Sourcing the Rest of the List: Acids, Alkalis, Solvents, Esters and Alcohols We Supply
· HARMONY TECHNOLOGY (ZHEJIANG) CO., LTD.
The short answer: the group’s supply list is wider than the gas and chloromethane lines. What follows is grouped by what actually decides the purchase — the state at ambient temperature, the packaging it allows, and the hazard class it carries.

| Butyl glycol acetate (EGBEA) / diethylene glycol butyl ether acetate (DCAC) | industrial coatings, printing and cleaning formulations | closed-head drums, IBCs |
| Toluene / xylene | solvent, extraction, process diluent | closed-head drums, IBCs, ISO tank |

Alcohols, glycols and ethers
| Product | Typical use | Packaging |
|---|---|---|
| n-Butanol | coatings, esters, plasticisers | closed-head drums, IBCs, ISO tank |
| 1,2-Propanediol (propylene glycol) | heat-transfer fluid, antifreeze, industrial formulation | closed-head drums, IBCs |

| Diethylene glycol butyl ether acetate | coating and cleaning formulations | closed-head drums, IBCs |
Alkalis and inorganics
| Product | Typical use | Packaging |
|---|---|---|
| Liquid caustic soda (32 % class) | pulp, water treatment, chemical processing | IBCs, ISO tank |

The two acids that are domestic-market only
Hydrochloric acid and sulfuric acid are supplied in the domestic market, not as an export line. They are stated here rather than left off the page because a buyer who has seen them in a Chinese supplier directory will ask — and an answer that arrives at the quotation stage is worse than one that arrives before the enquiry is written.
What an enquiry for these products has to carry
| Item | Why it decides the quote |
|---|---|
| Exact product name or CAS | “Solvent” and “caustic” are not products; concentration or grade has to be stated |
| Concentration / assay | Caustic at 32 % and flake caustic are different supply chains |
| Packaging preference | Drum, IBC, ISO tank or bag — it changes the price per tonne |
| Order quantity and frequency | Decides whether the shipment is consolidated or dedicated |
| Destination and end use | Drives the document set and any import requirement at the destination |
What we can provide
These products are quoted by exact product name or CAS, with concentration, packaging and net weight per unit stated on the quotation — and the document set for the route listed rather than implied. Several lines share packaging and documentation, so a multi-line enquiry usually returns a more usable answer than a single-line one.
Who contracts and ships: every shipment is contracted, invoiced and shipped by the group operating company named on the quotation and on the documents for that shipment. This page is the group’s technical reference material.
