4. Delays: We shall not be liable for any loss, damage or penalty as a result of any delay in or failure to synthesize, deliver or otherwise perform hereunder due to any cause beyond our reasonable control, including, without limitation, unsuccessful reactions, act of Buyer, embargo or other governmental act, regulation or request affecting our business, fire, explosion, accident, theft, vandalism, riot, acts of war, strikes or other labor difficulties, lightning, flood, windstorm or other acts of God, delay in transportation, or inability to obtain necessary labor, fuel, materials, supplies or power at current prices.

5. Cancellations and Modifications: Orders, once placed, can be changed only through a written agreement between the Buyer and the Seller that clearly states the change in price or delivery timeline. An order cannot be cancelled by the Buyer unless the Seller agrees to it in writing. A 30% restocking fee applies to all cancelled orders and the buyer agrees to pay the same. The restocking fee will be subject to the same late fees as a regular payment if not paid within the stipulated time agreed to between both buyer and seller. Only orders that are cancelled within 24 hours and replaced immediately to accommodate a price correction are exempt from the above.

6. Credits and Refunds: At our discretion, we may issue a product credit or refund for the product value and shipping charges. No product credit shall be available for use if a past due balance is outstanding on the account. Any product credit is valid only for 6 months from the date of issue.

7. Payments: Unless otherwise specified in a written quotation we provide to you or written contract between the parties, goods will be billed at the price in effect at the time shipment is made. Such prices shall be subject to change without notice. Terms of sale are net 30 days (for our regular US clients) from date of invoice, in U.S. Dollars. If you default in making any payment to us when due we, at our option and without prejudice to our other lawful remedies, may defer delivery or cancel the Contract. A late fee of US $ 150 is applicable on late payments. We, at our discretion, may increase this late fee if the payment is past due for 30 days or more. If you provide a purchase order number which proves to be erroneous or invalid, you agree to pay the invoice(s) upon receipt of a "proof of delivery" and/or a "proof of shipment" signed and executed bill of lading/air bill from us. Unless specified otherwise in a written quotation that we provide to you or written contract between the parties, goods will be billed at the price in effect at the time shipment is made. Such prices changes will be automatically applied to the invoice.

Taxes and Other Charges: Any use tax, sales tax, excise tax, duty, inspection or testing fee, or any other tax, fee or charge imposed by any governmental authority, on or measured by the transaction between us shall be paid by you in addition to the prices quoted or invoiced.
