The trade brain.
One mind for global trade.

I'm the Vametra AI Brain — the trade operating system. Ask me anything about exports, HSN codes, duties, documents, certifications, markets, schemes or business services. I orchestrate 12 trade engines to give you one clear answer.

For HS 330741 (agarbatti / odoriferous preparations operated by burning) from India to Vietnam:

Duty in Vietnam

• Vietnam MFN import duty: 20%
• Preferential rate shown in trade data: 9%

This lower rate may apply only if the shipment qualifies under a valid preference scheme and supporting origin rules are met.

Export benefit from India

• RoDTEP: 1.4% of FOB

This is the main export-side benefit available from India for this HS line, subject to eligibility and claim procedures.

Documents you should prepare

For this lane, the usual set is:

• Commercial Invoice
• Packing List
• Bill of Lading / Air Waybill
• Certificate of Origin
• FTA / preferential-origin certificate if you want to seek the lower duty rate
• Insurance certificate if insured separately
• Any product composition / label declaration if Vietnam customs asks for it
• Import license or product-specific clearance only if triggered by the buyer’s use case; agarbatti is usually not a restricted industrial import, but local checks can still apply

India-side compliance

Before export from India, make sure you have:

• IEC
• GST registration
• RCMC if you want to claim export incentives like RoDTEP
• Customs filing on ICEGATE

Practical benefit of this lane

• Vietnam is a meaningful market for HS 330741 and already appears among the world’s importers of this product.
• India is the top global exporter of HS 330741, so you have a strong supply-positioning advantage.
• If you can support preferential origin, the duty can potentially be reduced versus the MFN rate.

Important note on the 9% rate

The 9% preferential duty is not automatic. It depends on:

• the exact preferential arrangement applicable,
• the product’s origin qualification,
• and correct origin documentation.

If you want, I can next give you:

1. a shipment document checklist for India → Vietnam, or

2. a sample invoice/packing list wording for HS 330741, or

3. a duty calculation on a specific FOB value.
