The monosodium glutamate (MSG) import procedure is a food additive category with a legal characteristic that very few other food items encounter: this product is currently subject to a specific anti-dumping duty on goods originating from China and Indonesia. This is what makes correctly determining the country of origin a make-or-break factor throughout the entire import process, alongside the standard product declaration and food safety obligations.
Not every business fully understands the monosodium glutamate import procedure, especially the need to check the current anti-dumping duty review decision before signing a contract with a Chinese or Indonesian supplier. An error in determining origin, or overlooking the product self-declaration file, can result in businesses paying unexpected anti-dumping duty or facing clearance delays.
In this article, 3W Logistics presents the complete monosodium glutamate import procedure under the latest legal regulations and tariff schedule — from legal conditions, HS codes, tax calculation, and required documentation, through the step-by-step process and practical risks, from the perspective of a forwarder experienced in handling imported food additives.
1. Legal conditions for importing MSG
Monosodium Glutamate (MSG) is not on the list of prohibited import goods; it is a food additive on the list permitted for use under Ministry of Health regulations, so the monosodium glutamate import procedure follows the product self-declaration mechanism rather than requiring a more complex registered declaration.
| Condition | Detailed Content |
|---|---|
| Product self-declaration | Under Decree 15/2018/ND-CP, MSG is a food additive on the permitted-use list for its intended purpose, so it follows the product self-declaration procedure, based on a Food Safety Test Result Certificate |
| Anti-dumping duty | MSG originating from China and Indonesia is currently subject to anti-dumping duty under case AD09 of the Ministry of Industry and Trade; the duty rate is reviewed periodically, so businesses need to check the latest review decision at the time of import |
| Food safety inspection | State food safety inspection is carried out upon import, following either the standard or reduced inspection method depending on the business’s compliance history |
| Product labeling | A Vietnamese supplementary label under Decree 43/2017/ND-CP (as amended by Decree 111/2021/ND-CP): product name, ingredients, shelf life, importer name and address |
Practical note: The biggest difference in the monosodium glutamate import procedure compared to other food additives lies in the origin verification step. Since the AD09 anti-dumping investigation was initiated in 2019 at the request of domestic manufacturers, MSG imported from China and Indonesia has been and continues to be subject to a per-tonne anti-dumping duty, reviewed periodically by the Ministry of Industry and Trade, with the rate potentially adjusted at each review. Businesses importing from these two markets must update themselves on the current review decision before signing a contract, to avoid unexpected added costs.
2. HS code and import tax for MSG
MSG falls under heading 29.22 (Oxygen-function amino-compounds) in the Import-Export Tariff Schedule, specifically the subheading dedicated to glutamic acid and its salts.
| Heading/HS Code | Detailed Description | Import Tax (MFN) |
|---|---|---|
| 29.22 — Oxygen-function amino-compounds | ||
| 2922.42.20 | Monosodium Glutamate (MSG) — the single HS code used for importing MSG, and also the code subject to anti-dumping duty on goods from China and Indonesia | 5–15% |
Important note on HS codes and tax: MSG has only one single HS code, 2922.42.20, not divided into smaller subheadings as with many other goods, so the risk of an incorrect HS code is practically negligible. What businesses need to pay particular attention to is the standard (MFN) import tax rate applicable to this code, plus the per-tonne anti-dumping duty if the goods originate from China or Indonesia — this anti-dumping duty is independent of the MFN import tax and is added into the taxable value. For goods with a C/O from countries not subject to the anti-dumping duty (e.g. Thailand, or goods manufactured abroad, other ASEAN countries), businesses are only subject to the standard import tax. Regarding VAT, the current rate of 8% applies through December 31, 2026 under Decree 174/2025/ND-CP. In the monosodium glutamate import procedure, accurately determining the country of origin and checking the latest anti-dumping review decision is an unskippable step before calculating import costs.
3. Documentation for the monosodium glutamate import procedure
The documentation set for the monosodium glutamate import procedure requires particular attention to origin documentation, per Decree 15/2018/ND-CP and Circular 38/2015/TT-BTC (as amended by Circular 39/2018/TT-BTC).
| Document | When to Prepare | Important Note |
|---|---|---|
| Sales Contract | Before deposit | Clearly state the manufacturing country, brand, packaging specification, and terms for providing a sample and the C/O |
| Commercial Invoice & Packing List | Before goods are shipped | Clearly state the weight in tonnes/kg, serving as the basis for calculating anti-dumping duty if applicable |
| Bill of Lading | After goods are loaded onto the vessel | MSG is typically packed in 25kg or 50kg bags, loaded in dry containers; moisture protection is needed throughout the journey |
| Food Safety Test Result Certificate | Before the main shipment arrives; send a sample in advance | Serves as the basis for preparing the product self-declaration file; should be completed before the main shipment officially arrives at port |
| Product self-declaration form | Before goods arrive at port | Submitted via the National Single Window Portal; once approved, it must be publicly posted for 15 days |
| C/O (Certificate of Origin) | Before goods are shipped | Particularly important for determining whether the shipment is subject to anti-dumping duty (China, Indonesia) |
| Electronic customs declaration (VNACCS/VCIS) | Once documentation is complete | Declare HS code 2922.42.20 correctly, and clearly declare the country of origin so customs can correctly calculate anti-dumping duty if applicable |
4. Step-by-step monosodium glutamate import procedure
Step 1: Check the country of origin and anti-dumping duty status
Determine the manufacturing country of the intended shipment, and cross-check against the Ministry of Industry and Trade’s current anti-dumping review decision to accurately estimate total tax cost if the goods source from China or Indonesia.
