1. Check the Contract
First, examine the contract terms. In practice, whether the price changes due to rising raw material costs depends on specific clauses: Fixed-price clauses—the contract stipulates a fixed total price; the seller cannot alter the price without the buyer’s written consent and must absorb the entire cost difference.
Price adjustment clauses—provisions for negotiation or market-based adjustments when material prices fluctuate beyond a certain threshold (e.g., 5%), or direct adjustments based on agreed formulas. Practical examples—an order signed in the first half of the year based on market rates at the time (with only a small deposit paid) saw multiple material price hikes between May and August; the factory had to absorb the cost difference rather than asking the client for more money. No agreement—if the contract lacks a price adjustment mechanism, the risk of price increases falls on the party committed to the fixed price by default; the allocation of risk is determined the moment the contract is signed.
2.
Change of Circumstances
What if there is no agreement?
Under Article 533 of the Civil Code, a “change of circumstances” can be invoked when material prices skyrocket without a prior agreement: Applicability—fundamental conditions change significantly after the contract is formed due to events unforeseeable at the time of signing that do not constitute ordinary commercial risk, making continued performance manifestly unfair to one party. Procedure—the adversely affected party must first renegotiate with the other party; if no agreement is reached within a reasonable time, they may petition a court or arbitration institution to modify or terminate the contract. Adjudication—courts modify or terminate the contract based on the principle of fairness and actual circumstances. Boundaries—ordinary commercial fluctuations do not qualify; only drastic price surges or crashes resulting in manifest unfairness do. Risks—litigation is costly and time-consuming, making it a less-than-ideal option; without a price adjustment clause, you are forced to rely on negotiation or lawsuits, meaning you lack the initiative.
III. Price Linkage Clauses
How to draft price linkage clauses.
Based on industry standard contracts, clauses regarding raw material price adjustments should cover four aspects: Anchor Point—clearly specify the material type, specifications, source, and reference date (e.g., the date Party A provides written confirmation of construction drawings; medium-heavy plate at ¥X per ton); Formula—define the adjusted price (Base Price × Current Index / Base Index) and clarify whether the cost covers only the material or includes transportation and specific cost proportions; Threshold—no adjustment for price fluctuations within ±5%; amounts exceeding this range are settled based on actual purchase prices, with the same rules applying to both increases and decreases; Cycle—specify whether adjustments are monthly or quarterly and state the effective date; Basis—base adjustments on actual manufacturer invoices or publicly quoted prices recognized by both parties (with Party A retaining the right to verify); Adjustment Formula—the price adjustment amount equals (Arithmetic Mean of Construction Period Market Price – [Base Period Market Price × (1 + Risk Margin)]) × Quantity of Material Used × (1 + Tax Rate).
IV.
Buyer Price Locking
How the purchaser can lock in prices.
Based on procurement practices, here are four strategies to mitigate price hikes: Price-Locking Agreements—sign quarterly or annual agreements where the supplier absorbs raw material price fluctuations during the validity period; Floating Range Clauses—if permanent price locking isn’t feasible, specify a fluctuation range (e.g., ±5%) in the contract, with price adjustments negotiated only if the range is exceeded, thereby preventing unchecked price hikes; Comparative Pricing with Alternative Suppliers—simultaneously solicit quotes and lock-in prices from multiple suppliers, using competitors’ rock-bottom prices as leverage to pressure current partners into stabilizing their supply prices; Price Reversion Clauses—if a price hike is inevitable, negotiate phased adjustments (e.g., +3% this month, +2% next month) while stipulating that prices must drop correspondingly if material costs fall; Basis for Price Hikes—suppliers must provide 15 days’ written notice and full justification (market data, purchase records) for any price adjustment, which may only be implemented upon mutual agreement.
V.
Seller Profit Protection
How suppliers can safeguard their profit margins.
Based on industry experience, here are five strategies for manufacturers of non-standard equipment to handle price hikes: **Quote Validity**—specify an expiration date (e.g., valid for 30 days from the date of issuance) and reserve the right to adjust prices based on market conditions thereafter; **Raw Material Baseline**—state the specific raw material price used as the baseline and advise the client to lock in the price immediately after the quote is issued; **Linkage Mechanism**—base the product price on the cost of specific raw materials (e.g., “XX Material”), stipulating that if the material price fluctuates by more than 5%, both parties share the excess cost 50/50 and the product price is adjusted accordingly; **Advance Notice**—require 30 days’ written notice for any price adjustment, with the increase for a single batch capped at an agreed limit; **Phased Adjustments**—if a price hike is inevitable, negotiate small, incremental adjustments—treating the quote as dynamic so that material linkage clauses allow the price to move in sync with costs.
Conclusion
Will prices change when raw material costs rise for non-standard assembly lines?
The conclusion is: “It depends on the contract”—fixed prices mean you absorb the cost; linkage clauses mean adjustments follow a formula; and the absence of an agreement invokes the “change of circumstances” doctrine. **Check the Contract**—fixed-price clauses mean you bear the cost difference (real-world cases show factories absorbing costs when material prices rose multiple times on orders placed in the first half of the year), while adjustment clauses dictate how changes are made. **No Agreement**—Article 533 of the Civil Code (change of circumstances) applies; if renegotiation fails, one can petition the court to modify or terminate the contract, though this entails high costs. **Linkage Clauses**—define the anchor point (material type, specifications, and reference date), formula (adjusted price = baseline price × index ratio), threshold (no change within ±5%; settlement based on actuals if exceeded), and cycle (monthly/quarterly effective dates). **Price Locking**—quarterly or annual price-lock agreements, floating ranges, price comparisons with alternative suppliers, and price-rollback clauses. **Basis for Price Hikes**—15 days’ written notice, market data/procurement records, and phased adjustments.
Industry convention holds that rising raw material costs are not a matter of right or wrong, but of contractual clarity—clearly stipulate shared risk for price fluctuations, or face disputes when prices rise.
