Use Of Products: LabChem products are integral parts for a variety of applications and processes. However, they are not intended for food, drug, or household use. All products should be handled only by qualified, trained personnel who are familiar with the potential chemical and health hazards.

Pricing: While we strive to maintain our prices, inflation can be a relentless driver. Therefore, LabChem reserves the right to change prices without notice. In particular, pricing for precious metals, rare earth materials, and petroleum related products can change rapidly. We are happy to quote current prices at any time. Prices do not include transportation or hazardous materials charges.

Special Requirements: If you cannot find your specific requirement in our catalog, please contact us. A substantial portion of our business is the manufacture of custom products (specials) – items with unique materials, testing or packaging – at prices you can afford.

Shipping: We endeavor to ship most catalog items to you within 24 hours, in an efficient and cost sensitive manner. In most instances, catalog items are shipped via FedEx, UPS, or a carrier of your designation. Larger shipments or shipments containing multiple hazards usually travel via LTL freight. Transportation charges will be prepaid and added to the invoice as a separate line item.

Shipment Of Hazardous Materials: FedEx, UPS, and other air carriers have strict regulations and limitations concerning acceptable quantities. Carriers typically impose a surcharge on items considered hazardous by DOT. A special packaging charge will also be added for certain hazardous items shipped by FedEx, UPS, or by air. This packaging is necessary to conform to DOT, IATA, and/or carrier-specific requirements.

Transportation: FOB LabChem Inc UPS/FedEx Prepay and Add LTL Freight Collect or Prepay and Add

Terms: Net 30 days. We gladly accept VISA, MasterCard, and American Express. LabChem only sells and ships to qualified customers.
