Customs 101: Clearing Thai-Origin Goods into India without Hassle

If you’ve ever had a shipment arrive on time but still lose days (and money) in customs, you already know the truth: clearance is won or lost before the vessel even sails.

For Thai-origin goods entering India, the “no-hassle” playbook is simple:

1. Classify correctly (HS code + policy checks)

2. Prepare a clean, consistent document set

3. Get origin + direct consignment right (especially if claiming preferential duty)

4. Digitize early (so your Bill of Entry doesn’t get stuck in document queries)

Here’s a practical, step-by-step guide to make Thailand → India import clearance predictable.

---

1) Start with the right commercial setup

Before you talk rates or ETAs, lock these in:

Decide who is the Importer of Record (IOR)

The IOR is the party responsible for:

• Filing the Bill of Entry (usually via a customs broker/CHA)

• Declaring classification, value, origin

• Paying duties/taxes and meeting compliance requirements

If your buyer in India is the IOR, align on who provides which documents and who bears clearance risk.

Choose Incoterms that match your control level

• FOB/CFR/CIF: buyer typically controls Indian customs (common for B2B)

• DAP/DDP: seller controls more, but DDP in India can be operationally tricky if you don’t have strong local capability

Appoint a capable customs broker (CHA)

Even with digitization, clearance is still execution-heavy. A good broker:

• Pre-checks classification and import policy

• Manages online filings and document uploads

• Pre-empts “routine” queries (valuation, catalogues, technical specs)

---

2) Nail HS classification and “import policy” early

This is where most preventable delays begin.

Do a pre-classification (before booking space)

For each SKU (or at least each product family):

• Confirm HS code at 8 digits for India imports

• Confirm duty structure and any cess/surcharges

• Check if your product is under restricted category or needs licenses/NOCs

Watch for “silent” compliance triggers

Depending on your goods, you may need partner-agency clearances (examples include food, chemicals, electronics, wireless devices, plant/animal products). If this applies, build time for:

• Testing or registration

• Labeling rules

• Product approvals or import permits

Tip: If your product has variants, lock the HS code logic once and apply consistently-changing classification shipment to shipment attracts scrutiny.

3) Thai-origin + preferential duty: get origin right (or don’t claim it)

If your goods truly qualify as Thai-origin under the applicable trade arrangement, preferential duty can reduce landed cost. But if you claim preference without being “audit-ready,” you risk:

• Preferential benefit being denied

• Extra duty demand and penalties

• Clearance delays from origin verification queries

Understand “proof of origin” (not just a stamp)

India’s rules place responsibility on the importer claiming preferential duty to:

• Declare that goods qualify as originating

• Possess sufficient information on how origin criteria are met

• Exercise reasonable care in what they submit

In practice: don’t treat origin paperwork as a last-minute add-on. Treat it like a compliance file.

Form AI (common in ASEAN-India preference claims)

For ASEAN–India preferential treatment, the proof of origin often comes in a structured format (commonly referred to as Form AI). Treat it like a sensitive document:

• Names/addresses must match commercial documents

• HS code and product description must match invoice/packing list

• Origin criterion must be correctly stated

Direct consignment matters (especially with transshipment)

Even if goods are Thai-origin, preferential treatment usually expects the shipment to be consigned directly per the agreement’s rules. If you route via a hub port (which is common), ensure you can prove:

• The goods remained under customs control in transit

• No processing occurred in the transit country (beyond permitted handling)

• Shipping documentation supports continuity (e.g., through transport evidence)

Rule of thumb: If you can’t document the routing cleanly, either fix the routing documentation-or don’t claim preference.

4) Build a “customs-ready” document pack (clean, consistent, digital)

A shipment can be physically perfect and still get held for one reason: documents don’t align.