Step 2: Import a product sample in advance and test it
Send an MSG sample to Vietnam, test it at a licensed center to obtain the Food Safety Test Result Certificate, serving as the basis for preparing the product self-declaration file.
Step 3: Prepare and submit the product self-declaration form
Based on the test results, prepare the product self-declaration file together with a label sample, submit it via the National Single Window Portal, and wait for confirmation before the main shipment officially arrives.
Step 4: Negotiate the contract and require a C/O
Sign the MSG purchase contract, clearly stating the manufacturing country and weight, and require a C/O in the contract terms to prove origin, serving as the basis for correctly applying import tax and anti-dumping duty (if applicable).
Step 5: Transport goods to a Vietnamese port and file customs declaration
Transport the goods via dry container, ensuring moisture protection. File the VNACCS/VCIS declaration with the full HS code, self-declaration number, C/O, and clearly declared country of origin so customs can correctly calculate the taxes.
Step 6: Pay tax, clear customs, and apply labeling
After fulfilling the tax obligation (including anti-dumping duty if applicable) and receiving a passing food safety inspection result, the goods are cleared. Complete the Vietnamese supplementary labeling, receive the goods, and keep complete documentation on file to support post-clearance inspection.
5. How to calculate import tax on monosodium glutamate import procedure
MSG is not subject to special consumption tax; it is subject to import tax, VAT, and potentially anti-dumping duty depending on origin. As an example, for a 20-tonne MSG shipment with a CIF price of VND 600 million, comparing the case of importing from China (subject to anti-dumping duty) versus a country not subject to it:
| Tax / Cost Item | Chinese origin (subject to anti-dumping duty) | Other origin (not subject to anti-dumping duty) |
|---|---|---|
| CIF price | VND 600,000,000 | VND 600,000,000 |
| Import tax (MFN 10%) | 10% × 600M = VND 60,000,000 | 10% × 600M = VND 60,000,000 |
| Anti-dumping duty | Per-tonne rate × 20 tonnes per the current review decision — the specific rate must be looked up | VND 0 (not subject to it) |
| VAT (8%, applicable through end of 2026) | 8% × (CIF + import tax + anti-dumping duty) | 8% × (600+60)M = VND 52,800,000 |
| Note | The anti-dumping duty rate changes with each Ministry of Industry and Trade review and is calculated per tonne (not as a percentage rate); businesses need to check the latest review decision before importing from China or Indonesia to get an accurate figure. | |
From 3W Logistics’ practical experience: With MSG, the most common mistake we see in the MSG import procedure is businesses locking in a price with a Chinese supplier without factoring in the per-tonne anti-dumping duty — this duty is independent of the MFN import tax and can inflate cost significantly compared to the original budget. Carefully checking the current review decision and considering alternative sourcing from markets not subject to the duty before negotiating price helps businesses plan import costs more proactively. — Ms. Apple, CCO, 3W Logistics
6. Common risks in the monosodium glutamate import procedure
| Risk | Manifestation | Prevention |
|---|---|---|
| Overlooking anti-dumping duty when calculating cost | Locking in an import price from China/Indonesia without adding the anti-dumping duty, resulting in inflated cost at clearance | Check the Ministry of Industry and Trade’s current anti-dumping review decision before negotiating price with the supplier |
| Misdeclared or missing C/O proving origin | No clear C/O makes it difficult for customs to determine whether the shipment is subject to anti-dumping duty, potentially resulting in a less favorable tax rate | Require the supplier to issue a complete, clear C/O matching the actual manufacturing country |
| Preparing the self-declaration too late | Waiting until the goods arrive to prepare the self-declaration file, resulting in container and yard demurrage while waiting for results | Import a product sample to Vietnam and complete the self-declaration before the main shipment is exported |
| Failing food safety criteria | The product fails purity or impurity requirements during inspection, resulting in denied clearance | Choose a reputable supplier with clear quality certification from the manufacturing plant |
| Product label missing mandatory information | Missing ingredients or shelf life on the Vietnamese supplementary label — customs holds the goods and requires supplementary labeling at port | Prepare a complete supplementary label sample under Decree 43/2017/ND-CP and 111/2021/ND-CP before the goods arrive at port |
FAQ – Frequently asked questions about the MSG import procedure
Question 1: What documents are required for the monosodium glutamate import procedure?
The complete documentation set for the MSG import procedure includes: Sales Contract; Commercial Invoice and Packing List; Bill of Lading; Food Safety Test Result Certificate; product self-declaration form; C/O; electronic customs declaration (VNACCS/VCIS). The C/O is particularly important for determining whether the shipment is subject to anti-dumping duty.
Question 2: MSG imported from which countries is subject to anti-dumping duty?
Only MSG originating from China and Indonesia is subject to anti-dumping duty under case AD09, investigated and applied by the Ministry of Industry and Trade. MSG from other sources is not subject to this. This is an important point to understand when carrying out the MSG import procedure, since the rate is reviewed periodically and may change.
Question 3: How many types of tax must be paid when importing MSG?
MSG is subject to up to three types of tax: (1) Import tax calculated on the CIF price at the MFN rate; (2) Anti-dumping duty calculated per tonne, applicable only to goods of Chinese or Indonesian origin; (3) VAT, currently 8% and applicable through December 31, 2026 under Decree 174/2025/ND-CP. MSG is not subject to special consumption tax.
Question 4: How long does the MSG import procedure take?
The total time from sample testing to customs clearance is typically 25-35 days, including the product self-declaration time (about 10-15 days) plus shipping and food safety inspection time at port. For goods of Chinese or Indonesian origin, additional time is needed to verify and calculate the anti-dumping duty.
