourcing conversations and is almost always misunderstood. Per the FAA’s country-specific guidance for India, revised 12 November 2024, the DGCA issues a Letter of Type Acceptance “under provisions of Aircraft Rule 49B, CAR 21, Subpart B”. It is a type-level instrument, covering type certificates and supplemental type certificates — the aircraft or the modification, not the line item.

The documentation the DGCA asks for makes that clear: for a type certificate, the applicant submits the original TC and data sheet, the approved flight manual, compliance documentation against special conditions, HIRF test results, verification of operational capability from high-altitude and high-temperature environments, ICAO noise and emissions compliance, a letter of intent from the Indian customer or operator, and aircraft age restriction documentation. For an STC, the file includes a description of the change with make and model, the FAA certification basis with exemption details, compliance methodology and an installation schedule for Indian-registered aircraft.

None of that is something a component seller produces. If a buyer asks you for “the LoTA for this part”, they are asking the wrong question, and the useful reply is to establish which aircraft the part is going onto and whether that type is already accepted.

What changed on the money side

The cost case for importing into India used to be genuinely bad, and two reforms have largely fixed it.

In July 2024 India moved to a uniform Goods and Services Tax rate of 5 % on all aircraft and aircraft engine parts, replacing a range that had run from 5 % to 28 %. The scatter of rates had produced an inverted duty structure and left input tax credit accumulating in MRO accounts — money that shops could not release. The measure took effect on 15 July 2024.

Then, in the Union Budget presented on 1 February 2026, the Finance Minister proposed exempting basic customs duty on components and parts for civilian aircraft manufacture, on training aircraft components, and on raw materials for aircraft parts used in MRO activity by defence sector units. Reporting on the measure put the previous duty band at 7.5–15 %. Boeing’s assessment was that the change would reduce manufacturing costs by 5–7 % and lower maintenance expenditure in India directly, with a company representative saying that “by exempting basic customs duty on raw materials and components, the government has lowered entry barriers and reduced costs for manufacturers”.

Alongside the tax measures sit procedural changes that matter more to day-to-day sourcing than the headline rates. The permitted stay for a foreign aircraft in India for MRO work went from 15 days to six months. The requirement for MROs to furnish parts documentation or client orders at import was removed. Foreign direct investment in MRO services is permitted at 100 % through the automatic route. India’s civil aviation minister expects the domestic MRO industry to reach $4 billion by 2030 from roughly $2 billion today, and Vision 2040 targets handling about 90 % of domestic carriers’ MRO needs at home.

The demand behind those numbers is not speculative. Boeing projects India and South Asia will need roughly 3,300 new commercial aircraft over the next two decades, more than $195 billion of aviation services, and about 141,000 aviation professionals including 45,000 pilots and 45,000 technicians.

One structural note for anyone planning a long horizon: since 1 January 2025 the legal foundation is the Bharatiya Vayuyan Adhiniyam, 2024 (Act No. 16 of 2024), which replaced the ninety-year-old Aircraft Act, 1934 and covers the regulation and control of the design, manufacture, maintenance, possession, use, operation, sale, export and import of aircraft. References to the 1934 Act in older contracts and quality manuals will drift out of date.

Pakistan: the constraint is rarely the certificate

Pakistan illustrates a point that is easy to miss when the whole conversation is about forms. In December 2024, 17 of Pakistan International Airlines’ 34 aircraft were out of service for want of components: seven of twelve Boeing 777s, seven of seventeen Airbus A320s, and three of five ATRs, leaving two ATRs active. The missing items were engines, landing gear, auxiliary power units and other vital parts. The reported causes were a shortage of funds and pending clearance from the relevant ministries.

Nothing in that story is a documentation failure. It is a payment and authorisation failure, and it is the pattern across much of the region: the part exists, the certificate is fine, and the transaction cannot close. For a seller, the practical consequence is that a Pakistani enquiry needs a payment structure discussed at the quotation stage, not after the quote is accepted. For a buyer, it means the airworthiness file is the easy half of the job.

The same dynamic drives cannibalisation, which quietly makes the next purchase harder: a unit robbed from a grounded airframe arrives at the shop with a paper trail that has to be reconstructed, and reconstructed traceability is exactly what a receiving inspector is trained to distrust.

Bangladesh: verify locally, do not assume

Bangladesh’s Civil Aviation Authority publishes its airworthiness requirements as Air Navigation Orders in a Part-21 and Part-M structure familiar to anyone who has worked to European rules. We were not able to retrieve the current issues of those orders from the authority’s servers while preparing this piece, so we are not going to paraphrase clauses we have not read — that is precisely the habit that puts wrong information into a purchase order.

The workable approach for a seller is the one that works everywhere: ask the buyer’s continuing airworthiness organisation which release documents its own exposition permits it to accept, and get that answer in writing before shipping. The operator’s approved procedures are the binding document in the transaction. A regulator’s general rule is context; the exposition is the contract.

What to attach before the part moves

A shipment into any of these three markets should leave with a file, not a tag. In practice that means the release certificate itself, complete and legible, with the issuing organisation’s approval reference; the certificate of conformity where the item is a standard part; traceability back to a source the buyer can name, not merely to the last holder; the effectivity evidence showing the part number is approved for the buyer’s aircraft type and configuration; and, for used material, the maintenance history and the workscope actually performed rather than a generic overhaul claim.

Two further items save weeks. The commercial invoice should describe the part in terms customs can match to the tariff line, using the same nomenclature as the certificate — mismatches between the tag description and the invoice description are a routine cause of holds. And the packing should let an inspector verify the part against the paperwork without breaking a seal that then has to be re-certified.

None of this is exotic. It is the same discipline that an operator without its own CAMO has to apply on receipt, viewed from the selling side. Sellers who build the file once and reuse the structure close faster in every market, and the effort transfers directly to the customs documentation problem in African markets, where the failure modes rhyme even though the rules differ.

How this changes a sourcing decision

Put the three markets side by side and the practical guidance separates cleanly. In India, the regulatory path for new US-origin parts is well defined and the tax friction has largely been removed, so the deciding factor is effectivity and lead time rather than duty. In Pakistan, assume the constraint is funding and clearance, and structure the deal accordingly. In Bangladesh, assume nothing and get the operator’s acceptance criteria in writing first.

Across all three, the seller who wins is the one whose documentation answers the receiving inspector’s questions before they are asked. That is also why payment structure and documentation quality tend to move together: a buyer who cannot verify the part will not release funds, and a seller who cannot secure funds will not ship first. Escrow resolves the standoff by making the two conditions simultaneous rather than sequential — the same logic that governs cross-border payment under currency controls.

If you are sourcing for a South Asian operator now, the fastest route to a real quote is to put the requirement in front of verified sellers with the effectivity stated up front: submit an RFQ on Aviatrading with the part number, aircraft type and acceptable condition codes, and let the documentation question be settled before anyone commits money. For planning rather than an immediate need, the parts catalogue shows what is already available against the platforms flying in the region, and live requirements from other buyers run continuously on our Telegram channel.

The regional context for routing and lead time is covered separately in our note on routing parts through hub airports, which applies to South Asian consolidation points as much as to African ones.
