Terms and Conditions of Sale and Warranty 

1. Application and Scope: 
The  terms  and  conditions  contained  herein  apply  to  proposals  made,  and  to  purchase  orders  received,  by  HOFFMANN  MACHINE 
COMPANY,  INC.  (hereinafter  called  “Seller”),  and  sets  forth  the  entire  agreement  between  the  parties  hereto,  and  supersedes  all 
communication,  representations  or  agreements,  whether  oral  or  written,  between  the  parties  hereto  with  respect  to  the  subject 
matter herein, and no agreement or understanding varying or extending the terms or conditions hereof will be binding unless expressly 
agreed to in writing by Seller. No conditions stated by Buyer in its purchase order or orders shall be binding upon Seller if in conflict 
with,  inconsistent  with,  or  in  addition  to,  the  terms  and  conditions  contained  herein,  unless  expressly  accepted  in  writing  by  Seller. 
Seller’s failure to object to any provision contained in any communication or purchase order from Buyer shall not be deemed a waiver 
of the terms and conditions herein. All orders or contracts are subject to approval and acceptance by Seller at its main office in North 
Carolina. These Terms and Conditions are within the sole discretion of Seller and are subject to change with or without prior notice. 
 
2. Quotations and F.O.B. Point: 
Prices  are  quoted  and  all  sales  are  made  F.O.B.  Sellers  facility  and,  unless  otherwise  indicated  in  the  proposal,  prices  quoted  are 
effective for a maximum thirty (30) days after the date of any proposal. 
 
3. Terms of Payment: 
All invoices are due and payable as set forth on the front of the invoice. Each delivery shall be considered a separate and independent 
transaction and payment thereof shall be made on terms set forth on invoice covering same. If delivery is delayed by Buyer, payment 
shall become due when Seller is prepared to make delivery. If, in the sole judgment of the Seller, the financial condition of Buyer at any 
time does not justify continuation of manufacture or of delivery as originally specified, Seller may vary terms of payment by requiring 
full or partial payment in advance, or otherwise, or may ship to Buyer’s order against sight draft with bill of lading attached.  
If  payment  is  not  received  on  or  before  payment  due  date  and  as  set  forth  in  terms  on  proposal  and/or  invoice,  or  if  payment  is 
delayed, or if payment amount is reduced, seller reserves the right to reduce or revoke equipment warranty, at seller’s sole  discretion. 
Eventual  payment  of  outstanding  amount  does  not  automatically  reinstate  warranty.  Warranty  can  only  be  reinstated  by  seller  and 
reinstatement must be confirmed by seller in writing to be valid. 
 
4. Taxes: 
Unless the quotation expressly provides otherwise, the amount of any present or future Federal, State or local sales, excise or other tax 
applicable  to  the  products  purchased  hereunder,  or  to  the  manufacture  or  sale  thereof  (including,  without  limitation,  state  or  local 
privilege or excise taxes based on gross revenue), and any taxes or amounts in lieu thereof paid or payable by Seller in respect of the 
foregoing (excluding, however, taxes based on net income), shall be added to the purchase prices and shall be paid by Buyer.  In lieu 
thereof, Buyer may provide Seller with an appropriate tax exemption certificate acceptable to the taxing authorities. 
 
5. Warranty: 
The products covered herein are warranted, for a period of twelve (12) months from date of shipment, against defects in material and 
workmanship under normal use and service by Buyer.  The liability of Seller under its warranty is limited to adjustment, in accordance 
with the Warranty Adjustment Terms set forth below, for products which are found to be defective by Seller in the form in which they 
were originally shipped. In no event will Seller be liable for collateral, consequential or other damages of any kind. 
Parts  replaced  under  Warranty  are  covered  for  a  period  of  six  (6)  months  from  the  date  of  shipment,  unless  otherwise  specified  on 
invoice, subject to the warranty adjustment terms set forth below.

PARTICULAR PURPOSE. 
 

6. Warranty Adjustment Terms: 
(a)  Adjustments  will  be  limited  to  claims  which  are  presented  promptly  after  the  product  is  found  to  be  defective,  and  within  the 
aforesaid warranty period. 
(b) All products claimed to be defective will be subject to inspection and test by Seller. Normally, Seller will request return of products 
for inspection and test, however, Seller reserves the right to make inspection and test on Buyer’s premises. Returns are to be made 
only as and if authorized in writing by Seller. 
(c)  Buyer  will  pay  all  packaging,  inspection,  labor  and  transportation  costs  involved.  Credit  for  the  transportation  costs  only  will  be 
issued by Seller provided adjustment subsequently is allowed.

accident or negligence in use, storage, transportation or handling; nor for products on which original identification markings have been 
removed, defaced or altered.
