Scrap carbide price

The price of scrap carbide is primarily driven by its Tungsten (W) and Cobalt (Co) content. Higher-grade scraps, such as solid carbide end mills and drills, command higher prices compared to carbide sludge or grinding dust. Additionally, global commodity market fluctuations for Tungsten (APT prices) and the purity of the scrap (absence of steel attachments or brazing material) are critical price determinants.

Buyers should categorize scrap into three main tiers: Grade A (Solid Carbide) which includes clean inserts and tools; Grade B (Mixed Scrap) which may have steel shanks or attachments; and Grade C (Soft Scrap) such as powders and turnings. Separating these grades before requesting a quote ensures more accurate pricing and prevents suppliers from applying a 'lowest common denominator' price to a mixed lot.

While it is a waste product, international trade requires compliance with the Basel Convention regarding the transboundary movement of hazardous waste (if the scrap contains specific heavy metal residues). Buyers should verify the chemical composition analysis (XRF testing) provided by the seller to ensure the Tungsten content meets the 80-90% threshold typical for high-quality scrap.

Recycled carbide is processed through zinc recovery or chemical leaching to produce reclaimed Tungsten Carbide powder. This powder is then used to manufacture new cutting tools, wear-resistant coatings, and mining bits. For industrial buyers, sourcing scrap is a cost-effective and sustainable alternative to virgin raw materials, aligning with ESG (Environmental, Social, and Governance) goals.

The most significant risk is material substitution or contamination, where heavy non-carbide metals (like lead or iron) are mixed in to increase weight. To mitigate this, always insist on third-party inspection (such as SGS or CCIC) at the loading port to verify weight and material purity before final payment.

Negotiations should be based on LME (London Metal Exchange) or MB (Metal Bulletin) indices. A professional strategy is to propose a formula-based pricing model (e.g., % of the current APT price per kg of contained Tungsten). This protects both parties from volatile market swings during the shipping period.

Use secure payment terms such as a Letter of Credit (L/C) or platforms like Made-in-China.com's secured trading services. Avoid 100% T/T advance payments for new suppliers. Ensure the Bill of Lading (B/L) matches the weight recorded on the official weighbridge certificate to prevent 'short-weighting' scams.

Scrap metal is often subject to strict customs scrutiny. Ensure the HS Code (typically 8101.97 for Tungsten waste and scrap) is correctly declared. Buyers must check if their country requires an Import License for Solid Waste. For shipping, use heavy-duty reinforced drums or bags to prevent leakage, as carbide is dense and can easily damage standard packaging during maritime transit.
