In short

What to do if your goods fall in Appendix II

Trade and import are both barred — check by CAS number, not HS code. Only research, testing, healthcare and defence uses remain, under separate decrees.

Most codes in this appendix do not exist in the Vietnamese tariff

The appendix uses the nomenclature of the Chemical Weapons Convention list rather than the Vietnamese tariff: 7 of its 10 codes (2931.9080, 2931.9020, 2930.9099, 2921.1999, 2931.00, 3002.90 and 6-digit 2930.90) return nothing in the Vietnamese tariff — the real corresponding lines are 29319090, 29309090, 29211900 and 30029000. Consignments must therefore be checked by CAS number, not HS code. Two codes do match but are broader than the ban: 2524.90.00 also covers chrysotile asbestos (not among the banned amphiboles), and 2904.10.00 covers all sulphonated hydrocarbon derivatives.

For a substance actually on the list, both trade and import are barred

Where the consignment genuinely is a listed substance (checked by CAS number), the ban bites at two levels at once: Article 6.1(b) of the Law on Investment prohibits TRADE, and Decree 292/2026/ND-CP Appendix I Section II item 3 places it among import-PROHIBITED goods (item 22 for amphibole asbestos specifically). There is no commercial import licence to apply for.

Research, testing, healthcare and defence follow separate decrees

Article 6.2 of the Law on Investment preserves a route for producing and using these substances in analysis, testing, scientific research, healthcare, pharmaceutical manufacture, crime investigation and defence or security — "as prescribed by the Government". It is a purpose-based exception requiring the relevant sector decree; the Law itself sets out no procedure.

Grouped by tariff chapter. An 8-digit code applies to that code alone; a line covering a whole heading is marked separately. A line with no code is a heading row of the appendix — this page does not assign codes. Select a code to open the full HS lookup.

Scope & how to read the table

What decides whether your goods are in it

THE LIST IS KEYED ON CAS NUMBER AND SUBSTANCE NAME, NOT ON THE HS CODE — the table prints a separate CAS column, and 7 of the appendix’s 10 codes DO NOT EXIST in the Vietnamese import-export nomenclature. The appendix copies its codes in the Combined-Nomenclature style used for the Chemical Weapons Convention Schedule 1 list (written 4+4 with a single dot and endings 80/99/20, e.g. 2931.9080), unlike Vietnam’s 4+2+2 split; looking up 2931.9080, 2931.9020, 2930.9099, 2921.1999, 2931.00 or 3002.90 in the Vietnamese tariff returns nothing, the actual corresponding lines being 29319090, 29309090, 29211900 and 30029000. The three codes that do match — 2524.10.00, 2524.90.00 and 2904.10.00 — are precisely those written in Vietnamese format, and the latter two are BROADER than the ban: 2524.90.00 "Asbestos - Other" also covers serpentine-group chrysotile, which is not among the amphiboles banned here, while 2904.10.00 covers all sulphonated hydrocarbon derivatives, not only DBSA. Article 6.1(b) of the Law on Investment: "The following investment and business activities are prohibited: […] (b) dealing in the chemicals and minerals listed in Appendix II to this Law." At the customs layer, Decree 292/2026/ND-CP (issued 22 July 2026, effective 5 September 2026, replacing Decree 69/2018/ND-CP), Appendix I Section II item 3 lists "Hazardous chemicals specified in the list of banned chemicals and minerals issued under the Law on Investment" as import-prohibited goods managed by the Ministry of Industry and Trade; item 22 separately lists "Products and materials containing amphibole asbestos", managed by the Ministry of Construction. Article 6.2 of the Law: production and use of these products for analysis, testing, scientific research, healthcare, pharmaceutical manufacture, crime investigation and defence or security follows Government regulations.

What being absent from this list does not mean

This appendix is one of many specialised-management lists. Goods absent from it may still fall under another ministry's list, or be controlled on other conditions. This page does not replace a full check before filing.

FAQ

Frequently asked questions about Appendix II 143/2025/QH15

Which goods does Appendix II of 143/2025/QH15 cover?
Appendix II of the Law on Investment — the list of banned chemicals and minerals, 44 table lines grouped under 18 serial numbers. The first thirteen are Chemical Weapons Convention Schedule 1 agents: organophosphorus compounds of the sarin, soman and tabun families; sulphur mustards and their derivatives; Lewisite compounds; nitrogen mustards HN1, HN2 and HN3; the toxins saxitoxin and ricin; the precursors DF, QL, chlorosarin and chlorosoman; and dodecylbenzenesulphonic acid (DBSA). The last five are amphibole asbestos: crocidolite, amosite, anthophyllite, actinolite and tremolite. The table carries a CAS number column alongside the HS code column.
How do I tell whether my goods fall in Appendix II of 143/2025/QH15?
THE LIST IS KEYED ON CAS NUMBER AND SUBSTANCE NAME, NOT ON THE HS CODE — the table prints a separate CAS column, and 7 of the appendix’s 10 codes DO NOT EXIST in the Vietnamese import-export nomenclature.

At the customs layer, Decree 292/2026/ND-CP (issued 22 July 2026, effective 5 September 2026, replacing Decree 69/2018/ND-CP), Appendix I Section II item 3 lists "Hazardous chemicals specified in the list of banned chemicals and minerals issued under the Law on Investment" as import-prohibited goods managed by the Ministry of Industry and Trade; item 22 separately lists "Products and materials containing amphibole asbestos", managed by the Ministry of Construction.

What does import prohibited involve?
1. There is no commercial import procedure to follow: goods on this list are both barred from trade by Article 6.1(b) of the Law on Investment and named in the import-prohibited list of Decree 292/2026/ND-CP. Article 6.2 opens a route only for PRODUCTION and USE in analysis, testing, scientific research, healthcare, pharmaceutical manufacture, crime investigation and defence or security — and leaves the detail to Government regulation, so the sector decree for each purpose must be checked; there is no single counter. — Ministry of Industry and Trade for the chemicals (Decree 292/2026/ND-CP, Appendix I Section II item 3); Ministry of Construction for products and materials containing amphibole asbestos (item 22 of the same appendix)