Core clearance documents (typical)

• Commercial Invoice

• Packing List

• Bill of Lading (or Sea Waybill, where applicable)

• Insurance (if relevant to valuation / Incoterms)

• Product literature/catalogues/technical specs (highly useful for queries)

• Proof of origin (only if claiming preferential duty)

Consistency checks that prevent queries

Before you hand docs to your broker, verify:

• Consignee/Importer names match across all documents

• HS code is consistent (invoice + COO/proof of origin + broker declaration)

• Quantity & UOM match packing list vs invoice

• Gross weight / net weight make sense (no “impossible” ratios)

• Currency, unit price, totals reconcile perfectly

• Country of origin is stated consistently

---

5) Digitization: win the time game with e‑documents

India customs clearance is heavily digitized. If your docs aren’t upload-ready, you lose time.

Plan for online filing + online document submission

Your broker will typically file electronically and submit supporting documents digitally. To avoid upload issues:

• Keep scans sharp and readable

• Use consistent file naming (Invoice_123, PL_123, BL_123, COO_123, etc.)

• Avoid huge file sizes; compress PDFs properly

Pro tip: Ask your broker for their “document naming + size” rules and follow them every time.

6) The real clearance flow: what happens after arrival

Here’s how it usually plays out operationally:

1. Manifest/arrival data is filed

2. Bill of Entry is filed (with declarations, classification, valuation, origin, etc.)

3. Assessment happens (often digitally; may involve queries)

4. Duty payment

5. Examination (if selected) and/or facilitated clearance

6. Out of Charge (customs release)

7. Delivery + inland movement

Why some shipments clear fast and others don’t

Speed is driven by:

• Whether the shipment is facilitated or selected for checks

• Whether the file triggers valuation/classification/origin questions

• Whether partner-agency requirements apply

• How quickly you respond to queries with clean supporting documents

---

7) Costs: beyond duty-what blows up budgets

Customs duty is only one bucket

Your landed cost typically includes:

• Customs duty components (varies by HS and policy)

• Port/terminal charges and handling

• Customs broker fees

• Examination and scanning fees (if applicable)

• Inland transport

• Storage/demurrage/detention (the big “avoidable” costs)

The most avoidable charges

• Demurrage / detention from clearance delays

• Storage from document mismatches

• Rework fees from amendments and late corrections

Best practice: Treat “free time” like cash. Track it daily once the vessel arrives.

8) Common delay triggers (and how to prevent each)

1) HS code disputes

Prevent it: pre-classify + keep technical literature ready.

2) Valuation questions (discounts, assists, related-party concerns)

Prevent it: ensure invoice terms are clear; keep price lists/POs/contracts handy.

3) Origin preference claimed without full support

Prevent it: claim preferential duty only when your origin story is defensible end-to-end.

4) Transshipment without clean “direct consignment” evidence

Prevent it: confirm routing documents before shipping, not after arrival.

5) Product compliance discovered too late

Prevent it: run a compliance check per product category and build lead time for approvals.

6) Poor digital documentation

Prevent it: maintain a standard PDF pack and reuse templates.

9) The “No‑Hassle” checklist (copy/paste for every shipment)

Before cargo pickup

• HS code confirmed (8-digit India)

• Import policy checked (restricted/licensed/NOC?)

• Preferential duty decision made (yes/no)

• Proof of origin requirements confirmed

• Transshipment route reviewed for direct-consignment compliance

• Labeling/marking requirements confirmed

Before vessel sails

• Invoice + packing list final (no draft versions floating around)

• Bill of Lading instructions approved (names, addresses, notify party)

• Product catalogue/tech specs ready for quick submission

• All documents converted to upload-ready PDFs

On arrival

• Broker has full doc pack + routing details

• Query response owner assigned (someone who can answer within hours)

• Free-time countdown tracked daily

• Inland delivery plan ready (don’t wait for OOC to book trucks)

FAQ

Should I always claim preferential duty for Thai-origin goods?

Only if you can prove origin and routing cleanly. If you’re not ready, the “savings” can evaporate into delays and disputes.

What’s the fastest way to reduce clearance time?

Pre-classification + document consistency + being able to respond to queries immediately with supporting evidence.

What’s the #1 rookie mistake?

Treating customs as a paperwork step after arrival-rather than a process you engineer before shipping.
