Chemical SDS reader for imports
Upload a chemical Safety Data Sheet (SDS/MSDS). Avenir's AI extracts the composition, CAS numbers, GHS hazard classification and suggests HS codes for both the product and each substance — preparing your chemical import declaration in seconds.
Upload your SDS file
Supports PDF, images (PNG/JPG) and Excel (.xlsx) · Up to 10MB
HS code and classification results are reference information only — they do not replace legal advice or a customs authority's classification decision. Always cross-check against the current catalogue (Decree 26/2026/NĐ-CP) before filing.

AI extracts
Recognises the 16 GHS sections and reads the composition table by CAS number and concentration.
Review & suggest
Classifies hazards and suggests HS codes for the product and each substance to prepare your declaration.
What does the tool extract from an SDS?
When importing chemicals, the SDS (Safety Data Sheet, or MSDS) is the source technical document that drives the HS code, declaration obligations and transport conditions. The tool helps you grasp the key information fast:
Composition & CAS
Substance name, CAS number (normalised), concentration %, per-substance classification (section 3).
GHS hazards
Signal word, hazard pictograms, H/P codes (section 2) — know the risk level at a glance.
HS code suggestions
Product-level HS code (with reasoning) and reference codes for each substance.
Transport & physical
UN number, IMDG class, flash point, physical state — for booking & warehousing.
Once you have suggested HS codes, you can look up HS codes & import/export duty rates, or reconcile the whole document set with the document check tool.

What does this SDS reader do?+
It extracts the chemical composition (name, CAS number, concentration %), GHS hazard classification (section 2), physical & chemical properties (section 9) and transport information (section 14) from the Safety Data Sheet, and suggests HS codes for both the product and each substance — to help prepare a chemical import declaration.
What is an SDS (MSDS) and which sections does it contain?+
An SDS (Safety Data Sheet) — also called an MSDS — is a GHS-standard document of 16 sections describing the composition, hazardous properties, first aid, physical/chemical data and transport of a chemical or mixture. It is the source technical document for determining the HS code, GHS classification and declaration obligations when importing chemicals.
What is a CAS number and how does the tool look it up?+
A CAS Number is a unique identifier assigned by the Chemical Abstracts Service to each chemical. The tool automatically normalises the CAS number (stripping leading zeros), then cross-checks it against the controlled-chemicals catalogue and suggests HS codes for each substance.
Which chemicals must be declared on import?+
Under Decree 26/2026/NĐ-CP, chemicals whose HS code falls under Chapter 28 or 29 of the import/export tariff schedule must be declared through the National Single Window before clearance, together with the SDS. The declaration obligation is based on the HS code of the imported product/mixture, not the HS code of each substance inside it.
When is a chemical import exempt from declaration?+
Under Decree 26/2026/NĐ-CP, you are exempt when: importing under 10 kg per invoice; importing under 1 kg of a new chemical for testing; or the mixture/product has an HS code outside Chapter 28/29 (even if it contains substances from those chapters). The tool does not determine quantity from the SDS, so you must check against your actual import invoice.
Do the HS suggestions replace customs classification?+
No. The HS codes and classification are for reference only, to support a quick review before declaring. The final decision rests with the customs authority; always cross-check against the current catalogue.
Which SDS file formats are supported?+
PDF, images (PNG/JPG) and Excel (.xlsx). A 16-section GHS-standard SDS gives the most accurate results.
Is my SDS data kept confidential?+
