Food preservatives are operationally sensitive import items because the applicable HS code, import duty, food safety dossier and market circulation requirements depend on the chemical identity, CAS number, food-grade status, whether the item is a single substance or a blended additive, and whether the substance is permitted for the intended food category. If the importer declares only a commercial name such as “preservative powder”, Customs and food safety authorities may request additional COA, SDS/MSDS, test reports, labelling evidence and explanations. This article provides an E2E (End-to-End) checklist for reviewing HS code, taxes, specialized policy, documents and pre-ETA risks.

Scope focus: this article covers food preservatives used as food additives. It does not automatically apply to cosmetic preservatives, industrial chemicals, disinfectants, pesticides, veterinary products or pharmaceutical ingredients.

QUICK FACT

Item	Review direction	Operational note
Product name	Food preservatives such as sodium benzoate, potassium sorbate, calcium propionate, benzoic acid, sorbic acid or preservative blends.	Avoid a generic “food additive” description where the active ingredient is available.
Reference HS codes	2916.31.00, 2916.19.00, 2915.50.00, 3824.99.70 or 3824.99.99, depending on composition and presentation.	Finalize classification based on CAS, COA, composition, single substance/blend and actual use.
Food safety dossier	Self-declaration may apply to permitted food additives; product registration must be reviewed for blended additives with new uses, additives outside the permitted list or additives not used for permitted target foods.	Do not conclude “self-declaration only” before checking INS/E-number and permitted use.
Import food safety inspection	May be subject to state food safety inspection under the Ministry of Health list.	Review Circular 15/2024/TT-BYT and the actual HS code.
VAT	Reference VAT: 10%; 8% is only reviewed if the item is not in the exclusion appendices and the VAT reduction policy is valid.	Many preservatives fall under chemical chapters and must be reviewed carefully.
C/O	Special preferential duty may apply if the C/O is valid under a relevant FTA.	C/O must match HS code, ingredient description, origin and invoice.

Legal note: food preservatives must be reviewed against the permitted additive list, permitted food categories, maximum use levels, HS code, import food safety dossier and labelling requirements. Review catalogue, SDS/MSDS, COA, test report, specification, CAS number, INS/E-number and actual import purpose.

SCOPE OF APPLICATION

Covered goods

Food-grade preservatives imported as food additives, in powder, granule, crystal, liquid or blended additive form.

Related product group

The taxonomy group includes sweeteners, preservatives, colorants, acidity regulators and anti-caking agents. This article covers preservatives only.

Excluded variants

Cosmetic preservatives, industrial preservatives, disinfectants, pesticides, feed additives and pharmaceutical ingredients may be subject to different policies.

Shipment scenarios

Commercial goods, samples, R&D imports, EPE/FDI factory imports and project shipments may require different explanations and documents.

CLASSIFICATION & TECHNICAL IDENTIFICATION

The classification of food preservatives should be based on chemical identity, CAS number, purity, food-grade status, INS/E-number, single substance or blend status, and intended food application. Avoid using only the trade name when technical documents identify sodium benzoate, potassium sorbate, calcium propionate or a preservative blend.

Criterion	Documents to check	Risk if wrong	Suggested goods description
Active ingredient/CAS	COA, specification, SDS/MSDS, test report.	Wrong HS chapter between Chapter 29 and Chapter 38.	Sodium benzoate / potassium sorbate / calcium propionate – food grade, CAS, packing.
Single substance or blend	Formula, percentage composition, technical sheet.	Misclassification as a pure chemical or as a prepared additive.	Prepared food preservative blend – main active ingredients and composition if suitable.
Food-grade status	COA, producer standard, certificate if available.	Risk of being treated as industrial chemical.	Food-grade preservative for food processing.
INS/E-number	Label, catalogue, specification.	Unable to demonstrate permitted additive use.	Include INS/E-number where officially shown.
Import purpose	Contract, PO, intended-use explanation and declaration dossier.	Risk of being treated as industrial chemical, disinfectant or non-food chemical.	Food preservative used in food manufacturing/processing; specify active ingredient and food-grade use where available.

HS CODE – DUTY – C/O

No single HS code should be applied to all preservatives. Final classification must follow chemical composition, purity, preparation and actual use. The table below is for pre-clearance review only.

Reference HS	Application condition	Reference ordinary duty	Reference MFN duty	VAT	FTA duty if C/O is valid
2916.31.00	Benzoic acid, its salts and esters; often reviewed for sodium benzoate/benzoic acid as single substances.	7.5%	5%	10%; review 8% only if eligible	May be 0% or preferential under applicable FTA.
2916.19.00	Other unsaturated acyclic monocarboxylic acids; may be reviewed for sorbic acid/potassium sorbate where appropriate.	0%	0%	Review at declaration date	Subject to C/O and FTA rules.
2915.50.00	Propionic acid, its salts and esters; may be reviewed for calcium/sodium propionate.	0%	0%	Review at declaration date	Subject to C/O and origin rules.
3824.99.70	Other chemical preparations used in food processing; often reviewed for blended preservative preparations.	9%	6%	10%; review VAT exclusion appendices	Review under the relevant FTA.
3824.99.99	Other, only where no more specific HS code applies.	0%	0%	Review at declaration date	Subject to origin rules.

Reference HS	Condition	Risk if misapplied	Documents to compare
2916.31.00	Benzoic acid/sodium benzoate in single-substance form.	Wrong tax and food safety policy.	COA, CAS, purity, SDS/MSDS.
2916.19.00	Sorbic acid/potassium sorbate if matching the legal description.	Wrong if the item is a blended additive.	Specification, composition, label.
2915.50.00	Propionic acid and salts/esters of propionic acid.	Wrong if the product contains significant carriers or anti-caking agents as a preparation.	COA, CAS, formula and manufacturing specification.
3824.99.70	Prepared chemical products used in food processing.	Confusion between chemical ingredient and additive blend.	Formula, technical sheet, intended use.

APPLICABLE SPECIALIZED POLICIES

FAQ

Do food preservatives require declaration?

Usually yes, either self-declaration or product registration depending on permitted use and additive status.

Is food safety inspection required?

It may be required if the HS code and item are listed under the Ministry of Health food safety inspection list.

Can one HS code cover all preservatives?

No. Sodium benzoate, potassium sorbate, calcium propionate and blends may fall under different HS codes.

Is VAT 8% or 10%?

Use 10% as the cautious reference if the item falls under chemical chapters/exclusions; review 8% only if eligible.

Can C/O reduce duty?

Yes, if the C/O is valid and the origin rule is satisfied.

What if COA does not show food grade?

Ask the supplier for additional specification or confirmation for food use before shipment.
