01 / THE OPPORTUNITY
A certificate supporting a claim.
Form E is a certificate of origin used under the ASEAN–China Free Trade Area (ACFTA). It can support a claim for reduced or exempt import duty when the goods and the claim meet the applicable requirements. It is not a blanket exemption for everything bought from China. DFT: ACFTA overview ↓
For an importer, the useful question is not simply “Can my supplier provide Form E?” Ask whether the certificate, product and transaction support the treatment you intend to claim. Start that discussion before agreeing a landed-cost budget.
A shipment leaving a Chinese port does not, by itself, establish that the goods qualify as originating under ACFTA.
02 / CHECK THE GOODS FIRST
Origin depends on the applicable rule.
The origin rules consider how goods are obtained or produced. Depending on the product, qualifying requirements can involve originating materials, regional value content, a change in tariff classification or a product-specific rule. The relevant rule must be checked for the actual goods. ACFTA rules of origin ↓
Give your specialist a clear description, material, function and proposed HS code. A supplier’s code is a starting point for review. Do not choose a code just because it appears to offer a lower rate.
Ask about the production background early, especially when buying through a trading company. Knowing who issues the invoice and who manufactures the goods helps organise the evidence and follow-up questions.
03 / BEFORE THE SHIPMENT
Review the documents as one story.
Share a draft where available, together with the related commercial documents. This preparation checklist helps the team spot questions; it does not replace the official certification requirements.
| Check | Prepare for the review |
|---|---|
| The product | Description, model, composition and intended use. Identify each product separately when a shipment contains several items. |
| The parties | Explain the relationship between manufacturer, exporter, invoice issuer and importer. Flag a third-country invoicing arrangement. |
| The transaction | Provide the invoice and packing list. Highlight differing quantities, units, references or descriptions rather than leaving them unexplained. |
| The origin evidence | Share the Form E draft or issued version and available supporting information. Identify which certificate item relates to each invoice item. |
| The route | Provide transport documents and details of transit or transshipment so the applicable consignment conditions can be checked. |
| The timing | Tell us when the goods ship, when they arrive and when the certificate will be available. Raise a missing or corrected certificate immediately. |
04 / START THE CONVERSATION
Five useful questions for your supplier.
- Can you arrange the appropriate origin certificate for these specific products?
- Which origin criterion supports the goods, and what production information is available?
- Can you share a draft before the final certificate is issued?
- Will the exporter, manufacturer and invoice issuer be different companies?
- Who will coordinate any corrections, and when can we expect the documents?
Keep the answers with your shipment file. If the product, supplier or manufacturing arrangement changes, ask again rather than assuming that a previous shipment settles the next one.
05 / PLAN THE COST
See the difference without assuming the rate.
Compare the applicable standard and preferential duty rates after classification and eligibility have been reviewed. A preferential rate may reduce duty; it is not automatically zero.
Illustration only: two duty scenarios
Assume a customs value of THB 100,000. The rates below are invented solely to explain the calculation, not a quotation for any product.
- Standard duty, assumed 10%
- THB 10,000
- Preferential duty, assumed 0%
- THB 0
- Difference in import duty
- THB 10,000
This compares duty only. It excludes VAT, other taxes and logistics charges. It assumes the preferential claim is eligible and accepted.
Keep an alternative budget for the applicable non-preferential treatment until the claim is confirmed. Form E does not replace a separate check of other taxes, permits and import requirements.
Understand the different import cost components ↗06 / RESOLVE QUESTIONS EARLY
A discrepancy needs context.
Different companies on the documents
Trading arrangements may involve more than one company. Explain who sells, invoices and exports. Third-party invoicing has specific requirements; ask the team to review the arrangement instead of assuming either acceptance or rejection. Official Form E notes ↓
Different descriptions or quantities
A model name on one document and a generic description on another can be difficult to connect. Provide a product mapping and explain package units. Do not alter an issued certificate yourself; raise any correction with the supplier and issuing process.
A route change or late document
Tell the team promptly if transit arrangements change or the certificate is delayed. The correct next step depends on the circumstances and applicable procedures. Do not assume that a later certificate guarantees a refund.
07 / COMMON QUESTIONS
Before you rely on the saving.
Does every Chinese product qualify?
No. The goods must satisfy the relevant origin and other requirements. The supplier’s location alone is not sufficient.
Can Form E remove all import charges?
No. Its role is preferential duty treatment. Other taxes and charges must be assessed separately.
Can I use the same certificate for another shipment?
Do not assume so. Send the evidence for the actual shipment for review; a previous successful claim is useful background, not automatic approval for the next import.
What should I send Seabra first?
Start with your product details, invoice or draft invoice, proposed route and any available Form E. Explain what is missing and your expected shipping date.
Check the claim before you count the saving.
Our customs specialists can review the goods and available evidence with you, then explain what needs clarification.
